| Abstract: | The SWAT model was applied to the Ompólveda River Basin
(Guadalajara, central Spain) to assess the hydrological feasibility of
the Pareja Limno-reservoir. A limno-reservoir is a water management
infrastructure designed to counteract some negative impacts caused
by large reservoirs under Mediterranean climate. Highly detailed
inputs were selected to set up the model. Its performance was
evaluated by graphical and statistical techniques and compared with
the previous knowledge of the basin. An overall good performance
was obtained during the calibration and validation periods (monthly
and annual NSE values of 0.67 and 0.60, respectively, for calibration
and 0.70 and 0.83, respectively, for validation). Total discharge was
well simulated, and flow components prediction was acceptable.
However, the model is not accurate at predicting evapotranspiration.
Once evaluated, the model was used to simulate the water discharge
into the Pareja Limno-reservoir during 2008 and 2009, establishing
a water balance and assessing its hydrologic feasibility. The water
balance predicted the absence of surplus during summer (2008 and
2009) and autumn (2009), matching up with the decrease of water
level and demonstrating the usefulness of SWAT as a tool to evaluate
the hydrologic feasibility of the Pareja Limno-reservoir. Very low
discharges from the Ompólveda River after a sequence of normal
and dry years are the main factors responsible of this phenomenon,
whereas the effect of the wastewater flow redirection in the Pareja
village is negligible. These results question the usefulness of the
Pareja Limno-reservoir during summer, the most favorable season
for recreational activities. |
