Abstract: | Climate change is an important issue for water management in the coming decades and it is expected that problems will occur due to climate change. This research will be about the amount of low flows which is expected to increase as a consequence of climate change. For the determination of a low flow, two indicators are used; the total summer deficit and the threshold for navigation purposes. The threshold for navigation is set at a 1000 m3/s at Lobith, the Netherlands. These indicators are based on the LCW values. Based on the two indicators the severity of low flows can be determined. For the simulation of the discharge at Lobith, a standalone version of the HBV model is used (FEWS). This model has a NS of 0.92, NSLOG of 0.92 and a RVE of 2% for a simulation with observed climate data for 1962-1992. This is a good simulation. The effects of the different climate change scenarios have been assessed with this model.In the research four different steps have been conducted. One of the steps is to assess the effects of the HBV model on the different low flow indicators. The other step is to assess the effect of the RCM driven with GCM data for the control run on the different indicators; the final step is to assess the effect of climate change. This will be done by comparing the period 1962-1992 with 2070-2100 for a certain RCM driven with GCM data as input to the HBV model |
