Abstract
High elevations of groundwater at Mosul city is a very big problem and may cause massdestructions to the environment, health and Building foundations due to the closing of groundwater nearground surface to a depth of water in many places (less than 1 m). From filed investigations for 43 largediameters shallow wells, the water elevations were measured 14 times through 7 months. Utilizing rasterbased GIS operations with automated parameter estimation (PEST) the conceptual model was build andconverted to numerical model. After model calibration the hydraulic conductivity values have been found.The elevations, path lines and flow vectors maps were drawn from model results. Three sectors forgroundwater elevations in the city have been defined and introduced to the water management agency forprompt decisions. The distributed finite-difference flow code (MODFLOW) selected in this study hasapproved to be a useful tool for creating a groundwater flow model for the study area. The results of themodel can be used for the sewerage net design in Mosul city also for the planning of the agriculture andindustrial projects.
