Available in PDF, EPUB and Kindle. Book excerpt: Groundwater hydrology is the SCIence that considers the occurrence, distribution, and movement of water below the surface of the ground. Groundwater is water located beneath the ground surface in soil pore spaces and in the fractures of geologic formations. A formation of rock/soil is called an aquifer when it can yield a useable quantity of water. The depth at which soil pore spaces become saturated with water is called the water table. Objective of this study is to relate the relationship of the groundwater flow movement due to pumping condition and to prove Darcy's Law equation is relevant to be applied in the study of groundwater flow. Based on title of the study, this project was carried out by using hydrology apparatus inside the laboratory with single pumping mode condition and seven different values of pumping flow rate (Cn.The measurement of piezometer head showed the illustration of water table drawdown in the ground when using the same size of sand which is 0.5 mm in the catchments area, and the same value of hydraulic conductivity (K) was equal to 3.0 x 10-3 m/day. Data from laboratory was compared with the value that simulated from Darcy's Law equation. The comparison of the data is not much different. The value of differences between Darcy's Law and experiment value were not exceeded than 10 percent. It's proved that the equation formulated by Henry Philibert Gaspart (1806¬1871) is valid to be applied in hydrology study. The result of this study highlighted the effects of pumping activity on water table level; higher rate of the pumping could cause the higher drawdown of water table especially at the well point. -Author.

There are many method of obtaining hydraulic information from aquifers, but perhaps the most common and best is the pumping test or aquifer test. Without an estimate of the hydraulic properties of an aquifer, calculation of groundwater movement cannot be performed with any level of confidence. In other word, pumping test is the best method to obtain the hydraulic information. Objective of this study is to relate the relationship of the groundwater flow due to the pumping activities using 2 different conditions and determine the value of hydraulic conductivity (k) due to uniform size of sand. In more advance, the objective of this study to prove the Darcy's Law equation is relevant to applied in the study of groundwater flow. This study was carried out by using hydrology apparatus in the laboratory UMP with single and double mode pumping condition. The measurement of piezometer head showed the illustration of water table drawdown in the ground when using same size of sand which is 0.75 mm in the catchment area. There are 12 cases condition with 3 different initial groundwater levels which are 65 mm, 100 mm and 135 mm. This study was carried out in confined and unconfined aquifer Even though the flow rate, Q was set different value, hydraulic conductivity, k show that it still in the range of 0.01-10 mm. Data from the laboratory was compared with the value that stimulated from Darcy's Law equation. The value of differences were not much different and its can be proved that the equation is valid to apply in the hydrology field especially in groundwater pumping study. The result of this study highlighted the effect of pumping activities on water table: higher rate of pumping could cause the higher drawdown of water table especially at the well point. Then, if the pumping rate is too slow, a small cone of depression will result and the drawdown in observation well may be detected. Conversely, if pumping rate are too high, then the test will not run very long because the pumping level will reach the pump.

Book excerpt: With the growing concern about groundwater resources both with respect to quantity and quality, the need for groundwater modelling tools is increasing. Although there are a number of excellent introductions to the concepts of groundwater flow and pollution transport, the student or practising engineer wishing to develop a model and do practical work on the computer finds that there is still a gap between the understanding of concepts and the ability to handle the actual computations. A great deal of groundwater modelling software for personal computers and microcomputers has appeared recently, but taking these models from the shelf and applying them without a background on their capabilities often leads to disappointment and frustration. This book provides the reader with all necessary details to start modelling on his own. It gives a comprehensive introduction to the major techniques currently used in the modelling of groundwater flow and pollutant transport in groundwater. Both self-contained and comprehensive, it presents a wide variety of methods currently applied in the management, protection, and remediation of groundwater resources, which allows the reader to take the step from understanding the concepts to the ability to handle actual computations. All major techniques are illustrated by a total of 19 sample programs in BASIC which can be modified by the reader to suit his own need. The programs can be run directly on an Apple II+ or compatible personal computer, and with slight modifications, most can be transferred to other microcomputers with BASIC capability and at least 48K of central memory. The necessary modifications for running the programs on an IBM-PC are indicated in the appendix.Students and professionals in the fields of hydrogeology and civil and environmental engineering will find this to be an extremely useful book. Knowledge of the basic concepts of hydrogeology is assumed and, starting from that basis, the book will enable them to understand mathematical groundwater models and write computer programs of their own.

Book excerpt: Advanced Simulation and Modelling for Urban Groundwater Management - UGROW Groundwater plays a vital role in the urban water cycle but is frequently ignored. The assessment and evaluation of urban water systems rarely consider the contribution of groundwater to the urban water budget, and available decision-support tools for integrated urban water management often fail to include aquifer storage and the strong two-way interaction that commonly occurs between groundwater and surface water and other urban water system components. Advanced Simulation and Modelling for Urban Groundwater Management - UGROW presents the result of a project of UNESCO's International Hydrological Programme on the topic. The book presents UGROW - a complete and fully integrated Modelling package - for simulating urban water systems. As a decision-support tool for urban water management, it focuses on urban groundwater, but all other key urban water system elements are fully represented and seamlessly linked. The theory behind UGROW is thoroughly described in the book, with three case studies illustrating how UGROW can be applied in practice. A CD-ROM containing a fully functional version of UGROW is included in the book.

Available in PDF, EPUB and Kindle. Book excerpt: This valuable new book, with 2 programs on diskettes, will help practitioners in solving groundwater flow and contamination problems by integrating simulation techniques. The reader is expected to have knowledge of hydrogeology, and have access to books on groundwater hydrogeology. Two microcomputer programs, in compiled FORTRAN 77 with source codes for simulating quasi-three-dimensional groundwater flow and contaminant migration, are presented in this book. The numerical and analytical techniques incorporated in these programs are described in detail. Data entry has been simplified so that the user can run the programs without worrying about FORTRAN input file structures and editors. The basic requirements are a monitor, dot-matrix printer, and an IBM-PC or compatible computer running DOS Version 2.1 or compatible. Programs require a full 640K RAM (minus that used by DOS) for their operation.
