Description :
The impact of wastewater flow on the channel bed morphology was evaluated in 4 ephemeral streams in Israel and the Palestinian Territories : Nahal Og, Nahal Kidron, Nahal Qeult and Nahal Hebron. Channel changes before, during and after the halting of wastewater flow were monitored. This change is likely to have substantial implication, as the main feature of arid fluvial systems is their ephemeral nature, high magnitude infrequent flow events, and sporadic sediment transport. Within a few months, nutrient-rich wastewater flow leads to rapid development of vegetation along channel and bars.
