A NEW INNOVATIVE DECISION SUPPORT SYSTEM USING FUZZY REASONING FOR THE ESTIMATION OF MOUNTAINOUS WATERSHEDS TORRENTIAL RISK (TOR-SYS). THE CASE OF RIVER KOSYNTHOS

摘要

This research effort describes the design, development and testing of a Decision support system that performs torrential risk estimation of mountainous watersheds. The system applies an innovative model of Fuzzy logic. The application of the system was done in one of the most risky watersheds of Greece river "Kosynthos" which is located in the North-Eastern part of the country. The system was tested successfully in the 32 most important subwatersheds of "Kosynthos". Its main advantage is that it offers the chance to evaluate the torrential risk of the mountainous watersheds based on a small number of parameters that are easy to measure. The final target is the classification of the watersheds based on their risk.
