Open publisher page 3 citations

Abstract

In South Africa, the demand for water exceeds available supplies in many catchment areas. As a result, farmers face increasing pressure to use water more effectively, to justify existing water requirements and to budget and plan with growing uncertainty regarding water availability. Therefore, a tool to manage and assess catchment water supply and demand interactions and the associated impacts on the profitability of irrigated sugarcane would be of great value. In this communication the development of such a catchment scale irrigation systems modelling tool is described. The model has application for testing and assessing various operating, water allocation, water management and water resources development strategies. The tool is also designed to predict the expected performance of different types of irrigation system hardware.
