Information from space–based sensing and imaging systems has been widely available in digital format from the middle 1970s. The systems for processing and viewing digital image data became more readily available in the 1980s. This information has been used for such diverse hydrologic purposes as analysis of distribution of hydrogeologic units; estimation of areal extent, depth, and sediment content of water in lakes and streams; distribution, health, and abundance of riparian and phreatophytic vegetation; establishment of environmental baselines; estimation of ocean temperatures; and investigations for occurrence of water on other planets. Much of the preliminary analysis is now automated using commercially available processing software. Processed images can be used to describe hydrologic features and may require calibration through ground truthing. Time series images from earliest availability to present provide information for numerical analysis of changes in hydrologic features.

Understanding flow in the vadose zone is critical for a proper understanding, and ability to analyze, ground water – surface water interactions, ground water recharge, response of unconfined aquifers to pumping, subsurface contamination and the remediation of contaminated sites. This session will focus on recent advances related to these important topics.
