Stu Hamilton (Author, Hydrology Corner Blog) and Martin Doyle (Tasman District Council) contemplating the New Zealand landscape from the perspective of the Old Ghost Road.

Ray Maynard calls me a peripatetic hydrologist. I had to look it up. There are two meanings: 1) a person who travels from place to place or 2) an Aristotelian philosopher. I think I fit both definitions. Aristotle placed great emphasis on direct observation of nature and that theory must follow fact. I also travel a lot. Whereas I can’t deny this label, I have...

Banner for International Hydrometry Workshop.

In the field of hydrometry there is benefit that arises from global collaboration. Few monitoring agencies have enough resources needed to invest in wide-ranging discovery of better ways for acquiring and producing streamflow data. However, it is feasible for local centres of expertise to develop that can advance any one of many opportunities for significant advancement in the business of water measurement and monitoring....

Illustration of international rating curve standards.

Stage-discharge rating curves define a unique relation between water level and discharge, enabling continuous derivation of streamflow from water level record. This is important because water level (which is relatively easy to monitor) is only locally relevant whereas discharge (which is relatively difficult to measure directly) is the integral of all runoff processes upstream of the gauge. The vast majority of all streamflow data that...
