Continuing Education Information
This webinar is open to the public and is designed to qualify for 6.5 PDHs for professional engineers and 6.5 HSW continuing education hours for landscape architects in all states that allow this learning method. Please refer to specific state rules to determine eligibility.
HalfMoon Education is an approved continuing education sponsor for engineers in Florida (Provider License No: CEA362), Indiana (License No. CE21700059), Maryland, and New Jersey (Approval No. 24GP00049300). HalfMoon Education is deemed an approved continuing education sponsor for New York engineers, landscape architects and geologists via its registration with the Landscape Architecture Continuing Education System (Regulations of the Commissioner §68.14(i)(2)). Other states do not preapprove continuing education providers or courses.
The Landscape Architecture Continuing Education System has approved this course for 6.5 HSW PDHs. Only full participation is reportable to the LA CES.
The Association of State Floodplain Managers has approved this course for 6.5 CECs for floodplain managers.
*This webinar may offer up to 6.5 PDHs to licensed geologists in some states. HalfMoon Education has not applied for state geologist continuing education approval in states requiring such.
Attendance will be monitored, and attendance certificates will be available after the webinar for those who attend the entire course and score a minimum 80% on the quiz that follows the course (multiple attempts allowed).

Speakers
Venkatesh Merwade, Ph.D.
Professor in the Lyles School of Civil Engineering at Purdue UniversityMr. Merwade he has been a professor in the Lyles School of Civil and Construction Engineering at Purdue University since 2006. During 2004 – 2006, he worked as worked as post-doctoral fellow at the Center for Research in Water Resources at the University of Texas at Austin. Dr. Merwade received his bachelor of Engineering degree in Environmental Engineering from Shivaji University, India, in 1997, his M.Sc. degree in Engineering Hydrology from University of Galway, Ireland, in 2000, and his Ph.D. degree in Civil Engineering from the University of Texas at Austin, in 2004. From 1997-1999, he worked as project engineer at Montgomery Watson (now part of Stantec) in Mumbai, India.
His research and teaching interests include surface water hydrology with specific focus on flood modeling and mapping. Much of his work has been on improving the simulation of hydrologic processes for flood prediction by using geographic information systems (GIS), data-driven techniques and advances in cyberinfrastructure. He has authored more than 100 peer-reviewed journal articles and conference proceedings in the area of river channels, watershed hydrology and flood modeling.
Some of his awards include the Education and Public Service Award (2025) from the Universities Council on Water Resources, the Education and Outreach Award (2024) from the Indiana Association for Floodplain and Stormwater Management, Best Technical Paper Award (2024) from ASCE’s Journal of Hydrologic Engineering, Outstanding Achievement Award (2018) from the Indiana Water Resources Association for work related to flood prediction and mapping for Indiana streams, and Excellence in GIS Award (2017) from Indiana Geographic Information Council for Soil-Based Floodplain Maps for Indiana.
Dr. Merwade disseminates his educational material as online tutorials, modules and YouTube videos, which have been used/viewed by hundreds of thousands of students, faculty and working professionals around the world who want to learn about hydrology, GIS applications, and hydrologic modeling.
