Semi-distributed modelling of the monthly water balance in an alpine catchment

The need for estimates of distributed water balance in alpine catchments is addressed. Such estimates are an essential prerequisite for the efficient planning and management of water resource use. Specifically, the maximum appropriate spatial resolution that can be obtained in water balance estimates is assessed, given limited information of physiographic parameters and meteorological variables, in a complex topographical environment. This is done using a combination of existing modelling methodologies. The use of spatial disaggregation into subregions of similar climatic and topographic..
