Pariatamby, A: Landfill cover systems modelling for Tropical

Leachate management technology has evolved over time, varying with the type and complexity of leachate. The technologies in temperate countries may not satisfactorily operate under tropical conditions. It is important to prevent the volume of leachate generated to reduce the cost of treatment and to minimize pollution. Leacheate treatment is expensive and the method of treatment may be ineffective. This book discussed various landfill cover options to provide an efficient technology to minimise the volume of leacheate generated. The models described are based on VHELP software which incorporates the latest technology for volume reduction. The contents include an overview of the final cover systems, and factors affecting volume of leachate. VHELP demonstrates the various options available for landfill cover layer materials. The book is expected to bridge the gap between developed and underdeveloped countries, in terms of the principles involved in leachate management. The inclusion of local case studies enhanced the Asian flavour of the book and makes it an important reference for university students, and practicing professionals.
