Available in PDF, EPUB and Kindle. Book excerpt: Diagnosis of drain failure at an early stage is extremely important to detect and correct the problem before crop losses become serious or topsoil is damaged. Subsurface drainage systems are expensive, long-term investments but they are important to modern mechanized agriculture. The farmer can protect his investment and assure continuing adequate performance of his drainage system by initiating an inspection and maintenance program as a regular part of his farming operations. Drain performance should be evaluated at least once a year on a regular basis and at any time there is a hint of a developing drainage problem.

Download or read book Pavement Subsurface Drainage Systems written by Barry Rodney Christopher and published by Transportation Research Board. This book was released on 1997 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to geologists; hydrologists; geotechnical, pavement, construction, and maintenance engineers; and researchers. State department of transportation (DOT) program managers and administrators will also find it of interest. The synthesis describes the current state of the practice for the design, construction, and maintenance of pavement subsurface drainage systems. It provides information on the positive effects of good subsurface drainage and the negative effects of poor subsurface drainage on pavement surfaces. This report of the Transportation Research Board presents data obtained from a review of the literature and a survey of the state DOTs. It is a supplemental update to NCHRP Synthesis of Highway Practice 96, Pavement Subsurface Drainage Systems (1982). The synthesis provides a supplement to design issues not found in Synthesis 96, but faced by current designers, e.g., type and quality of aggregate, compaction requirements for open-graded aggregates, asphalt and cement binders, and use of geosynthetics. In addition, it describes the effects of design, construction, and maintenance decisions on the performance of pavement subsurface drainage systems.

Download or read book Materials for Subsurface Land Drainage Systems written by L. C. P. M. Stuyt and published by Food & Agriculture Org.. This book was released on 2005 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable subsurface drainage systems for groundwater table and salinity control are needed to maintain or enhance the productivity of irrigated lands and to contribute to the rural development of lowlands in the humid tropic. This publication presents guidelines to assess the need for envelopes and for the selection of appropriate materials (i.e. pipes and envelopes) for the proper and lasting performance of subsurface drainage systems. In addition, it also contains guidelines for adequate installation and maintenance of drainage materials as well as the required specifications and standards of such materials, which may be used in tender documents for implementation of subsurface drainage works. Practical guidelines for the implementation of laboratory and field investigations to evaluate the performance of drainage materials have also been included.--Publisher's description.
