The objective was to improve the estimates of the value of irrigation water. This information is essential to the development of efficient irrigation systems and groundwater management policies. The conventional method of evaluating the value of irrigation water (based on the agronomic production function) has lacked the desired level of precision. This study attempts to formulate an analytical model which incorporates various relationships associated with plant growth. The model has two major components: the soil water budget and the crop evapotranspiration function; and biological growth curves. Computer simulations were made to check the validity of the model and the estimated coefficients. (Author)
