Spatiotemporal Dynamics of Flow and Hydrochemistry in Drainage Networks

Despite their high ecological value, non-perennial streams have received less attention than their perennial counterparts. This doctoral thesis addresses this disparity by advancing knowledge on the dynamics of the drainage density and hydrologic processes ...

Different erosion and entrainment mechanisms in snow avalanches

Johan Alexandre Philippe Gaume, Betty Sovilla, Xingyue Li

Erosion significantly affects the dynamics of gravity-driven mass flows. In snow avalanches, the snow cover can be substantially eroded but only partially entrained, however, there are very limited investigations to substantiate this difference. Here, we s ...

The effect of accelerated soil erosion on hillslope morphology

Sara Bonetti

Intensive agricultural land use can have detrimental effects on landscape properties, greatly accelerating soil erosion, with consequent fertility loss and reduced agricultural potential. To quantify the effects of such erosional processes on hillslope mor ...

Monthly to decadal evolution of sandy beaches in the Pittwater estuary

Vincent Henri De Staercke

Even if the total length of shorelines in low-wave environments like bays, sounds, lagoons and estuaries greatly exceed that of open-ocean coasts, the morphodynamics of such systems are poorly understood. Only few studies developed models to predict change ...

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 ...

Field study on drainage densities and rescaled width functions in a high‐altitude alpine catchment

Andrea Rinaldo, Marc Parlange, Raphaël Mutzner

This paper addresses the effect of accurately mapping spatially heterogeneous drainage densities in high-altitude alpine basins on Rescaled Width Functions (RWFs), used in some applications as a minimalist model of the hydrologic response. The channel netw ...

Basal entrainment by Newtonian gravity-driven flows

Christophe Ancey, Nicolas Andreini, Belinda Margaret Bates

Gravity-driven flows can erode the bed along which they descend and increase their mass by a factor of 10 or more. This process is called basal entrainment. Although documented by field observations and laboratory experiments, it remains poorly understood. ...

Coupled semi‐analytical approach of CO2 injection induced caprock deflection

Lyesse Laloui, Chao Li

This study focuses on a specific problem related to the caprock deformation induced by the in-jection of CO2 at depth. The adopted methodology includes the development of a mathematical model that incorporates the deformable behaviour of storage media and ...

Impacts of irrigation with industrial treated wastewater on soil properties

André Mermoud, Pascal Boivin

Wastewater reuse in agriculture is a widespread practice in developing countries, especially in urban areas where water shortage and poverty encourage people to use that marginal resource. Raw or treated wastewaters are used by farmers, but even treated wa ...

Geomorphic signatures on brutsaert base flow recession analysis

Andrea Rinaldo, Marc Parlange, Enrico Bertuzzo, Steven Vincent Weijs, Raphaël Mutzner, Serena Ceola, Ludovico Nicotina, Nevena Tomasic

This paper addresses the signatures of catchment geomorphology on base flow recession curves. Its relevance relates to the implied predictability of base flow features, which are central to catchment-scale transport processes and to ecohydrological functio ...
