In order to visualize the negative consequences of soil erosion processes running in Georgia, namely in the Gldaniskhevi ravine within the territory of Tbilisi, research field integrated polygon has been arranged on the eroded slope chosen beforehand.
At the control area of polygon 24 field experiments have been carried out to study the dynamics of the formed erosion processes under the different intensity precipitation conditions, whereby scour parameters were being measured (average depth – h, average width – b, B).
For estimating the exactness of calculations done on the results of measurings accomplished with the purpose to definite the intensity of soil erosion processes, the method of least squares have been used, on the base of which contour dependence between investigated parameters and therefore validity of the accomplished researches have been ascertained.
Simulative modeling of the soil erosion processes has been accomplished by means of special computer programs, which has shown, that during 167 days at the control area of the field polygon the eroded slope gulleying processes have been significantly strengthened, that nowadays can be also noticed on the slopes outside the polygon, on account of which can be concluded, that in order, to prevent expected landslide and debris flow phenomena in the river Gldaniskhevi ravine, implementation of urgent effective anti-erosive measures is needed.
