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 ...

Inception of Regular Valley Spacing in Fluvial Landscapes: A Linear Stability Analysis

Sara Bonetti, Shashank Kumar Anand

Incipient valley formation in mountainous landscapes is often associated with their presence at a regular spacing under diverse hydroclimatic forcings. Here we provide a formal linear stability theory for a landscape evolution model (LEM) representing the ...

Semi-analytical solution of flow to a well in an unconfined-fractured aquifer system separated by an aquitard

David Andrew Barry

Semi-analytical solutions are presented for flow to a well in an extensive homogeneous and anisotropic unconfined-fractured aquifer system separated by an aquitard. The pumping well is of infinitesimal radius and screened in either the overlying unconfined ...

Multiple Inflow Branches at Supercritical-Type Vortex Drop Shaft

Michael Pfister, Jean-Marc Ribi, Corrado Gisonni, Gaetano Crispino, Thierry Fuchsmann

Vortex drop shafts serve to overcome important elevation differences in drainage systems. If well designed, they are performant in terms of energy dissipation and safety. However, the standard design requires well-defined approach flow conditions to ensure ...

Junction chamber at vortex drop shaft: case study of Cossonay

Michael Pfister, Corrado Gisonni, David Dorthe, Gaetano Crispino, Thierry Fuchsmann

The drainage network of the city of Cossonay (Switzerland) is currently being adapted for future needs. In particular, it is required to drain increased storm discharges due to a population augmentation and to provide an adequate concept to overcome unfavo ...

Transport of fluorobenzoate tracers in a vegetated hydrologic control volume: 1. Experimental results

Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Francesco Giuseppe Miglietta, Gianluca Botter

This paper reports about the experimental evidence collected on the transport of five fluorobenzoate tracers injected under controlled conditions in a vegetated hydrologic volume, a large lysimeter (fitted with load cells, sampling ports, and an undergroun ...

Analysis of Ballast Transport in the Event of Overflowing of the Drainage System on High Speed Lines

Giovanni De Cesare, Tamara Ghilardi, Mona Jafarnejad Chaghooshi, Elena Battisacco

The transport of ballast caused by the overflowing of longitudinal drains is a prime example of the interactions between the railway track and its environment. In such conditions, water flowing from the platform, along with debris, may drag the ballast off ...

Non-stationarity of solute travel time distribution observed in a controlled hydrologic transport volume

Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Gianluca Botter

Experimental data were collected over a year-long period in a transport experiment carried out within a controlled transport volume (represented by a 2m-deep, 1m-diameter lysimeter fitted with bottom drainage). The soil surface was shielded from natural ra ...

The importance of drainage system in railway tunnels and possibilities to reduce the LCC

Federica Sandrone

This paper will present the current state of drainage systems in new and existing SBB-railway tunnels. The fundamental drainage concepts, their limits as well as the LCC will be considered. The problems linked with the water pressure, its quantity and chem ...

Geomorphic Signatures on Brutsaert Base Flow Recession Analysis: case study of 27 Swiss catchments

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

Recession flow analysis are crucial in many areas of water resource management and useful to forecast base flow in gauged rivers. Moving from a classical recession curve analysis method, a large set of recession curves has been analyzed from Swiss streamfl ...
