    Groundwater is an important water supply for households, industry, and agriculture.One-third of the world's drinking water comes from groundwater. The main objectives of this study are of this study is to investigate the effects of groundwater flow directions on the design of drainage plans. The study involved field investigations to measure modeling input parameters and numerical modeling using the Groundwater Modeling System (GMS) code. It examined the effects of a subsurface drainage system, including net drainage recharge rate, equivalent drain depth, and drain spacing. This research was applied to the real-world case of the Mashtul pilot area (MPA) in EgyptThe study was conducted using field investigation to measure the modeling input parameters and numerical model using the Ground Water Mgroundwater modeling (GMS) code by numerical model by investigating the effects of the subsurface drainage system, including the net drainage recharge rate, the equivalent drain depth, and the drain spacing s. The study was applied for to two cases, : the first is a hypothetical case, and the second isthe real case of Mashtul Pilot Area (MPA), Egypt. The results showed that the lateral arrangement had a a high performance by orienting at 90 o , 135 o, and 45 o angles in which t. The groundwater levels reached 5.63 m, 5.33 m, and 5.51 m above mean sea level for the three orientation cases, respectively, at the baseline case. Also, the results showed that the decreasing the drainage rates and increasing the equivalent drain depth have a greater effect on increasing the groundwater levels while increasing the drain spacing led to an increase in the groundwater levels in the study. This study approach is useful for the future arrangement of laterals subsurface drainage systemsin underground drainage
