Set general goals

Habitat
assessment

Set specific objectives and set design criteria
Obtain approval from project stakeholders

Prepare sediment studies plan

Ye s

Determine values for design discharge
and bed material gradation

No

Can overall goals be
met by alternate
design?

Conduct a stability assessment

No

Does project involve channel reconstruction?

Ye s

No

Will channel boundary be mobile at design discharge?

�reshold approaches
to obtain channel width,
depth, and slope

Active bed approaches
to obtain channel width,
depth, and slope

Determine planform geometry and lay out channel right-of-way

Add geometric detail (physical variability) and habitat features

Check stability of restored channel under
projected postconstruction conditions

No

Is stability satisfactory?

Implementation/construction

Monitoring

Best management practices (BMPs) are generally understood as practices that are intended
to reduce the pollutant content of nonpoint source discharges, such as pathogens or indica-
tor species (e.g., coliform bacteria), pesticides, organic materials, sediments, and nutrients.
