Flash floods are such a pain, especially to merchants and street vendors who stand to lose the most in this emergency situation. One of the more aesthetic preventive actions is the 360° Water Barrier. Essentially this is a road barrier that is seen dotting the city roads in the low-lying areas, and has expandable metal shutters that can be used to prevent or divert the flow of the water. With a couple more refinements, this could become a do-able concept. What do you think?
