SNOWMELT-RUNOFF MODEL STREAM FLOW FORECASTS
2009/10/29
Following the development of rainfall-runoff models the attention of the
international hydrologic program is now increasingly focused on the snowmelt-
runoff. The present simple model is based on ta...
Runoff is a difficult variable to map because the information from river
gauging stations only indicates average runoff from the catchment area
above the gauging point. A method of mapping runoff by...
