Hydrology

Delivery and processing of hydro-meteorological cantonal network. The sector offers as a service to verify the sizing of flow streams during development projects as well as the perimeter of the zone of danger to the phenomena of flooding, flood and debris flow.

Supply and data processing

On specific request (to be sent to idrologia@supsi.ch), data of the canton hydro meteorological network could be provided, which contain specific information about:
 

  • Precipitations
  • Air temperatures and other climatic parameters
  • Height and water flows
  • Water temperatures

In addition to these data, statistics, analysis for the evaluation of the curve of the flow duration and evaluation of Q3347 can be processed.

Processing height-flow relationship: Thanks to hydrometric measurements made with the aid of mathematical formulas we can elaborate the height-flow relation for the section under investigation.

Measurements of flow and levels in streams

Conductive measurements: Using the SalinoMADD instrument, we can measure the flow in materials with a maximum capacity of 1 m³ / s. It measures the flow rate on a measured distance. The presence of large pools of water and a reduced mixing from the point of entry of the salt to the point of measurement can affect the success of the measurement.

Measuring with small hydrometric reel

For fordable rivers there is a possibility to measure the flow rate using a hydrometric reel of small dimensions. It measures the section and different velocities to calculate the flow using specific software.

For rivers non fordable or with an extremely high flow rate a larger hydrometric reel is used. It needs a bridge or walkway where the instrument can be dropped.

To measure the level and the temperature of a river or the height of the water, we provide and install STS probes of pressure and temperature. The simple installation and low maintenance requirements make it an excellent solution for continuous measurements.
