There is an increasing requirement for information on the sediment transfer within the fluvial systems of catchment basins of different scales. Little is currently known about the residence times of sediment particles moving through the fluvial system. Such infonnation, for example, may be needed to provide a basis for establishing sediment control strategies, to afford an improved understanding of...
The investigation of suspended sediment size distribution (SSSD ) was carried on in a small agricultural watershed of Zagożdżonka river. The Low Angle Laser Light Scattering method w as used for SSSD determination. Received results has shown annual changeability in SSSD. The d50 characteristic diameter varied from 0.045 do 0.10 micrometer. The relationship between d50 and mean flow was described.
On the basis of eight recorded rainfall-runoff-suspended sediment events in a small, agricultural catchment of the Zagożdżonka river, a ratio of runoff lag time (Lag) and lag time of sediment flow (Lags) was analysed. The first Lag time of them is defined as the elapsed time between the occurrence of centroid of eflective rainfall and the storm runoff hydrographs. The last one is defined as the elapsed...
The main areas on water structures in which sediment gathers are headwater, hollows in construction and tailwater. The processes of accumulation of upstream and downstream positions develop according to duration of the object’s exploitation. This article analyses working conditions of an elongated pipeline of culvert in Potok Służewiecki stream. These conditions were examined with the aim to evaluate...
Zabudowa dolin rzecznych ciągami komunikacyjnymi i towarzyszącymi im budowlami prowadzi do podziału i ograniczenia siedlisk zwierząt dziko żyjących. Utrudniają również migrację gatunków wędrownych i organizmów przemieszczających się z wodami cieku. Zadaniem budowli wodnych jest utrzymanie spadku podłużnego cieku, zabezpieczenie koryta przed erozją oraz transport rumowiska rzecznego przez przekrój...
W artykule przedstawiono przegląd dotychczasowych badań na świecie i w Polsce w zakresie wykorzystania sztucznie tworzonych mokradeł (constructed wetlands) do ograniczenia ilości materiału stałego w odpływie rzecznym, pochodzącego z erozji gleb w zlewni. Systemy hydrofitowe są od ponad 30 lat szeroko stosowane do usuwania zanieczyszczeń zarówno ze źródeł punktowych jak i obszarowych. Większość publikowanych...
