Description: This webinar gives an overview of the NRCS CN (curve number) method for estimating watershed runoff volumes. Topics include (1) rainfall characteristics and sources, (2) basic watershed characteristics, (3) the NRCS CN method runoff equations, (4) extreme event runoff calculations and (5) small event runoff calculations. It is expected that participants will (1) learn how to select design rainfall from reliable sources, (2) delineate a watershed, (3) delineate a flow path, (4) categorize soils, land use and land cover for a drainage area and (5) compute runoff volumes from large and small rainfall events using the NRCS CN method.
Speaker: THOMAS A. SEYBERT, PE, Ph.D. is Professor Emeritus of Engineering at Penn State Wilkes-Barre. While teaching at Penn State Wilkes-Barre, he was responsible for the delivery of the stormwater management and land development design courses in the baccalaureate surveying program. He was also responsible for the introductory course in surveying taught to both associate and baccalaureate degree students. His research and consulting interests include mitigation of stormwater runoff issues and watershed protection planning. He is the author of the book “Stormwater Management for Land Development Design.” He is actively involved in continuing and distance education efforts in both surveying and engineering. He has participated in the annual Pennsylvania Surveyors' Conference since 1991 and he is the current chairperson of the annual Penn State short course "Computational Methods in Stormwater Management." He received his B.S., M.S. and Ph.D. degrees in Civil Engineering from Penn State. He is a registered professional engineer in Pennsylvania.
