What?

On the contrary, the efforts made in recent months have saved the city from being overrun. The levies that broke were pre-existing and the only flooded area is the central depression which amount to roughly about 10% of Beledweyne.
A portion of the populace evacuated because they anticipated that the new flood prevention mechanisms would not hold but they are returning as of today.
The flood prevention project was an incredible success. Reer Beledweyne have managed to tremendously mitigate the recurrent wreckage that has been dealt to the city in recent years. With a bit more work, it looks like the city will be safe from floods in a few years. Hopefully, what Beledweyne achieved will be an example for all flood prone areas in the riverine south
Sxb, this isn't about 'my dusty village is less dustier than yours.' The future of Beledweyne and its people is at stake. The truth is, Hirshabelle administration miserably failed the people it represents. Already, there are 3-4 floods just this year, not mentioning the years before. The gu' season is on the horizon, and one can only hope for better outcome.
You've claimed only a 'portion of the populace evacuated', but the following videos of a long line of trucks, cars, gaari dameers, bajaajs, etc contradict your claim:
It's beyond the expertise & resources of Xaaji Dhagaxoow and the few engineers with him to do something effective against the floods. Instead of industrial/military grade cement, they've used plain cement that wouldn't hold much. Some of those interviewed in the video, like you, have praised the efforts of the Xaaji and engineers, but unlike you, those interviewed told the truth that the efforts haven't borne tangible results.
Already, parts of the city submerged for months are unlivable & abandoned. With the likelihood (hopefully not) of more floods, the locals are gonna be forced to give up. Hence my previous question; What can be done to help the locals?
