Abstract:

In this diploma thesis, it is estimated the failure of a variable’s geometry part of the soil and the erosion of the river bank due to the water flow. This assessment is carried out using the Bank Stability and Toe Erosion Model (BSTEM) in the Kiliaris River basin, in particular, in Mantamas area. For this purpose, field measurements were performed at selected points. Data processing of the measurements showed the presence of erosion of the riparian zone of the Kiliaris river, as well as instability of the slopes.

Specifically, during the elaboration of the study a study of the wider river area was carried out in order to determine its physical functioning and all the watercourses that contribute to it. Soil sample was taken and laboratory analysis was carried out in order to find the species and its properties. Sampling points are signs of intense erosion. The plant cover of the area was initially recorded empirically and then the species of each plant was identified through the literature review. Also, topographic mapping of the area was made. In particular, there were found the coordinates at various points, so that the profile of the bank could be visualized. In particular, the data on the eroded part of the river was the input data of the BSTEM program. In the Surfer program (15), the coordinates of the entire study section were input, resulting in three-dimensional imprinting.

Finally, measures are being taken to rehabilitate and protect the Kiliaris riparian forest. Rehabilitation measures are proposed with a focus on their applicability in the study area, their cost, their lifetime and their risk of failure.
