The costs of water retention in landscape and wetland creation in Czech republic.
ČERNÝ, Jan
Different types of man-made retention systems (polder, small water reservoir, large water reservoir) have been characterized by means of their retention potential and cost of retention per one cubic meter. As part of these man-made retention systems, wetland area has been created. Its acreage and build expense has been counted up inreference to total area, which differed within various types of retention systems. The results of these calculations, Hessenian method, and the metohod of agricultural land use were used to evaluate natural river basin and its retention potential. The calculations reveal, that model locality of natural river basin has the lowest value, when used for agriculture cultivation. Hessenian method showed the highest value. The expense of substituting the natural retention of the model locality with different man-made retention systems is estimated to be 0.5?1.6 billion CZK.
