Resumen
In the Vallcebre catchments (NE Spain, 42º 12’N, 1º 49’E), climatic data and hydrometric records at the outlet of the catchments have been complemented with measurements of internal states and fluxes, such as depths to the water table, soil water content, forest rainfall interception and tree transpiration. The semi-distributed TOPBAL model has been implemented in the Can Vila research catchment for analysing and generalising these data. TOPBAL considers two drivers of hydrological similarity: topography and vegetation type. The model simulates rainfall interception by vegetation, the control of soil moisture on evapotranspiration, and two-way exchanges between the root-unsaturated and the phreatic stores. When the model was constrained with flow data criteria (discharge, log-discharge, inverse of discharge and water balance) the results were acceptable but there was a large equifinality due to the compensation between parameters. Data on soil water contents and depths to the water table helped to reduce parameter compensation but local controls on soil and aquifer responses limited the quality of simulations.
