Technical note: Two-component electrical-conductivity-based hydrograph separation employing an exponential mixing model (EXPECT) provides reliable high-temporal-resolution young water fraction estimates in three small Swiss catchments

The young water fraction represents the portion of water molecules in a stream that have entered the catchment relatively recently, typically within 2-3 months. It can be reliably estimated in spatially heterogeneous and nonstationary catchments from the a ...

Estimating pollution spread in water networks as a Schrödinger bridge problem with partial information

Isabel Haasler

Incidents where water networks are contaminated with microorganisms or pollutants can result in a large number of infected or ill persons, and it is therefore important to quickly detect, localize and estimate the spread and source of the contamination. In ...

Through the Jura mountains: a path of productive nature

In most people’s imagination, the Jura Mountains are a wild and untouched landscape. However, what we now perceive as typical of the region is the outcome of centuries of modifications to make it more hospitable and productive. The accompanying Enoncé Port ...

Steel, a material to reuse

Corentin Jean Dominique Fivet

The destructive impact of the construction industry on the planet and its inhabitants is no longer in question. Global warming, waste management, depletion of natural resources, air and soil pollution are all issues that must be urgently addressed. They ar ...

Applicability of the landscape evolution model in the absence of rills

David Andrew Barry, Andrea Rinaldo, Paolo Perona, Seifeddine Jomaa, Mohsen Cheraghi, Andrea Cimatoribus

Despite numerous applications of physically-based models for incised landscapes, their applicability for overland flow on unchanneled surfaces is not known. This work challenges a widely used landscape evolution model for the case of non-uniform rainfall a ...

Can runoff event types explain some scatter in nitrate C-Q relationships?

Jana Freiin von Freyberg

Nitrate contamination of rivers from agricultural sources, is a challenging problem for water quality management. The relationship between solute concentrations and streamflow rates (C-Q) observed at catchment outlets provide useful information on hydrolog ...

Business power and the regulation of pollution: oil refineries in Switzerland in the early 1960s

Nicolas Christophe Chachereau

In the late 1950s and in the 1960s, in response to the surge of gasoline and fuel oil consumption, several international oil companies planned the building of refineries in Switzerland, linked to European pipelines. Two were realized, out of four propositi ...

Nutrient pollution enhances productivity and framework dissolution in algae- but not in coral-dominated reef communities

Nils Rädecker, Hal Hunt Jones II

Ecosystem services provided by coral reefs may be susceptible to the combined effects of benthic species shifts and anthropogenic nutrient pollution, but related field studies are scarce. We thus investigated in situ how dissolved inorganic nutrient enrich ...

Hydrological trends and the evolution of catchment research in the Alptal valley, central Switzerland

Jana Freiin von Freyberg, Ilja van Meerveld

When the observation of small headwater catchments in the pre-Alpine Alptal valley (central Switzerland) started in the late 1960s, the researchers were mainly interested in questions related to floods and forest management. Investigations of geomorphologi ...

Valorization of calcium phosphite waste as phosphorus fertilizer: Effects on green manure productivity and soil properties

Alexandre Buttler, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja, Mario Fontana

The potential to use calcium phosphite (Ca-Phi) as phosphorus (P) fertilizer may represent an effective recycling of P-containing by-products. A greenhouse experiment was conducted to investigate the effect of Ca-Phi (38 kg P ha(-1)) on soil properties and ...
