TRANSPORTING METHOD OF RIVER WATER IN THE SEA

PROBLEM TO BE SOLVED: To change a desert land to a cultivated land by transporting part of river water flowing in a high-rain area to a desert country for a long distance through a cylindrical water feed pipe submerged in the sea. SOLUTION: A dam for preventing sea water from mixing and water intake is provided in a river on the upper stream from the estuary, a pool 5 served also as a settling tank on a high place nearby the dam, and water taken from a water intake port by a storage pump is fed to the pool 5. Next a water feed pipe 6 is connected to the pool 5, and the river water flows in the pipe by head. Next the pipe 6 arrives in the sea through the pipe provided in the river, and sunk so as to contact with the sea bottom 8. The pipe in the sea is extended to a water receiving country at the depth of about 100 m, the pipe arriving on the coast of the water receiving country is again extended to the land while contacting with the sea bottom 8 to be connected to a pool 9 on the land, and water is distributed from the pool 9 to the destination of the water receiving country. Further, the wall thickness of the water feed pipe is set so that the buoyancy and the gravity of the water feed pipe are balanced with each other in the sea water. Hereby, a desert area can be planted with trees and the climate can be made mild.
