Selected Activities Hydrological Model
Climate and Hydrologic Models Regional Climate Model REMO Hydrological Model WASA Scenarios of water availability up to 2100
Hydrological Model WASA Climate forcing River basin water balance Model output: Time series of water availability variables Processes represented in WASA: Infiltration Soil water movement Evapotranspiration Runoff generation Runoff routing in river network Retention in reservoirs Model extension in CAWA project: Snow melt Glacier mass balances
Hydrological Model WASA Examples of required parameters Topography: Slope gradient Slope length River cross sections from Digital Elevation Models hillslope with terrain components Soil profile stream net twork TC 1 TC 2 TC 3
