Regulation of mountain streams versus ecological balance as illustrated by the example of the upper Vistula basin (part I)

Streams of the Polish Carpathians are characterized by a high gradient as well as a great changeability of their volume and velocity of flow. The processes which take place in these streams are those connected with lateral, bottom and channel erosion. In order to reduce those types of erosion, vario...
