dams and tunnels
The Dams and Tunnel Songavatnet or Songa Lake is one of some lakes in Vinje district which generate Tokke hydropower scheme. The rockfill dam at Songa was the largeset in Norway at the time it was built, measuring 40 meters in height and around 1000 metres in length. This provide recreational opportunity for people around the area and visitors.It has drop height and potential for water flow regulation as seen to be suitable location for a hydropower scheme in Southern Norway. Tunnel underneath the dam has very important role in hydropowerplant system. Turbines, generators, wires, and other mechanical and techinal stuff exist in here. The space below surface, the darkness, the isolated place from outside doesn’t mean than it has less activities. Substantively, Inside the tunnel has great contribution in transforming the stillness of the water to become a powerful electricity.
At the Songa dam, we see a beautiful piece of man made structure that seems very natural. The dam is built by rocks instead of concrete or other processed material. Sun light, water, earth, woods, and the dam all come together. So, here I can feel the humbleness of human intervention in nature.
the concept
dams and tunnels
In the tunnel, we find substitution from elements outside. Lamps lights will guide us, we find moss instead of trees, and water everywhere. Water, the delicate yet powerful source of energy is able to seep through rocks. It grows moss. It runs inside gigantic pipes that emerge from the wall of the tunnel, and it turns the big turbines which eventually produce electricity.
These pictures show how light can illuminate tunnels. Light can also create beautiful installa-
Water is a substance that brings life to every creatures in the universe. It is able to penetrate solid rock, and to create moss. Water drips cointaining minerals may seep through the rock, and gradually form a precipitation.

the tunnel. At the end of the tunnel, we are suprised surrounding our heads instead of sky, but we can still by the spaciousness of the turbine hall. find water that penetrates through massive rock. As we proceed the atmosphere changes gradually, lights fades, pressure, water runs differently.
Water seems delicate. But in here, we will eventually see that water has the ability to spin the huge turbine and produce electricity afterwards.
the design
The intensity of light is different from what we see at the beginning and far inside the tunnel. Somehow we can use other artificial device to enlight the tunnel. Light is the main element creating the interesting instalations at the beginning of the tunnel
section
At this point, the light slowly faded, oxygen more scarce, and the dampness gets higher. At the same time, water comes through the rockand create moss.
We are now has reached the deepest sequence of the tunnel. Here we

How can the man made and natural forms co-exists without disrupting each other.
