The Water Sector for the CARD/RCA 85 Model
为CARD/RAC85规划模型构建农业水部门，以应对美国西部农业用水短缺及1977年水土资源保护法案对用水与保护的关注。
Availability of water for agricultural use is one of the major factors determining agricultural production in the Western United States and is becoming an important factor in areas of the Southwest. In addition, water use and conservation is an important concern of the 1977 Soil and Water Resources Conservation Act. Thus, it is necessary to build an agricultural water sector for use in the CARD/RAC85 programming models.
