Available in PDF, EPUB and Kindle. Book excerpt: El riego se emplea, en los climas lluviosos, no solo para suplir la falta de lluvia en ciertas epocas (riego compensador), sino con otros fines, tales como suministrar elementos nutritivos a las plantas, regularizar la temperatura del medio, etc. Por esto los primeros datos que se publicaron sobre los volumenes de agua necessarios para el riego reflejaban cantidades elevadisimas, muy superiores como despues se ha visto a las verdaderas necesidades de las plantas. En los climas mas o menos aridos su mision es, excepto en determinados casos, solo compensadora o integral, proporcionando a la planta el agua que precisa, que ensu mayor parte cumple como funcion la de mantener la temperatura de la planta dentro del optimo termico correspondiente al periodo de crecimiento; la planta devuelve el agua a la atmosfera por la funcion traspiradora.

Download or read book Biological Wastewater Treatment written by Mogens Henze and published by IWA Publishing (International Water Assoc). This book was released on 1881 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.

Download or read book Tourism and Water written by Stefan Gössling and published by Channel View Publications. This book was released on 2015 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic and comprehensive guide to the current state of knowledge on tourism and water. It is the first book to thoroughly examine the interrelationships of tourism and water use based on global, regional and business perspectives. Its assessment of tourism's global impact along with its overviews of sectoral and management approaches will provide a benchmark by which the water sustainability of tourism will be measured for years to come. In making a clear case for greater awareness and enhanced water management in the tourism sector, it is hoped that the book will contribute to the wise and sustainable use of this critical resource. The book is interdisciplinary in coverage and international in scope. It is designed as essential reading for not only students of tourism but also practitioners.

This book was released on 2018-06-27 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: National information needs on forests have grown considerably in recent years, evolving from forest area and growing stock information to key aspects of sustainable forest management, such as the role of forests in the conservation of biodiversity and the provision of other ecosystem services. More recently, information on changes in carbon stocks, socio-economic aspects including the contribution to livelihoods and poverty reduction, governance and broader land use issues has become critical for national planning.
