Advanced Modeling / GIS
Computers and technical software have made advanced resource assessment and design tools available to water resources professionals. Aquifer analyses, assessment of water resources over large land areas, modeling of aquifer performance under existing conditions and under proposed stresses or under pollution conditions, all may be performed using advanced modeling, often within a timeframe of hours as opposed to a pre-computer timeframe of weeks or months.
Geographic Information Systems (GIS) are being used more often by both government and private sector entities to manage physical resources and related geographic data. GIS is also becoming an extremely useful tool for hydrologic investigations as more and more data sets become available in GIS-compatible format.
