Sediment replenishment combined with an artificial flood improves river habitats downstream of a dam

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Severin Stähly, Christopher Robinson

River reaches downstream dams where a constant residual flow discharge is imposed, often lack sediment supply and periodic inundation due to the absence of natural flood events. In this study, a two-year return flood was released from an upstream reservoir ...

Vertex: A New Distributed Underwater Robotic Platform for Environmental Monitoring

Alcherio Martinoli, Alexander Bahr, Felix Stephan Schill

We present a new Autonomous Underwater Vehicle (AUV) system for cooperative environmental sensing. The AUV was specifically developed as a platform for distributed, cooperative sensing in lakes and coastal areas. In this paper we describe the prerequisite ...

Simulating Biogenic Secondary Organic Aerosol During Summertime in China

Athanasios Nenes, Mengmeng Li

Biogenic secondary organic aerosol (BSOA) contributes significantly to summertime organic particulate matter. In this study, a simulation of BSOA for summer 2012 over China is performed using the Community Multiscale Air Quality model with an explicit repr ...

Influence of Operational Timing on the Efficiency of Venting Turbidity Currents

Anton Schleiss, Giovanni De Cesare, Sabine Chamoun

Reservoir sedimentation is gaining growing attention as dams are aging, due to economic and environmental consequences. Venting of turbidity currents is one of many sediment management techniques, highly recommended when water is in shortage. The venting o ...

Time-based failure analysis of compressed riverbank riprap

Anton Schleiss, Charles Pfister, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi

Methods to design riprap-lined channels usually refer to dumped material. Large blocks placed individually by machinery are used when more stability is required. They offer additional resistance against flow erosion since space between blocks is minimized ...

Prediction and forecast of Suspended Sediment Concentration (SSC) on the Upper Yangtze basin

Mário Jorge Rodrigues Pereira Da Franca, José Pedro Gamito de Saldanha Calado Matos

Sediment transport in suspension may represent 90% or more of the global annual flux of sediment. For instance, more than 99% of the sediment supplied to the sea by the Yangtze River is suspended load. Suspended load is an important component for understan ...

Assessing the Hydro-Morphodynamic Response of a Beach Protected by Detached, Impermeable, Submerged Breakwaters: A Numerical Approach

Coastal areas host a large fraction of the world's population and are exposed to natural extreme events, which are a serious threat to human life, as well as to economies. For this reason, sea storms are increasingly the object of studies, and the design o ...

Coastal Education & Research Foundation2016

This is the second of two papers on the 3D numerical modeling of nearshore hydro- and morphodynamics. In Part I, the focus was on surf and swash zone hydrodynamics in the cross-shore and longshore directions. Here, we consider nearshore processes with an e ...
