Book Description
The Science of Land Subsidence explains the current science underpinning natural and human-made land subsidence events, and provides students and interested readers with sufficient background on the basics of geology, natural science, chemical, and environmental engineering. Moreover, it presents a wide-ranging discussion presented in the author’s comprehensible conversational style describing the impact of land subsidence events on health, sustenance, and society in general, and provides various case studies covering catastrophic land subsidence events. This book is directed at undergraduate and graduate students, professionals, scientists, and the general reading public who would like to gain a broad multidisciplinary view of one of the greatest challenges of our generation. • Describes the impact of land subsidence events on health, sustenance, and society in general. • Provides various case studies covering catastrophic land subsidence events.

Book Description
In this book are reported nine works related to land subsidence monitoring using remote sensing techniques. Land subsidence is a common phenomenon in many regions of the world, where it causes degradation of local ecosystems and disruption of economic activities. Its effects are more evident in densely populated areas in particular in low-lying territories such as river deltas and coastal areas where the combination of land subsidence and sea level rise increases the flooding risk. For this reason, the monitoring of ground deformations is a crucial step to obtain important information for the development of risk mitigation strategies. In the presented papers, the characteristics of land subsidence occurring in different study areas are described, and recent developments in the used methodologies for the monitoring of the ground displacements are discussed and validated also by means of ground-based data. Moreover, advantages and disadvantages of the adopted techniques are highlighted. The outcomes of these research works can provide national and local authorities with useful information for the implementation of integrated monitoring systems in the areas most affected by land subsidence.

Book Description
Cities built on unconsolidated sediments consisting of clays, silt, peat, and sand, are particularly susceptible to subsidence. Such regions are common in delta areas, where rivers empty into the oceans, along flood plains adjacent to rivers, and in coastal marsh lands. Building cities in such areas aggravates the problem for several reasons: 1. Construction of buildings and streets adds weight to the region causing additional soil deformations. 2. Often the regions have to be drained in order to be occupied. This results in lowering of the water table and leads to hydro-compaction. 3. Often the groundwater is used as a source of water for both human consumption and industrial use. 4. Levees and dams are often built to prevent or control flooding. Earth fissures caused by ground failure in areas of uneven or differential compaction have damaged buildings, roads and highways, railroads, flood-control structures and sewer lines. As emphasized by Barends , "in order to develop a legal framework to claims and litigation, it is essential that direct and indirect causes of land subsidence effects can be quantified with sufficient accuracy from a technical and scientific point of view." Most existing methods and software applications treat the subsidence problem by analyzing one of the causes. This is due to the fact that the causes appear at different spatial scales. For example, over-pumping creates large scale subsidence, while building loading creates local subsidence/consolidation only. Then, maximum permissible land subsidence (or consolidation) is a constraint in different management problems such as: groundwater management, planning of town and/or laws on building construction. It is, therefore, necessary to quantify the contribution of each cause to soil subsidence of the ground surface in cities urban area. In this text book, we present an engineering approach based on the Biot system of equations to predict the soil settlement due to subsidence, resulting from different causes. Also we present a case study of The Bangkok Metropolitan Area (BMA).

Book Description
This book examines the process of injecting treated wastewater into wells to replenish aquifers, and thereby slow the process of land subsidence, and help to mitigate coastal flooding. It explains how up to fifty percent of sea-level rise may be due to land subsidence, and up to fifty percent of land subsidence may be due to aquifer compaction. The concepts covered discuss replenishing aquifers with clean water to reduce nutrient discharges into out-falled waterways; providing a sustainable supply of groundwater; reducing the rate of land subsidence; and protecting the groundwater from saltwater intrusion. Practical case studies from Virginia and California will be included.
