An Assessment of Remote Sensing Applications in Hydrologic Engineering.
Abstract
The current status of techniques, limitations, and applications of remote sensing to hydrologic problems of rainfall estimation, snow cover monitoring, water quality monitoring, and hydrologic modeling and runoff computation was reviewed. Tabulated data for 29 remote sensors indicated for each sensor the resolution range, spectral interval, spacecraft or aircraft that sensor has or could be flown on, and the major hydrologic parameters that could be measured or inferred. The thirteen hydrologic parameters listed were: surface temperature, cloud cover, atmospheric liquid water content, snow cover, water equivalent of snowpack, vegetation, land use, soil moisture, short wave radiation in radiation budget, long wave radiation in radiation budget, water bodies configuration, soil types, and basin area. Each sensor was capable of measuring from one to none of these parameters. The capability of remote sensing to gather regional scale synoptic information offers the potential of greatly enhancing watershed modeling. (Author)
