hard and soft enginnering Flashcards
tell me what is hard enginnering?
use of physical structures and technologies to control or modify natural processes, typically in the context of managing water, preventing erosion, or mitigating the impacts of natural disasters.
what is a dams
Large structures built across rivers to regulate water flow, store water, and generate electricity.
tell me some examples of hard enginnering
Dams
Sea Walls
Levees
Gabions
what is a Sea Walls
Concrete or rock structures constructed along coastlines to protect against erosion and storm surges.
what is a Levees
Raised embankments built along riverbanks to prevent flooding by containing river water.
what is a Gabions
Wire mesh containers filled with rocks or other materials used to stabilize slopes and control erosion.
disadvantages and advantages of hard enginnering
ad/
.Hard structures provide robust and immediate control over natural processes.
.Some hard engineering projects, like dams, can provide additional benefits such as hydroelectric power.
dis
.hard engineering may have adverse effects on the environment, disrupting ecosystems and natural processes.
.Construction and maintenance costs of hard engineering projects can be high.
tell me some examples of soft enginnering
Beach Nourishment
Vegetative Cover
Managed Retreat
Floodplain Zoning
what is Beach Nourishment
Adding sand or sediment to a beach to restore its natural profile and enhance protection against erosion.
what is Vegetative Cover
Planting vegetation, such as grass and trees, to stabilize slopes and prevent soil erosion.
what is Managed Retreat
Allowing natural processes to occur by moving structures away from vulnerable areas, especially in the face of sea-level rise.
what is Floodplain Zoning
Designating specific land areas for controlled flooding to reduce the risk of damage to structures.
disadvantages and advantages of soft enginnering
ad
.Soft engineering solutions are often more environmentally friendly and compatible with natural processes.
.Soft methods can adapt to changing conditions and are more flexible over time.
.Soft engineering often involves community engagement and is more likely to be accepted by local populations.
dis
.Soft engineering solutions may take longer to implement and may not provide immediate protection in emergency situations.
.The effectiveness of some soft engineering methods may vary depending on local conditions and climate.
.Soft engineering may have less direct control over natural processes compared to hard engineering solutions.
