Abstract
Excerpts from the Preface: Many publications have been written throughout the world on drainage research and its applications. Since 1955, materials such as plastics have opened up new fields of drainage and seepage control; machinery has been developed for all types of drainage materials; new methods have been used to speed up drainage; improved practices have been developed for irrigation and salinity control; and better maintenance has helped solve some of the problems of drainage in the field. Moreover, research in related areas such as soil physics, hydrology, and hydraulics has created new Instruments and techniques which have improved drainage procedures. To keep up with the demand for Information on both surface and subsurface drainage, this annotated bibliography has been compiled. Hopefully, it will prove useful as a ready reference to all those interested in drainage and its many aspects such as history, economics, needs, designs, applications, use, and problems.
