TOPOGRAPHICAL TECHNIQUES APPLIED IN THE CRISUL ALB BASIN AS THE BASIS OF COMPLEX HYDROLOGICAL STUDIES

Abstract

The Cri?ul-Alb River springs from the Apuseni mountains, and its course crosses many rural and urban towns. In the Cri?ul Alb hollow, there are several tributaries that have a significant contribution to the volume and water flow of the Cri?ul Alb River. Due to the abundant precipitation combined with the melting of the snow during the spring period, high levels of water flow are created, endangering human settlements and other goods isolated by their flooding. The aim of the paper was to present a topographic study that would be the basis for the subsequent preparation of a complex hydrological study. This is the basis of a project to repair the breach as a result of the rupture of the body of the dam, following the high levels of flowing water. By optimizing the flow at high flows, the color of the flow is created through measures to reduce the roughness, to highlight the active erosions from the banks, in the minor bed or in the major bed of the Cri?ul Alb River. The paper also presents the method of carrying out some topographical measurements in the bed of the Cri?ul Alb River, in the area located north of the town of ?ipari, between the CSA terminals with numbers 5 and 43, and the processing of the respective measurements in order to draw up transversal profiles through the bed and a longitudinal profile on the respective portion.
