Assessing agriculture conservation practice impacts on groundwater levels at watershed scale

摘要: Over the last several decades, increased groundwater usage by agriculture with a consequence of resource depletion has motivated discussion sustainability resource. In this study, to investigate impacts agricultural best management practices (BMPs) on level, two kinds conservation and five scenarios tail water recovery pond crop rotation were simulated various recharge pumping plans in Soil Water Assessment Tool (SWAT) MODFLOW models an watershed Mississippi, U.S.. The calibrated validated ground model indicated coefficient determination (R2) 0.81 Nash–Sutcliffe efficiency (NSE) 0.79 respectively. results from study showed that changed irrigation surface hydrological impact practices. addition, it determined could help mitigate depletion. due continuous corn scenario was 7% higher average than soybean. Non-growing season may be critical for recovery. level 15%, soybean 13%, corn-soybean 14% as compare baseline rice planted. Results can helpful planning how BMPs groundwater.
