Model results showed that the probability of encounter (contact between an egg or larva and one or more units of the intake array) ranged from 1.71% under the conditions of a high river flow and low withdrawal rate to 99.99% under the conditions of a low river flow and high withdrawal rate.
An analysis of slug test data at two different river flow stages (one test was performed at a low river stage with clean water and the other at a high river stage with muddy water) suggested that sedimentation from fine-grained particles, i.e., physical clogging processes, likely led to a reduction in streambed hydraulic properties.
High chl-a in low river discharge conditions can be driven by sediment resuspension events in shallow waters (depth less than 10 m) where dissolved inorganic nitrogen and dissolved inorganic phosphorus mineralised from particulate nitrogen and phosphorus in benthic sediment are injected back into the water column (Chongprasith 1992;Walker 1981 Muslim and Jones 2003 Ullman and Sandstrom 1987).

In 2011, late rains, dry spells and low river levels led to a 25% decrease in crop production in Mali, and a 50-60% rise in food prices above the five-year average.
