Stanovení ztráty půdy erozí a návrh protierozních opatření

In this diploma thesis I dealt with the water erosion of soil in the area of Libotovský potok. The basin was divided into eight erosively enclosed units. I have counted the average long-term loss of land without anti-erosive measures and with anti-erosive measures as well as the transportation of floodplains for both of these situations. The aim of this work was to evaluate the severity of water erosion and to propose anti-erosion measures by using the universal equation (USLE) and modified equations (MUSLE). According to the results of the universal equation, it was clear that there was a very strong erosion in the river basin. The total loss of the land was 12 419.88 tones per year. Therefore, both organisational (leaving post-harvest remnants) and agro-technical measures (curb contouring) were proposed there in order to reduce the values of Factors C and P. After that, the reduction in the loss of the has ended up on 2 628.93 tones per year. The final value of transportation of the floodplains without erosion measures was 30 671,77 tones. After changing the sowing technologies and the change in the values for the factors C and P, it decreased to 5 203,32 tones. The results of the diploma thesis show that the water erosion of the soil is a large and frequent problem of many agricultural lands, especially those where soil is left without any protective effect of vegetation and also where the broad-leaved crops are grown. An important factor that can significantly help to reduce erosion is also the right way of the soil cultivation
