Case History S.R. 237 in Perry County, Indiana

Four generalized types of landslides will be discussed during this presentation: high bluff peeloff, groundwater blowout, deep-seated, and shallow colluvial. The presentation will include case histories that describe approaches for repairing slopes of these types and combinations of these types of landslides, for improving the stability of slopes that could be affected by landslides, and for reducing the hazard from debris flows to highways and properties below landslides

Assessing Slope Instabilities

INDOT’s Geotechnical Services Section has recently implemented a slide ArcGIS Collector app to provide a systematic approach to collecting and managing unsafe or failed slopes/embankments needed for decision making. A brief background in Indiana landslide geology will be given, then we will review the process of how to inventory slopes through the Collector app and identify potentially hazardous slopes. The session will end with a discussion of current engineering practices INDOT is using to correct landslides
