“…Finally, human alteration of fluvial geomorphology (e.g., dams, historic mill dams, channelization, and grade control structures) and changes in land use can also affect sediment sources, transport, and sinks in watersheds (Hupp and Simon ; Walter and Merritts ; Pizzuto and O'Neal ; Donovan et al. ). These changes in sediment sources and hydrologic connectivity could also impact rates of sediment and nutrient inputs to floodplains, which in turn can influence internal biogeochemical transformations in floodplain soils (Richardson et al.…”

“…The lateral geomorphic units of floodplains (e.g., levee, backswamp), and corresponding topographic variation, also generate spatial variation in floodplain processes from channel to edge of floodplain (Hupp and Osterkamp 1985;Noe et al 2013a;Pizzuto et al 2016). Finally, human alteration of fluvial geomorphology (e.g., dams, historic mill dams, channelization, and grade control structures) and changes in land use can also affect sediment sources, transport, and sinks in watersheds (Hupp and Simon 1991;Walter and Merritts 2008;Pizzuto and O'Neal 2009;Donovan et al 2016). These changes in sediment sources and hydrologic connectivity could also impact rates of sediment and nutrient inputs to floodplains, which in turn can influence internal biogeochemical transformations in floodplain soils (Richardson et al 2004;Jordan et al 2011;Noe et al 2013a).…”

Floodplains and streambanks can positively and negatively influence downstream water quality through interacting geomorphic and biogeochemical processes. Few studies have measured those processes in agricultural watersheds. We measured inputs (floodplain sedimentation and dissolved inorganic loading), cycling (floodplain soil nitrogen [N] and phosphorus [P] mineralization), and losses (bank erosion) of sediment, N, and P longitudinally in stream reaches of Smith Creek, an agricultural watershed in the Valley and Ridge physiographic province. All study reaches were net depositional (floodplain deposition > bank erosion), had high N and P sedimentation and loading rates to the floodplain, high soil concentrations of N and P, and high rates of floodplain soil N and P mineralization. High sediment, N, and P inputs to floodplains are attributed to agricultural activity in the region. Rates of P mineralization were much greater than those measured in other studies of nontidal floodplains that used the same method. Floodplain connectivity and sediment deposition decreased longitudinally, contrary to patterns in most watersheds. The net trapping function of Smith Creek floodplains indicates a benefit to water quality. Further research is needed to determine if future decreases in floodplain deposition, continued bank erosion, and the potential for nitrate leaching from nutrient‐enriched floodplain soils could pose a long‐term source of sediment and nutrients to downstream rivers.

“…Such studies improve models predicting where and when migration will occur, providing useful information for environmental management, protection of infrastructure, and stream restoration. Remotely sensed imagery is commonly used to measure changes in river planform in response to changes in land use, urbanization, deforestation, and dam building or removal (Constantine et al., 2014; Donovan et al., 2015, 2016; Gurnell et al., 1994; Gaeuman et al., 2005; Hickin & Nanson, 1984; Lauer & Parker, 2008; Morais et al., 2016).…”

“…Studies of this scope have not been carried out previously for the catchment area located in this part of Poland and Europe. However, bottom sediments related to the functioning of water mills were analyzed by other researchers in the context of the role of mill dam in regional erosion and sedimentation [33]. Also, along the middle course of the Havel, sedimentary sequences available for geoarchaeological and paleoecological research were analyzed in order to reconstruct regional water level dynamics [34].…”

The article presents the changes in a hydrographic network resulting from the construction and functioning of nine water mills located in the Struga Rychnowska catchment (Poland). Two ponds (Bierzgieł and Oleszek) have been chosen for a detailed study—both with similar basin origins and morphological settings, but different morphometries, paths of water delivery and discharges from the mill, and water retention times. An attempt was made to restore the course of the deposit sedimentation process in mill pond basins on the basis of historical sources, archived cartographic materials, fieldwork, and laboratory analyses (sedimentology, palynology, and 14C dating). The studies allowed determining the scope of anthropogenic impact on the environment on the example of small river catchment, both when the ponds were in use, and afterwards. Decommissioning of water mills induced a number of serious changes in water resources. The most important of them include: the loss of water retention capacity in the Struga Rychnowska catchment, and decreased ground water level in immediate vicinity of former water reservoirs. Currently, a renewed interest in the old locations of water mills is present, in order to restore retention, and use them for the purposes of modern small hydropower plants (SHP).
