Sentence examples for estimated bedrock from inspiring English sources

Conversely, dry ERT only estimated bedrock depth (RMSE = 0.2 m) in the case of a high contrast of the resistivity between the soil and bedrock.

Figure 3 Map of geology for study area with estimated bedrock permeability.

For example, two of the sites (Wolfville, NS and McCarthy, AK) had the same estimated bedrock age (300 my) but significantly different mean 87Sr/86SrF ratios (1-tailed t-test; t5 = −3.82, P = 0.006).

This study shows that GPR and MASW can provide complementary results in estimating bedrock depth.

SASW correctly estimated the bedrock depth (RMSE = 0.3 0.7 m) in all situations except in the case of shallow soils.

To estimate the bedrock depth conclusively, MASW testing was performed at the same site.

Combining two geophysical methods to estimate the bedrock depth has greatly contributed to the credibility of the results, as can been seen for the first site.

To estimate the bedrock depth, both GPR and MASW experiments were carried out at the first site of the study area.

Although Bristow and Jol (2003) have observed that 100 MHz antenna provides the best trade-off between depth of penetration and resolution of the image, after a sensitivity analysis at the site, lower-frequency antennas of 80 and 35 MHz have been used here considering that the main objective of the study is to estimate the bedrock depth.

Values of estimated age of bedrock were log-transformed to meet normality requirements.

Recharge to the bedrock is estimated at ∼27% of the annual precipitation over the period 2005 2010, recognizing the uncertainty in this estimate due to data limitations, parameter uncertainty and calibration errors.
