Groundwater Modeling Utilities is a handy reference guide designed to help groundwater industry professionals learn to use a variety of microcomputer software applications for groundwater modeling and numerical modeling in flow and contaminant migration studies. The book provides the following: (1) handy operation and logic reference supplements to selected groundwater model, pre-processor, post-processor, geostatistics, graphics, CAD, and word processing software supporting documentation; (2) selected model operation practice exercises with extensive step by step input/option prompt and response documentation; and (3) six convenient model database manipulation utility programs stored on two 5-1/4" diskettes included with this book. The disks can be used with all IBM and IBM-compatible computers. The utility programs allow you to convert values from one system of units to another; interpolate between control data points on a curve or surface; calculate heads and partial penetration effects in production wells; create, edit, and convert grid, triplet, listed, and unformatted model data files; and view tabular and category displays of model data files. Groundwater Modeling Utilities covers some of the most popular and thoroughly tested public domain finite-difference numerical microcomputer model software; commercial model software; public domain geostatistics software; and commercial graphics, CAD, and word processing software. Using actual groundwater modeling-specific examples, learn to work with software such as MODFLOW, MOD PATH, MOC, INTERTRANS, INTERSAT, GEOPACK, GRAPHER, SURFER, CADD 5.0, and WordPerfect 5.1. Groundwater Modeling Utilities is a book no groundwater industry professional can afford to be without.

Written by renowned experts in the field, this book assesses the status of groundwater models and defines models and modeling needs in the 21st century. It reviews the state of the art in model development and application in regional groundwater management, unsaturated flow/multiphase flow and transport, island modeling, biological and virus transport, and fracture flow. Both deterministic and stochastic aspects of unsaturated flow and transport are covered. The book also introduces a unique assessment of models as analysis and management tools for groundwater resources. Topics covered include model vs. data uncertainty, accuracy of the dispersion/convection equation, protocols for model testing and validation, post-audit studies, and applying models to karst aquifers.

Cutting-edge techniques for groundwater modeling using GIS technology Groundwater Modeling Using Geographical Information Systems covers fundamental information on flow and mass transport modeling and demonstrates how GIS technology makes these models and analyses more accurate than ever before. GIS technology allows for swift organization, quantification, and interpretation of large quantities of geohydrological data with computer accuracy and minimal risk of human error. This book's companion Web site provides the Princeton Transport Code, as well as the plug-in extensions required to interface this code with the Argus ONE numerical environment software enclosed with this book. Plug-in extensions for MODFLOW and MT3D computer codes can be found at the Argus ONE Web site (www.argusint.com). The process for using the Geographic Modeling Approach (GMA) to model groundwater flow and transport is demonstrated step by step with a field example from Tucson, Arizona. The GMA is composed of the Argus ONE Geographic Information Modeling system and the Princeton Transport Code groundwater flow and transport model, interfaced through the plug-in extension available on Argus ONE. Enhanced with more than 150 illustrations and screen captures, Groundwater Modeling Using Geographical Information Systems is a fundamental book for civil engineers, hydrologists, environmental engineers, geologists, and students in these fields, as well as software engineers working on GIS applications and environmental attorneys and regulators. When used in combination with the free modeling software, this book provides an excellent student text.

Quantitative Solutions in Hydrogeology and Groundwater Modeling addresses and solves a variety of questions and problems from hydrogeological practice. It includes major aspects of quantitative groundwater evaluation, from basic laboratory determination of hydrogeological parameters to complex analytical calculations and modeling for engineering purposes. Groundwater modeling is a strong trend in hydrogeology. Recent years have seen the rapid development of sophisticated and powerful groundwater models, along with a decrease in the use of the more mathematically demanding analytical quantitative solutions. Quantitative Solutions in Hydrogeology and Groundwater Modeling avoids this conflict by explaining both modeling and mathematical solutions in detail.

This report documents (1) a number of stand alone utilities to assist with input to MODFLOW and (2) code modifications internal to MODFLOW and MODFLOWP. These were developed to improve ease of use of MODFLOW and MODFLOWP for modeling groundwater flow in three dimensional heterogeneous systems. Several utilities to assist with input to MODFLOW are specifically designed for use with the Groundwater Modeling System (GMS) pre and post-processor package. New features for MODFLOW include routines for: (1) assignment of material blocks and material types to these blocks within a given three dimensional grid mesh; (2) generation of the Block Centered Flow (BCF) file for heterogeneous aquifers with material properties assigned to blocks, and with internal calculation of leakance and thickness factored parameters (T, S); (3) distribution of pumping rate for individual model layers for a well that draws from or injects into multiple layers; (4) calculation of weighted drawdown for an observation well screened over multiple layers; and (5) customizing the drawdown output file to contain data for a specified number of observation wells, rather than every node in the domain. For MODFLOWP, the program has been modified to: (1) simplify input by making the PAR file free format; (2) allow the user to easily change the number and combination of parameters for estimation in a given run by modifying one line rather than regenerating the PAR file; (3) automatically calculate ROFFs, COFFs, and TOFFs for observation wells; (4) notify the user during program execution when lower or upper parameter ranges are exceeded; and (5) provide monitoring of run time.
