The objective of this study was to determine the factors responsible for the high frequency of landslide occurrence in the Kope Formation and the overlying colluvial soil present in the Cincinnati area and to prepare a landslide inventory map. . The area around Cincinnati is one of the most landslide susceptible regions in the United States. Several million dollars are spent yearly by the government and private entities to repair landslide damage. Landslides within the Cincinnati area generally occur in colluvium derived from the Kope Formation. The Kope Formation consists of approximately 80% shale inter-bedded with 20% limestone. The colluvium that is formed from the weathering of the shale consists of a low plasticity clay. There are two main types of slope failures that occur in the Cincinnati area: rotational slides and translational slides. An inventory map was created using LiDAR data of the landslides that occurred in the colluvium derived from the Kope Formation. From the landslide inventory map, ten landslides were chosen for detailed study and undisturbed samples were collected from each site for laboratory testing. Of the ten landslide sites chosen, seven were rotational and three were translational in nature. One sample, representative of the slide material was collected from each rotational landslide. Two samples were collected from each translational landslide, one from the overlying colluvial soil and one from the underlying bedrock. Tests were conducted to determine natural water content, Atterberg limits, shear strength parameters, dry density, grain size distribution, and slake durability. For the translational landslides, strength parameters were determined by shearing the sample along the contact between the bedrock and the overlying colluvium. Multiple factors were found to contribute to landslide susceptibility of the Kope Formation and the overlying colluvium. These factors include: low shear strength of the colluvial soil; development of pore water pressure within the slope; human activities such as the addition of weight to the top of the slopes or the removal of material from the base of the slope; low to very low durability of the bedrock that allows rapid disintegration of the bedrock and accumulation of colluvial soil; undercutting of the slope toe by stream water; and the steepness of slopes.
