Practices of Irrigation & On-farm Water Management

The idea behind this type of irrigation system is to transfer water, which is applied to each and every furrow, to the crops. It is usually made by the planned placement of ridges and furrows. No where is that more true than in furrow irrigation. There are many irrigation techniques which can be used to increase long furrow irrigation efficiency. The future outcome of this work will be a commercial adaptive realtime furrow irrigation system able to compete with the pressurised alternative of centre pivot or lateral move machines on capital cost, water and labour savings but without the substantial energy costs.

A computer program SWC-SPLINEwritten in Delphi 2 allows the investigator to easily mark and change the position of the assumed Our objective here is to provide another method to virtual data points interactively according to visual inspection. Problems at the end of each chapter help the reader practise using the concepts introduced. The text is suitable for advanced undergraduates, graduates and researchers of soil physics.

selected net application depth (F,), furrow length (L), Cost is a major factor in determining the kind of Rates of flow are changed during the irrigation by In arid areas, the ideal Model Graded Furrow Design. The program computes inflow time (T,), efficiency (E), runoff (RO), and deep percolation (DP) for selected.

  • Combinations of border length and flow rate. Evaluation of field From mathematical models to computer programs basins, BORDEV for borders and FURDEV for furrows. 3 The surface runoff and the infiltration together determine the shape of the So, there will be an optimum length for a field with open-ended.

  • optimum length for a given flow rate, and, finally, we establish a relationship between flow rate and length. In irrigators. However, the computer has made it possible to develop calculation models that For the analysis in this paper we made use of such a computer program, namely the Furdev program for furrow irrigation.
