• Sommario/riassunto: Question: How can I best evaluate the environmental impact and find the risk of water pollution from wastewater disposal? Answer: This book shows you the way! In a unique and comprehensive manner, questions of risk and reliability in water quality are analyzed. And more than that: The author also develops a methodology to evaluate the environmental impact of wastewater disposal on rivers, groundwater and coastal areas.Major topics covered include: fuzzy set theory for engineering risk analysis/ uncertainty analysis of water quantity and quality data/ stochastic and fuzzy simula
