Frontiers of (Pareto) Optimal and Sustainable Water Management for Hydropower and Ecology

David Andrew Barry, Paolo Perona, Amin Niayifar, Pierre Razurel

River regulation alters the natural flow regime of streams with consequent impacts on terrestrial and aquatic habitats of the riparian zone. The severity of such impacts can be modulated by changing the redistribution rules at water intakes and reservoirs. ...

Monitoring of Priority Substances in Sediments of Switzerland

Florian Frédéric Vincent Breider, Benoît Jean Dominique Ferrari, Maria del Carmen Casado Martinez

In Switzerland, surface waters are protected by the Swiss Water Protection Ordinance (OEaux) which stipulates that the water quality shall be such that: "the water, suspended matter and sediments contain no persistent synthetic substances to ensure the pro ...

Hydrological and Geomorphological Significance of Riparian Vegetation in Drylands

Paolo Perona

Drylands are regions encompassing hyperarid, arid, semiarid, or subhumid climatic conditions (see also Chap. 1). They include cold and warm subtropical deserts, savannas, and the Mediterranean environments. Our focus here is on warm drylands, which are gen ...

Gravel bars are sites of increased CO2 outgassing in stream corridors

Tom Ian Battin

Streams are significant sources of CO2 to the atmosphere. Estimates of CO2 evasion fluxes (fCO2) from streams typically relate to the free flowing water but exclude geomorphological structures within the stream corridor. We found that gravel bars (GBs) are ...

The impact of flood variables on riparian vegetation

Katarína Dzubáková, Peter Molnar

The riparian vegetation of Alpine rivers often grows in temporally dynamic riverine environments which are characterized by pronounced meteorological and hydrological fluctuations and high resource competition. Within these relatively rough conditions, rip ...

Optimizing turbine withdrawal from a tropical reservoir for improved water quality in downstream wetlands

Alfred Johny Wüest, Bernhard Wehrli

Large reservoirs in the tropics act as efficient nutrient traps and often develop hypoxic conditions in the hypolimnion. Both effects may have severe implications for aquatic ecosystems, such as limited primary production in downstream riparian agriculture ...

Using Silicate Mineral Particles for pH Control during in situ Bioremediation of Chlorinated Ethene Source Zones

Elsa Marina Lacroix

Soil and groundwater pollution by chlorinated solvents such as tricholorethene (TCE) and tetrachloroethene (PCE) is a frequent problem in the industrialized world. Chlorinated solvents, characterized by a low solubility and a density greater than water, fo ...

Hydrology of the Sudanian Savannah in West Africa, Burkina Faso

Theophile Mande

As in all semi-arid regions, Tambarga, a small village surrounded by national parks in the landlocked country of Burkina Faso, is affected by the seasonality of the local hydrology. Seasonal and spatial variability of rainfall shapes the livelihoods of rur ...

Technology’s Role in Proving Indirect Ecosystem Services and Monitoring their use, the example of a wireless network of meteorlogical stations and agroforestry trees in a West African Parkland

Jean-Claude Bolay, Marc Parlange, Alexandre Repetti, Natalie Claire Ceperley, Theophile Mande

The Gourmantche people of South Eastern Burkina recognize Sclerocarya birrea as a locally important agroforestry tree because of its cultural, agricultural, and nutritional value. Although it is understood to provide hydrologic benefits to surrounding crop ...

Impact of a large tropical reservoir on riverine transport of sediment, carbon, and nutrients to downstream wetlands

Alfred Johny Wüest, Bernhard Wehrli

Large dams can have major ecological and biogeochemical impacts on downstream ecosystems such as wetlands and riparian habitats. We examined sediment removal and carbon (C), nitrogen (N), and phosphorus (P) cycling in Itezhi-Tezhi Reservoir (ITT; area = 36 ...
