National Conference on Management and Treatment of Contaminated Sediments


Book Description

This technology transfer meeting was held to disseminate info. on how to manage & treat contaminated sediments. 14 speakers presented various treatment options available for high- & low-end contaminated sites, & future research needs. Contaminated sediments is growing as an area of environmental concern, particularly when assessing ecological & public health risks. This report will be useful to individuals who are looking for information & techniques to treat contaminated sediments in rivers, harbors, lakes, &/or Superfund sites because of the associated ecological &/or public health risks or for navigational purposes. Illustrated.




Fundamentals of Ground Improvement Engineering


Book Description

Ground improvement has been one of the most dynamic and rapidly evolving areas of geotechnical engineering and construction over the past 40 years. The need to develop sites with marginal soils has made ground improvement an increasingly important core component of geotechnical engineering curricula. Fundamentals of Ground Improvement Engineering addresses the most effective and latest cutting-edge techniques for ground improvement. Key ground improvement methods are introduced that provide readers with a thorough understanding of the theory, design principles, and construction approaches that underpin each method. Major topics are compaction, permeation grouting, vibratory methods, soil mixing, stabilization and solidification, cutoff walls, dewatering, consolidation, geosynthetics, jet grouting, ground freezing, compaction grouting, and earth retention. The book is ideal for undergraduate and graduate-level university students, as well as practitioners seeking fundamental background in these techniques. The numerous problems, with worked examples, photographs, schematics, charts and graphs make it an excellent reference and teaching tool.







Urban Stormwater Management in the United States


Book Description

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
