Return Flow Control Policy and Income Distribution among Irrigators
模拟了加州圣华金次流域不同水质政策对灌溉者收入分配和灌溉回流的影响，发现提高灌溉效率的政策改善了收入分配但平均收入略降，而提高地表水成本的政策则恶化了收入分配并大幅降低平均收入。
Abstract Income distributional impacts and irrigation return flows resulting from the implementation of alternative water quality policies were projected for the Western San Joaquin Subbasin from a recursive simulation of an integrated physical‐economic analytical system. The imposition of a water management policy to increase irrigation efficiency resulted in an improved income distribution with a slight decline in average firm income. Salt load and concentrations were reduced by 80%. A policy of increased surface water costs worsened income distribution and decreased average firm income by 34%. Total salt load decreased by 35%, but the concentration in return flows was only slightly decreased.
