A tool to integrate physical hydrology, irrigation demand, and water management for climate change research

Hydrology Model

Critical question: How does rainfall on a catchment translate into flow in a river?

Critical question: What pathways does water follow as it moves through a catchment? Runoff? Infiltration? ET? Seepage?

Critical question: How does movement along these pathways impact the magnitude, timing, duration and frequency of river flows?

Planning Model

Critical question: How should infrastructure (e.g. dams, diversion works, etc) be operated to achieve maximum benefit? How should water be allocated in shortage?

Critical question: How operations be optimized to protect the services provided by the river?

Critical question: How will allocation, operations and operating constraints change if new management strategies are introduced into the system?

Integrated  Water  Resource  Management  

•  Integrated watershed hydrology and water planning model

•  GIS-based, graphical drag & drop interface. •  Physical simulation of water demands and supplies. •  Additional simulation modeling: user-created

variables and modeling equations. •  Scenario management capabilities. •  Seamless watershed hydrology, water quality and

financial modules •  SEI-US.org, NCAR, AwwaRF, USEPA
