SAIH-Segura-Infrastructure

Instrumentation

Bearing in mind the variables required for distinguishing the hydrological phenomena to be analyzed, evaluated and, where appropriate, managed, the most suitable sensors for this purpose have been defined and selected. Accordingly, rainfall has been determined as a natural inflow to the basin, and a pluviometric network has been installed for measuring it. For calculating the volumes of surface waters: in the cases of dammed water and circulating water, level sensors have been installed in reservoirs, as well as level and/or speed sensors in different characteristic sections of the natural drainage network, beds and in the exploitation network, the latter including its hydraulic infrastructures, in beds and in canals, together with their respective bathymetries and rating curves, where appropriate.

On the other hand, apart from floodgate opening measurement sensors for calculating outlet flows, flow meters in pumping stations and level alarms in beds have also been installed. All the sensors form the SAIH telemetry network.
