Download or read book Field Evaluation of the Long term Performance of Geocomposite Sheet Drains written by James Alan McKean and published by . This book was released on 2000 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long-term performance of geocomposite sheet drains were monitored at three sites by measuring the effect of the drains on site groundwater hydrology during peak groundwater events. The study is on-going with a maximum record of 14 years at one site in the southern Sierra Nevada Range, CA.‍?Over a 3-year period, the drain at one site produced as much as 100 liters per minute with no rise in the water table just down gradient from the drain. The peak hydraulic gradient toward this drain consistently reaches 0.66 to 0.73 during major rainstorms and returns to a S2base levelS3 of 0.45 to 0.50 within 10 days after a storm peak.‍?At a second site, the drain flowed up to 15 liters per minute with no water table rise in a retaining wall fill down gradient from the drain. Performance of this drain was consistently favorable over a 14-year period with no deterioration. Limited data suggest that the drain discharge (liters per minute) is proportional to about 13 times the hydraulic gradient toward the drain.‍?At a third site, drain performance is limited by construction problems. A collapsed trench wall during drain placement caused an uneven drain slope toward the outlet. This is a common problem of trench drains at sites with a high water table. The problem could be greatly mitigated by returning to one of the pioneering geocomposite drain designs, the Eljen Drain, in which vertical sections of the drain are completely independent units that can be immediately dropped into a trench behind the excavator. Despite the construction problems, the drain is partially dewatering the road prism just down gradient, as seen by approximately 1.2 meters of groundwater drawdown beneath the road.

Download or read book Geosynthetics Leading the Way to a Resilient Planet written by Giovanni Biondi and published by CRC Press. This book was released on 2023-09-15 with total page 2826 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the 12th International Conference on Geosynthetics (12 ICG), held in Roma, Italy, 17-21 September 2023. About 750 Authors - Academics, Researchers, Students, Practitioners, Contractors and Manufacturers – contributed to the peer-reviewed papers of this volume, which includes the Giroud lecture, the Bathurst lecture, the Rowe lecture, four keynote lectures and 296 technical papers. The content of these proceedings illustrates the sustainable use of geosynthetics in a variety of innovative as well as consolidated applications. After the sustainability implications in the correct use of geosynthetics, the ability to overcome the natural events effects, often related to the climate change, and to adequately afford the human activities (as the increase of pollution) forced to refer to a new keyword: Resiliency. The 12 ICG intends to become the base for the next step, hence the conference theme is 'Geosynthetics, Leading the Way to a Resilient Planet'. The conference topics, through general and parallel sessions, invited presentations and keynote lectures, address the most recent developments in geosynthetic engineering, and stimulate fruitful technical and scientific interaction among academicians, professionals, manufacturers, students. The 12 ICG proceedings contain a wealth of information that could be useful for researchers, practitioners and all those working in the broad, innovative and dynamic field of geosynthetics.

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.
