Regional Groundwater Flow Modeling of Aldamer Area, River Nile State – Sudan
Journal Title: International Journal of Applied Science and Mathematics - Year 2018, Vol 5, Issue 5
Abstract
The three-dimensional groundwater flow model was performed to evaluate the groundwater potentiality and assess the effect of groundwater withdrawal to the regional water level and flow direction in the Eldamer area central Sudan. Data used include periodic water level measurements, meteorological data, digital elevation data and well logs from scientific test wells and domestic water wells drilled in the study area. Transient visual MODFLOW model code was calibrated. Numerical simulation indicated that, a sharp drop of hydraulic head can be observed at the center and east of the model area, generated cone of depressions and a continuous decline of head with respect to the time as a result of heavy groundwater abstraction. The central part of the area, represent relatively high permeability zone and the model confirmed it to be the most productive region in the area and can be used for storing additional groundwater. Observation wells elaborate the reasonable match between the observed and calculated heads through the entire simulation period.
