Available in PDF, EPUB and Kindle. Book excerpt: This fully updated third edition of the classic text, widely cited as the most important and useful book for health engineering and disease prevention, describes infectious diseases in tropical and developing countries, and the effective measures that may be used against them. The infections described include the diarrhoeal diseases, the common gut worms, Guinea worm, schistosomiasis, malaria, Bancroftian filariasis and other mosquito-borne infections. The environmental interventions that receive most attention are domestic water supplies and improved excreta disposal. Appropriate technology for these interventions, and also their impact on infectious diseases, are documented in detail. This third edition includes new sections on arsenic in groundwater supplies and arsenic removal technologies, and new material in most chapters, including water supplies in developing countries and surface water drainage.

Download or read book Root zone salinity management using fractional skimming wells with pressurized Irrigation: proceedings of the Year-End Seminar 2001 written by Muhammad Siddique Shafique and published by IWMI. This book was released on with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the short water supply environment of Pakistan, fanners try to minimize the gap between demand and supply of canal water by extracting groundwater for irrigation purposes. However, saline groundwater upconing may occur in response to fresh groundwater withdrawals from unconfined aquifer underlain by salty groundwater. Skimming well technology can help in control1ing this upconing phenomenon. However, in most cases, the small discharges of such wells cannot be efficiently applied on surface irrigated croplands. Pressurized irrigation systems use smal1 discharge effectively, but the cost and availability of equipment in the local market are the constraints. Root zone salinity is also expected to increase if this skimmed groundwater is used for irrigation purposes, particularly in the absence of proper salinity management practices. To address these issues, International Water Management Institute (lWMI), Water Resource Research Institute (WRRI) and Mona Reclamation Experimental Project (MREP) collaborated to undertake an applied research project on Root Zone Salinity Management Using Fractional Skimming Wells with Pressurized Irrigation. This project was started in March 1999 and concluded in June 2003. The National Drainage Program (NDP), Research Component -WAPDA funded this project

Download or read book Performance Analysis of On-demand Pressurized Irrigation Systems written by Nicola Lamaddalena and published by Food & Agriculture Org.. This book was released on 2000 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the strong competition that is arising for water resources the modernisation of irrigation systems is becoming a critical issue. One of the alternatives to modernisation is the use of pressurised systems to replace part of the existing networks. This publication analyses the performance of pressurised irrigation systems operating on demand, and provides revised criteria for the design of such irrigation networks. For this purpose, new approaches and a computer program have been developed. The program has been tested in several field situations in the Mediterranean Basin and has demonstrated its usefulness not only by quickly identifying weak points in irrigation networks but also by identifying the power requirements of pumping stations needed to satisfy varying demand situations.
