Hydrological Model Keta Lagoon Basin, Ghana (Including Appendix)

摘要

The aim of the hydrological research is to acquire a good insight into incomingand outgoing water quantities of the Avu-Keta lagoon area, by means of drawing up a water balance, essential to the inception of strategies for the solution of the flood problems. By knowing the cause and the process of the flooding exactly, by means of drawing up a water balance, more solutions for the flood problems can be found, instead of only an expensive controlled outfall at Kedzi. The result of the research will be several alternative solutions for the flood problems so that in a later comprehensive study of the development of the area the best solution for the flood problem, in terms of costs and benefits, can be found. As a consequence of the study of the hdrological data a hydrological model of the area will be made. It might be used as a forecasting model so that the inhabitants of the area can be warned of the coming flood. In a later stage the effects of the solutions can be materialized in the cost-benefit analysis of the various solutions.
