What are two significant problems that arise from floodplain development?

Floodplain development leads to significant alterations in the natural environment, particularly affecting how water flows and is absorbed in these areas. One of the primary issues is that development changes the natural floodplain's ability to absorb and manage floodwaters, often leading to increased flooding risks both on-site and in surrounding areas. This disruption can destroy existing infrastructure or lead to its increased vulnerability during flood events, causing widespread damage to property and critical services.

Additionally, human structures can interfere with natural water paths, leading to unforeseen consequences such as altered water flow patterns, which may exacerbate flooding downstream. This illustrates how development not only impacts the immediate area but also significantly influences the overall hydrology of a region. Hence, the awareness of these problems is crucial for effective floodplain management and maintaining community safety and environmental balance.
