How does geology affect coastal erosion

WebFlooding is a natural phenomenon that occurs when water overflows its banks and spreads onto the surrounding land. Rivers are one of the most susceptible areas to flooding due to their location, topography, and geology. Flooding can cause severe damage to both human life and property, as well as ecological systems. WebThe geology of an area influences the rate of river erosion. For example, rivers flowing over hard rock have a slower erosion rate as the bedrock is more resistant. However, areas with soft rock are more likely to experience higher rates of erosion.
