A two dimensional analysis on the largest cross-section of earth dams gives accurate results, provided that the dam is located in a U-shape valley. The Vanyar Dam is constructed in a narrow valley. According to the geometry of the valley, there is not a plane strain condition throughout the long side of the dam. In this research, the results of three and two dimensional numerical analyses of the Vanyar dam are compared, in terms of settlement, pore water pressure and total vertical stress. These analyses are carried out by the finite difference method, using FLAC-3D and FLAC-2D software packages. The numerical results obtained for the settlements are verified by comparing them with measured settlement data. The settlements obtained by three and two dimensional analyses in the upper half of the height of the dam are in good agreement. Moreover, it is shown that for the lower half of the height of the dam, the settlements obtained by two dimensional analyses are generally greater than those obtained by three dimensional analyses. In the core axis at cross section C, the maximum settlement of 88.14 cm is recorded at the height of 48 m from the bedrock (
