Landslide Dams
Processes, Risk, and Mitigation
Landslide dams have proved to be both interesting natural phenomena and significant hazards in many areas of the world. A few of these blockages attain heights and volumes that rival or...
Granular Flow Theory Applied to Geologic Flows
Borehole Shear Test and Slope Stability
Three Iowa landslides analyzed on the basis of Borehole Shear Test (BST) data are reported. The soils included CL and ML loess and glacial till, and CH clay shale. Back-calculations from...
Landslide Investigations Using the Weight Penetrometer
The weight penetrometer is a light weight device and can be easily deployed on slopes not accessible to conventional exploratory tools such as drill rigs or cone penetrometers. The weight...
Landslide Investigation Utilizing Electric Cone Penetration Testing
A geotechnical investigation was conducted of landsliding at a hillside residential property to evaluate both the extent of the landslide and the stability of the fill materials as well...
The Mudslide Profile Method to Measure the Undrained Shear Strength of Muds
Mudslides have been reported to have a very distinctive profile. Using this distinctive profile, a method is presented to analyze the stability of the mudslide at limit equilibrium conditions....
Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...
Relative Landslide Susceptibility in Davis County, Utah?A Multivariate Approach
The complex distribution of soil properties makes prediction of slope stability extremely difficult in these mountain watersheds. The need to assess these watersheds for their susceptibility...
Generalized Methodology for Simulating Mudflows
In this paper, a one-dimensional dynamic flood-routing model, for non-Newtonian fluid properties, is described and applied to two different mudflow events: Holbrook Canyon, Utah, and Mount...
Responsibility/Liability Related to Mudflows/Debris Flows
The combined experiences of the authors during the past few decades indicate that many of the problems and losses related to damage from floods, landslides, mud/debris flows, and water-related...
Maintaining a Natural Gas Pipeline in Active Landslides
This paper deals with a pipeline section on both sides of Douglas Pass in west Colorado. Landslide activity in the area has been causing considerable problems and disruptions of the pipe...
Landslide Hazard Rating for the Oregon Coast Range
The landslide hazard rating system for shallow soils on steep terrain over hard sandstone has three components: ground water response to precipitation, soil shear strength (including root...
Density Transfer: The Santa Monicas Contribution
This paper addresses some aspects of designing and implementing density transfer programs, as illustrated by the Transfer of Development Credit (TDC) program which the California Coastal...
Probabilistic Seismic Sliding Deformations of Earth Dams and Slopes
Mechanics of Mudflows
A Bingham model is adopted to study the fluid mechanics of mudflows. Equations for predicting the transition from laminar to turbulent flow in an open channel are formulated and verified...
Prediction of Dam Overtopping Due to Mudflows
The eruption of Mount St. Helens on May 18, 1980 resulted in a small mudflow into Swift reservoir, which is located immediately south of the mountain. An engineering/geologic study was...
