DOWNSTREAM IMPACT OF THE GOLAN HEIGHTS RESERVOIRS, ON THE HYDROLOGICAL REGIME, STREAM MORPHOLOGY AND VEGETATION. (ISRAEL)

The study has started in 1985, in order to assess the impact of the Golan Heights dams upon the hydrological regime, river morphology and vegetation downstream. The results indicate that the reservoirs are the main dominant element, influencing the hydrological regime: the specific average peak discharge and the annual average water volume discharge in the impounded basin decreases by more than 50% and the recurrence interval time period increases the higher the peaks. Natural geo-indicators were identified; fresh water habitats near the reservoirs indicate instability and therefore are highly affected during extreme conditions such as drought or rainy years; the channel downstream from the reservoir shows a gradual alteration from a fresh water habitat into a swamp habitat.
