Morphometry of Tidal Meander Cutoffs Indicates Similarity to Fluvial Morphodynamics
Sinuous channels wandering through coastal wetlands have been thought to lack lateral-migration features like meander cutoffs and oxbows, spurring the broad interpretation that tidal and fluvial meanders differ morphodynamically. Motivated by recent work s ...
Washington2024Enhancing Flood Resilience: Sediment Management in Le Bez Torrent
Giovanni De Cesare, Azin Amini, Romain Nathan Hippolyte Merlin Van Mol
In the canton of Bern, Switzerland, the “Le Bez” torrent is known for its flash floods, causing sediment and wood debris buildup in Villeret village settled on the alluvial fan. To mitigate this issue, a sediment/wood trap system is being implemented upstr ...
Swiss Academy of Sciences (SCNAT)2023Interplay of S and As in Mekong Delta sediments during redox oscillations
Rizlan Bernier-Latmani, Laurent Louis José Charlet
The cumulative effects of periodic redox cycling on the mobility of As, Fe, and S from alluvial sediment to groundwater were investigated in bioreactor experiments. Two particular sediments from the alluvial floodplain of the Mekong Delta River were invest ...
CHINA UNIV GEOSCIENCES, BEIJING2019Hydraulic Reconstruction of the 1818 Gietro Glacial Lake Outburst Flood
Christophe Ancey, Tomás Alfredo Trewhela Palacios, Eric Bardou, Martin Funk
In the spring of 1818, ice avalanches from the Gietro Glacier created an ice dam, which in turn formed a glacial lake in the Drance Valley (Canton of Valais, Switzerland). Today, its maximum volume is estimated to have been 25x10(6) m(3). Cantonal authorit ...
2019Microbially Mediated Release of As from Mekong Delta Peat Sediments
Rizlan Bernier-Latmani, Manon Frutschi, Karen Elda Viacava Romo, Yuheng Wang, Luca Loreggian
Peat layers within alluvial sediments are considered effective arsenic (As) sinks under reducing conditions due to the binding of As(III) to thiol groups in natural organic matter (NOM) and the formation of As-bearing sulfide phases. However, their possibl ...
2019Hydro-morphological processes through permeable sediment traps at mountain rivers
In alpine regions, villages are often situated near alluvial fans, which are fed by mountain rivers transporting high sediment load during floods. In the past, these mountain rivers on the alluvial fans have often been channelized near urbanized areas, whe ...
EPFL-LCH2017Sediment Pulses in a Gravel-Bed Flume with Alternate Bars
The proper understanding of gravel-bed river dynamics is a crucial issue for the effective protection against related natural hazards, design of hydraulic structures, and preservation of their high ecological value in mountain regions. However, despite mor ...
EPFL2017Effects of endogeic earthworms on the soil organic matter dynamics and the soil structure in urban and alluvial soil materials
Pascal Turberg, Jean-Michel Gobat, Renée-Claire Le Bayon
Earthworms are considered as key actors of soil processes at different spatial and temporal scales and provide essential ecosystem services linked to climate regulation or primary production. However, little is known about their basic functional roles (e.g ...
