CALIBRATION, VALIDATION AND EVALUATION OF A LUMPED HYDROLOGIC MODEL IN A MOUNTAIN AREA IN SOUTHERN ECUADOR

The performance of the Temez lumped model is evaluated in six (6) basins located in the border region between Ecuador and Peru, in South America. The basin areas vary between 200 and 2642 km2. Precipitation and temperature recorded in 43 climatological stations in the study area were considered. For...
