Abstract
The temporal trend analysis found that the open water portion of the Cheleleka wetland to fall from 12Â km2 in 1972 to 5Â km2 in 1986, 3Â km2 in 1995 and 1Â km2 in 2000; very little area remained in 2007 and 2016. The current functional performance is estimated to be high for water quality improvement (2.3 out of 3 points â 77%); medium for ground water recharge (2 out of 3 points â 67%) and peak flood attenuation (1.2 out of 3 points â 40%). To purify a BOD5 of 463Â mg/l (actual) to a BOD5 of 50Â mg/l (design target), a total required treatment area of â 20,689Â m2 is required according to the volumetric process design model, and 64,276Â m2 by the areal-based model.
