  • - A Guide to Integrating Plant, Soil, and Water Relationships for Drainage of Irrigated Lands
    av Bureau of Reclamation & U S Department of the Interior

    This manual contains the engineering tools and concepts that have proven useful in planning, constructing, and maintaining drainage systems for successful long-term irrigation projects. The manual is not a textbook. Mathematical and experimental development of the engineering tools has generally not been included. Indeed, not even all the innovative ways to use the tools are included. The manual provides drainage engineers a ready reference and guide for making accurate estimates of drainage requirements. Design and construction criteria, if followed with reason, will result in reliable drainage systems for irrigated areas.All the methods and techniques covered in the manual have proven to be very satisfactory through observed field conditions on irrigated lands throughout the world. Some methods have a more elegant development and basis in science than others, but all have been designed to solve practical problems in the field.

  • - A Guide to the Use of Soils as Foundations and as Construction Materials for Hydraulic Structures
    av Bureau of Reclamation & U S Department of the Interior
    491,99

    This manual provides technical information on the field and laboratory investigations and construction control of soils used as foundations and materials for dams, canals, and many other types of structures. It contains both standardized procedures that have been found desirable for securing uniform results, and general guidelines intended to assist but not to substitute for engineering judgment.The Earth Manual represents the joint efforts of many engineers and technicians over a period of many years.
