Sediment Yield Analysis of Gangapur Dam using SWAT and GIS
Abstract: Sediment yield in reservoir is one of the major factors that plays role in functioning of any dam storage. Sediment yield not only affects the reservoir capacity but also can affect the generation of hydropower and safety of dam as well as aquatic life. GIS (Geographic information system) based SWAT (soil and water assessment tool) are used in this study to calculate the sediment yielded in reservoir of Gangapur Dam …

Influence of Aeration and Curing on Shear Strength of Asphalt Stabilized Soil
Abstract: Asphalt stabilization technique is usually used to control and improve poor subgrade soil condition. The subgrade soil is the foundation for the roadway structure, its responsibility is to provide the required stability for the overlaying pavement and to limit the deformation due to traffic load repetitions by furnishing homogeneous stress distribution. In this work, the unconsolidated undrained Triaxial test was implemented for comparatively assessing the impact of asphalt stabilization on …

Near-Surface Seismic Refraction Tomography; a case study for geotechnical application
Abstract: Usually, among geophysical techniques, seismic refraction methods are used to investigate near surface geology for engineering purposes. In these study physical parameters, longitudinal seismic wave velocities were used to characterize the shallow subsurface layers for geotechnical application. The physical response of subsurface materials varies as the structure, porosity, fluid saturation, composition and tie-up vary. These variations primarily viewed in the first arrival time of seismic waves. With the necessary steps, …

Probability of Liquefaction induced Ground Failure under the Earthquake Scenario in Kathmandu Valley
Abstract: Kathmandu valley is highly susceptible to liquefaction hazard due to the presence of liquefiable soil up to considerable depth, the presence of shallow ground water table and occurrence of earthquakes at regular intervals. Past studies have also shown the occurrence of liquefaction with examples of observed ejection of sand boil and formation of cracks throughout the valley during 1934 Nepal-Bihar earthquake. Events similar to these were also observed during recent …

Development of an Intelligent and Statistical Model for Prediction of Rock Mass Deformation Modulus
Abstract: The rock mass deformation modulus (Em) takes into account the plastic and the elastic deformation of the rock mass. It has been widely used for designing structures such as dams, tunnels, caverns, and mines, etc. Since the tests available for ascertaining Em are expensive and time consuming, several equations were suggested in the past. However, it has been found that the existing models are limited to specific type of rock …
