12-Vertical drainage for reclamation of saline land.

Abstract

Well drainage is an alternative method to gravity drainage. A brief account of the problems of salty soils, their origin, occurrence, and reclamation are given. Some theoritical and practical aspects of well drainage are discussed in this paper. Factors affecting the feasibility lf drainage wells are outlined. Its adoptability and limitations, the problem of interference in multiple well system, types of drainage wells, spacing and drainage criteria, and design considerations are described. Recent approaches for design of drainage well system are presented.
