397726 - Instrumentation, Lessons Learned, and Benefits from Hydraulic Monitoring of Urban SMPs

Tuesday, June 5
10:30 AM - 12:00 PM
Location: Greenway AB

Accurately monitoring stormwater management practices (SMPs) in the urban environment is extremely difficult because conditions are variable, space is limited, there is the potential for vandalism, and the challenge of disrupting the normal flow of urban life. Villanova University is intensively monitoring stormwater sites in Philadelphia with the assistance of PennDOT, AECOM, Temple University, and the Philadelphia Water Department (PWD). This presentation focuses on selecting the most appropriate and accurate monitoring equipment for urban conditions, analyzing their function within urban environments, and the benefits of monitoring urban stormwater site designs.
The presentation will first review the instrumentation design for two case studies. One study comprises two PWD rain gardens in series capturing surface street runoff built part of Philadelphia’s Green City, Clean Waters. The other design is five linear bioswales built as part of the Interstate-95 Girard Avenue Reconstruction project in Philadelphia. The five linear bioswale are capturing runoff from an adjacent elevated highway. Instrumentation selection is dependent on the site design and conditions, and as a result, there are substantial differences between the two sites. The instrumentation design includes meteorological parameters, inflow and outflow measurements, level depths and soil moisture. Specific focus will be as to what sensor configurations and measurement accuracy and levels were chosen to capture the performance and lessons learned to implement in future instrumentation designs.
Additionally, the presentation will discuss the monitoring results and expand on the value of field testing through Simulated Runoff Tests (SRTs). The field tests are a way to test monitoring equipment under controlled conditions and also evaluate the performance of these infiltration systems in an ultra-urban environment. Review of performance will include soil water interactions and review of design expectation. Furthermore, an important result of the monitoring has been its use of a tool for inspection. From drainage areas to underdrain leaks, overflow elevations, and infiltration capacity, the monitoring system has proven to be a valuable asset in testing the components of Stormwater Management Practices.

Dr. Robert G. Traver has been a member of the Water Resources Program at Villanova since 1988. He is the Daylor Chair in Civil Engineering, and he currently serves as Director the Villanova Center for Resielent Water Systems.

While at Villanova Dr. Traver has conducted research on topics that include modeling of stream hydraulics, urban hydrology, water quality, and measures to mitigate stormwater effects of urbanization. He has been the main force in creating a Stormwater Green Infrastructure Demonstration and Research Park on the Villanova Campus, and founded the Villanova Urban Stormwater Partnership. Many highly cited publications have resulted from the faculty and students through this initiative. Dr Traver believes that research supports and enhances the undergraduate and graduate educational experience.

Dr. Traver is a registered professional engineer, a fellow of the American Society of Civil Engineering (ASCE), and a Diplomate of the American Academy of Water Resource Engineers which he served as president. In 2007 he received the Outstanding Civilian Service Medal from the Commanding General of the Unites States Corps of Engineers for his work on ASCE’s External Review Panel (ERP) of the Corps investigation of Hurricane Katrina and in 2014 was honored as the ASCE William H. Wisley American Civil Engineer Award “recognized for his leadership of ASCE’s Task Committee on Flood Safety Policies and Practices and editor of the Committee’s report, Flood Risk Management: Call for a National Strategy.” He was a committee member of the National Research Council Committee that authored “Urban Stormwater Management in the United States” (2009). He continues to serve the profession as an associate editor of the ASCE Journal Sustainable Water in the Build Environment which he helped to create.
