Über dieses Buch

This book provides insights on and tools for the characterization of island aquifers, as illustrated by the example of the coral islands of Lakshadweep in India. After an initial overview of the different coral islands, subsequent chapters explain key geophysical, hydrogeological and hydrochemical methods for the assessment and characterization of coral island aquifers. The book’s closing chapters highlight selected case studies and describe actual implementations of the methods discussed. In addition to presenting the details of data collection on each island – a valuable resource for any future study on these islands – in graphical form, the book proposes suitable measures for ensuring the sustainability of groundwater resources on the islands. Accordingly, it offers a unique and essential source of information for all hydrogeologists whose work involves island aquifers.

Frontmatter

Chapter 1. Introduction

Abstract

Water is essential for the survival of living being and their development. A very small part of total water available on the earth is potable. The water resource of India is described. The significance of the potable water resources becomes very significant in case of small coral island with high population density. The potable water on small coral island is found in the form of thin floating groundwater lens. The formation of small coral island is presented.

Chapter 2. Groundwater as Freshwater Resource

Abstract

In order to evaluate the water resources on the small coral island, it is essential to understand the conditions under which the aquifer is formed.

Chapter 3. Delineation of Fresh Groundwater Zone on Island

Abstract

The estimation of thickness of groundwater lens is vital for the management of groundwater.

Chapter 4. Characterization of Island Aquifer

Abstract

The characterization of island aquifer is an important step towards the assessment and management of freshwater resources on the island. The two essential parameters are aquifer transmissivity and storage coefficient. Pumping test is a common approach to estimate aquifer parameters.

Chapter 5. Chemical and Biological Characterization of Island Aquifer

Abstract

The chief source of freshwater resource on the coral island is precipitation that percolates and gets the subsurface aquifer saturated to form floating groundwater lens. The precipitation may also be stored on the ground surface either as runoff accumulation or roof top collection in tanks and ponds.

Chapter 6. Management of Groundwater

Abstract

The management of groundwater resources on the small island is vital as it is limited in nature. Further, there are several stresses on it, some are natural and some are manmade. The assessment of total quantity of freshwater is essential step towards fresh groundwater management.

Chapter 7. Case Studies

Abstract

Various investigations and studies had been carried out on four islands of Lakshadweep to assess groundwater resources and suggest various approaches to sustain groundwater on these islands. These islands are Kavaratti, Andrott, Kalpeni and Minicoy islands. The population density on these islands is high and so is the demand for potable water.
