In African, hydrological regimes climate conditions may contribute to
Grace errors more than size of regime does
Measurement and leakage errors are a result of region’s aridity
Relying on scale factor in water storage, estimation is insufficient for
ground water storage
Sarron (2005)
South Africa
1970–2005
Continued destruction will result in decrease in water quality and less
reliable supplies (especially during dry season), increased severe flooding
and lower agricultural productivity
Schulze and Pike (2004) South Africa
As of 2002
The distribution of median values in the 41-year
129 record indicates that there is greater constancy of the Mkomazi
streamflows for the low flow season(e.g. 4.0 m 3
.s -1
)
There is a greater degree of inter-annual variation than for the high flow
season (e.g. 34.6, 49.3 and 32.2 m 3
.s -1
for January, February and March).
There is also a greater degree of inter-annual variation for high flow months
(CDs of 1.02, 1.21 and 1.31 for December, January, February) than for low
flow months (CDs of 0.65, 0.60 and 0.62 for May, June and July). Extreme
rainfall events in late September 1987 have influenced the inter-annual
variation of streamflows at the end of the low flow season, resulting in
