Description: STATISTICS IN PRACTICE A practical exploration of alternative approaches to analyzing water-related environmental issues Written by an experienced environmentalist and recognized expert in the field, this text is designed to help water resource managers and scientists to formulate, implement, and interpret more effective methods of water quality management. After presenting the basic foundation for using statistical methods in water resource management, including the use of appropriate hypothesis test procedures and some rapid calculation procedures, the author offers a range of practical problems and solutions on environmental topics that often arise, but are not generally covered. These include: * Formulating water quality standards * Determining compliance with standards * MPNs and microbiology * Water-related, human health risk modeling * Trends, impacts, concordance, and detection limits In order to promote awareness of alternative approaches to analyzing data, both frequentist and Bayesian, statistical methods are contrasted in terms of their applicability to various environmental issues. Each chapter ends with a number of set problems for which full answers are provided. The book also encourages discussion between technical staff and management before embarking on statistical studies.
Description: In order to provide water security in the 21st century there is universal agreement that a continuation of current policies and extrapolation of trends is not an option. Also clear is that from both water supply and development perspectives, the world's arid and semi-arid regions are those currently and potentially experiencing the highest water stresses. One third of the world's land surface is classified as arid or semi-arid and about half the countries are directly affected in some way by problems of aridity. The hydrology of arid and semi-arid areas is also known to be substantially different from that in more humid regions. It is therefore essential that investigation methods appropriate to the former are developed and applied; i.e. strategies for arid and semi-arid region water resources development must recognize the principal characteristics in 'in situ' hydrological processes.

Description: This book comprises the proceedings of the International Conference on Water Resources of Arid and Semi-Arid regions of Africa. Africa's resources are threatened by an increasing population. It is important that the water resources in arid and semi-arid regions are developed in a sustainable manner. After an introduction about the difficulties in obtaining data, the main subject of groundwater recharge is discussed in various aspects: natural and artificial; socio-economic aspects of water demand management; geophysical, GIS and remote sensing techniques for groundwater exploration; climate change and its impact on water resources; vulnerability and risk assessment, and water management.
