A Question of Scale – Reconciling Information Density with Information Scarcity

Laboratory analysis of a water quality sample links a lot of data to a singular point in time and space. However, the objectives for monitoring may span scales from point (e.g. at an outfall) to watershed (e.g. to characterize waters; identify trends; assess threats; inform pollution control; guide environmental emergency response; and support the development, implementation, and assessment of policies and regulations).

A Question of Scale: Reconciling Point-Scale Observations With Watershed-Scale Outcomes

Laboratory analysis of a water quality sample links a lot of data and metadata to a singular point in time and space. However, the objectives for monitoring may span spatial and temporal scales from point sampling (e.g. at an outfall) to watershed assessment (e.g. to characterize waters; identify trends; assess threats; inform pollution control; guide environmental emergency response; and support the development, implementation, and assessment of policies and regulations). Reconciling data- and metadata-dense analytical results with watershed-scale outcomes is a work-in-progress for many monitoring agencies.

Hydrology as a Global-Scale Science

I often refer to hydrology as a place-based science There are very many processes that can come into play in the hydrological cycle of which only a subset is relevant at any given location. There can be synergistic, neutral or antagonistic process interactions within any given subset. The net result is that every landscape requires…
