Deltas are very sensitive environments and highly vulnerable to variations in water discharge and the amount of suspended sediment load provided by the delta-forming currents. Human activities in the watershed, such as building of dams and irrigation ditch ...
Experiments involving both a circular wall jet and an impinging jet were conducted, as occurring at irrigation control structures or at dams with combined crest and low-level spillways. The effects of the non-dimensional parameters on the scour hole dimens ...
The scarcity of freshwater resources is a critical problem in semi-arid zones and marginal quality water is increasingly being used in agriculture. This paper aimed at evaluating the physico-chemical and biological risks on irrigated soils and fruits of ma ...
The present study takes place in Ouagadougou (Burkina Faso), a typical Sub-Saharan city where water shortage and food crisis necessitate wastewater reuse in urban agriculture. Different issues linked to this practice were studied in two components separate ...
In this paper, a linear tubular generator is presented. It is used for an energy harvesting system equipped in a footwear, scavenging power from forward motion during a walk. Configuration of the generator is studied, and geometric optimization by finite-e ...
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 ...
The energy services delivered to urban areas in Switzerland make up more than 45% of the national energy consumption. Thus, in the framework of the Tetraener European project, a methodology has been developed to design low temperature thermal networks base ...
The relative influences of hydrologic processes and biogeochemistry on the transport and retention of minor solutes were compared in the riverbed of the lower Merced River (California, USA). The subsurface of this reach receives ground water discharge and ...
In the present study, a high energy pulsed laser is used to generate a millimetric cavitation bubble within a water °ow over a symmetric hydrofoil. The bubble is initiated at di®erent locations in the vicinity of the hydrofoil leading edge. A high speed ca ...
In this dissertation, we explore the potential of wireless sensor networks (WSNs) in an original context, the small agriculture of Developing Countries (DCs). Our goal is to confront an emerging technology with a concrete problem of world-wide dimensions, ...
