Assessing Climate Change Impact on Water Resources in Water Demand Scenarios Using SWAT-MODFLOW-WEAP

نویسندگان

چکیده

In this article, we present the use of coupled land surface model and groundwater flow SWAT-MODFLOW with decision support tool WEAP (Water Evaluation Planning software) to predict future surface-water abstraction scenarios in a complex river basin under conditions climate change. The modelling framework is applied Dee River catchment Wales, United Kingdom. Regarding hydrology, improves overall water balance low-streamflow compared stand-alone SWAT model. calibrated employed high-resolution data from UKCP18 project scenario RCP85 2020 2040. Then, supply results are fed into as input for reach downstream region basin. This system utilized create various public region—maximum licensed withdraw, 50% authorized abstractions, monthly time series 1% increases use, maximum withdraw per year based on historical records repeated every use—to estimate unmet demands streamflow requirement. approach can be used other basins manage demand.

Assessing the Impacts of Climate Change, Urbanization, and Filter Strips on Water Quality Using SWAT

Precipitation changes and urban growth are two factors altering the state of water quality. Changes in precipitation will alter the amount and timing of flows, and the corresponding sediment and nutrient dynamics. Meanwhile, densification associated with urban growth will create more impervious surfaces which will alter sediment and nutrient loadings. Land and water managers rely on models to d...
