This book will include simplified, yet comprehensive details of geotechnical engineering issues that are important to environmental engineers. It will explain how to analyze and interpret numerous practical geotechnical engineering problems. It will differ from other geotechnical engineering books in that it will be written specifically for environmental engineers, and deal less with aspects that apply more to civil engineers. Soil mechanics and hydraulic theories will be simplified and supported with extensive numerical problems pertinent to environmental engineering applications. It will also include several environmental engineering case studies throughout, such as landfill design, etc.
