5 high-tech small-scale flood control systems

Ang Metro Manila at mga rehiyon sa kasaysayan ay ngayon'y nagbabago mula sa malaking paglalakbay ng tubig at bigang pagkapandig. At kahit ako'y naglalakbay sa aking mga sandbag na itinulong upang mapanatili ang tubig sa loob ng aking bahay, hindi ko napakahangad kung mayroong mga sistema sa pagkontrol ng tubig sa skala ng kabataan na maaaring gamitin natin sa tahanan. Ito ang mga bagay na nakatagpo sa akin hanggang ngayon.

Isabel sa balangay

Ang mga dam ng gumamit na tubig sa gilid, ang pinakamahalagang sistema ng pagkontrol ng amihan sa mundo. Ito ay mga pamamaraan ng gumamit ng tubig sa gilid na adunay gilid nga gumamit sa lágo, nga gitukod sa ruta sa daghang tubig aron mailagpas ang pag-adto o makamit ang pagpangandalan sa tubig. Ito adunay lainlaing mga size ug gitukod gamit ang tubig, gilid o kini nga duha.

Artificial sandbags

Normal sandbags are sacks usually filled with, well, sand. With artificial sandbags, a special super absorbent chemical powder is used instead of ordinary sand. One example of this product is the Quick Dam.

When not in use (dry) it just weighs than less than a pound. It can absorb up to 4 gallons of water and weigh up to a maximum of 30 lbs.

Flood barriers

Flood barriers are custom-made systems that are installed on doors, windows and garages. It's basically an easy to install watertight wall that you can put up to prevent floods from coming in to your house. One example is the Floodark system. Take a look at the video below (skip to 1:50):

HESCO Concertainer units

A HESCO Concertainer unit is a multi-cellular wall system manufactured from welded zinc-aluminium coated steel wire mesh and joined with vertical, helical coil joints. The units are lined with a heavy-duty non-woven polypropylene geotextile.

In essence, these are high-tech mesh baskets that are filled with dirt or sand. Normally, these are used by soldiers as walls to deter incoming fire but can be used to block off water.

Aqua Levee

The Aqua Levee is a flood control system that consists of triangular cross-section tube-like structures that are filled with water and stacked to form a temporary levee (or dyke). These levees will be pumped with water and can be installed in dry or flowing conditions.

And there you have it. Most of these flood control systems are only available in the U.S. but we're hoping that some can make it here or a company based in the Philippines can manufacture some since we can certainly make use of it in times like these.
