STUDI FAKTOR PENYEBAB GERUSAN SALURAN ERODIBLE CHANNEL PADA DAERAH YANG DIPENGARUHI PASANG SURUT (Studi Kasus Jalan Sriwijaya Desa Teluk Pambang)

Abstract

In the village TelukPambang, type of drainage is still a lot of erodible channel can be found as channel type is considered economical and easy to manufacture. One drainage is directly influenced by tidal scour, so the potential to occur. General scour an erosive properties of water that occurs in a natural channel or river, instead of the effect of the existence of a building just as bridge abutments and others. At this time the cause of scours is limited to hypotheses that have not been explained scientifically by a study. The study was conducted by measuring several parameters such as flow velocity, channel dimensions, slope and the energy difference between the cliffs and the water channels. Some samples to represent the channel indicated scour occurs and some more samples for the channel is still in a stable condition is taken to be tested in the lab to get the parameters of the soil shear strength and shear angle in the soil samples.
