Bridge the gap between hydrologic theory and practical application to build robust watershed models for flood control and stormwater analysis.

Master the fundamentals of hydrologic modeling with our comprehensive course, Introduction to HEC-HMS Modeling. Developed by the U.S. Army Corps of Engineers, the Hydrologic Modeling System (HEC-HMS) is an industry-standard software designed to simulate the complete precipitation-runoff processes of dendritic watershed systems. This course bridges the gap between hydrologic theory and practical application, empowering professionals to perform accurate water resource studies essential for floodplain management, dam safety, and infrastructure design.
This course is designed for engineers, landscape architects, and hydrologists seeking to build confidence in using HEC-HMS for real-world scenarios.
By the end of this session, you will be equipped with the skills to:
Whether you are new to the software or looking to refresh your knowledge of version 4.12 features, this course provides the technical foundation necessary to produce reliable hydrologic models and defensible engineering data.

Principal and Owner of Rippled Waters Engineering, LLC
Ms. Paist-Goldman has more than 20 years of experience in water resource engineering with a particular focus in stream and wetland restoration and mitigation design. She is the principal and owner of Rippled Waters Engineering, LLC, based in New Jersey. Her firm specializes in water resources engineering services for a variety of projects. Prior to starting Rippled Waters in 2018, she served for many years as principal engineer and director of Engineering Services of a Mid-Atlantic regional natural resources firm. She is an experienced modeler and has worked extensively on design and analysis using a variety of hydrologic and hydraulic programs including HEC-HMS, HEC-RAS, and HydroCAD. Applications for her hydraulic modeling expertise include wetland restoration and mitigation; stream restoration; bridge repair and replacement; and dam repair, replacement, and removal. Specifically related to riverine systems, Ms. Paist-Goldman has extensive expertise with stream restoration, large woody debris, natural channel design and bioengineering stabilization techniques. Ms. Paist-Goldman has designed restoration projects of all sizes ranging from a few hundred feet to several miles of stream. These projects are planned for use as mitigation banks or serve as mitigation for development onsite. Working closely with restoration ecologists and landscape architects, Ms. Paist-Goldman has designed a variety of stream and wetland habitats including creation, enhancement, restoration, and preservation with a focus on sustainability and regulatory compliance.
