It has become imperative on the part of water scientists and planners to adopt techniques for quantifying the available groundwater resources for sustainable development and management keeping in mind the scarcity of available water resources versus its demand in the near future. The apparent heterogeneities and complexities present in the hard rock aquifers makes it a challenging research to tackle groundwater problems. The intricacy increases manifold for the management of groundwater when the hard rock aquifers are situated in arid or semi-arid regions. The demand/supply gap has led to the over abstraction of the groundwater and water level depletion in many areas beyond economic exploitation.
The Indo-French Center for Groundwater Research (IFCGR) at Hyderabad, India has taken this challenge and using a suitable pilot site with all the requisites for studying hard rock aquifers present, has surveyed and experimented extensively a typical granitic aquifer present in a semi-arid and monsoon climate agricultural area. The present book contains the results and findings of the advanced research carried out in the pilot area with a thorough investigation of the structure and functioning of the aquifer in such a formation. The various chapters arranged in the book start from a very general scenario of the water resources management in the country, an extremely technical contribution on the hard rock aquifer system, its characterization, theoretical portion of its properties and behaviour that has been necessary to enter into the environment. A brief description of various experiences of studying the hard rock aquifers globally has been included to provide a much wider experience. The rest of the book has very systematically included the geophysical, geological and remote sensing applications to conceptualize such an aquifer system. The basics of the hydraulic tests, conducting various types of examinations for parameter estimation in such aquifers including their up-scaling with modern interpretation techniques are embedded. Another chapter has been included describing the water budgeting and balance in granitic aquifers using the specific methods for their estimation. A major parts covers the advanced techniques of geostatistics and aquifer modelling right from the basics and then demonstrated by suitable case studies. Finally a few examples have been included on the hard rock aquifers from extreme North and also from the South of India with case studies to complete the matter for its readers. The reader of the book will find comprehensive knowledge with suitable examples to investigate a hard rock aquifer for characterization of its flow properties, estimating water balance and finally aquifer modelling for groundwater management including the theory of regionalized variables. Colour diagrams wherever necessary have been included for clear understanding.
