The unit hydrograph was done after that, using the predicted water level in the piezometers and Thiessen polygons (Figure 8). The predicted unit hydrograph showed the routine fluctuation in the aquifer water table from September 2012 until August 2013. Also, Table 4 shows the aquifer domain predicted water table during this period. It can be seen that groundwater level depletes in dry months and rises in wet months such as March, April and May.
