Centralize All Your Environmental Data

Environmental data comes from many sources and in many forms. AQUARIUS Time-Series allows you to centralize vast amounts of hydrologic time series data, discrete measurement data, and complex river gauging measurements from various locations. It makes it easy to integrate, import, and enter data quickly, so you can effectively manage all your environmental information on one platform.

Centrally Manage Your Monitoring Network Locations  |  The central concept in AQUARIUS Time-Series is a monitoring location. A location houses time series datasets, rating models, field visits, and other data as needed. Location information includes geospatial coordinate and datum details, agency ID numbers, user access rights, and attachments of files and images. Using the AQUARIUS Data Connector, location information and other data such as field visits and time series can be synchronized from an external system, if that is where they are stored and managed. Location information can also be extended as needed, adding items like phone numbers, drainage areas, or funding status.

Integrate with Data Acquisition Systems  |  There are many options for integrating AQUARIUS Time-Series with data acquisition systems. It can be deployed with many off-the-shelf telemetry systems such as Campbell Loggernet, YSI Econet, Unidata NEON, and the Sutron DCSToolkit. AQUARIUS Time-Series also works seamlessly with AQUARIUS EnviroSCADA, the most robust data acquisition software used by leading water and environmental monitoring agencies worldwide. Alternatively, you can integrate AQUARIUS Time-Series with a data acquisition system through the use of a comprehensive web services API.

Import Data Logger Files Quickly & Automatically  |  AQUARIUS Time-Series allows you to quickly upload or append data from different data logger file formats (including Sutron, PDAS, Vedas, YSI, Text, and CSV). No matter how your data is delimited or formatted, AQUARIUS Time-Series can sort through the file and ingest your data. AQUARIUS Time-Series simplifies data imports by monitoring for any new data logger files. When new data logger files arrive, AQUARIUS Time-Series automatically parses the file and appends the data to the correct time series.

Import Hydrometric Gauging Measurements  |  AQUARIUS Time-Series provides a powerful tool for ingesting hydrometric measurement data. You can easily import, visualize, and edit discrete hydrometric field data (such as benchmark level surveys, gauge height readings, area-velocity, and ADCP stream flow measurements). It supports direct import from common field computer formats including AquaCalc, Flowtracker, ADCP WinRiverII, Water Survey Canada HFC, and USGS HydroML. Data can also be hand entered from field forms as needed.

Deliver the Best Quality Data

Data consumers want real-time data they can trust. AQUARIUS Time-Series has a unique portfolio of features for real-time sanity checking, error detection, data cleaning, data flagging, automatic bias corrections, and rating shift management. Automated procedures eliminate the majority of tedious manual data workup processes. By automating quality assurance and quality control activities, you can free up time for higher value analysis. Real-time email warnings of unusual events support timely action.

Edit & Correct Time Series  |  Records from remote environmental monitoring stations usually contain some anomalous or erroneous data, like sensor drifts. To ensure the highest quality of published data these anomalous records need to be quality controlled. AQUARIUS Time-Series provides an easy to use and rigorous graphical data correction and editing environment. Spike removals, drift adjustments, and pro-rated percent corrections are just a few of the many data correction tools available. The powerful audit log automatically tracks all changes.

Automatically Correct for Sensor Drift & Fouling  |  Intelligent quality control logic allows AQUARIUS Time-Series to review your field visit data and suggest appropriate corrections to correct for sensor fouling and calibration drifts. Customizable policies enable single-click application of complex corrections to ensure that the best possible water data are maintained!

Automate Quality Assurance & Controls in Real-Time  |  Automate quality assurance and quality control activities to optimize the quality of your real-time data. AQUARIUS Time-Series can automagically remove spikes that are not physically possible through parameter and unit-specific sanity checks. Automate on-going corrections to remove values that might be physically possible, but are nonsensical for the specific monitoring location. On-going corrections obey the same rules as all other data edits in AQUARIUS Time-Series: they are logged, audited, and can be reversed at any time.

Defend Your Data Easily

Defensible data and work records are vital to ensuring you have the best possible data. AQUARIUS Time-Series automatically builds a data processing, correction, and editing log, providing the transparency you need to defend your data. The audit log tracks all corrections, quality codes, and notes for time series data. You can review a log to quickly find who performed what, when, and why. Data corrections can be undone at any time, allowing you to see the values affected.

Defend & Retrace Data with the Automatic Audit Log  |  AQUARIUS Time-Series safeguards all of your original data. A user can never edit the raw data. The powerful AQUARIUS Data Correction toolbox records all changes in a reversible change stack. All edits, corrections, grades, approvals, metadata, and notes are non-destructive and fully logged in the session-independent undo/redo audit track. The completeness of the audit log allows you to re-construct a time series “as of” any time in the past. This feature makes it easy for you to defend your decisions, since data can be rolled back in time to show exactly what corrections were applied at any point in history.

Track Data Quality with Grades, Qualifiers & Flags  |  AQUARIUS Time-Series also allows you to assign data grades such as “Good” or “Poor.” Grades can be imported with the data (if sensors and acquisition systems assign quality grades to data) or can be assigned manually. Grades propagate automatically through calculations and derivations, affecting the outcome of aggregations. Grades are available for reporting and displayed as small markers next to each value. The list of grades can be fully customized. Flags are used to highlight objective events or data qualifiers, such as “rate of change exceeded” or “threshold exceeded.”

Set Workflow Controls & Approvals  |  Approval levels track the status of your data during processing, from raw to corrected to publish-ready. You can customize approval levels for your organization, and use them on time series data, ratings, and field visits. AQUARIUS Time-Series protects your approved data with data snapshots to ensure they will not change. Once approved you can rest easy knowing your published data are safe and secure.

Build the Best Rating Curves

Building rating curves can be a complex task. A single rating for your channel contains ratings, shifts, blends, and periods of applicability that describe a channel as it changes over time. The AQUARIUS rating development tool is the gold standard to support the latest global standards set by the USGS, ISO, WMO, and OGC. It is used by national agencies like the USGS to efficiently develop accurate and legally defensible ratings and to ensure the highest confidence in their calculations of flow.

Build Stage Discharge Rating Models  |  The development of river stage versus discharge curves is a key step in any hydrographer’s work. Field measurements, cross sectional survey data, and dynamic river conditions (such as backwater, scour, fill, and weed growth) all have to be taken into account when calculating discharge. The accuracy of your computed discharge data is critically dependent on your rating curves. AQUARIUS Time-Series puts all the information you need at your fingertips so you can be confident in the rating curves that you build.

Follow the Standards  |  The science and art of drawing rating curves has been fine-tuned over 100+ years of dedicated work by the world’s leading hydrometric agencies. International standards have been developed and published by the International Organization for Standards (ISO), the World Meteorological Organization (WMO), and in US Geological Survey (USGS) Technical References. AQUARIUS Time-Series allows you to conform to these standards – it is the tool used by the very agencies who are the leaders in writing the international standards. The AQUARIUS Time-Series rating curve development environment is the tool used by the USGS, Water Survey Canada (WSC), the National Institute of Water and Atmospheric Research (NIWA), and a host of other leading organizations for the development and maintenance of their stage versus discharge curves.

Shift or Blend Your Rating Curves Easily  |  Calculating accurate river flows from a rating curve means adjusting the curve to account for changes to river controls like scour, fill, debris, ice, and plant growth. This has traditionally been time consuming, often involving re-drawing an entire curve or tweaking with least squares fitting weights. AQUARIUS Time-Series makes this easy, so you can focus on the hydrology. Shift adjustments to a rating curve can be drawn quickly. Rating shifts can be applied as constants or can be phased in through time to avoid jumps in the calculated hydrograph. Individual rating curves within the model can be blended (prorated) from one to the next for smooth transitions.

Compute Index Velocity in Real-Time  |  While stage discharge ratings are the most commonly used method to derive flow calculations, over 30% of water professionals today use the index velocity method to measure the flow of water in complex environments like backwater, tidal flow, bi-directional flow, reversing flow, small-gradients, and rapid flow. AQUARIUS Time-Series can be used to perform index velocity computations in real time with a combination of rating derivation (for stage-area) and calculated time series (for mean velocity and discharge). Applying stage-area and mean velocity ratings to incoming data automatically computes discharge.

Calculate & Visualize Derived Data in Real-Time

Calculated data is essential for getting the most information from your monitoring network. A powerful set of processing tools automate workflows and streamline data production. AQUARIUS Time-Series can mix data input sources, build sophisticated multi-input models, run rating curves, calculate daily aggregates, and fill gaps in your data. All derived data are calculated in real-time and available to publish within seconds after raw data are detected in the field.

Derive Statistics from Time Series & Visualize Meteorological Data  |  Calculating and reporting on statistical values that are derived from a time series can be done quickly. AQUARIUS Time-Series allows users to calculate a myriad of derived statistical summary values and to have these values form a new time series. Certain data types require special treatment when it comes to data visualization. Examples of these types of data are rainfall accumulations and intensities. AQUARIUS Time-Series helps you visualize all types of data, for example, displaying raw and corrected precipitation on a single chart.

Manage Parameters, Units, Methods & Grades  |  AQUARIUS Time-Series is designed to support data management best practices. All commonly measured environmental parameters and units are built in. SI and English units can be easily converted and new parameters can be added to facilitate conversions into other parameters through integration, aggregation, or rating curve transformations. Many computed parameters, such as total runoff and maximum rainfall intensity, require special data interpolation methods. Standard interpolation types are supported, including instantaneous values, total in preceding interval, discrete values, and accumulating values. This allows you to compute data even when values are sparse or need to be extrapolated to a boundary. AQUARIUS Time-Series also tracks time zones making it easy to manage networks of stations that span time zones.

Publish Data in Real-Time

Today’s stakeholders demand timely data. AQUARIUS Time-Series allows you to publish your data based on an extensive list of industry standard report templates. Reports can be run ad-hoc or on a schedule. Streamline regulatory reporting and deliver the information needed to better manage precious water resources. Get the right information, to the right people, at the right time.

Generate Reports in Seconds  |  Turn raw data into actionable information in seconds to better manage your precious water resource. Print-ready reports are a key deliverable for ongoing operations and regulatory compliance requirements. AQUARIUS Time-Series allows you to quickly generate reports from a large list of industry templates. Reports can also be populated with machine-readable data and retrieved programmatically through the AQUARIUS Web Service APIs.

Publish Your Quality Data to the Web in Real-Time  |  AQUARIUS Time-Series integrated seamlessly with the optional AQUARIUS WebPortal, empowering your organization to publish high quality environmental data in real-time to the web in a comprehensive, virtual earth-map user environment. An event-driven computation engine ensures that all data are kept up to date whenever new data is appended, rating curves are edited, or time series are corrected. If your organization already has a public data portal website, the AQUARIUS can be used as a data source for real-time data dissemination through its web service (REST) – your organization can reuse its existing website front end code with the new real-time data from the AQUARIUS.

Protect Your Investment

Investments in modern software should pay back dividends for years to come. A modern architecture makes AQUARIUS Time-Series scalable from a single user to a national team managing thousands of stations. Simply add users and integrate new data sources as your monitoring program grows. User access privileges and server failover systems keep your data secure and safe. Water monitoring records can be over 100 years long – you can rely on AQUARIUS Time-Series to protects your data

Choose a Scalable Standards-Based Architecture  |  The AQUARIUS Time-Series is a fully scalable, modern enterprise platform. It can be deployed on a national level, managing thousands of stations and users, or to a single user faced with managing a few real-time stations. Supported scripting languages (C# and VB.NET) are standard .NET languages, eliminating the need to learn proprietary languages. All external interfaces to the system are easily accessed via SOAP and REST web services.

Centralize & Optimize Your Database Storage  |  AQUARIUS Time-Series stores all your data in a single central database optimized to handle the high traffic demands of continuous monitoring programs. Huge time series can be appended and queried hundreds of times faster than from conventional relational database storage systems. Concurrency and data version control ensure that users working on data are accessing the latest data and cannot overwrite each other’s changes. Data are stored in either an Oracle or MS SQL database in a straightforward schema designed with readability in mind. Access to data is via a set of comprehensive and well-documented SOAP and REST web service APIs.

Control Access & Keep Your Data Secure  |  AQUARIUS Time-Series gives organizations full control over data and system access. The configurable access control module allows for both simple and highly complex security models. Administrators determine which users can edit data at certain approval levels. Users can be assigned to specific locations. Functional-level access control can also restrict access to administration controls. MS Windows Domain Authentication can be used for additional convenience – the single sign-on is matched to your corporate security standards for password reuse and strength.

Control Workflows & Approvals  |  AQUARIUS Time-Series tracks data through the production process. You can configure precise workflow controls over data as they move through the production system, from unchecked telemetry, to automated quality control, into user editing and correction, and on to peer review and final approval. AQUARIUS Time-Series features a unique concept called Approval Levels that are applied to indicate the level of processing and review data has received. Certain users are only able to edit data at certain approval levels based on user roles and data access privileges. Likewise, approvals control when data is published. Final data can be published in real-time, while data in manual workup can remain hidden. This workflow can be easily scaled up or down for large or small organizations as required.
