A CONTINUOUS MONITORING SYSTEM FOR POROSITY CHANGE IN A SANDY BEACH DUE TO RUNUP WAVES

Abstract

 Sampling methods involve destruction of sediment and they cannot be implemented in high frequency. Therefore, in this study, we have developed and proposed a time continuous monitoring method of sediment porosity change under wave action. The monitoring system consists of usage of inexpensive electrical resistivity sensors and calibration technique that is based on porosity-electrical resistivity logarithmic relationship. The compaction effect of suction dynamics on swash zone has been examined through a experiments by using the method proposed in this study.
