Scaled depth of burial formula

WebProven technology. Our Depth of Burial software (DOB) continuously calculates the burial depth of your cables based on the measured ampacity, distributed temperature of the cable and types of soil. This results in an overview of overall burial depth, adjustable alarms and historic analysis, all of which can be integrated in your SCADA system or ... WebJul 1, 2024 · Most scholars choose the main parameters: charge (W), depth (d), crater radius (R), the density of soil (ρ), and bulk modulus (K). By dimensional analysis, the density of soil (ρ) has been removed from the portfolio, which means that the cratering scale does not depend on the material inertia.
