Cross-shore sediment transport estimation using fuzzy inference system in the swash zone

The interactions between fluid and sediment in the swash zone dominate the erosion or accretion of the beach, and they act as boundary conditions for nearshore hydrodynamic and morphodynamic models. Thus, the evaluation of sediment transport is of particul ...

Flood Management in a Complex River Basin with a Real-Time Decision Support System Based on Hydrological Forecasts

Javier García Hernández

During the last decades, the Upper Rhone River basin has been hit by several flood events causing significant damages in excess of 500 million Swiss Francs. From this situation, the 3rd Rhône river training project was planned in order to improve the flood ...

Sustainable soil and water resources: modelling soil erosion and its impact on the environment

David Andrew Barry

With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of land to intensive agriculture has led to dramatic decreases ...

The geomorphic origin of recession curves

Nevena Tomasic

An important study domain in hydrology is dedicated to understand how the spatial organization of river networks is reflected in the hydrologic response to rainfall inputs (Biswal and Marani, 2010). Base flow (or recession flow) is the discharge rate in a ...

Ability of One-Dimensional Hairsine-Rose Erosion Model to Predict Sediment Transport over a Soil with Significant Surface Stones

David Andrew Barry, Seifeddine Jomaa

Surface stones affect erosion rates by reducing raindrop-driven detachment and protecting the original soil against overland flow induced-hydraulic stress. The aims of this study were, (i) to quantify how the stone characteristics affect the total sediment ...

Signature-based model calibration for hydrologic prediction in mesoscale Alpine catchments

Bettina Schaefli, Abdelkader Mezghani

This paper presents a calibration framework for a precipitation-runoff model for flood prediction in a mesoscale Alpine basin with strongly anthropogenic discharges. The developed methodology addresses two classical hydrological calibration challenges: com ...

Exact solutions of the Hairsine-Rose precipitation-driven erosion model for a uniform grain-sized soil

David Andrew Barry, Seifeddine Jomaa

Hairsine and Rose developed a mechanistic, one-dimensional, precipitation-driven erosion model that, since its appearance, has been validated by several sets of experimental results. The model allows any sediment particle to be present in one of three zone ...

Semi-empirical model for channel bed evolution due to lateral discharge withdrawal

Anton Schleiss, Burkhard Rosier

Side weirs and overtopable levees are widely used to increase flood routing along a channel or river. The lateral loss of water reduces the sediment transport capacity leading to the formation of a local sediment deposit close to the overflow. Since the ex ...

Ability of One-Dimensional Hairsine-Rose Erosion Model to Predict Sediment Transport over a Soil with Significant Surface Stones

David Andrew Barry, Seifeddine Jomaa

Surface stones affect erosion rates by reducing raindrop-driven detachment and protecting the original soil against overland flow induced-hydraulic stress. Numerous studies have shown that the effect of surface stones on erosion depends on both the stone c ...

Effect of stone coverage on soil erosion

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Soil surface coverage has a significant impact on water infiltration, runoff and soil erosion yields. In particular, surface stones protect the soils from raindrop detachment, they retard the overland flow therefore decreasing its sediment transport capaci ...
