Giri, Sanjay (author), Thompson, Angela (author), Donchyts, Gennady (author), Oberhagemann, Knut (author), Mosselman, E. (author), Alam, Jahagir (author)This paper presents a hydraulic and morphological analysis of the Lower Jamuna in Bangladesh with a focus on two key bifurcations that are important for stabilization of the Lower Jamuna reach. We used ground measurements, historical data, multispectral satellite images from various sources as well as numerical models. We carried out hydraulic...journal article 2021

Giri, Sanjay (author), Thompson, Angela (author), Mosselman, E. (author), Donchyts, Gennadii (author)In this paper, we present flow and erosion problems in selected reaches of two large and dynamic river systems in South Asia, namely the Koshi River in Nepal (and India) and the Lower Brahmaputra (Jamuna) in Bangladesh. We attempted to analyse large- and meso-scale (short- and medium-term) morphological changes with a focus on the dynamics of...conference paper 2019

Singh, Umesh (author), Crosato, A. (author), Giri, Sanjay (author), Hicks, Murray (author)The effects of sediment heterogeneity and sediment mobility on the morphology of braided rivers are still poorly studied, especially when the partial sediment mobility occurs. Nevertheless, increasing the bed sediment heterogeneity by coarse sediment supply is becoming a common practice in river restoration projects and habitat improvement...journal article 2017

Bricker, J.D. (author), Schwanghart, W. (author), Raj Adhikari, B. (author), Moriguchi, S. (author), Roeber, Volker (author), Giri, S. (author)The 2015 magnitude 7.8 Gorkha earthquake and its aftershocks weakened mountain slopes in Nepal. Co- and postseismic landsliding and the formation of landslide-dammed lakes along steeply dissected valleys were widespread, among them a landslide that dammed the Kali Gandaki River. Overtopping of the landslide dam resulted in a flash flood...journal article 2017

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

Effect of the barrage and embankments on flooding and channel avulsion case study Koshi River, NepalDevkota, L. (author), Crosato, A. (author), Giri, S. (author)Humans have utilized water resources for millennia by modifying natural river courses and such interventions have greatly influenced not only river flows and sediment fluxes, but also the overall river morphology. Situated in the Nepal's eastern Ganges region, the braided Koshi River is unique among the other rivers, because of the high...journal article 2012

Verheij, H.J. (author), Hoffmans, G. (author), Den Adel, H. (author), Akkerman, G.J. (author), Giri, S. (author)A desk study has been carried out regarding interface stability of granular filter structures. Actually, the project focuses on two particular aspects: (1) interface stability as function of the thickness of the filter layer consisting of standard armourstone gradings, and (2) interface stability of gravel mixtures with a wide gradation The...report 2009
