Qualitative Appraisal of the Hydrology of the Yemen Arab Republic from LANDSAT Images

摘要

LANDSAT images were analyzed in June 1976 to make a qualitative appraisal of surface-and groundwater resources in the Yemen Arab Republic (YAR) for use in water management planning in that country. Results of that appraisal are herein presented. Initial sections describe the YAR's environmental characteristics and previous hydrologic investigations, the LANDSAT imagery system, and the analytical methods used in the survey, the latter comprising a bibliographic search, image interpretation of geological, hydrological, and vegetative data, and reconnaissance field checking.
