The ClimateBasic programme gathers and accumulates data describing the climatological and hydrological conditions in Kobbefjord. Data are measured by two automatic climate stations (C1 and C2), two automatic hydrometric stations (H1 and H2) and three diver stations (H3, H4 and H5).
The two climate stations are placed next to each other to ensure data continuity. After a few corrections during 2008 all the stations are working correctly now monitoring a total of 16 climate parameters.
In Kobbefjord measurement of the water level and manual discharge measurements at H1 started in 2006 and at H2, H3 and H4 in 2007. Manual measurements of discharge were continued at H1, H3 and H4 in 2008. In 2008 measurement of the water level and manual discharge measurements at H5 were added to the programme. H1 and H2 are measuring throughout the year, while measurements at H3, H4 and H5 starts up in early spring when the rivers are free of snow and ice, and ends in late fall before the rivers freezes.
The stage-discharge relation (Q/h relation) established for H1 after season 2007 has been re-evaluated on the basis of measurements made in 2008, although there still is a lack of measurements at high water level. For H2, H3, H4 and H5 there still is a lack of discharge measurements to establish reliable Q/h-relations. For H1, which is placed at the main river in Kobbefjord, the total discharge during the hydrological year from 1 October 2007 to 30 September 2008 was 30.1 million m3. The peak discharge in 2008 was recorded on 14 June caused by a combination of spring snow melt and precipitation.
