Abstract
Embankments are structures that are used especially for water storage, energy production, and irrigation. The type of embankment depends on the purpose of storm water to be used such as detention and retention, ground water recharge, surface water harvesting, flood control etc. and the available soil material for construction. Broadly, two type of embankment can be assumed, namely, homogenous embankment and zoned embankment. In this study, seepage through an earthen embankment’s body is investigated using analytical and computer approach. Seepage is investigated since seepage both in the embankment’s body and under the foundation adversely affects embankment’s stability. This study specifically investigated seepage in embankment’s body. Mahananda embankment is a homogeneous earthen embankment built on the impervious foundation. In the line of the purpose of this research, the seepage rate in an earthen embankment is estimated by Geo-Studio software (SEEP/W). Soil parameters such as soil type, Atterberg limits, moisture content (w) and unit weight of soil (γ), hydraulic conductivity (k) have been determined using field and lab experiments. Dimensional analysis was used with helping of the theoretical results to develop an empirical equation in order to determine the quantity of seepage through homogenous earthen embankment without filter resting on impervious base. Also, Verify the SEEP/W results with an artificial model and compare with analytical methods.
