Pemetaan Profil Sungai dan Endapan Sedimentasi Secara Teresterial di Sungai Bengkel, Bengkalis

The workshop river in one of the rivers in Bengkalis that leads directly to the sea, which is located on Jl. Jendral Sudirman. This river is a port for marine police, i took this title to provide convenience in monitoring the sedimentation height and sedimentation rate per 2 month, so a survey oriented to a geographic information system in needed, this study describes s geogrsphic information
system that producer activity locations, sedimentation heights, sedimantation rates, location coordinates and location maps in the from of contour maps At the research stage and data processing using the result of field surveys
whic are processed with civil 3D software, Microsoft exel, and integrated with GPS coordinate data, to get the accuaracy of the maps made precisely, the method used in this research is the terresial method, which means conucting a direct field survey. The result obtained during the 2 month survey are contour maps and sedimentation rates in the form of maps and volume counts, with a volume of 35.81 m³, form these result it can be concluded that the annual sedimentation can be predicted and can be used as a guide for monitoring sedimantation conditions in the workshop river, Bengkalis.
