Groundwater recharge simulation using a coupled saturated-unsaturated flow model
Abstract The coupled MODFLOW-HYDRUS software package was used to produce a saturated-unsaturated flow model for a Flood Spreading System (FSS) and its associated aquifer. The study aim to improve simulations of near-surface hydrological processes, including temporal and spatial variation in groundwater recharge rates. The coupled model was built with average RMSE=1.1 and 1.3 for calibration ...
متن کاملModelling Hydrology of a Single Bioretention System with HYDRUS-1D
A study was carried out on the effectiveness of bioretention systems to abate stormwater using computer simulation. The hydrologic performance was simulated for two bioretention cells using HYDRUS-1D, and the simulation results were verified by field data of nearly four years. Using the validated model, the optimization of design parameters of rainfall return period, filter media depth and type...
متن کاملArtificial recharge of groundwater: hydrogeology and engineering
Artificial recharge of groundwater is achieved by putting surface water in basins. furrows, ditches, or other facilities where it infiltrates into the soil and moves downward to recharge aquifers. Artificial recharge is increasingly used for shortor long-term underground storage. where it has several advantages over surface storage, and in water reuse. Artificial recharge requires permeable sur...
متن کاملRecharge estimation and soil moisture dynamics in a Mediterranean, semi-arid karst region
Knowledge of soil moisture dynamics in the unsaturated soil zone provides valuable information on the temporal and spatial variability of groundwater recharge. This is especially true for the Mediterranean region, where a substantial fraction of long-term groundwater recharge is expected to occur during high magnitude precipitation events of aboveaverage wet winters. To elucidate process unders...
متن کاملAssessing controls on diffuse groundwater recharge using unsaturated flow modeling
[1] Understanding climate, vegetation, and soil controls on recharge is essential for estimating potential impacts of climate variability and land use/land cover change on recharge. Recharge controls were evaluated by simulating drainage in 5-m-thick profiles using a one-dimensional (1-D) unsaturated flow code (UNSAT-H), climate data, and vegetation and soil coverages from online sources. Soil ...
