| Abstract | This paper presents a simple model to estimate the water balance for a watershed from within a GIS. The model is based on the Thornthwaite-Matter water balance and uses rain gage station data and daily AVHRR images as inputs. The model was applied for the Ji-Parana (RO - Brazil) basin at 1km spatial resolution and a monthly time step, from February 1995 to December 1996. Results were compared with annual discharge data for 10 sub-basins showing that, on average, annual evapotranspiration (ET) was sub estimated by 9%, and water surplus was super estimated by 17%. The ET of the Ji-Parana basin was estimated to be 1166 mm year -1 , roughly 3.2 mm day -1 , ranging from 1.7 mm day -1 in July and August to 4.5 mm day -1 in October. |
