| Description | Paper is dealing with monitoring of riparian forest and large wood in the channel and floodplain of the River Dyje in the river reach between the dams of water reservoirs Vranov and Znojmo. The repeated input of large quantities of wood by floods to water reservoir Znojmo occurs. The uprooting and breakage of riparian trees and their input into floodplain and river channel were monitored in 36 reaches of the river corridor, each 200 m long. Furthermore, the input and output of large wood by floods were monitored in the river reaches. Trees and large wood were marked by metal tags and localized by GPS. In the same time the large wood floated to the dam of the Znojmo water reservoirs was documented. The budget of large wood in the studied river reaches were elaborated (input, output, transport). The budgeting is a part of the evaluation of the threat caused by blocking the spill of the dam by floated wood. |
