Landslides cause much damage to property throughout metropolitan Cincinnati, Ohio.
Most landslides occur in unconsolidated deposits, including colluvium, till, glacial lake clays, and man-made fill derived from colluvium and glacial deposits. Increased knowledge of the distribution and causes of landslides, gained through many investigations across several decades, has contributed to the formation and adoption of landslide mitigation programs by the City of Cincinnati and Hamilton County, Ohio. For example, both city and county have adopted an excavation and fill ordinance to help reduce landslide damage in areas of new construction. The series covers investigations in all phases of hydrology, including hydrogeology, availability of water, quality of water, and use of water.
