The Role of Biochar and Peatlands in Reaching Swiss Net Zero

This master thesis explores the role of Biochar production and Peatlands renaturation as Nature-based solutions to reach Swiss Net Zero by 2050, by analyzing the historical, socio-economic context, and the scientific phenomena behind these topics. It aimed ...

Dynamic Effective Porosity Explains Laboratory Experiments on Watertable Fluctuations in Coastal Unconfined Aquifers

David Andrew Barry, Zhaoyang Luo

Watertable fluctuations are a characteristic feature of coastal unconfined aquifers. They interact with the vadose zone creating a dynamic effective porosity, for which a new (empirical) expression is proposed based on a dimensionless parameter related to ...

Effects of large macropores on soil evaporation in salt marshes

David Andrew Barry

The occurrence of macropores in salt marsh sediments is a natural and ubiquitous phenomenon. Although they are widely assumed to affect pore-water flow in salt marshes significantly, the mechanisms involved and their extent are not well understood. We cond ...

Producing Policy-relevant Science by Enhancing Robustness and Model Integration for the Assessment of Global Environmental Change

Marc Vielle, Frédéric Louis François Babonneau, Santosh Ram Joshi, Alain Haurie

We use the flexible model coupling technology known as the bespoke framework generator to link established existing modules representing dynamics in the global economy (GEMINI-E3), the energy system (TIAM-WORLD), the global and regional climate system (MAG ...

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 ...

Transition of the Swiss Phosphorus System towards a Circular EconomyPart 2: Socio-Technical Scenarios

Claudia Rebeca Binder Signer, Jonas Ramon Mehr

A transition towards a circular economy of phosphorus (P) in Switzerland is a multi-faceted challenge as P use is subject to a variety of influencing factors comprising policy interventions, consumption trends, or technological innovations on different spa ...

Improving slash-and-burn agriculture in Central Menabe, Madagascar

Justine Marie Gay des Combes

Slash-and-burn agriculture is considered as an important driver of deforestation in the tropics. In Madagascar, a biodiversity hotspot, this type of agriculture particularly threatens the tropical forest cover. On the south-western coast of the island, in ...
