2. SLM技术的说明
2.1 技术简介
技术定义:
Small wooden check dams built in erosion rills, grooves or gorges to reduce flood risk.
2.2 技术的详细说明
说明:
The terrain is considerably sloping with deep "V" cuts in steep terrain. In that area small check dems, made of wooden logs, were realized..
Purpose of the Technology: The aim was to reduce flood risk mitigation by torrential rains and local flooding.
Natural / human environment: The area is situated in a valley at the foot of the Carpathians, which are part of the outer Carpathian Belt formed by flysch. Relatively large differences in elevation of the country cause excessive concentration of surface runoff. Substantial part of the tributaries are formed by concentrating runoff in ravines, erosion grooves, rills. Most of the country consists of agricultural production of crops, less by forests and grasslands.
