Balancing the Water Budget of a Stormwater Treatment Practice

COURSE DESCRIPTION

The performance of stormwater treatment practices is often measured by monitoring the response of the practice to natural rainfall and runoff events. For accurate performance calculations, it is essential to correctly measure the movement of water through the treatment practice. Accounting for all the inputs, outputs, and storage within a treatment practice is called balancing the water budget, and just like cash, it’s important to count every drop.

Join returning speaker Andrew Erickson, Ph.D., P.E., as we walk step-by-step through specific techniques, methods, and devices to measure or estimate the water budget components in a stormwater treatment practice

Generally for a stormwater monitoring program, the guidance provided in this online training webinar will cover open channel flow (weirs, flumes, AV meters); pipe/conduit flow; infiltration measurements, rainfall measurements, and how to handle evapotranspiration. Each of these components has uncertainty, but a simple understanding of the limitations can go a long way in reducing this uncertainty and improving accuracy. Erickson will describe specific devices (e.g., double ring infiltrometer, H Flumes, etc.) as well as general methods (v-notch weir equations) with examples for how these were used in field monitoring or measurement of water budget components.

This webinar will be especially useful for any stormwater professional that is measuring stormwater in the field (i.e., monitoring) because without accurate flow or water budget measurements, water quality calculations such as load reductions are useless.

Learning Objectives
Attendees can expect the discussion and education of the following learning objectives:

  • List and describe the components of a water budget for a stormwater treatment practice, including rainfall, open channel flow, overland flow, infiltration, evapotranspiration, change in storage, etc.
  • Explain accurate measurement or estimation techniques for water budget components, which are essential for accurate calculations of performance.
  • Compare different methods for measuring open channel flow, including primary devices (pressure sensors, bubblers, ultrasonic) and secondary devices (weirs, flumes, etc.), as well as select the most appropriate method for different situations.
  • Recognize the variation in infiltration rates throughout a treatment practice, and calculate the number of measurements required.
  • Identify potential sources of error in measurements and estimation techniques.
