Although knowledge and understanding of the causes, nature and harmful effects of excess water and salts in the root zone have tremendously increased over the last few decades, yet land and water degradation is causing decline in the productivity of these resources and also impacting the environment. Realizing that the only solution to these problems is through land drainage this book has been written to add to the scanty literature on this subject.
