Numerical simulation model of water-logging phenomenon at Al Jahza camp Al-Zubair town, Southern Iraq

Abstract

The current study is focused on the groundwater modeling with three scenarios as future plans to find a suitable solution for the problem at Al-Jahza Camp south east of Al-Zubair town, south of Iraq. The objective of the study is find out a numerical model for simulating the behavior of the groundwater flow using (MODFLOW) software. The model was calibrated in the steady and transient states for four randomly distributed monitored wells in the study area with 21 stress periods. Suitable match was obtained from the comparison between the levels of the observed and calculated heads. The model was simulated to control the water-logging. The water level of the simulated head remains extremely constant in condition of constructing the underground barrier. By Supposing of digging wells and increasing the water pumping with an average of 432 and 216 m/day, the head level at exceeding extraction with constructed subsurface barrier decreased more than the head level in case of increasing the water pumping with no subsurface barrier to reach 35-40 cm and 45-50 cm respectively, and to enhance the benefit to control and decrease the water from waterlogged area in the future.
