Flooding in Houston, TX

Being of tropical origin, Houston is highly prone to experience hurricanes and floods. The subtropical water bodies, support the formation of hurricanes, which is kind of a storm but has many adverse effects. In simple words, we can describe hurricanes as a storm with a maximum speed of constant winds as 74mph; the main reason behind this is the warm ocean water and humidity of the city. Apart from this, the usual coastal flood due to high tides is very common in the region.

Flood are so impactful here that they can simply submerge an entire vehicle in less than an hour. The main factor behind such impactful flood is the heavy rain that gets accumulated on the ground, due to constant high-density rainfall. Houston even experiences “flash flooding”, this means, a sudden flood due to tremendously rising water along a low-lying area or a stream. Flash flooding is extremely abrupt, such that the residents of the affected area don’t even get time to evacuate. Hence, it causes immense loss to life and property. Even driving attempts are failed during a flash flood, as the vehicle may also get submerged or washed away due to the swift flood water. This causes a lot of motor accidents, and the probability of death of the victims is very high.

As mentioned earlier, Houston is a flood-prone area, so some preventive and flood preparedness measures are pre-required if you are a Houston habitant. For evacuating, during any disaster, you need help and support from other individuals. Instead of being selfish, a disaster requires citizens to be sympathetic and vigilant. Even the Government needs to step forth to help its citizens by setting up evacuation camps and emergency shelters with an adequate supply of food and other everyday necessities. Houston has seen many such Floods, so the Government is also well-aware of the requirements of the flood victims such as medical help, food supply, motivation talks, running tests for infections, protection from water-borne diseases, and so on.

The Government and the citizens of Houston have devised a disaster warning system from their past experiences; the citizens can send a “Reverse 911” call to warn the neighbourhood people about the occurrence of flood or any other disaster. They can even get to know about the recent weather broadcasting or disaster alerts by calling the City’s Office of Emergency Management at 713-884-4500 or by listening to the NOAA Weather Radio broadcasts made throughout the day.

Let’s have a look at the categories of flood encountered in Houston, TX:

1. Fluvial Floods

In common man’s term, fluvial floods are known as river floods. The most common cause is due to overflowing of an adjacent water body like rivers, streams, or lakes. The probability of fluvial floods increases after hurricanes or excessive rainfall. They can turn more adverse depending upon the amount of precipitation. If any of the dams get damaged, then the severity increases further.

They can be further divided into two sections, namely, flash floods and surface water floods. Both flash flood and surface water flood are abrupt as well as unpredictable. They can happen anywhere, even if a huge water body is not present nearby. Heavy rainfall in a short span of time leads to flash floods. They are more prone in hilly areas, where water slopes down into the valleys and gets accumulated. Surface water floods are caused mostly due to the failure or blockage in the drainage system.

3. Coastal Floods

As the name indicates, coastal floods are more prone in the coastal areas, where high winds blow during the high tides; this is also referred to as storm-serge. Due to a large number of hurricanes in the Gulf, Houston often experiences heavy rainfall, that ultimately leads to a flood. That’s why water damage in residential, commercial, and industrial properties is a pervasive issue faced by the people of Houston.

Some safety tips that you must follow during a flood:

What to do before a flood:

  • Always store important legal and educational documents on an elevated shelf.
  • You can install a water level sensor, that will give you a signal or ring an alarm if the amount of accumulated water exceeds a certain height.
  • Keep the contact details of the water restoration company handy with you.
  • Always arrange for cleaning and inspection of the drainage system to avoid blockages.
  • Have healthy vegetation nearby, to avoid soil erosion.

  • If the water level is rising continuously, evacuate or go to the upper floor.
  • Take your valuable document along with you.
  • Do not come in contact with floodwater, it might cause skin allergies or infections.
  • Do not stamp any naked wire lying on the ground; it might give you a shock.
  • If you’re inside a vehicle when the water level rises, abandon it and move to the elevated ground.
  • Don’t walk through the flood areas. Only 6 inches of water is sufficient to completely sweep you away.

What to do after a flood:

  • Do not enter the subjected property, until cleaning has been done.
  • During the cleaning process, wear a mask, gloves and other protective equipment to minimize exposure to possible hazardous materials.
  • Take extra efforts, like boil water before drinking to avoid getting water-borne diseases.
