Book excerpt: French Abstract: Dans le socle granito-gneissique du bassin du Zou, l'accès à l'eau potable est principalement assuré par les aquifères de fractures. Dans l'optique de faciliter l'implantation des forages, cette étude d'une part a établi la carte de fractures et d'autre part évalué le potentiel en eau des nappes dans cette partie du Bénin. D'abord les filtres directionnels Sobel sont utilisés pour extraire une représentation du réseau de fracture. De ces données, trois familles de directions majoritaires sont identifiées : N180-N30, N90-N110 et N60-N70. D'autres minoritaires notamment N130-N140 affectent aussi ces formations cristalline et cristallophyllienne. Les longueurs de fractures se concentrent dans un intervalle de 1 à 2 km (65 %) cependant les extrêmes inférieurs à 1 km et supérieur à 2 km donnent respectivement 12,7 % et 22 % de segments. Cet ensemble de direction révèle une densité de fractures moyenne de 2,4 km/km2 avec des zones telles que le Sud de Iroukou de faible valeur (0,8 km/km2) et Dassa de forte densité (5,2 ± 0,9 km/km2). Ces résultats sont utiles à l'implantation car plus de 60 % des forages situés à moins de 200 m d'une fracture identifiée est positif. De plus, d'autres cartes telles que l'épaisseur d'altération, la lithologie, le drainage, la hauteur de pluie et la pente sont confrontées à la densité de fracture à l'aide de l'analyse multicritère de décision. Selon la contribution de chaque carte à la disponibilité des eaux souterraines, les poids sont respectivement : 0,158 ; 0,074 ; 0,126 ; 0,302 ; 0,065 et 0,275. Il ressort des analyses que le bassin est caractérisé par un potentiel très faible (9,2 %) à faible (18 %) vers Djidja, Gangan et Glazoué, modéré (24,7 %) dans les environs de Zoudji et Yagbo et bon (27,5 %) à très bon (20,6 %) vers Savalou. Le potentiel en eau de ces blocs d'aquifères peut varier de façon significative même à l'échelle locale. Malgré les contraintes, ces ressources sont essentielles à l'atteinte de l'Objectif de Développement Durable 6 dans le bassin, bien entendu après une étude approfondie des aquifères afin de garantir l'accès à l'eau potable des populations et la pérennité des forages.

Available in PDF, EPUB and Kindle. Book excerpt: Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources. The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies. The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Water is the elixir of life and is crucial for sustainable development. Earlier, it was considered to be a limitless or at least a fully renewable natural resource. During the past 20 years, however, there has been tremendous pressure on this precious natural resource mainly due to rapid urbanization, industrialization and the increase in the human population. Together, these have resulted in increasing demand for irrigation, industrial, and household purposes to meet supply-chain requirements. Keeping in mind the scarcity of available water resources in the near future and its impending threats, it has become imperative on the part of scientists in hydrology and allied disciplines such as geography, landscape planning, sustainability science etc. Regional planners and supply chain management experts also must be involved in studying the spatial and temporal nature of the growing demand for water and the future availability for its judicial use and sustainable management. A primary intent of the book is to provide comprehensive scientific knowledge base on water resource management and sustainability. It covers geo-engineering and scientific problems, case studies, and sustainable solutions in the water resources management domain. Additionally and of equal importance, the chapters of the book provide in-depth coverage on water resource vulnerability, water quality, wastewater treatment, application of remote sensing and geographical information systems hydrological modeling and harvesting, climate variability and runoff, sediment discharge and irrigation planning, community participation in water governance, internet of things and machine learning applications for sustainable water resources management. This practical, state-of-the-art reference book is a valuable resource for students, researchers, scientists, policymakers, spatio-temporal designers of water resource systems, various stake holders interested in hydro-climatology and sustainable water resources management.

Book excerpt: In 1947, British India-the part of South Asia that is today's India, Pakistan, and Bangladesh-emerged from the colonial era with the world's largest centrally managed canal irrigation infrastructure. However, as vividly illustrated by Tushaar Shah, the orderly irrigation economy that saved millions of rural poor from droughts and famines is now a vast atomistic system of widely dispersed tube-wells that are drawing groundwater without permits or hindrances. Taming the Anarchy is about the development of this chaos and the prospects to bring it under control. It is about both the massive benefit that the irrigation economy has created and the ill-fare it threatens through depleted aquifers and pollution. Tushaar Shah brings exceptional insight into a socio-ecological phenomenon that has befuddled scientists and policymakers alike. In systematic fashion, he investigates the forces behind the transformation of South Asian irrigation and considers its social, economic, and ecological impacts. He considers what is unique to South Asia and what is in common with other developing regions. He argues that, without effective governance, the resulting groundwater stress threatens the sustenance of the agrarian system and therefore the well being of the nearly one and a half billion people who live in South Asia. Yet, finding solutions is a formidable challenge. The way forward in the short run, Shah suggests, lies in indirect, adaptive strategies that change the conduct of water users. From antiquity until the 1960‘s, agricultural water management in South Asia was predominantly the affair of village communities and/or the state. Today, the region depends on irrigation from some 25 million individually owned groundwater wells. Tushaar Shah provides a fascinating economic, political, and cultural history of the development and use of technology that is also a history of a society in transition. His book provides powerful ideas and lessons for researchers, historians, and policy
