Rapid River Bed Recovery after the In-Channel Mining: The Case of Vistula River, Poland

The effects of in-channel wet-pit mining is nowadays widely discussed in terms negative influence the created pits on river ecosystem and fluvial processes. induce an alteration natural flow or sediment transport. This paper describes post-mining channel recovery observed a relatively short time gravelly sand bed lowland river. study was based repeated bathymetry grain size analyses material taken from area its surrounding upstream downstream pit. We also use calculations possible bedload movement studied reach. noticed that excavation pit exceeded maximum depth 8.8 m 2014 and, immediately after end mining, started to infill bathymetric measurements 2019 indicated process completed five years, though former refilled with finer than reach, consists mainly sand. infilling runs continuously, even during annual average water stages.
