What are the pros and cons of soft engineering?
Soft engineering
Soft engineering
Advantages less expensive more enviromentally firendly increases the value of the area- can attract tourists
Disadvantages not sutible where areas are very developed requires lots of ongoing maintenance which is expensive not always as effective as hard engineering
How effective is soft engineering?
Soft engineering does not involve building artificial structures but takes a more sustainable and natural approach to managing the coast. Compared to hard engineering, soft engineering approaches are less expensive, are more long-term, attractive and sustainable as they work with natural processes.
Is Rip Rap soft engineering?
Vegetated riprap is a soft shoreline engineering technique that is an alternative to conventional riprap for erosion protection. Conventional riprap is a form of rock armor, rubble, or concrete used to fortify shoreline structures against the forces of erosion.

Dams are the classic hard engineering solution to flooding problems. A dam is a giant wall built across a river’s channel to impede its flow. Water builds up behind the dam and forms a reservoir which can then be steadily drained at a controlled rate over time.
How do gabions work?
The baskets are filled with rock and stacked atop one another to form a gravity- type wall. Gabions depend mainly on the interlocking of the individual stones and rocks within the wire mesh for internal stability, and their mass or weight to resist hydraulic and earth forces.

Place a layer of filter fabric over on top of the exposed slope to prevent soil movement under the riprap. If filter fabric is used, it should be followed by a three inch thick layer of clean three fourths (3/4) inch crushed stone.
