Discharge, allocation, scarcity and flood on one reach
Water security covers how much water a catchment delivers, who it is allocated to and what happens in a dry or a wet year.
The subtopics its courses and labs teach.
Courses in development extend the scope to further subjects: Groundwater and aquifer risk; Transboundary water risk and cooperation.
Search any place or open the world; the layers and generators follow water security and hydrology on the planet map, the globe and in 3D.

Annual rainfall and evaporative demand set how much of a catchment’s water reaches its rivers; withdrawals set against that runoff, after the share rivers need, give the water stress indicator; the allocation decision follows from the stress, not from the rainfall alone.
