Efficiency of soil and flood control measures in land consolidations

Abstract

Land consolidations are an important instrument for implementation of erosion and flood control measures. Thanks to their poly-functional character, they also contribute to increase of ecological stability and aesthetic of landscape. Although the land consolidation process does not advance as quickly as requisite, it brings unquestionably positive results. One or more erosion and flood control measures are built in 17 % of cadastres with finished complex land consolidation. Land consolidation designs are supported by the state and the EU funds are used for the realization of protective and ecological measures. With the aim to evaluate real efficiency of implemented measures, research project QI92A012 has been started. This paper presents its method principles and particular results for one of the model cadastres - Lejčkov. Realized elements in Lejčkov were confronted with the plan of common facilities and critical analysis of the size, parameters, type and localization of elements was made with regard to their efficiency to keep the soil from surface erosion away in the long run, to decrease discharges and sediment transport in extreme precipitation events. We can state that erosion control measures in Lejčkov were designed and built well and they are suitable for the highland type of countryside.
