Introduction 

Humans alter the surrounding environment and land to build our structures in both urban and rural settings. Although we often desire to be near features like rivers and shorelines, we take measures and we build a variety of structures to protect our properties and ourselves from the possibility of flooding and erosion. The following table lists some examples of each.
