Quantifying groundwater recharge beneath furrow irrigated corn using lysimetry, an unsaturated zone water balance and numerical modeling
Understanding the effects of new irrigation methods on groundwater recharge rates in semi-arid regions is becoming more important as the demand for water in these areas increases. Predicting groundwater recharge under furrow irrigated agricultural land can be a difficult task due to spatial variability of infiltration down a furrow, as well as the heterogeneity of hydraulic properties throughout the vadose zone. There are few methods currently being used to estimate the amount of recharge under these conditions. Each method has its own set of assumptions that create varying degrees of uncertainty ...
