In Kamienna River Valley the iron ore exploitation was done for a very long time. The intensification of the mining took place in XVIII and XIX century. For this region played an important role Stanisław Staszic. Kamienna River was supposed to be the source of energy and way of transport. Therefore, the river canalization and intensive training was undertaken, in consequence the river course was straighten and shorten, which resulted in the significant change in the river dynamics. Meander elimination and introduction of a uniform cross-section resulted in deterioration of habitat. To-day Kamienna River has deeply incised bed, which causes the drainage of surrounding grounds. After the analysis of the old maps and the river cross-sections it was found that it is impossible to restore the old river bed, because of the important erosion and cut off the sediment transport by dams on Świślina and Kamienna Rivers. Moreover the canalized river along some industrial vestiges is a part of technical patrimony. Therefore the only slight improvements could be proposed – introduction of slight meanders, more natural bed form and irregular banks. That could be obtained by an introduction of small hydraulic structures diverting the water stream. ...
