In the spring,when the ice breaks up, the water level gauge gets damaged due to ice floes. Oneconsequence of this phenomenon is that the engine operators of the power plantrepeatedly have to replace the broken gauge with new ones. Another consequence isthat the quality of the measurements of the water level is low while the gauge is inbad condition.To explore the possibilities of replacing the gauge with a camera surveillance systemboth the technical and sociotechnical conditions were investigated. From a technicalpoint of view there was no problem with the project and a program that calculatesthe water level in the dam was created in MATLAB. From a sociotechnical point ifview on the other hand, the project could not be carried out. Due to the waterdecree, the water level gauges could not be replaced. Therefore, no camerasurveillance system was implemented.Handledare: Magnus Eriksson, Vattenfall ABÄmnesgranskare: Ewert BengtssonExaminator: Elisabet AndrésdóttirISSN: 1650-8319, UPTEC STS07 016
