Understanding Jetty
Jetty is a perpendicular beach building located on both sides of the river estuary that is useful for reducing transplantation by beach sediment and for flood prevention.
Some of the benefits of jetty include:
- Streamline inter-country / domestic trade through waters
- Strengthen the defense and security of a country based on political, economic and technical considerations, such as military ports.
Explanations Concerning Jetty Functions include:
- To reduce transplanting of sedimentation by sedimentary beach sediments in the estuary can disrupt vessel traffic, Jetty withstand turning of river mouth and concentrate flow there is a predetermined flow to erode the sediment, so that at the beginning of rainy season where when big debit (flood) has not happened , the river mouth has opened.
- For flood prevention, one can use one of the following buildings, ie long jetty, medium jetty or short jetty. Jetty long when the end is outside the breaking wave. This type is effective for blocking the entry of sediment into the estuary, but construction cost is very expensive, so if its function is only for flood prevention jetty usage is not economical. Unless the area that must be protected against flooding is very important. Medium jetty, where the tip is between the low tide level and the location of the breaking waves, can withstand some of the sediment shipments along the coast. The grooves at the end of the jetty still allow the occurrence of sand deposits. On a short jetty, the foot of the building's end is on the low tide level.
