“…However, it has been shown for several floodplains that the water quality is not homogeneous across the floodplain. Distinct spatial patterns in inundation water quality have been observed for temperate river floodplains in Poland (Chormanski et al 2011;Keizer et al 2014) and Austria . Large river floodplains located from the Arctic to the Amazon also demonstrate a zone of mixing between the sediment-rich river water and the local water (groundwater and/or precipitation), defined as the Bperirheic zone^ (Mertes 1997).…”

“…The hydrology and ecosystem function of floodplains are highly dynamic (Junk et al 1989;Bayley 1995;Ward et al 1999;Ward and Tockner 2001). The extent, depth, and duration of inundation depend on the hydrology and local topography (Steiger and Gurnell 2003;Southwell and Thoms 2011;Langhans et al 2013), while the chemistry of floodplain water is a function of exchange processes between groundwater and surface water and the influence of precipitation (Boulton et al 1998;Doering et al 2013;Keizer et al 2014). Nutrient transport in the river-floodplain system is important for the productivity and species richness of floodplain vegetation.…”

Flood Water Hydrochemistry Patterns Suggest Floodplain Sink Function for Dissolved Solids from the Songkhram Monsoon River (Thailand)

Although important for the eco-hydrological functioning of the floodplain, the interactions between river and floodplain are not well understood, especially for rivers in the tropical monsoon region. To explore the floodplain functioning of a tropical monsoon river system the longitudinal and transverse floodwater hydrochemical characteristics were studied in the Songkhram river (Thailand) and its floodplains. Water samples were taken during the monsoon period from 61 locations in the river and on its floodplain. Analysis of floodwater hydrochemistry revealed a significant decreasing longitudinal trend for most dissolved solids, attributable to geological differences. We also observed a significant decreasing transverse trend from river to floodplain. Nutrient concentrations revealed lower dissolved nitrogen, phosphate, and potassium concentrations on the floodplain than in the river channel, which suggests the floodplain functions as a sink for nutrients and chemical species in the river floodwater. This sink function may be related to the presence of a belt of bamboo separating the river from the floodplain, which seems to acts as a sediment trap and nutrient filter, but this needs to be verified by additional dedicated research.

“…Among those dominating over the area, Caricetum gracilis (Carex) shrubs were found with a considerable share of Glyceria maxima, Rorippa amphibia, and Iris pseudacorus. Particular habitat conditions for the above-mentioned species involve river valleys and shallow lake basins with the dominance of mineral-organic deposits, and ground water levels near land surface [14]. Nearly permanent flooding is their permanent feature; thus, they are often named riverside carrs.…”

“…Nearly permanent flooding is their permanent feature; thus, they are often named riverside carrs. On the other hand, numerous Molinia meadows appeared within the study site, attributable to peat-mineral or marsh soils, characterized by variable water content and ground water depth of 0 to 1.5 m, which makes them permanently or periodically wet or moist [8,14,15].…”

Ground Water Modelling for the Restoration of Carex Communities on a Sandy River Terrace

et al. 2016

Management for sustainable river valleys requires balancing their natural values against the need for agricultural and recreational development on surrounding lands. The Southern Całowanie Peatland near the city of Warsaw sits on a sandy terrace and has well preserved Carex and Molinia stands existing in part of the area, especially where water tables are less than 1.5 m below the surface. The existing drainage network in this southern part has been poorly maintained and could be reestablished to help raise water levels for restoration of the peatland. Modflow was used to look at influence of drainage channel water levels on the overall water table height in the area. By raising water levels in the drainage system by 0.5 m it was found that 29% of the area would become suitable for increasing Carex and Molinia communities.

Abstract. Airborne laser scanning survey data were conducted with a scanning density of 4 points∕m 2 to accurately map the surface of a unique central European complex of wetlands: the lower Biebrza River valley (Poland). A method to correct a degrading effect of vegetation (so-called "vegetation effect") on digital terrain models (DTMs) was applied utilizing remotely sensed images, real-time kinematic global positioning system elevation measurements, topographical surveys, and vegetation height measurements. Geographic object-based image analysis (GEOBIA) was performed to map vegetation within the study area that was used as categories from which vegetation height information was derived for the DTM correction.
