Environment
Bayelva is situated on Brøggerhalvøya, due west of Ny-Ålesund. The catchment area is 30.9 km² of which 54 % is covered by the glaciers Austre Brøggerbreen and Vestre Brøggerbreen. In 1988 NVE initiated the discharge measurements and the river profile of Bayelva was stabilised by a large compound crump weir, designed and built by NVE. The cost was about 1 million Norwegian 1988-kroner. As the river profile is constantly changing there followed several problems, mainly due to the large amounts of sediment and ice build-up, but most were solved the following year.
The main problems with the runoff measurements are connected to ice and snow blocking the weir at the beginning of the snowmelt season (Fig. 14), leading to errors in calculation of river discharge. This is corrected for as far as possible, but the resulting accuracy is not known precisely.
