This study assesses the water availability and the water scarcity based on the hydrologic behavior under different weather conditions and crop coverages in an irrigated agricultural area of Rincon Valley in New Mexico using the SWAT (Soil and Water Assessment Tool) model. Two spatial crop coverages included normal (2008) and dry (2011) years with 14 different crop sets for each year. The SWAT was applied to generate the five essential indicators (surface flow, evapotranspiration, soil water, groundwater recharge, and irrigation water) to evaluate the integrated water availability based on hydrologic response units (HRUs) along with the Arrey Canal to supply irrigation water in the crop areas. The water availability index scores (0–1 range with 1 being the most available and 0 the least available) of alfalfa, corn, cotton, and pecans were 0.21, 0.56, 0.91, and 0.20, respectively, in the normal year and 0.16, 0.78, 0.88, and 0.24, respectively, in the dry year. In the dry year, water scarcity values were high in mostly alfalfa areas, whereas cotton areas have mostly no stress with good water availability. The major water users of crops, ranked in order, were alfalfa, pecans, cotton, and corn. During the dry year, water availability showed to be balanced in terms of water supply and demand by controlling crop patterns from reducing alfalfa acreage by 12% and increasing cotton acreage by 13%.

基于SWAT的农业灌溉流域基于水文分量的水资源短缺与短缺评价。

这项研究使用SWAT（土壤和水评估工具）模型，基于新墨西哥州林孔谷（Rincon Valley）灌溉农业区在不同天气条件和作物覆盖率下的水文行为，评估了水的可利用性和缺水情况。两个空间作物覆盖范围包括正常年（2008年）和干旱年（2011年），每年有14种不同的作物。应用SWAT生成五个基本指标（地表流量，蒸散量，土壤水，地下水补给和灌溉水），以评估基于水文响应单位（HRU）的综合水利用量，并利用Arrey运河向该处供应灌溉水。庄稼地。苜蓿，玉米，棉花和山核桃的水利用率指数得分（0-1范围，最大的是1，最小的是0）是0.21，0。正常年份分别为56、0.91和0.20，而干燥年份分别为0.16、0.78、0.88和0.24。在干旱的一年中，大部分苜蓿地区的缺水率都很高，而棉花地区大部分都没有压力，且水资源充足。作物的主要用水户依次为苜蓿，山核桃，棉花和玉米。在干旱的一年中，通过控制苜蓿种植面积（减少苜蓿种植面积12％和增加棉花种植面积13％），在水资源供需之间取得了平衡。排名依次为苜蓿，山核桃，棉花和玉米。在干旱的一年中，通过控制苜蓿种植面积（减少苜蓿种植面积12％和增加棉花种植面积13％），在水资源供需之间取得了平衡。排名依次为苜蓿，山核桃，棉花和玉米。在干旱的一年中，通过控制苜蓿种植面积（减少苜蓿种植面积12％和增加棉花种植面积13％），在水资源供需之间取得了平衡。
