Abstract

The study presented demonstrates the use of the entropy concept, as defined in information theory, to assess the regional uncertainty and indirectly the regional information available about floods. The method is used to describe the total uncertainty related to floods in a basin, together with the joint information provided by observed data of existing streamflow gages. The contribution of each gage to this total information is assessed eventually to arrive at a better combination of stations in transferring flood information from one space point to another. This is realized by a priority listing of stations in order of their contribution to the decrease in regional uncertainty. The application of the method is demonstrated in the case of a Turkish river basin, where coping with floods is a major problem. The strengths and shortcomings of the method are discussed, with recommendations for future research on the application of the entropy principle in evaluating regional transfer of information about floods.
