COMPARATIVE STUDY OF THE FLOODS OCCURRED IN THE HYDROGRAPHICAL BASINS OF BISTRA M RULUI AND UCU RIVERS (2005 AND 2010)

Comparative study of the floods occurred in the hydrographical basins of Bistra M rului and ucu rivers (2005 and 2010). Bistra M rului and ucu rivers spring from arcu Mountains and are tributaries of the accumulation lake of Poiana M rului, being the main rivers transporting significant quantities of water to the lake. In order to perform an analysis from a morphometric point of view of the hydrographical network within the hydrographical basins of the two rivers, we have used the Horton - Strahler classification system, because, having a genetic basis, this classification system allows a comparative analysis of the hydrographical basins. By using this classification system, we have noticed that the two rivers have the same order and we have proved, what has already been known as a general rule, that the hydrographical basins with the same order, that are located in similar physical and geographical conditions, have on average approximately the same size of the reception basin surfaces, of the water flows, of the average slopes, of the course lengths etc. Moreover, we have proved that the two hydrographical basins have approximately the same shape and that the floods that they may generate are approximately identical as magnitude and manifestation.
