Abstract

Sediment monitoring device using ultrasound was constructed. Location data of the monitoring position was identified by coupling with global positioning system. It was found that ultrasound at 40 kHz frequency was optimum for scanning the lake and bay sediments layer. Comparison between scanning results using ultrasound and chemical analysis revealed that there is a correlation between organic matter contents in the soil and scanning data.
