Crosato, A. (author), Mosselman, E. (author)River training and river restoration often imply modifying the patterns and dimensions of bars, channels, and pools. Research since the 1980s has greatly advanced and matured our knowledge on the formation and behavior of river bars, thanks to field work, laboratory experiments, theoretical analyses, and numerical modelling by several research...review 2020

Cordier, Florian (author), Tassi, Pablo (author), Claude, Nicolas (author), Crosato, A. (author), Rodrigues, Stéphane (author), Pham Van Bang, Damien (author)Bars are large sediment deposits alternating with deeper areas that arise from alluvial river bed instability and forcing. The present study aimed at investigating the combined influence of flow and longitudinal width variations on the co-evolution between bar pattern and sediment sorting in a sandy-gravel river reach. To this goal, a fully...journal article 2020

Le, T.B. (author), Crosato, A. (author), Montes Arboleda, A. (author)The Dutch River Waal, a branch of the Rhine, has been trained for centuries to mitigate the effects of ice-jams and improve navigation. The works, started in 1850, involved river straightening and narrowing by a series of transverse groynes. Besides fulfilling their goal, the groynes also created the need to raise flood protection works and...journal article 2020

Mulatu, C.A. (author), Crosato, A. (author), Langendoen, Eddy J. (author), Moges, Michael M. (author), McClain, M.E. (author)This work investigates the applicability of an analytical method for quick assessments of the long-term morphological effects of different dam operations on downstream river reaches with the idea to apply the method in feasibility studies to identify the least morphologic-impacting operation scenario. The Ribb River (Ethiopia) is used as a...journal article 2020

Duro, G. (author), Crosato, A. (author), Kleinhans, M. G. (author), Roelvink, D. (author), Uijttewaal, W.S.J. (author)Vessel-induced waves affect the morphology and ecology of banks and shorelines around the world. In rivers used as waterways, ship passages contribute to the erosion of unprotected banks, but their short- and long-term impacts remain unclear. This work investigates the effects of navigation on bank erosion along a reach of the regulated Meuse...journal article 2020

Cordier, F. (author), Tassi, P. (author), Claude, N. (author), Crosato, A. (author), Rodrigues, S. (author), Pham Van Bang, D. (author)Rivers typically present heterogeneous bed material, but the effects of sediment nonuniformity on river bar characteristics are still unclear. This work investigates the impact of sediment size heterogeneity on alternate bars with a morphodynamic numerical model. The model is first used to reproduce a laboratory experiment showing alternate...journal article 2019

Bregoli, F. (author), Crosato, A. (author), Paron, P. (author), McClain, M.E. (author)The Lower Mara River and Wetland, Tanzania, is an important ecosystem and unique water resource for a vast semi-arid area. The river, an affluent of Lake Victoria, and the wetland are experiencing morphological and vegetation changes resulting in channel avulsions and wetland expansion. This study analyses the changes over the last 100 years...journal article 2019

Vargas-Luna, Andrés (author), Duro, G. (author), Crosato, A. (author), Uijttewaal, W.S.J. (author)While the scientific community has long recognized that alluvial rivers are the product of interactions between flowing water and bed material transport, it is increasingly evident that vegetation mediates these interactions and influences the stream channel characteristics. In a novel set of mobile bed laboratory experiments with variable...journal article 2019

Duro, G. (author), Crosato, A. (author), Kleinhans, Maarten G. (author), Winkels, Timotheus G. (author), Woolderink, Hessel A.G. (author), Uijttewaal, W.S.J. (author)Distinct bankline patterns appeared after the removal of protection works along a navigable reach of the Meuse River. A series of oblique embayments now dominate the riverine landscape after ten years of bank erosion, but their location and asymmetry cannot be explained yet. This work analyses and integrates field measurements of flow, ship...journal article 2019

Duro, G. (author), Crosato, A. (author), Kleinhans, Maarten G. (author), Uijttewaal, W.S.J. (author)We apply structure from motion (SfM) photogrammetry with imagery from an unmanned aerial vehicle (UAV) to measure bank erosion processes along a mid-sized river reach. This technique offers a unique set of characteristics compared to previously used methods to monitor banks, such as high resolution and relatively fast deployment in the field....journal article 2018

Duro, G. (author), Crosato, A. (author), Kleinhans, Maarten (author), Uijttewaal, W.S.J. (author)In recent years, many riverbanks in Europe had their protections removed to reactivate natural erosion processes and improve riparian habitats. Yet, other river functions may be affected, such as navigation and flood conveyance. The quantification and prediction of erosion rates and volumes is then relevant to manage and control the integrity...journal article 2018

Crosato, A. (author), Bonilla-Porras, José (author), Pinkse, Arthur (author), Tiga, Tsegaye Yirga (author)Long series of groynes are built from both river sides to narrow river channels and prevent bank erosion with the aim to improve the conditions for inland navigation and prevent lateral channel migration. Single groynes or short series of groynes are built to impede local bank erosion, deviate the water flow, free an intake or fix the...journal article 2018

Vargas Luna, A. (author), Crosato, A. (author), Byishimo, P. (author), Uijttewaal, W.S.J. (author)Alluvial rivers are shaped by sequences of water flows excavating their channels. Observations show that besides the magnitude, also the frequency and duration of streamflow oscillations might be important for the river channel formation. In addition, the river morphology appears influenced also by both size and degree of uniformity of the...journal article 2018

(author), McClain, Michael (author)The meandering Ribb River flows in northwest Ethiopia to Lake Tana, the source of the Blue Nile River. The river has already undergone changes due to several human interventions, such as embanking, sand mining, water extraction and lake level regulation for hydropower. At present, a dam and a weir are under construction to store and divert...journal article 2018

(author)The Mara River is the only perennial river of a vast semi-arid area, including the Mara Serengeti ecoregion in Kenya and Tanzania. The river sustains more than one million inhabitants and millions of wild animals. In its lower reaches, the Mara River forms a wide wetland before flowing into Lake Victoria. The wetland represents a rich ecosystem...abstract 2018

(author)The prediction of the morphological evolution of renaturalized streams is important for the success of restoration projects. Riparian vegetation is a key component of the riverine landscape and is therefore essential for the natural rehabilitation of rivers. This complicates the design of morphological interventions, since riparian vegetation...journal article 2018

Le, T.B. (author), Crosato, A. (author), Mosselman, E. (author), Uijttewaal, W.S.J. (author)To maintain a navigable channel and improve high-flow conveyance, engineers have recently proposed constructing longitudinal training walls as an alternative to the traditional transverse groynes. However, previous work has shown that the system of parallel channels created by a longitudinal training wall might be unstable in rivers with...journal article 2018

Le, T.B. (author), Crosato, A. (author), Uijttewaal, W.S.J. (author)Rivers have been trained for centuries by channel narrowing and straightening. This caused important damages to their ecosystems, particularly around the bank areas. We analyse here the possibility to train rivers in a new way by subdividing their channel in main and ecological channel with a longitudinal training wall. The effectiveness of...journal article 2018

Ali, Yasir S.A. (author), Paron, Paolo (author), Crosato, A. (author), Mohamed, Yasir A. (author)Sediment accumulation hampers optimal water resources management of reservoirs. In the Roseires Reservoir across the Blue Nile River, in Sudan, about 30% of the storage capacity has been lost by sedimentation before dam heightening (2012), despite regular sediment sluicing and flushing. At the same time, increasing soil erosion in the upper...journal article 2017
