The monthly discharge and sediment load distribution curves of the entire recorded periods (hydrological year 1995-2017 at Kratie, hydrological year 1993-2016 at Chroy Changvar) (Figure 7) show similar monthly patterns in high and low sediment load (i.e., equal or exceeding 5% and 95%). However, monthly highest discharge differed significantly. The flow distribution at Kratie and Chroy Changvar confirmed the downstream reduction in gaged flow at Chroy Changvar occurring at higher flows. The peaks of discharge and sediment loads were 133 km3/month and 40 Mt/month at Kratie, 95 km3/month and 33 Mt/month at Chroy Changvar.
