Effects of “ENSO-events” and rainforest conversion on river discharge in Central Sulawesi (Indonesia)

Forest conversion and natural interannual climate fluctuation as ENSO-events are key determinants of water balances in tropical catchments. Distributed hydrological modelling that relates land cover changes and climate changes with river discharge are rare for humid tropical catchments at the mesoscale. In the present paper we present a hydrological modelling approach to describe the impact of land cover changes and ENSO-events on the water resources in a mesoscale humid tropical catchment. These are based on hydro-meteorological measurements that were performed in the Gumbasa catchment from 2002 to 2005 in the frame of STORMA.
