How to Use the Antecedent Moisture Model

Introduction Antecedent moisture (AM) conditions, or the relative wetness or dryness of a system, can have a tremendous impact on rainfall-runoff dynamics. The magnitude of the runoff (flow) from rainfall can be affected by how wet the drainage area is from prior...

Best Practices for Flow Meter Data QA/QC

Best Practices for Flow Meter Data QA/QC

You have decided to embark on a flow metering project in your sewer system, perhaps to develop design peak flows or to perform an I&I analysis. Flow metering can be expensive and mother nature does not always cooperate with providing good rainfall events. So it is...
