van Rooijen, E.J. (author), Mosselman, E. (author), Sloff, C.J. (author), Uijttewaal, W.S.J. (author)Confluences are fascinating elements in river systems. The merging of tributary rivers produces complex hydrodynamics that can play an important role in sediment transport problems, ecological studies or the routing of a pollutant. If the two merging rivers originate from different regions they can have different characteristics. One such a...abstract 2017

Koopmans, H. (author), Huismans, Y (author), Uijttewaal, W.S.J. (author)Variable flows and fast morphological changes characterize the river system of Bangladesh, which includes the downstream reaches and delta of the Ganges and Brahmaputra rivers, two of the largest rivers in the world. In contrast, fresh water supply around the country largely depends on much smaller distributaries that take off from those large...abstract 2017

Weisscher, S.A.H. (author), Baar, A.W. (author), Uijttewaal, W.S.J. (author), Kleinhans, MG (author)Lateral sorting (= bend sorting) is observed in natural meanders, where the inner and outer bend are fairly fine and coarse, respectively (e.g. Julien and Anthony, 2002; Clayton and Pitlick, 2007). This is caused by the mass differences between grains on a transverse slope, leading to coarser grains being...abstract 2017

Duro, G. (author), Uijttewaal, W.S.J. (author), Kleinhans, M (author), Crosato, A. (author)Waterways serve for several functions besides transporting goods and people. The ecological importance of navigable rivers has taken much attention during recent decades bringing efforts to improve these natural corridors for fauna and flora (Boeters et al., 1997). Following the policy of the European Water...abstract 2017

Baar, A.W. (author), Weisscher, S.A.H. (author), Uijttewaal, W.S.J. (author), Kleinhans, MG (author)We experimentally tested the effect of a largerange in helical flow intensity and sedimentmobility on equilibrium transverse slopes,which resulted in a function for slope effectsdepending on bed state and sedimenttransport mode, that deviates from linearfunctions with sediment mobility in literature...abstract 2017

Le, T.B. (author), Crosato, A. (author), Uijttewaal, W.S.J. (author)Recently, engineers propose longitudinal training walls to replace traditional transverse groynes. This new intervention is expected to maintain a navigation route under low flow conditions while not hampering flow conveyance of the river channel. Navigation occurs mainly in low-land river channels where ...abstract 2017

Bonilla Porras, J.A. (author), Crosato, A. (author), Uijttewaal, W.S.J. (author)Although many studies regarding bank erosion and accretion can be found in the literature, it is not common to find works studying the interaction between opposite banks. Some existing morphodynamic models describe bank erosion as an event that depends on near-bank flow and bed topography, as well as on...abstract 2017

Tas, S.A.J. (author), Gijón Mancheño, A. (author), Herman, P.M.J. (author), Reniers, A.J.H.M. (author), Uijttewaal, W.S.J. (author), Winterwerp, J.C. (author)In this paper the typical hydrodynamics on mangrove-mud coasts are studied. Worldwide, these coasts experience serious erosion problems, and while the importance of mangrove ecosystems is becoming widely recognised, mangrove restoration projects frequently fail due to poor understanding of the system, especially the hydrodynamics. Therefore, a...abstract 2017

(author)During recent decades, mangrove forests have experienced severe degradation due to unsustainable land use. Restoration of mangrove ecosystems requires the recovery of their habitat, considering ecology, hydrology, hydrodynamics, and sediment transport. In a first pilot in 2013, brushwood dams were built on the eroding coast of Demak, Indonesia,...abstract 2017

Wetser, A. (author), Uijttewaal, W.S.J. (author), Mosselman, E. (author), Penning, E. (author), Duro, G. (author), Yuan, J. (author)Over the past centuries natural river banks have been transformed into banks with artificial revetments or sheet piles to protect them from erosion. Important river features for flora and fauna have disappeared and the ecological quality of the river reduced dramatically. Recently, the importance of the ecological function of rivers has been...abstract 2017

Jammers, S.M.M. (author), Paarlberg, AJ (author), Mosselman, E. (author), Uijttewaal, W.S.J. (author)Longitudinal training dams (LTDs) are constructed in the River Waal in the Netherlands. They are aligned parallel to the river shore and divide the river into a main and side channel. The existing groynes are removed yielding more discharge capacity at high flows. The side channel creates possibly a ...abstract 2017

(author)Plastic pollution is a threat for all ecosystems due to its effects on people, animals, and environment (Mai et al., 2020). Rivers are estimated to transport around 0.5 millions tons of plastic per year (Strokal et al., 2023). When plastic enters a river system, it is transported downstream towards the sea but it is also likely to accumulate at...abstract 2024
