Lakescapes, preserving agriculture

students: Alexandre Roulin, George Sarmaniotis

overview 1

The high level of the water table in the Linth Valley in Switzerland and Its consequences the basic issue this project deals with. The main economical activity in the area is agriculture and is sustained through intensive drainage of the fields due to the fact that the water table is close or some times above the ground level, depending on the period of the year. The result of this action is the shrinking of the ground, which in the very near future will lead to the complete sinking of the ground surface turning the grass fields into swamps.

In order to prevent the above course and preserve agriculture as a main activity in the area, this project focuses on a solution that proposes two main actions connected topologically and economically in an balanced way.  The first action is the digging of the most problematic areas, as far as concern  the proximity  to water table, and the second is the use of the digging material to fill the less endangered parts of the valley, neighboring the previous areas, in order to be secured without the need of intensive drainage. The result of those two actions will be the raise of the ground level by creating lakes.

FROM ANALYSIS TO DESIGN 

Testing the microtopography tool on sand model

Simulation of the water table impact based on color coding. The blue color range charters the areas where the water table covers the ground surface. Dark blue means deeper flooded areas and light blue shallower. The green color range charters ground surface in proximity to the water table. Dark green means bigger distance from the water table “safer areas “, while light green means smaller distance from the water table “endangered areas”
