HIGHLY INSTRUMENTED BASIN/EXPERIMENTAL SITE 'BONIS – Locality Petrarella - Longobucco (CS) - Sila National Park (CS)

Assessing the impact of forest cover on the hydrological balance and surface runoff through: meteoclimatic and flow measurements, necessary for hydrological and forest modelling on a basin scale, dendro auxometric surveys of the forest stand and soil sampling aimed at determining the chemical and physical characteristics of the soil. The measurements carried out are useful for the sustainable management of forest resources. The results of the modelling make it possible to quantify the regrowth capacity of forest species in the forest also in the light of current climate change and thus to optimise silvicultural interventions.

At the Bonis Basin, there are:

• 2 weather stations, located at the basin closure, for measuring wind speed and direction, relative humidity, atmospheric pressure, precipitation, temperature and solar radiation.
• 1 reinforced concrete basin, located at the closing section of the basin, 15.40 m long, 7.70 m wide and 4.50 m deep, with a volume of 533.61 m3. The basin is equipped with a triangular weir for measuring the flow rate, known hydrometric level.
• 1 multi-parameter probe, placed in the basin at the basin closure section, to measure the hydrometric level, water temperature, conductivity, pH, dissolved oxygen and turbidity.
