THE WATER BALANCE’S IMPACT OF THE DEAD SEA’S TRIBUTARIES ON THE DEVELOPMENT OF ITS PORT WATERS
Journal Title: Present Environment and Sustainable Development - Year 2010, Vol 4, Issue 4
Abstract
The tendency of change of the hydrological parameters of the Dead Sea is increasingly evident in recent decades, both as a consequence of high evapotranspiration and as a reduction in volume of Jordan’s waters and of other tributaries. Basically, this is manifested by the lower sea level, which may result even in its death in a near future. Intense evapo-transpiration (average 1500 mm / year) leaded in time to lower water level, which changed the aspect of port waters as well as the emergence of underground cavities as a result of salt dissolution. The same effect it has the excessive use of Jordan for potable water for the growing population, as well as for industrial water or irrigation, by Israel and Jordan. The reduction of water balance of the sea is reflected in increased regressive erosion on tributaries, with effect on disposition of watershed around the sea, but in the Jordan basin, as well. As a result, the target of our study was focused on the revaluation of the rate of decline in volume and sea water level by extending the range of hydrological observations. The current quantifying is an alarm on the decreasing flow of Jordan river, the negative balance of the level of port waters of Dead Sea, with immediate consequences on the region's sustainable development.
