Laboratory Observations and <strong>Algorithm</strong><br />
<strong>of</strong> Signal Interpretation<br />
• Normalized measured dielectric constant is linearly<br />
related to normalized sediment thickness<br />
• Normalized measured electric conductivity is linearly<br />
related to normalized sediment thickness<br />
• Salinity has minor effect on normalized measured<br />
dielectric constant.<br />
• Scour measurements based on dielectric constant is<br />
more stable.<br />
• Dielectric and electric mixing <strong>for</strong>mulas can be used to<br />
explain <strong>the</strong> observed linear relationship and to estimate<br />
scour depth from measured Ka and EC<br />
• Scour depth can also be estimated by indentifying <strong>the</strong><br />
reflection at water/sediment interface<br />
