摘要: Abstract Irrigation projects in developing countries have a history of poor performance. Inefficiencies result as water applications deviate from plans and induce greater than projected rates soil degradation through logging salt accumulation. Over time, the collective impact these forces will converge to an equilibrium with level output that may be far below system’s potential. The Tungabhadra Project south west India is experiencing all problems. Integrating geographic, hydrologic, biologic economic features, lost production value estimated for range equilibria which this system converge. For lower left bank main canal project, total cost are approximately 14.5% productive potential while sub-optimal distribution losses approach 37.1%.
