Table 2.1 <strong>the</strong> surface area <strong>of</strong> each <strong>of</strong> <strong>the</strong> sub <strong>catchment</strong>s are written down. The names <strong>of</strong> <strong>the</strong><br />

sub <strong>catchment</strong>s are taken from Chapagain (2000) except from <strong>the</strong> change <strong>of</strong> name <strong>of</strong> Lake<br />

Malawi into Lake Nyasa.<br />
