HYDROLOGY
In 1969, the Keurbooms River maintained a mean annual runoff of approximately 127 x 106 m3 (Ref. 4).  In 1981 the mean annual discharge into the Keurbooms River exceeded 72,9 x 106 m3 (Ref. 2).  In 1975, the flow of the Keurbooms River is below 0,30 m/s, even at springtide, due to the high friction coefficient of the river (Ref. 5).  The mean annual Runoff (MAR) of the Keurbooms River , as reported in 1999, was 207 x 106 m3 (Ref. 6). 
The mean annual run-off of the Keurbooms catchment is 215 million m3        (Ref. 11).
