The project proposes an accumulating copperhancing planning of landscape through scales to handle flooding and future water events in the riverways of the Norwegian mountain landscapes, based on the logic of water and topograhy. Through digital water accumulations and tracings of the valley and river in Hemsedal, the project challenge the act of separation of land and water. This seperation”line” has come into sharp focus during extreme floods, with proposals of walls, levees, natural defenses, land retirement schemes and recomendations for retreat.
