Beach Erosion Hazard Vulnerability Assessment of Bamburi Beach in Mombasa, Kenya
M. A. Mwakumanya
Abstract—Beach accretion and/or erosion are evident on the
Kenyan shoreline leading to loss of the aesthetic value of the
beaches and destruction of shoreline properties. It is more
prevalent on the Bamburi shoreline, which is about 4km long,
and has been attributed to anthropogenic and natural processes
that interfere with longshore drift depriving the beaches of
sediments. Inadequate hazard assessments of the morphological
processes on the beaches have made shoreline management
interventions impracticable. Hazard vulnerability assessment
obtained from the mean beach sediment volume was used to
understand the differential and site specific spatial vulnerability
of beaches to erosion on the shoreline. Accretion was revealed
along Baharini challets - Private home, Whitesands-Sai rock,
Papweza-Bamburi villas and Giriama beach-Jambo Ree
shorelines, while erosion was experienced at Private home –
Severine beach, Severine beach – Whitesands beach, Sai rock -
Papweza, Bamburi villas – Kenyatta beach and Kenyatta beach
- Giriama beach shorelines. Site specific vulnerability
differences and morphological dynamics are evident along the
shoreline. Spatial adaptive management strategies, including set
back regulations and impact assessments, revegetation of the
shoreline and simple engineered protection structures should be
adopted and enforced to ensure stability of the shoreline and the
beach system.
