dc.description.abstractA river steep of considerable length and height is situated on the right hand of the Værdal river at its mouth in the Trondheim fjord. Consisting og loose materials, an upper layer of sand and a lower one of sandy clay, the bank is disposed for falling down. Every now and then a large-scale slide occurs, as for instance in the years of 1925 and 1931. In 1932 further slides took place. In the month of March the river steep slid over a distance of 30 m. A few weeks later there was a slide of 6-7 000 m3, and towards the end of May same year the steep fell doen again for a length of 70 m with 10 000 m3 of sandy clay. Even in 1935 and 1938 similar falls of the steep have been reported. Besides these slides in the Southern part of the river steep, ordinary land- slips take place in the Northern part. 50 years ago, a landslip near the mouth of Ysse river wasted an area 80 m from the bank, at a length along the river of the same size, and 10 years later another landslip forced its way 40 m inland from the bank. Thus the Værdal river yearly wastes considerable areas of cultivated land bordering upon the river bank, and although the Nordland railway line is not yet threatened, lying 200 m from the bank, something will have to be done to limit the erosion of the river.
