Deltaic sedimentation in a modern rift lake

Five of the largest deltas of Lake Malawi in Africa were surveyed to compare and contrast bathymetry, bedform distribution, and sedimentary facies using high-resolution seismic reflection profiling, side-scan sonar, and sediment coring. Striking variability in delta morphology and depositional facies was found, depending primarily on tectonic setting but also influenced strongly by lake processes and the significant past variability in lake level resulting from climatic change. -from Authors
