This book is the result of a long-term co-operative research and professional development programme between the Instituto de Investigaciones Electricas (IIE), Mexico, and the University of Salford, UK. It provides the design basis for the fabrication of small and large scale commercial absorption heat pump systems, and includes a comprehensive treatment of the economics of heat pump systems. It charts the development of heat pump technology from theoretical principles to the operation of practical systems for the purification of water, both for human consumption and a wide variety of industrial purposes.
Modules to Water Access in a Changing World addresses topical issues in water supply.The book integrates detailed information on key access indices, quality, economics of demand and supply, socio-economic variables, health and sustainable development in a typical rural environment. The generation of the RTWC model and adoption of the threshold constant (K)for quantification and delineation of surplus, deficit and balance zones; water quality testing for source protection, health and food security contributes valuable data to the world of science. This book will be of utmost interest to policy makers in the water industry, geographers, hydrologists, researchers and environmental practitioners.
Get the most up-to-date and comprehensive guide to watershed analysis and management. <p> In <B>Watersheds: Processes, Assessment, and Management</B>, author Paul DeBarry covers aspects of watershed physical processes such as assessing, classifying, and evaluating a watershed; using GIS models for watershed assessment; and effectively planning for future use and demands. He covers precipitation, ecology, geology, soils, geomorphology, hydrogeology, hydrology, water quality, hydraulics, GIS, data collection, planning, and management. And he takes you beyond theory so you learn to apply planning, management, GIS, and hydrologic engineering principles in real-world watershed management. <p> This concise reference manual is ideal whether you're a scientist, biologist, geologist, engineer, planner, administrator, part of a citizens group, or a practitioner seeking to identify what is important in the watershed being studied.
