Summary: | Description of the embankment breach test site The large scale embankment test site is located in the middle of Norway in Nordland County and the Hemnes Municipality, near the town of Mo i Rana. The location is shown in Figure 1 On the detailed map the Røssvatn Reservoir and Røssåga River flowing north and into Sørfjorden is seen. Figure 2 shows a picture of the test area with the Røssvassdammen Dam and about 1000 m of the Røssåga River. The test site is located as indicated on the picture, about 600 m downstream of the Røssvassdammen Dam. The location downstream of the Røssvassdammen Dam makes it possible to control the inflow to the reservoir behind the test dam by regulating one or more of the three flood gates. Røssvatn is the intake reservoir for Upper Røssåga power plant which outlets into Stormyr-bassenget reservoir at an elevation of 247.9. The 8500 m reach of the River Røssåga in between is normally dry (local inflow only) and floods during spring only occasionally. Stormyrbassenget Reservoir is the intake for Lower Røssåga power plant with outlet in Røssåga River at Korgen. The 12000 m reach of the River Røssåga in between is also normally dry (local inflow only) and only floods occasionally during the spring. |
