Download or read book Subsidence due to Fluid Withdrawal written by E.C. Donaldson and published by Elsevier. This book was released on 1995-03-29 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subsidence of geologic surface structures due to withdrawal of fluids from aquifers and petroleum reservoirs is a phenomenon experienced throughout the world as the demand for water and hydrocarbons increases with increasing population growth. This book addresses the definition and theories of subsidence, and the influences of unique conditions on subsidence; it includes discussions of specific field cases and a basic mathematical model of reservoir compaction and accompanying loss of porosity and permeability. The book is designed as a reference for readers giving immediate access to the geological events that establish conditions for compaction, the mathematical theories of compaction and subsidence, and practical considerations of field case histories in various regions of the world.

This book was released on 2013-01-05 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: Coastal aquifers serve as major sources for freshwater supply in many countries around the world, especially in arid and semi-arid zones. Many coastal areas are also heavily urbanized, a fact that makes the need for freshwater even more acute. Coastal aquifers are highly sensitive to disturbances. Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater utilization. As sea water intrusion progresses, existing pumping wells, especially those close to the coast, become saline and have to be abandoned. Also, the area above the intruding seawater wedge is lost as a source of natural replenishment to the aquifer. Despite the importance of this subject, so far there does not exist a book that integrates our present knowledge of seawater intrusion, its occurrences, physical mechanism, chemistry, exploration by geo physical and geochemical techniques, conceptual and mathematical modeling, analytical and numerical solution methods, engineering measures of combating seawater intrusion, management strategies, and experience learned from case studies. By presenting this fairly comprehensive volume on the state-of-the-art of knowledge and ex perience on saltwater intrusion, we hoped to transfer this body of knowledge to the geologists, hydrologists, hydraulic engineers, water resources planners, managers, and governmental policy makers, who are engaged in the sustainable development of coastal fresh ground water resources.

Book excerpt: This book addresses geohazards by establishing their unique hydrogeological conceptual site models. Geohazards occur in many forms and scales either naturally or induced by human's activities. Many geohazards such as earth fissure, ground collapse and subsidence, mine water inrush, and groundwater contamination are closely related to hydrogeological conditions and their dynamics. Water, either surface water or groundwater, acts as a resource and an enabling agent that elevates geohazard risks in areas that are inherently vulnerable. The book presents case studies to describe identification and investigation methods, monitoring and early-warning techniques, modeling approaches, and engineering measures to prevent, control, and mitigate these geohazards. It targets students, researchers, practitioners, and decision makers who are engaged in water resource management, project planning, and geohazard control and management.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Land subsidence due to groundwater pumping in the San Joaquin Valley of California is known to cause many negative side effects, including a loss of groundwater storage. The general theory behind surface deformation, which includes subsidence and rebound, due to changes in the groundwater system, is well established. Surface deformation occurs as a direct result of changes in water level in an aquifer system, and can be permanent or recoverable, depending on the stress history of the aquifer system. An advanced satellite method known as Interferometric Synthetic Aperture Radar (InSAR) can be used to measure surface deformation with ~cm accuracy, at a resolution of ~100 m and measurements every 10 to 40 days. In spite of our ability to measure surface deformation with this method, and the existing theory describing the relation of deformation to changes in water level, it remains challenging to relate this deformation to changes in the aquifer system because so much information is required to do so accurately. The goal of this thesis is to develop methods to improve our ability to monitor and model groundwater storage and quality by incorporating InSAR with geological, geophysical and water quality datasets. This includes developing methods that estimate how much observed deformation is permanent, methods that predict deformation given water level changes, and methods that relate deformation to arsenic contamination. By integrating multiple datasets with InSAR, we are able to extract more useful hydrogeological information that provides water managers with tools to map and model deformation due to changes in the groundwater system, as well as its impacts on groundwater storage and quality. Our key findings are that 1) in the San Joaquin Valley, 54-98% of the subsidence that occurred from 2007-2010 throughout our study area was permanent, 2) by combining InSAR data with airborne electromagnetic (AEM) data, we are able to model surface deformation over time and improve estimates of the subsurface hydrostratigraphy, as well as hydrologic, geomechanical and rock physics parameters, 3) our modeling indicates that the land has subsided by as much as 3 m since 1990 in one specific location within our study area, and 4) land subsidence resulting from overpumping is linked to arsenic contamination in the San Joaquin Valley aquifer system.
