“…Each cell is divided into several hydrological response units (HRUs) based upon the soil description, the slope, landuse and meteorological data. The HRUs are simulated separately and the outputs of a cell are the weighted average of the HRU's outputs (Bauwens et al, 2011). Validation of the model is available in Sohier et al (2009) andDegré (2010).…”

“…This was performed using the perturbation tool CCI-HYDR developed by Ntegeka et al (2014) and previously used by Bauwens et al (2011). Based on the results of regional climate models (RCMs) and global circulation models (GCMs), it applies an advanced perturbation method to perturb the measured time series of temperature and precipitation.…”

“…The number of different water uses considered in these studies was generally limited to two or three aspects, such as hydropower and floods (Bieri and Schleiss, 2013;Jordan et al, 2012), hydropower and minimum environmental flow or energy production, low-flow augmentation and flood support for agricultural purposes (Bader et al, 2003). In contrast, Fortin et al (2007) performed a combined analysis of the reservoir system performances in terms of flood control, leisure activities, hydropower and ecology.…”

“…As shown by their results, climate change tends to increase competition between different water uses; but adaptation of the reservoir management can make a substantial difference by contributing to reach more acceptable new trade-offs between the competing water uses. Other types of scenarios considered in previous studies include growing water demand for irrigation (Bader et al, 2003) or the upgrade of the reservoir system by dam heightening (Bieri and Schleiss, 2013;Bieri et al, 2011).…”

Abstract. According to available climate change scenarios for Belgium, drier summers and wetter winters are expected. In this study, we focus on two multi-purpose reservoirs located in the Vesdre catchment, which is part of the Meuse basin. The current operation rules of the reservoirs are first analysed. Next, the impacts of two climate change scenarios are assessed and enhanced operation rules are proposed to mitigate these impacts. For this purpose, an integrated model of the catchment was used. It includes a hydrological model, one-dimensional and two-dimensional hydraulic models of the river and its main tributaries, a model of the reservoir system and a flood damage model. Five performance indicators of the reservoir system have been defined, reflecting its ability to provide sufficient drinking water, to control floods, to produce hydropower and to reduce low-flow conditions. As shown by the results, enhanced operation rules may improve the drinking water potential and the low-flow augmentation while the existing operation rules are efficient for flood control and for hydropower production.

Hydrological models have been widely used to assess changes in stream discharges by climate change; however, concern might arise on the accurateness of the model predictions under the changed conditions particularly during low flow periods. In this study, two spatially distributed hydrological models MIKE SHE and WetSpa, each representing a different model complexity in terms of process description, data needs, parameter space, degree of calibration, were compared in their estimation of the climate change impact on the flow regimes in a medium-sized catchment in Belgium. The fully integrated, physically based MIKE SHE model, comprising a three-dimensional groundwater flow and river model, was applied to better understand the groundwater flow and groundwater-river interactions under changed climate conditions. Both models were able to capture the flow dynamics very well with high efficiencies and simulated the flow extremes very accurately. The groundwater heads in MIKE SHE and their seasonal variation had a high model performance. The two models simulated similar changes to future flows because of climatic changes. Peak flows were expected to increase or decrease depending, taking the large uncertainty in future climate trends into account. The model structural uncertainties on these high flow predictions were rather limited. Low flows were expected to reduce because of drier conditions by future climate change, indicating elevated low flow risks for Belgium. However, the projected low flow changes differed significantly over the models and even exceeded the uncertainty by the expected climate trends. Smaller impact was predicted by considering the groundwater physics and river interaction in the MIKE SHE model. These changes to the surface water regimes were verified by the changes in groundwater heads. Future groundwater conditions also point towards drier conditions with a small decrease in heads for future summer and autumn periods. Projected variations in winter heads depend on the climate scenario.

Abstract:In this study, we investigated the responses of hydrology and sediment yield with impacts of land-use and climate change scenarios in the Be River Catchment, using the Soil and Water Assessment Tool (SWAT) hydrological model. The calibration and validation results indicated that the SWAT model is a powerful tool for simulating the impact of environmental change on hydrology and sediment yield in this catchment. The hydrologic and sediment yield responses to land-use and climate changes were simulated based on the calibrated model. The results indicated that a 16.3% decrease in forest land is likely to increase streamflow (0.2 to 0.4%), sediment load (1.8 to 3.0%), and surface runoff (SURQ) (4.8 to 10.7%) and to decrease groundwater discharge (GW_Q) (3.5 to 7.9%). Climate change in the catchment leads to decreases in streamflow (0.7 to 6.9%) and GW_Q (3.0 to 8.4%), increase in evapotranspiration (0.5 to 2.9%), and changes in SURQ (À5.3 to 2.3%) and sediment load (À5.3 to 4.4%). The combined impacts of land-use and climate changes decrease streamflow (2.0 to 3.9%) and GW_Q (12.3 to 14.0%), increase evapotranspiration (0.7 to 2.8%), SURQ (8.2 to 12.4%), and sediment load (2.0 to 7.9%). In general, the separate impacts of climate and land-use changes on streamflow, sediment load, and water balance components are offset each other. However, SURQ and some component of subsurface flow are more sensitive to land-use change than to climate change. Furthermore, the results emphasized water scarcity during the dry season and increased soil erosion during the wet season.
