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.
