A HIERARCHICAL APPROACH FOR GROUNDWATER MODELING

Abstract

In Egypt, there has been a major effort to improve the water supply especially for groundwater. Applications of numerical models to field scale problems require large grids which are not adequate with actual size of well diameter. Several methods have been used to simulate head at the well scale but these methods have limitations, especially for large scale problems. The paper presents a hierarchical approach for groundwater modeling which enables converting a large, complex problem into a network of smaller models that can be easily solved. The study aimed to provide an accurate representation of head in large scale problems.
