Abstract: Nonlinear optimization models are developed to design and manage furrow and border irrigation methods. The objective function of the basic nonlinear model is constructed on the basis of a profit relationship, while that ...

Abstract: A linear optimization model for planning the management of Irrigation District No. 38, in the State of Sonora, Mexico, is presented. The model considers the yield, price, and production cost of twelve primary crops; the ...

Abstract: A procedure to select an optimum irrigation method for specified field conditions is presented. The procedure is developed on the basis of indices that show the acceptability of the irrigation methods to the selection ...

Abstract: This paper presents furrow and border irrigation design optimization models for corn. The models, which have nonlinear objective functions and constraints, are linearized to take advantage of existing linear programming ...

Abstract: This paper develops a nonlinear optimization model for the design and management of drip irrigation systems. Decision variables are: pipe diameter, pipe length, number of emitters in each lateral, number of laterals in a ...

Abstract: A simulation model is presented for planning the conjunctive use of irrigation water from a single multipurpose reservoir and an aquifer, and the allocation of cropped areas within an irrigation district. The model considers ...

Abstract: Several methods for measuring the rate of infiltration in a volcanic ash soil are compared on the basis of field measurements. Methods that use stagnant water give lower values of soil infiltration rate than those that use ...
