COMPARISON OF SEEP/W SIMULATION WITH OBSERVED SEEPAGE IN EARTHEN DAM

The present research work is designed to compare the seepage of earthen dam using finite element based software GEOSTUDIO subpr oduct SEEP/W with field observed seepage through earthen dam. GEOSTUDIO software is capable to perform analysis such as, stress - strain, seepage, slope stability, dynamic analysis. SEEP/W ,a subproduct of GEOSTUDIO is a finite element software which can s imulate the movement and pore - water pressure distribution within porous materials like soil and rock. In present work the seepage of water through earthen portion of Ujjani dam ,an earthfill cum masonary dam in Maharashtra is computed and phreatic line is simulated for single chainage. The observed actual field results of seepage are compared with results obtained by GEOSTUDIO software sub product SEEP/W.
