A qualitative appraisal of the hydrology of the Yemen Arab Republic from Landsat images

Landsat-1 and Landsat-2 images were analyzed in June 1976 to describe the flow regimens of streams and the regional distribution of vegetation in the Yemen Arab Republic (YAR). The findings provide a factual basis for planning a surface-water data collection program, and for preparing maps of plant distribution and agricultural land use. They lay the foundation for modernized water development, and for effecting a program of country-wide water management in the YAR.
