This projects aims at a solution for problems related, on the one hand, to water distribution during dry periods in Flemish navigable waterways and, on the other hand, to water depletion phenomena in the valleys.The first stage of the project produces a survey of all area-related water fluxes, issues and actors. Collected data are processed to compute a water balance to identify all problem-areas in the Flemish region.In a second stage the different associated actors (navigation, industry, agriculture, fishing, drinking-water supply, recreation, nature and different involved administrations) are being involved through interviews and a workshop.In a third stage a program of measures (e.g. reduction of water intakes by industry, nature & agriculture, …) is being worked out by using numerical models and cost-/benefit analysis for each waterway. This program is meant for effect-oriented implementation during shortage periods.Beside this, the goal of this project is to apply as many source-oriented measures as possible in order to decrease the occurrence of low flows and drought.
