The Hamrin Dam is characterized by being one of the largest and most stable expansion dams in Europe allowing for greater efficiency and compactness. The weakness of the main dam is the inactive outlet which relies on seepage. The dam's layers are composed of layers divided into product zones with different properties and are affected by additions based on the style and precision of their engineering social characteristics and conditions all of which affect the investment expansion. In this study three geometric models of the Hamrin Dam were analyzed using the full Geo-Slope program (SEEP/W) simulating three methods or forms: (1) original design (2) side partition and (3) wall partition. Since the original design was extensive it recorded a minimum light leakage rate of 2.2117 × 10⁻⁴ (ft³/s³/ft³) with a protection permeability of 0.099 and a fire velocity of 1.0020 × 10⁻⁶ (ft³/s³) at a definition level of 270. It was found that extending the cut-off wall was not cost-effective as there was no significant loss of leakage flow velocity or useful water gradient with the wall remaining intact having little effect on properties. This proves that the Hamrin Dam is highly efficient since it introduced a monitor on its original design which led to a successful outcome and full cost.
