Sediment Transport Capacity Calculator
Caller calibrated Meyer–Peter–Müller excess Shields bedload per width, no total suspended capacity, field sediment supply or universal coefficient. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
A Meyer-Peter-Müller-type expression estimates transport per unit width above a critical Shields value.
A Meyer-Peter-Müller-type expression estimates transport per unit width above a critical Shields value.1
Coefficients, grain properties and applicability are independently supplied model assumptions. Use this tool to calculate sediment Transport Capacity from the supplied measurements and assumptions.
When to use Sediment Transport Capacity Calculator
Use this tool to calculate sediment Transport Capacity from the supplied measurements and assumptions. Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
How to use Sediment Transport Capacity Calculator and understand its results
- Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
- Enter callerShieldsStress, callerCriticalShieldsStress, callerMpmCoefficient, relativeSubmergedSedimentDensity, gravityMSecond2, grainDiameterM, using the field meanings and rules below, then run the tool.
- Read meyerPeterMullerBedloadM2Second. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerShieldsStress | Caller shields stress | number | Required |
| callerCriticalShieldsStress | Caller critical shields stress | number | Required |
| callerMpmCoefficient | Caller mpm coefficient | number | Required |
| relativeSubmergedSedimentDensity | Relative submerged sediment density | number | Required |
| gravityMSecond2 | Gravity m second2 | number | Required |
| grainDiameterM | Grain diameter m | number | Required |
Enter nonnegative Shields stress, critical Shields stress and coefficient, with positive relative submerged density, gravity and grain diameter. Clamp excess Shields stress at zero, raise it to 3/2 and multiply by coefficient×sqrt(relativeDensity×gravity×diameter³). Output is m²/s per unit width, not total sediment discharge.
transportPerWidthM²/s=C×max(0,theta−thetaCritical)^(3/2)×sqrt(s×g×d³) Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| meyerPeterMullerBedloadM2Second | Meyer Peter Muller Bedload M2 Second; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Coefficients, grain properties and applicability are independently supplied model assumptions. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
