Projects

drought.ch @ BAFU

Das Ziel dieses Projekts ist die Erarbeitung eines Konzeptes für die Überführung von Elementen der bestehenden Forschungsplattform drought.ch in den operationellen Betrieb beim BAFU sowie eine Integration bei naturgefahren.ch.

Wasserkraftwerkportfolio "ewz"

Für die Elektrizitätswerk der Stadt Zürich ("ewz") soll eine Übersicht zum zukünftigen Wasserdargebot in den Kraftwerke ihren Portfolio erstellt werden. Die Ergebnisse sollen für den heutigen und künftigen Wasserverfügbarkeit bereitgestellt werden.

Wasserdargebot Kanton Zürich

In dieser Studie wurden anhand der CH2018 Klimaszenarien und den hydrologischen Projektionen Hydro-CH2018, Abflussszenarien (also das zukünftige Wasserdargebot) für den Kanton Zürich erstellt.

Wasserbilanz der Schweiz

Modellgestützte Bilanzierung des Wasserhaushaltes der Grosseinzugsgebiete der Schweiz

Lake regulations

With the help of climate scenarios CH2018 and various models, we produce projections of the regulation of Swiss lakes until the end of the century.

Alpine Drought Obvservatory

According to the Alpine Convention, water scarcity and related conflicts are becoming a worrying topic in many Alpine regions, depending on water from snowmelt and glaciers.

Niedrigwasserdauerkurven

Der Bedarf nach einer solideren Grundlage für die Abschätzung von Niedrigwasserabflüssen in ungemessenen Gebieten ist im Nachgang zu den Trockenheitsereignissen der Jahre 2003, 2011, 2015 und 2018 gestiegen. Die massgebenden Speicher und Einflussfaktoren wie zum Beispiel Versickerungsstrecken werden

On future water resources in Switzerland"

Continuing climate change modifies the water supply and accentuates the pressure from competing water uses.

Seeregulierung und Klimawandel

Mit den vorgesehenen Untersuchungen soll die Wirksamkeit der Seeregulierungs-Vorschriften basierend auf den Klimaszenarien CH2018 überprüft werden. Eine mehrstufige Studie klärt den Handlungsbedarf bei den Regulier-Reglementen.

Demonstrator for flexible SHP (SmallFlex): Real-time hydrological forecasts

Hydro-CH2018: Multiple use of reservoirs

This synthesis work aims at identifying the potential of reservoirs (such as natural and artificial lakes, storage dams and other reservoirs) to mitigate future drought situations both at the national (Swiss) scale, but also for specific case study areas.

HYDRO-CH2018 "Forhycs-Ice"

In the project FORHYCS-ICE, ("Forest, Glacier and Hydrology Change in Switzerland"), we aim at providing the first holistic simulations of climate impacts (CH2018 scenarios) on water resources, glaciers and forests.

Prediction of hydrological drought

SREP-drought will evaluate how summer low flows and droughts are affected by winter snowpack in three catchments (Prealps, central Switzerland; Jizera Mountains, northern Czech Republic; Little Caucasus, central Georgia).

Ensemble predictions

The project HEPS4Power explores the use of extended-range hydrological ensemble predictions systems (HEPS) for improving the operations and revenues of hydropower systems.

FORHYCS

A hydrological model is coupled to a forest model to better assess the influence of changing drivers to forests and the hydrological cycle

Remote measurement of flood runoff

To investigate flood peaks and volumes in torrents, a method is being developed which allows remote triggering of the discharge measurement. Images of the precipitation radar are used to determine the time of measurement.

Process-based runoff generation approach for hydrological models

In collaboration with Scherrer AG and GmbH Soilcom a new runoff module is generated for hydrological models. Spatially distributed process information from so-called runoff process maps, which are based on field recordings and geographical bases, will be integrated into the module.

DROUGHT CH

Droughts and heat waves are expected to become more frequent in Switzerland due to climate change. Droughts have major impacts on water resources, public health, ecosystems and consequently the economy. However, information about relevant economic and societal impacts and knowledge about adequate coping strategies are still lacking.

IFKIS Hydro Sihl

WSL develops and operates a probabilistic flood forecasting system for the pre-alpine catchment of the river Sihl. Floods can be detected early through a series of daily performed predictions.
