Design of sediment detention basins: Scaled model experiments and application

Anton Schleiss, Sebastian Schwindt, Mona Jafarnejad Chaghooshi, Anita Hélène Roth

Sediment detention basins are implemented on mountain rivers to trap solid material that may aggravate the flooding of downstream settlements. However, retention structures built in the past may unnecessarily retain sediment during non-hazardous flood even ...

Preferential Deposition of Snow and Dust Over Hills: Governing Processes and Relevant Scales

Michael Lehning, Marc Parlange, Francesco Comola, Marco Giovanni Giometto

Preferential deposition of snow and dust over complex terrain is responsible for a wide range of environmental processes and accounts for a significant source of uncertainty in the surface mass balances of cold and arid regions. Despite the growing body of ...

Sediment replenishment: Influence of the geometrical configuration on the morphological evolution of channel-bed

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Elena Battisacco

Dams trap sediment in the upstream reservoir, which may lead to river bed armoring, streambank erosion and failure, channel incision and reduction of the morphological diversity in the downstream river reaches. The replenishment of sediment is a mitigation ...

Influence of consecutive sediment replenishment on channel bed morphology

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Elena Battisacco, Lena Bösch

Dams interrupt the longitudinal connectivity of a river as they store water and trap sediment. When transport capacity downstream of dams exceeds sediment supply, water becomes hungry and channel incision, bed armouring and reduction of morphological diver ...

Evaluation of geochemical and hydrogeological processes by geochemical modeling in an area affected by evaporite karstification

The Ebro Valley in the outskirts of Zaragoza (NE Spain) is severely affected by evaporite karstification, leading to multiple problems related to subsidence and sinkhole formation. In this work, a combination of inverse (mixing + mass-balance) and forward ...

Reservoir Sediment Management Using Replenishment : A Numerical Study Of Nunome Dam

Anton Schleiss, Sameh Ahmad Kantoush, Sébastien Cajot

Improving the integration of dams in the natural environment and recovering their storage capacity lost to sedimentation are two topics of growing concern. To address these two issues, the accumulated sediments are being relocated down into the dam's tail ...

The 8.2 ka event and early-mid Holocene forest, fires, and flooding in the Central Ebro Desert, NE Spain

Basil Andrew Stansfield Davis

The impact of the 8.2 ka cooling event during the Early–Mid Holocene has not been widely observed in Southern Europe, which in contrast to Northern Europe, was already experiencing a cooler than present climate at this time. Multi-proxy analysis of sedimen ...

Paleohydrological fluctuations and steppe vegetation during the last glacial maximum in the central Ebro valley (NE Spain)

Basil Andrew Stansfield Davis

Combined analysis of sedimentary facies, geochemistry and pollen from lake sediment records, and sedimentological and palynological studies from slope deposits allow the characterization of vegetation and lake level status during the Last Glacial (LGM) in ...

Responses of a saline lake ecosystem in a semiarid region to irrigation and climate variability- The history of Salada Chiprana, central Ebro basin, Spain

Basil Andrew Stansfield Davis

To adequately manage the fragile and changing environments of semiarid regions it is essential to disentangle human from climate or other environmental impacts over longer timescales than human memory. We investigated sediment cores from Salada Chiprana, a ...
