Book Description
Excerpt from Land Drainage by Means of Pumps In constructing diversion ditches the experience of the Coal Creek District should be kept in mind and ample provision made for the deposition of silt before it reaches the diversion channel proper, otherwise the usefulness of the latter will be of very short duration. Even when silting basins are provided it Should be remembered that they will eventually become filled, and they should therefore be so located that other basins can later be constructed to receive the silt from the'same stream without incurring needless expense due to the improper location of the first basin. Local conditions will deter mine the plan to be followed, but the subject merits the most careful study. While in this country work of this nature is just starting, in England and Holland diversion ditches to prevent drainage water from flowing from higher lands onto lower areas, to the great damage of the latter, have been in systematic use for a long time. If the levees are properly constructed, as heretofore explained, the amount of seepage water passing under them is ordinarily so small as to be negligible, but if the soil or the subsoil of the district be very sandy, or if the levees have been carelessly constructed upon an improper foundation, the seepage may accumulate in sufficient quan tity to be troublesome. Ordinarily, if land near the levee is injured by seepage, the difficulty may be corrected by laying a line of tile parallel with the levee and 50 to 100 feet from the toe of the s10pe.

Modern Land Drainage
Author: Willem Vlotman
Publisher: CRC Press
ISBN: 1000042200
Category : Science
Languages : en
Pages : 509
Book Description
Modern Land Drainage 2nd edition is a fully revised and updated edition of the 2004 edition. Modern Land Drainage describes traditional drainage formulas (Hooghoudt, Kirkham, Donnan, Ernst, Glover-Dumm) for rainfed agriculture in the humid temperature zone. Significant parts are devoted to drainage for salinity control of irrigated land in (semi-) arid zones, and to drainage of rice land in the humid tropics. Institutional, management and maintenance aspects are extensively covered, as well as the mitigation of adverse impacts of drainage interventions on the environment. The latest computer applications for drainage design in the context of integrated water management are described (DRAINMOD, HEC, SWAP, etc.). Field surveys are executed by governments, with the aid of consultants, but rarely are the end stakeholders (i.e., farmers and general public) involved from inception to planning to execution of a drainage system. Yet, during the Operation, Management and Maintenance (OMM) phase of a water management system, they are expected to takeover, run, bear and be responsible for the costs of OMM. The book describes successful methodologies and processes to be followed for engagement of stakeholders at all levels, from government to farm, from minister to farmer, and, from beginning to end. The book covers all aspects needed for sustainable drainage. The latest survey methodologies with satellites and drones are suggested to assess cause and effect. Waterlogging and salinity are the effect of something caused most likely upstream of the drainage problem location. Hence treating the cause may be more cost-effective. Triple Bottom Line (social, environmental and financial considerations) and the water-food-energy nexus are an integral part of the drainage design process. Controlled drainage, i.e. the balance of removal and conservation of drainage water and minimising solute transport as low as reasonably achievable (ALARA principle) is extensively described. This work is intended for use both as a university level textbook and as a professional handbook; it is of particular value to professionals engaged in drainage development in the context of integrated water resources and river basin management, civil and agricultural engineers, government officials, university students and libraries.
