Bregolia, Francesco (author), Crosato, A. (author), Paron, Paolo (author), McClain, M.E. (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

Mulatu, C.A. (author), Crosato, A. (author), Mynett, A.E. (author)The Ribb River is one of the components of the Blue Nile River system located in the North Western part of Ethiopia. It drains to Lake Tana, the source of the Blue Nile River. The Ribb has a length of 130 km, with a catchment area of 1,812 km2. The average yearly rainfall of the catchment is 1300 mm, with...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

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

Liu, J. (author), Bregoli, Francesco (author), Crosato, A. (author), Calvani, Giulio (author)Working as natural filter, well-designed vegetation schemes have been widely applied to improve the quality of water (Aiona, 2013; Stefanakis, 2015). Proper design, however, requires appropriate physics-based modelling of their filtering capacity. Several theoretical models predicting sediment transport in vegetated flow have been proposed:...abstract 2024

Crosato, A. (author)River morphology can be described at different scales: at the basin scale we distinguish the river network; at the reach scale the planform, the slope and average features, such as the width and bankfull water depth; at the cross-section scale the transverse variations of river bed topography; and at smaller scales we observe bedforms and...abstract 2024

Rivera-Soler, L. (author), Vargas-Luna, A. (author), Giraldo-Osorio, J. D. (author), Crosato, A. (author)Meandering rivers dynamics has intrigued scientists since the nineteen fifties (Hooke, 2013). Meander migration models are regularly used to predict planimetric changes (Crosato, 2018), but they have not considered the figure, the reconstructed historical channel is shown. This alignment was obtained from the analysis of the existent water marks...abstract 2023

Samir-Saleh, M. (author), Crosato, A. (author)Flume experiments and field observations demonstrating the effects of vegetation on river planforms are reported in literature, but numerical studies of these effects at the river scale are lacking. We investigated the effects of vegetation in a 2D morphodynamic model using submodels for flow resistance and colonisation of newly formed deposits....conference paper 2010

Singh, U. (author), Crosato, A. (author), Giri, S. (author), Hicks, M. (author), Mynett, A. (author)Recent studies have shown that the river bed topography is very sensitive to the composition of bed sediment. So, human interventions and natural processes leading to changes in sediment size grading might result in morphological adjustments of river reaches. This study deals with the effects of changing sediment size grading on the braiding...conference paper 2013

Crosato, A. (author), Getaneh, A.A. (author), Desta, F.B. (author), Uijttewaal, W.S.J. (author), Le, U. (author)The current view is that migrating bars are the result of morphodynamic instability in straight or mildly-sinuous alluvial channels and are therefore an inevitable feature of alluvial river beds. Steady bars, instead, require some external forcing or specific morphodynamic conditions to develop. Yet, recent numerical tests showed that steady...conference paper 2010

Duran, R. (author), Beevers, L. (author), Crosato, A. (author), Wright, N. (author)Lack of data is often considered a limitation when undertaking morphological studies. This research deals with morphological studies of small rivers experiencing bank erosion processes when only limited data are available. A reach of the meandering gravel-bed river Irwell (United Kingdom) is taken as a case study in order to analyze the bank...conference paper 2010

Crosato, A. (author), Desta, F.B. (author), Cornelisse, J. (author), Uijttewaal, W.S.J. (author)Migrating alternate bars form in alluvial channels as a result of morphodynamic instability. Extensive literature can be found on their origin and short-term development, but their long-term evolution has been poorly studied so far. In particular, it is not clear whether they eventually reach an equilibrium shape, since short-term experiments...conference paper 2011

Ali, Y.S.A. (author), Omer, A.Y.A. (author), Crosato, A. (author)Roseires Reservoir is located on the Blue Nile River, in Sudan (figure 1). It is the first trap to the sediments coming from the upper catchment in Ethiopia, which suffers from high erosion and desertification problems. The reservoir lost already more than one third of its storage capacity due to sedimentation in the last four decades. This is a...conference paper 2013

Crosato, A. (author), Desta, F.B. (author)Alternate bars in straight alluvial channels are migrating or steady. The currently accepted view is that they are steady only if the width-to-depth ratio is at the value of resonance or if the bars are forced by a steady local perturbation. Experimental observations, however, seem to indicate that steady bars are also present in cases of...conference paper 2009
