Effects of Hybrid-Type Artificial Groundwater Recharge and Underground Barrier in a Small Basin

Climate change is exacerbating water shortages in upstream basins the Korean peninsula that lack agricultural supply systems. The basin investigated this study requires an extra 208 m3·d?1 of during May (the busiest month for agriculture). purpose was to assess a hybrid-artificial recharge and circulation system, which composed hybrid-recharge source re-infiltration pumped field, estimate yield capacity by field injection test numerical model. Injecting pretreated stream 42 d increased groundwater levels basin. Water budget analysis MODFLOW simulations revealed injecting as well discharge due terrain’s gentle slope. To prevent downstream maintain after injection, we assumed installation underground barrier at outlet model, following changes balance were simulated. level persistently maintained ~31-cm rise, 590 could be supplied from collector well, can ease shortages. Therefore, it necessary develop structures recharged escape when artificially recharging small basins. In areas where reservoirs or conduits are unfeasible, artificial systems solve
