ABSTRACT

It has been established that the expected climate change in the next 100 years will be due to anthropogenic activities. The expected climate change will impact all sectors of the human endeavour. Therefore, all countries who are signatory to the UN convention on climate change are required to carry out a vulnerability assessment. The computational methods that were utilized to generate information required to evaluate the impact of climate change on water resources in Swaziland are presented. 1080 climatological data points were generated in each catchment (27 tables in total) and 81 rainfall runoff simulations were carried out in the three catchments and this was possible through the use of a computer.
