DETERMINATION OF THE SOIL EROSION IN THE HYDROGRAPHIC BASIN OF HOMORICIU VALLEY BASED ON THE MAXIMUM DRAINAGE FLOW
Abstract
The analysis of the solid torrential flow in the Homoriciu river basin was done between the period 1970-2018 depending on the climatic data and the location of the studied area . The study of the morphohydrodynamic phenomena evolution in the studied area was also based on the comparative analysis This research work focuses on the complex phenomena of drainage liquid and solid production, the flow rates of rising and spreading of rain formation in the studied basin. of the longitudinal and transversal profiles of the 1970s and 2018s. The main cause of producing the instability of the slope in hydrographic basin of the Homoriciu Valley is represented by the erosion thalweg and banks phenomenon , especially the left bank in the flow direction. The surface erosion of the land in the hydrographic basin determines the amount of alluvial capacity produced by the dispersed effluent represented by the specific erosion that is turned into real erosion through the effluent coefficients. Wischmeier, Motoc M. and Stanescu P., have developed the universal soil loss equation destinated for Romania conditions, establishing the value of the parameters for different climatic conditions, relief, soil, crops and means of soil erosion control, based on the researches made on runoff plots for a long period. In order to determine the evolution of the Homoriciu valley thalweg, the longitudinal profile elaborated by ISPIF Bucharest in 1970 was taken as a basic element, which was compared with the topographic elevation of the erosion formation in the depth of 2018. The estimation of the surface erosion on agricultural land in Homoriciu river basin was calculated according to the Maracine Nicolae method for each runoff plots, delineated on the study plan of the hydrographic basin of the erosion formation. The fluvial erosion calculation was made for the maximum flowrate, which is formed on the base of a torrential formation of the Homoriciu Valley, according to the method developed by Maracine Nicolae, as well.
