Hydrologic Model

• TOPMODEL (Beven and Kirkby, 1979 and later) applied to each subwatershed.
• Temperature and radiation based potential (reference) evapotranspiration.
• Vegetation based interception component.
• Modified soil zone
  • Adjust ET based on soil moisture availability in root zone
  • Infiltration excess runoff generation capabiity
  • unsaturated storage and drainage
• Parameters scaled by GIS average properties over each subwatershed.
• Kinematic wave routing of streamflow through channel network.
