Flood management tech seeks to reduce risks of fatalities, property damage

The most common type of severe weather emergency that affects American citizens and property owners is flash flooding, according to the National Flood Insurance Program. Flash floods, which can be caused by torrential downpours or the failure of man-made structures like dams or levees, causes rapid flooding of a low-lying area within six hours of the flood’s precipitating event. Half of all flash flooding fatalities are vehicle-related. With a coming El Niño that could dump a heavy amount of rainfall on southern California this winter, we wanted to revisit our Disaster Tech series to take a closer look at some flood management innovations being pursued to aid those in areas prone to flooding.

California won’t likely benefit from El Niño rains

Unlike Big Bear Lake, which will collect the runoff snowfall or rain, much of the rest of southern California is ill equipped to take advantage of El Niño rains. Those familiar with southern California will know that in beach towns there are signs on or near drains warning people not to dump things into the gutter because whatever goes into the drain will be released into the ocean. That, of course, also means that water that falls in beach communities in southern California will not be collected, or even useful. Due to perpetual poor government planning, even if El Niño does drop large amounts of rain water on southern California much of it will simply wind up in the ocean.

Strong El Niño weather pattern could douse some of California’s drought problem

We may not know the extent of rainfall California will receive for several months, but it has been made abundantly clear that El Niño is definitely coming. Even if we were to experience a wet and active El Niño this year, it wouldn’t likely be a healing salve for the entire state of California. El Niño’s effects are strongest in the southern parts of California. In the central and northern parts of the state, rainfall amounts aren’t really affected all that much. Furthermore, with much of California’s water reservoir system in the central and northern parts of the state, those basins will be unable to help capture excessive rainfall, which could mean real disaster for parts of Southern California.
