Water Wall

Water is everywhere; in nature it can vary from a vicious, fast flowing waterfall to calm, lazy rivers. As a species that relies on water to live, of course we would innovate water. For example, there are machines that pressurize water to cleanly cut materials. In Sydney, Australia, they have used water as a form of protection. There is a water wall installed at the entrance of the bridge to prevent enormous cars from hitting the structure. I feel that this water wall, though it is very aesthetically pleasing, is not sustainable.

The specifics of the water wall are unknown to me. However, its possible properties and mechanics should be evaluated. For instance, Sydney is nearby ocean water. Would it imply that the water wall consists of salt water? If so, the salt could damage the infrastructure unless there is a mechanism that captures and reuses the water. On the other hand, if the water was fresh, drinkable water, then it would be a waste of water.

If the water wall existed in Minnesota, perhaps it would be more sustainable by using rainwater or melted snow. Yet, weather would be a challenge for the wall. The wind would knock the water out of its water capturing system or the cold weather would potentially freeze the water, making the tunnel entrance blocked.

In other words, the water wall would only be feasible and sustainable in specific environments.

  1. I am not 100% certain of the specifics but the water wall was primarily developed to be used in emergencies. I have heard in the past of this type of technology being used for pedestrian crossing areas and child crossing areas where it helps warn drivers to slow down and pay attention. One of the main instances that they cite is that it could help prevent motorists from accidentally entering a tunnel that could contain a hypothetical fire or road hazard. The Aussie government adapted these to warn truck drivers that were about to enter a tunnel that was too small like you mentioned. I agree there are a lot of drawbacks sustainability-wise, but the overall costs of not having to fix a tunnel from damage far outweighs the costs and usage of water. As far as looks go, I agree with you that this is aesthetically pleasing.
