- Ljubljanica River experimental catchment monitoring system


The Ljubljanica River catchment is an example of hydrologically highly heterogeneous catchment (karstic hydrogeological characteristics, torrential characteristics, lowland Ljubljanica River moor area). 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 Environmental Agency of the Republic of Slovenia (ARSO).

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.

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 sonde is equipped with temperature, pH, electrical conductivity, nitrate and turbidity sensor.
