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
