Assessment of runoff within an experimental and representative hydrographical basin (Sebeș, România) [articol]

Abstract

The hydrographical basin of the Sebeș River is situated in the west part of Romania, it has a small surface (124 km2) and which is part of E.R.B. – European Network of Experimental and Representative Basins. The role of hydrographical experimental basins is to understand and to know the process of runoff formation into a small catchment (surface < 150 km2), especially that in the context of climate change the small hydrographical basins will be affected first. It is important to understand which is the impact of the climate change on runoff from a small basin because even a small decrease of water discharge regime will increase the risk of water level falling below ecologically or economically required minimum flows or even of rivers drying up. This study focused on assessment of runoff from a long period of time (1964-2013) in a small hydrographical basin, an important step in the impact evaluation process of the different types of runoff (mean, maximum and minimum) on the surface of the small hydrographical basins within Banat hydrographical space.
