Large-scale floodplain sediment dynamics in the Mekong Delta : present state and future prospects
… one of the world’s most productive fisheries. Sediment dynamics play a major role for the high productivity of agriculture and fishery in the delta. However, the MD is threatened by climate change, sea level rise and unsustainable development activities in the Mekong Basin. But despite its …

River-Floodplain Connectivity and Sediment Transport Potential: Applications to Sediment Dynamics on Floodplains and Juvenile Freshwater Mussel Settling in Rivers
River-floodplain connectivity is the degree of water-driven transport of matter, energy, and organisms between rivers and their floodplains. Recent advancement of high-resolution lidar data and numerical modeling is helpful to explore river-floodplain connectivity precisely to improve our …

Exploring Overbank Sediment Deposition Variation in Heavily Modified Floodplains of the Lower Mississippi River: A Sedimentological and Geophysical Analysis
… to the channel profile and surrounding floodplains through dams, dikes, revetments, dredging, and channel cutoffs. Although these changes have improved navigation and reduced flood risk, unanticipated changes to the major flood return period, individual flood severity and duration, and …

Influence of Terrain, Vegetative, and Hydraulic Properties on Sediment and Microplastic Accumulation in the Stroubles Creek Floodplain
Sediment and microplastic accumulation in stream systems occur when particulates entrained in overbank flow are retained by the floodplain. Despite overbank flow conditions dictating sediment and microplastic accumulation, the spatial distribution of accumulation within floodplains remains poorly …

How do sand-bed meandering rivers co-construct their own bankfull discharge and bankfull channel geometry? Analytical and numerical study
… authors of their own geometry. Given water and sediment, a river constructs its own well-defined channel and floodplain. This channel is characterized by a bankfull width and depth, longitudinal slope, and bankfull discharge when the flow spills out onto the floodplain. No specific discharge is …

Exploring fine sediment dynamics and the uncertainties associated with sediment fingerprinting in the Nene river basin, UK
… and ecological status of freshwater bodies. Fine sediment has been shown to be a major cause of the degradation of lakes and rivers, and as a result research in geomorphology has been directed towards the understanding of fine sediment dynamics. It was identified by a review of published …

From meander bend to oxbow lake: morphodynamics and sedimentology of chute cutoffs
… river channel, excavating a large volume of floodplain sediment as the chute channel deepens and widens. Bar development at the upstream and downstream ends of the cutoff channel leads to abandonment of the bend and formation of an oxbow lake, which, together with oxbow lake sedimentation, …

Γεωχημική μελέτη των ιζημάτων του πυθμένα και της λεκάνης απορροής της Λίμνης της Καστοριάς
Οι κύριοι στόχοι αυτής της διατριβής ήταν: (α) η γεωχημική χαρτογράφηση της σημερινής κατάστασης των επιφανειακών λιμναίων ιζημάτων της Λίμνης της Καστοριάς (Οκτώβριος 2010), (β) η αποτύπωση της παλαιότερης κατάστασης, όπως αυτή καταγράφεται στα υπο-επιφανειακά λιμναία ιζήματα, (γ) η χαρτογράφηση …
