Hydrology
The knowledge of the hydrological cycle allows you to effectively manage water resources, predict full disastrous, optimize the use of water in energy production and reduce landslides and soil erosion.

The hydrology sector, together with the hydrogeological - limnology one, provides integrated studies and assessments on the state of water resources. The developed skills are offered to the public through research, service, training and dissemination activities, which promote a holistic vision of the hydrological cycle and the problems that can threaten.

Among the research we report the development and application of models for hazard zonation: it is part of the models developed directly at the institute, affecting the river floods and debris flows. The research projects are focused on the monitoring of drought in some Caribbean islands, through tools that allow the analysis of rainfall data and provision of a mapping service WebGis.
 

Hydrological monitoring

The sector manages the hydro-meteorological network of the Canton Ticino due to a mandate of the cantonal administration: it collects stores and analyzes rainfall data, climate, height, flow rate and water temperature for more than 30 years. In total there are more than 50 stations spread over the whole territory, to which those for monitoring of aquifers, managed by the group of hydrogeology can be added. Since 1979, the Hydrological Yearbook of the Canton Ticino is available and now downloadable from the website of the institute.

Minimum flows

The sector is responsible for the determination and control of minimum flows residual to ensure the protection of ecosystems and the application of the Law on water protection. Advises the administration cantonal licenses for taking specimens public water surface, the group provides also services in setting measurement stations and hydrometric measurements.

Hydrological modeling

In case of weather warning, the sector provides a prediction of the water level of Lake Maggiore and its main tributaries for civil protection purposes, using a self-developed hydrological model, in operation for more than 10 years and on several occasions it has demonstrated its reliability.

Conceptual models have also been developed for the optimization of hydropower production and management of dams in case of intense events, so as many other models for specific research projects.

Areas exposed to natural hazards

The sector offers as a service the estimate of flow streams in the environment of development projects, as well as the perimeter of the zone of danger to the phenomena of river flooding, inundations and debris flow.

Reearch

Among research activities, we report the development and application of models for hazard zonation: it is part of the models directly developed at IST, affecting the river floods and debris flows. The research projects are focused on the monitoring of droughts on some Caribbean islands and hydrological modeling for flood forecasting, evaluation of the effectiveness of dams in flood reduction and optimization of hydropower production.
