Statistical Processor for Analyzing Simulations Made Using the Modular Finite-Difference Ground-Water Flow Model

摘要

Many hydrologic studies of ground-water systems are conducted using a digital computer model as an aid to understanding the flow system. One of the most commonly used ground-water modeling programs is the Modular Three-Dimensional Finite-Difference Ground-water Flow Model (Modular Model) by McDonald and Harbaugh. The report presents a computer program to summarize the data input to and output from the Modular Model. The program is named the Modular Model Statistical Processor and is designed to be run following the Modular Model. The Modular Model Statistical Processor provides ground-water modelers with the capabilities to easily read data input to and output from the Modular Model, calculate descriptive statistics, generate histograms, perform logical tests using relational operators, calculate data arrays using arithmetic operators, and calculate flow vectors for use in a graphical-display program.
