The present study uses a satellite remote sensing approach for
assessing coastal sediment dynamics in the western side of the Zanzibar channel,
Tanzania. Four Landsat images (1986, 1998, 1999 and 2000) were used for the
study. Investigation of the four images revealed that the Ruvu delta north of the
river mouth has been growing rapidly, especially between 1986 and 1998, with an
annual northward linear growth rate of about 133m year{1 and an areal growth
rate of about 1 km2 every 3 years. The study identified a palaeo-shoreline feature
that is parallel to the present shoreline and located about 1.9km inland from the
present shoreline. An important sediment contributor to river Ruvu is derived
from the Uluguru Mountains, a tropical mountainous area located about 200km
from the coastline of the Tanzania mainland. The working hypothesis is that
either the observed growth of the delta occurred at a gradual rate between 1986
and 1998 or it was mainly an episodic event related to the extreme rainfall events
such as the 1997/98 El Nin˜o–Southern Oscillation (ENSO) event, which was
associated with extreme rainfall and widespread landslides. |
