This paper reviews the literature regarding sediment storage within sinkholes and presents a case study, with the Pigeon Roost Creek and Hudgens Creek watersheds near the city of Cookeville, located on the Highland Rim in northern middle Tennessee. Sedimentation rates in these sinkholes were estimated based on age determination of cultural artifacts (buried trash and coal fragments) and by 14C dating. The analysis revealed that sinkholes undergo fill and flush cycles at different timescales caused by changes in upland sediment supply and morphologic changes at swallet openings. Sinkholes that lack swallet openings, or with swallets that have become blocked by debris, are effectively disconnected from master streams with regard to sediment. Sediment stored in sinkholes may be released downstream when swallet conditions change
