Influence of Hydrologic Alteration on Sediment, Dissolved Load and Nutrient Downstream Transfer Continuity in a River: Example Lower Brda River Cascade Dams (Poland)
نویسندگان
چکیده
Hydrologic alternation of river systems is an essential factor human activity. Cascade-dammed waters are characterized by the disturbed outflow material from catchment. Changes in sediment, dissolved load and nutrient balance among base indicators water resource monitoring. This research was based on use hydrological quality data (1984–2017) Indicators Alteration (IHA) method to determine influence regime changes downstream transfer continuity sediments nutrients example Lower Brda cascade dams (Poland). Two types regimes were used: hydropeaking (1984–2000) run–of–river (2001–2017). Using IHA data, a qualitative quantitative relationship demonstrated between operation sediment balance. The sites above below made it possible load, trapping removing processes. Studies have shown that influenced supply chain transport cascade-dammed rivers. conducted showed sustainable management alternated catchment helps achieve good ecological status water.

Investigating the features and flow behavior and related component is one of the complex phenomena that make using of software inevitable. The rivers carry sediment content along with water which is created by erosion of riverbed sediment and erosion caused by rainfall or surface runoff flowing over the catchment area. If the action of river dewatering occurs, the entry of sediment into the int...
