Abstract:

An accurate estimation of peak flood flows and its correlation with existing and future land use are basic requirements for the scientific management of Watersheds. An accurate estimation of peak flood flows, however, is a difficult problem in a developing country, such as Trinidad and Tobago, where hydrologic data, especially streamflows, are often either non-existent or are of a very short duration. In such situations the use of Multiple Level Hydrologic Analysis provides a methodology for considerably increasing the accuracy of peak flood flow estimates. The paper describes the application of this methodology to the Cunupia River Watershed in Trinidad and explains, how the greater accuracy of estimates obtained contributed to the improved land use planning.
