Application of GIS and MODFLOW to Ground Water Hydrology- A Review

摘要

Groundwater is one of the most valuable natural resources, which supports human health, economic development and ecological diversity. Due to over exploitation, the ground water systems are affected and require management to maintain the conditions of ground water resources within acceptable limits. With the development of computers and advances in information technology, efficient techniques for water management has evolved. The main intent of the paper is to present a comprehensive review on application of GIS (Geographic Information System) followed by coupling with MODFLOW package for ground water management and development. Two major areas are discussed stating GIS applications in ground water hydrology. (i) GIS based subsurface flow and pollution modelling (ii) Selection of artificial recharge sites. Although the use of these techniques in groundwater studies has rapidly increased since last decade the sucess rate is very limited. Based on this review , it is concluded that integation of GIS and MODFLOW have great potential to revolutionize the monitoring and management of vital ground water resources in the future.
