Channel Levee Height Estimate
Compare observed levee height to an ideal yield/gravitational slab scale; not a channel-capacity or overflow forecast, and rheometry-based yield inference is a separate tool.
Description
Yield strength can support an ideal material layer on a slope.
Yield strength can support an ideal material layer on a slope. The associated depth scale can be compared with measured levee height.
Compare observed levee height to an ideal yield/gravitational slab scale; not a channel-capacity or overflow forecast, and rheometry-based yield inference is a separate tool.
When to use Channel Levee Height Estimate
Use this tool to compare observed levee height to an ideal yield/gravitational slab scale; not a channel-capacity or overflow forecast, and rheometry-based yield inference is a separate tool.
Gather the relevant observations and fitted model parameters. Use the stated units and time basis; keep paired observations aligned.
How to use Channel Levee Height Estimate and understand its results
- Gather the relevant observations and fitted model parameters. Use the stated units and time basis; keep paired observations aligned.
- Enter depositYieldStrengthPa, bulkDensityKgPerM3, gravityMPerSecondSquared, slopeAngleDegrees, observedLeveeHeightM using the field table and calculation rules, then run the tool.
- Read modelYieldLimitedHeightM, observedMinusModelHeightM. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| depositYieldStrengthPa | Deposit yield strength Pa | number | Required |
| bulkDensityKgPerM3 | Bulk density kg per m3 | number | Required |
| gravityMPerSecondSquared | Gravity m per second squared | number | Required |
| slopeAngleDegrees | Slope angle degrees | number | Required |
| observedLeveeHeightM | Observed levee height m | number | Required |
Use positive density and gravity, nonnegative yield strength and observed height, and slope strictly between 0° and 90°. Return the height scale and observed-minus-modeled difference.1
yield-limited height = yield stress/(density × gravity × sin(slope)) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| modelYieldLimitedHeightM | Model yield limited height m | number |
| observedMinusModelHeightM | Observed minus model height m | number |

}Limitations and assumptions
This is a slab scale, not a channel-capacity or overflow forecast.
Numbers and computed results must be finite; overflow produces an error. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Bingham Yield Strength Lava: Infer Bingham yield intercept and plastic viscosity from measured yielded shear pairs; negative intercept or nonpositive slope is rejected instead of asserting a physical yield law. For a complementary task, use Newtonian Yield Stress Regime Checker: Screen caller negligible-yield approximation and ideal Bingham shear at applied stress; unyielded states return zero modeled shear, not a flow-safety determination.
