A review of the major drawbacks of currently available surface irrigation mathematical models has been made and a course of action to alleviate these problems is suggested. The individual elements which constitute a complete set of dependent irrigation parameters in surface irrigation systems design and management have been defined and methodology for the development of explicit prediction functions is proposed. It has been illustrated how knowledge from diverse disciplines, such as modelling of surface irrigation process, dimensional analysis, experimental design and regression analysis, can be pulled together to arrive at a meaningful set of simple design and management equations. The potential use of these equations, which include such areas as optimal system design and automatic feed back control, have also been discussed.

(Location: IWMI-HQ Call no: PER Record No: H013383)
There exist capabilities for analyzing the behavior of surface flow and the ultimate distribution of infiltrated water in furrow irrigation. The corresponding synthesis, i.e., the selection of appropriate combinations of inflow rates, cutoff times and length of furrow - design and management, currently not so well established, is treated herein. A design-management nomograph is proposed for free draining graded furrows. This is a plot of efficiency, time of cutoff and uniformity coefficient contours each given on a length-flow rate space adjacent to one another, for a furrow with given infiltration characteristics, flow geometry, slope, roughness and required depth of application. The nomograph can be used to determine the combinations of length, time of cutoff and flow rate that would yield in optimum combination of efficiency and uniformity.

The hybrid model has been evaluated in terms of sensitivity to its parameters as well as prediction accuracy for advance and recession patterns. The sensitivity analysis results have revealed that the model solution parameters are insensitive, whereas the soil and crop parameters are sensitive. The advance and recession patterns are simulated satisfactorily by the model. The model has potential for use in the design and management of dyked and sloping borders.

This paper discusses the importance of integrating optimization and simulation. A hierarchical approach is presented which involves three levels; aggregate optimization and built-in simulation, disaggregate optimization, and detailed simulation. The paper also presents the application of the approach to strategic water resources allocation for a real-life problem.

(Location: IWMI-HQ Call no: PER Record No: H014410)
A downstream control algorithm for on-demand operation of irrigation canal system is presented. A constant water level is maintained at the downstream end of the pool. The approach is based on an explicit finite-difference solution procedure of the St. Venant equations. The upstream gate settings are corrected according to the water level and the flow rate at the information nodes along the canal. The method is illustrated for the control of a canal pool bounded by an upstream gate and a downstream gate or pump. The effectiveness of the control has been tested using an unsteady-flow simulation model that is based on the complete St. Venant equations and the implicit Preissmann scheme. The simulation results show that the proposed control method can cope with rapid variations of water demand and unknown disturbances in the system. The influence of the number of information nodes and assessment of the physical parameters of the system on the response of the system has been investigated. Unless the estimated physical parameters of the system are too far from their actual values, an effective control can be achieved by measuring the water level and estimating the flow rate only at the most upstream and downstream ends of the pool.
