JOESCO flood wall teaches you how to call for help when you are trapped by water:

  When a person or a group of people is trapped by a flood in a relatively solid highland or masonry residential building, they can be relieved as long as they keep in an orderly way and wait for rescue or for the flood to recede.If the flood is trapped in the low-lying stream bank, adobe or timber houses, and the situation is critical (as described in the debris flow), the communication tools can be used to report the flood situation and trapped conditions to the local government and flood control departments for rescue;If there is no communication condition, it can make fireworks, wave colorful clothes or call for help together, and send out urgent help signal to the outside world for help as soon as possible.At the same time, we should look for larger volume of flotsam and take the initiative to rescue measures.
