タイ国における地下水開発の構想とそれに伴なう土質改良について

Abstract

In Thailand, especially in the Central Plain area, there is a great lack of water in the dry season, despite the large amounts of rain which fall during the rainy season. This is due to the fact that there is virtually no subsurface storage of water because of the inherent soil conditions which encourage rapid run-off. This paper deals only with the mechanical problem of water storage. In order to store water underground, the subsurface soil must be treated physically (mechanically) and chemically. The construction of underground dams and connecting systems of underground channels is proposed as a mechanical solution to the problem, to preserve ground water and to block run-off. The chemical problems which necessitate treating the subsoil to ensure the eventual utilizability of the stored water are indicated, but not here otherwise explored.
