Canal and Canal Levee Stability under Pseudostatic Loading, Vetiver Grass, and Rapid Drawdown Conditions

This dataset contains GeoStudio (Slope/W 2025) numerical models developed for the integrated stability assessment of earthen canals and canal levees under hydraulic, geotechnical, and seismic loading conditions. The study focuses on the Khush Tepa Canal, Afghanistan, and evaluates slope performance under steady-state seepage, rapid drawdown, and pseudostatic earthquake loading conditions, as well as the reinforcing effect of vetiver grass as a bioengineering solution. The analysis is performed using the Morgenstern–Price limit equilibrium method and considers multiple scenarios to simulate realistic field conditions, including groundwater effects, transient hydraulic loading, and seismic inertial forces derived from site-specific seismic parameters. Three main GeoStudio models are included in this dataset: Steady-state seepage slope stability model Rapid drawdown slope stability model Pseudostatic seismic slope stability model with and without vetiver grass reinforcement The study evaluates a critical section (IT3) of the Khush Tepa Canal, which is characterized by sandy and silty soils, shallow groundwater conditions, and high susceptibility to instability. The results demonstrate significant reductions in factor of safety under seismic and rapid drawdown conditions, while showing notable improvements in stability due to vetiver grass reinforcement. This dataset supports research on: Canal and levee slope stability Seismic performance of earthen embankments Rapid drawdown effects Bioengineering slope stabilization using vetiver grass Limit equilibrium modeling using GeoStudio Slope/W The dataset can be used for academic research, engineering design comparison, and further numerical modeling studies in geotechnical and hydraulic engineering.
