Geomorphic Response To Catastrophic Flooding In A Karst Mountain Stream System, Brighton-Blue Hole Watershed, Southwest Jamaica, Sarah M. Letarte
Geomorphic Response To Catastrophic Flooding In A Karst Mountain Stream System, Brighton-Blue Hole Watershed, Southwest Jamaica, Sarah M. Letarte
MSU Graduate Theses
The geomorphic effects of flooding are poorly understood in the karst, mountain watersheds along the southwest coast of Jamaica. This study describes the flow path and geomorphic response of an extreme flood event in the Brighton-Blue Hole watershed (BBHW) (6.8 km2) near Belmont, Westmoreland, Jamaica. A tropical depression classified as a >100-year rainfall event produced 32 inches of rain in a 24 hour period in Westmoreland on June 12, 1979. For this study, geomorphic indicators of flood disturbance in BBHW were assessed in 2017-18, finding that channel system responded to the flood with channel incision, debris flows, and …
Regional Stratigraphy And Distribution Of The Coastal Group, St. Elizabeth Parish, Southwestern Jamaica, Brett M. Kenning
Regional Stratigraphy And Distribution Of The Coastal Group, St. Elizabeth Parish, Southwestern Jamaica, Brett M. Kenning
MSU Graduate Theses
This contribution examines the characteristics and ages of sedimentary units in the Coastal Group located along the southwestern Jamaica coast between Great Pedro Bluff and Fort Charles Bay in southwestern St. Elizabeth Parish. The coastline is characterized by laterally discontinuous low cliff exposures, separated by modern beach deposits and tectonically raised shore platforms composed of the White Limestone Group (mid-Eocene to mid-Miocene) and coral rudstone to floatstone and calcareous sandstone of the Coastal Group (late Pleistocene). Electron-Spin Resonance spectroscopy conducted on corals collected from a coral rudstone to floatstone facies yielded an estimated age of 120 ka. The coral facies …
Beach Form, Change, And Mangrove Interactions Along Galleon Fish Sanctuary, South Coast Jamaica, Kayla Marie Geier
Beach Form, Change, And Mangrove Interactions Along Galleon Fish Sanctuary, South Coast Jamaica, Kayla Marie Geier
MSU Graduate Theses
Shoreline erosion is a problem around the world that is getting worse as sea level rises and populations expand into coastal areas. It is important to identify areas at the greatest risk for shoreline erosion so environmental planners will have the knowledge and time to mitigate potential resource losses. The Galleon Fish Sanctuary in St. Elizabeth Parish is a 6 km stretch of shoreline along the south coast of Jamaica composed of mangrove forests, sand beaches, and coral reefs. This study assesses shoreline form and composition in the sanctuary in order to provide new information about the relationships between beach …
Recent Shoreline Erosion Rates Along Black River Bay, Jamaica: Erosion And Recovery After Hurricane Ivan In 2004, Karen Louise Zelzer
Recent Shoreline Erosion Rates Along Black River Bay, Jamaica: Erosion And Recovery After Hurricane Ivan In 2004, Karen Louise Zelzer
MSU Graduate Theses
Rising sea level is threatening coastal areas, particularly those in the Caribbean which rely heavily on tourism and marine resources to support local economies. The purpose of this study is to analyze shoreline position along the south coast of Jamaica to determine the locations and rates of coastal change. IKONOS satellite imagery sets for 2003, 2007 and 2012 were used to monitor land use and shoreline changes along Black River Bay, including Galleon Beach Fish Sanctuary, in St. Elizabeth, Jamaica. In particular, the effect of Hurricane Ivan in 2004 on shoreline changes was evaluated. Erosion rates were significantly higher during …
