| Summary: | Drought and water shortage effects are normally
exacerbated due to collateral impacts on water quality, since low streamflow
affects water quality in rivers and water uses depend on it. One of the most
common problems during drought conditions is maintaining a good water
quality while securing the water supply to demands. This research analyses
the case of the Turia River Water Resource System located in Eastern Spain.
Its main water demand comes as urban demand from Valencia City, which intake
is located in the final stretch of the river, where streamflow may become
very low during droughts. As a result, during drought conditions
concentrations of pathogens and other contaminants increase, compromising
the water supply to Valencia City. In order to define possible solutions for
the above-mentioned problem, we have developed an integrated model for
simulating water management and water quality in the Turia River Basin to
propose solutions for water quality problems under water scarcity. For this
purpose, the Decision Support System Shell AQUATOOL has been used. The
results demonstrate the importance of applying environmental flows as a
measure of reducing pollutant's concentration depending on the evolution of
a drought event and the state of the water resources system. |
