2.2 Study area
Based on hydrometeorological and underlying surface change data, a distributed hydrological model, the geomorphology-based hydrological model (GBHM) (Yang et al., 2001; Yang et al., 2002), was established. The parameters employed in the creation of the model were calibrated and the effects of the simulation were evaluated. Based on the model, changes in hydro–logical characteristics and meteorological factors of the basin caused by the construction of reservoirs were explored and highlighted. Changes in the peak flood volume and sediment discharge that are related to the operation of reservoirs and other soil and water conservation measures in the basin were discussed. In addition, the impacts of the construction of reservoirs on the ecology of the basin were also examined. The research framework is shown in Figure 2.
