Formålet med undersøkelsene var å finne potensialet for uttak av grunnvarme. Det er foretatt georadarmålinger, boringer, og analyser av boreprøver. I ni undersøkelsesbrønner er det målt temperaturer og grunnvannsnivå på 5, 10 og 20 meter dyp. Målingene har blitt foretatt fra 3.mai til 23. november 2007. Registrering av fluktuasjoner i vassdraget rundt akviferen har blitt foretatt i samme periode. Dataene har blitt brukt til å utvikle en sedimentologisk modell og til å bygge en tre dimensjonal grunnvannsmodell for simulering av grunnvannsstrømning og varmestrøm. Det er brukt finite element modellen FEflow 5.3. Det er gode samsvar mellom observerte og simulerte verdier. For vurdering av uttakspotensialet er det utarbeiddet et transmissivitetskart og et temperatursenkningskart for 15 til 20 meter der temperaturen er stabil i området ved 7-9 °C. Resultatene viser at det er mulighet for store pumpekapasiteter, at det er optimale temperaturer for bruk av grunnvarme. Det er gjort et kart som viser grunnvarmepotensialet (kW) i ulike områder. ENGLISH SUMMARY: In this master thesis groundwater surveys in an aquifer in Seljord, Telemark, Norway have been done. The purpose of this work is to find the potential for utilization of ground heat from the aquifer. Field surveys have been ground penetrating radar, drillings and sediment analysis. Nine monitoring multilevel wells have been established and groundwater temperatures and heads from 5, 10 and 20 meter depth have been recorded. Temperatures and water level from surrounding rivers and lakes were also recorded. To obtain this a sedimentological model and a 3D groundwater flow and heat flow model have been made. The finite element model FEflow 5.3 was used. There is a good correspondence between observed and simulated results. To evaluate the groundwater heat potential, there are made maps of transmissivity and possible temperature lowering and pumping capacity from depth of 15-20 meter, where the temperatures are stable at 7-9 °C. The results show possibilities for huge pump capacities and optimal groundwater temperatures for use of the groundwater heat. It is made a map that shows the potential of ground heat in different areas.

As seen from the college, this way of administering the students' work appears powerful. After briefly having described the "Telemark Model", the paper concludes by reporting positive academic feedback from the U.S.A. in addition to present the students' opinion about this way of conducting cooperative learning. It has been found that students at large find project work in groups timeconsuming but rewarding. Their positive attitude towards cooperative learnng becomes more clearly pronounced as they advance from freshmen to seniors and Graduates. The latters, who are seing the whole proeess retrospectively, are reported to find the process of a 3-year's cooperative learning program useful to their daily work.

An automatic small film camera with an autodynamic flash and extra equipment for microphotography is necessary. The camera's electronics determine the light intensity from the flash.

Important changes in technology and society, including the educational system, began and nourished the work. The preparation process formally commenced in August 1995 and has included educational, psychological, tactical and organisational means to attain the goal. Results from tests given to 36 entering freshmen of this class are presented and discussed in the paper. Project organisation and test results indicate that today's vocational schools may represent a future sector for the recruitment of new students into the engineering profession.
