These invariably induced new trends and research directions at diverging scales. This paper is guided by three specific objectives: (1) to employ the Shuttle Radar Topography Mission (SRTM) in deriving the morphologic attributes of the Ikpa Watershed (11) to assess the association and effect of discharge on basin texture, infiltration rate, length of overland flow, and rainfall amount in the Ikpa Watershed, Akwa Ibom State. (111) To describe the relationship between discharge, rainfall amount, and morphologic attributes of the Ikpa Watershed. The watershed was stratified into six sub-basins and data (rainfall and discharge) systematically generated for three months each during the dry and rainy seasons; while the topographic attributes were generated indirectly using SRTM, backup with the four topographic maps. The analysis using multiple linear regression yielded a coefficient of 0.986. Also, the R square value of 0.859 implied that 85.9 percent of the proportion of Original Research Article
