Examine how human processes can have an impact on the operation of one of the following natural processes: - Mass movement processes - River processes - Leaving Cert Geography - Question 1 - 2006

Human activities have significant impacts on coastal processes, particularly through development, pollution, and climate change.

Human Impacts on Coastal Processes

1. Coastal Development: Urbanization along coastlines often leads to the construction of buildings, roads, and other infrastructure. This alteration can increase sedimentation and lead to enhanced erosion. By covering natural surfaces, stormwater runoff increases, which may cause pollutants to enter coastal waters.

2. Dredging and Land Reclamation: Dredging activities can alter natural water flow and tidal patterns, leading to changes in sediment deposition. Land reclamation efforts can disrupt local ecosystems and increase the vulnerability of coastlines to storm surges.

3. Pollution: Pollutants from industries and urban areas, such as heavy metals and oils, can significantly affect marine life. These substances can lead to bioaccumulation in marine organisms, disrupting food webs and harming biodiversity.

4. Climate Change: Human-induced climate change has led to rising sea levels and increased storm intensity. Coastal areas face greater risks of flooding and erosion, which can further impact human populations and infrastructure.

Conclusion

In summary, various human processes such as coastal development, dredging, pollution, and climate change profoundly affect coastal operations by modifying natural dynamics, leading to environmental degradation and increased vulnerability to natural disasters.
