Reach Scale Hydrology

About

This website serves as a catalogue (i.e. portal instead of host) of tools, data, and references for researchers and stakeholders interested in reach scale hydrology. The term "reach" refers to a segment of river between points of confluence/bifurcation (or channel initiation) and its contributing area. The length of a river reach varies with factors like climate, topography, geology, as well as channel definition (channelization criteria), and the length usually ranges from 1 to tens of kilometers. We consider the "reach scale" an important intermediate and bridge between "catchment scale" and "field scale" that offers finer details than the former thanks to the booming of "big data" in geosciences while being better understood than the latter as many assumptions and approaches for lumped hydrologic modeling may still work reasonably well.

Commonly used hydrologic models, river routing models, calibration tools, bias correction tools, etc.

Static parameters for modeling/analysis like river/catchment hydrography, river properties, catchment climatology, etc.

Long-term data records for land surface runoff, river discharge, flood and risk analysis, hydrologic drought, etc.

Near real time monitoring, short-term, seasonal forecast, reforecast/hindcast
