The Government of Ecuador (GOE) invited the World Bank in 1975 for a general review of the rural development in the country. One of the main findings of a Bank mission was the importance of an adequate agricultural and rural development strategy for the fertile Lower Guayas Basin, frequently flooded and in need of drainage systems. The main project civil works would include a flood control system, consisting of bypass (flood-relief) channels, and construction/ improvement of river dikes. Modelling was used to design the most cost-effective and environmentally sound flood control system. Various basic alternatives for flood control have been identified and evaluated on the basis of technical, social and economic criteria. The project objectives and feasibility are discussed.
