| Zusammenfassung |
| An assessment to describe and quantify the extent of
changes in the channel and lagoon system of the Sudd was carried out using
Landsat satellite images of 1973, 1979, 1997 and 2002. Using supervised
classification and visual interpretation after referencing the images, the
water bodies for a representative area between Bor and Shambe (a stretch of
150 km) were delineated. The resulting files were compared to establish and
quantify changes in-between the years and as well compared to Lake Victoria
outflow data to assess a likely correlation which was found for the largely
water level dependent lagoon system. Changes in the channel system were
interpreted to happen in a certain pattern but the extent of changes could
not be correlated to the outflow data as they are influenced by other, here
not considered factors like wind drift and channel blockages by vegetation. |
