- Ljubljanica River experimental catchment monitoring system
The Ljubljanica River catchment is an example of
a hydrologically
highly heterogeneous catchment (karstic hydrogeological
characteristics, torrential characteristics, lowland Ljubljanica
River marshes). Hydrological and hydraulic experimental
monitoring system covers several sub-catchments of different
sizes. The monitoring system consists of the field equipment
owned by: University of Ljubljana, Faculty of Civil and
Geodetic Engineering and the Slovenian Environmental Agency (ARSO).
The main Ljubljanica River experimental catchment is equipped with
18 rain gauge stations (Figure 1) and 17 water stations in the
lower section of the river (Figure 2). 3 water stations have
online connection. At 3 locations, dissolved oxygen (DO)
concentrations are measured by automatic DO sensor.
Figure 1: Rain gauge stations at the
Ljubljanica River experimental catchment (the red rectangle
indicates the area shown in Figure 2.)
Figure 2: Water stations in the lower (lowland)
part of the Ljubljanica River.
The monitoring system at the Gradaščica River (tributary of the Ljubljanica River) is shown in Figure 3. The rainfall is recorded at 10 tipping bucket rain gauges, one meteorological station and 1 disdrometer, stream discharge at 3 waters stations. At two water stations, a multi parameter water quality sonde can be installed. The probe is equipped with a temperature, pH, electrical conductivity, nitrate, and turbidity sensor.
