The aims of this study is concerned of modeling the combined eco-hydrological components and its spatial distribution effect and evaluate its impact on the potential water flow of selected catchment in eastern Sudan. Spatial variability of landcover types and magnitudes was assessed using landsat7 and sentinel 2 images for years 1996, 2011 and 2018, topographic and soil type factors were used to assess the potentiality for runoff at sub catchment level using Curve Number approach. Rainfall records, Curve Number map and one gauge readings for stream discharge were used to simulate the hydrograph using 10 years return period and assess volumetric flow at sub-catchment level. Land cover changes showed reduction in natural vegetation through the studied periods. Curve Number was reflect the catchment high potentiality for generating runoff. The hydrograph analysis was generated and the runoff peak by means of volume and time during the storm event was generated. This study demonstrates this approach that can be used in agricultural promising areas for water management and planning purposes.
