Changes

More than 70% of the suspended load has settled in the system. This will inevitably lead to clogging and reduction in efficiency in the system, but also an improvement of the soil for agriculture purposes. Additionally, the managed aquifer recharge improves the quality of groundwater, as the EC of floodwater is much lower than that of the groundwater (0.3-0.4 versus 2.0-9.0 dS/m).
