Online training
Feb 7 - 8, 2024

Assessing the impacts of development on downstream receiving waters requires metrics beyond mere conveyance (e.g., peak flows or velocities) or loading (e.g., peak depth or total volume). Impacts must be measured with respect to multiple design and operational objectives, including flooding/erosion hazard protection, water quality treatment, volume control, environmental flow maintenance, and climate resiliency. The overall objective is to manage stormwater in a way that mimics pre-development conditions and preserves natural flow characteristics over a wide operating range in response to land alteration or other development activities.

This specialized PCSWMM and EPA SWMM5 workshop is intended for both new and experienced modelers with the objective of building skills to evaluate development impacts using PCSWMM flow frequency and flow duration tools that characterize depth, velocity, or flowrates based on computed/measured hydrographs. These tools will be applied to conduct a hydromodification analysis that quantifies changes to channel form/stability in watercourses as well as a hydroperiod analysis that quantifies the characteristic time period during which a wetland or other waterbody is inundated with water. In addition, a climate change analysis will be included to evaluate system resiliency. Concepts will be reinforced using a series of hands-on exercises.

PCSWMM will be used throughout the workshop to speed learning and program execution and enhance understanding of the underlying EPA SWMM5 processes. Participants will develop the necessary skill and confidence to explore and apply the official EPA SWMM5 hydrology/hydraulics engine effectively. During this course you will have an opportunity to learn from a live instructor during scheduled live sessions.

You will receive full workshop details with the course login details, prior to the workshop. If you have any questions or comments, please contact our workshop coordinator.
