Making a nautical chart for safe navigation is a bathymetric survey's primary goal. Multifrequency MBES, developed during the last few decades, has dramatically improved the efficiency, accuracy, and spatial resolution of coastal and ocean mapping. The goal of multifrequency MBES is to increase the sub surface ’s detection resolution. In order to obtain an accurate picture of the seabed, the user can lessen the impact of this subsidence by running surveys in five different modes at once. With the help of multifrequency MBES, this study will analyze bathymetry in shallow coastal waters. According to this study, each frequency’s density equals one-fifth of the raw data. The digital bathymetric model (DBM) has identical frequencies. According to the produced DBM, the study site’s depth value ranges from -2.5 m to -23.5 m LWS. Between 200 kHz and other depths, a bathymetric variation of little more than 50 cm. Between 200 kHz and other frequencies to -10 cm, the bathymetry range of 0 cm predominates. Dredging volume inter frequencies falls between 0.042 m3/m2 and 0.068 m3/m2. This amount is negligible compared to the overall dredging volume with a thickness of more than 1 m inside 1 hectare.
