Flooding is no longer a rare event; it is an increasing reality for communities across the country. New federal standards updated floodplain maps, and resilience-focused mandates are reshaping how sewer and drainage systems must be designed. Infrastructure built on outdated assumptions risks being undersized, leaving critical services, property, and public safety exposed. Join us for a complimentary webinar where we will examine how modern flo...

Join us on Tuesday, October 14 from 12:00 PM - 2:00 PM Eastern for Practical Applications of Trash Racks and Anti-Vortex Devices. This webinar will cover the effects of vortices, debris, and other issues on spillway hydraulics. Air entering the spillway through a vortex reduces the spillway discharge and increases debris management. Various drop inlet spillway designs developed over the years will be reviewed with the effects of the changes on...

Join us on Tuesday, September 9 from 12:00 PM - 2:00 PM Eastern for Getting Ahead of the Storm: Building Capacity to Respond to Large-Scale Weather-Related Dam Impacts. This webinar will discuss the lessons and expertise gained from rebuilding a state dam safety program from state dam safety program officials and emergency managers almost 10 years after a historic rainfall event that had impacts statewide and caused the failure of 50 state-reg...

This is an interactive seminar focused on the practical use and advantages of two-dimensional flow capabilities in HEC-RAS, with emphasis on applications for the dam safety industry. The course will maintain a balance between lecture-style presentations on model theory and hands-on workshop sessions for practical examples. Topics will include applications and benefits of HEC-RAS 2D modeling; RAS Mapper and terrain preparation; executing 2D mod...

The objective of this course is to provide instruction on the general subject of earthquake engineering of embankment dams. The course will begin with a historical perspective on dam performance during earthquakes and an overview of basic concepts about earthquakes. The course will then progressively address more specialized subjects including a) evaluation of seismic hazard and characterization of earthquake motions for dam design, b) field i...

This course provides an introduction of HEC-RAS with applications to dam safety. The course provides a hands-on opportunity to use the program and resolve specific questions. The objective of this course is to review the basic principles of open channel hydraulics as they relate to the natural stream environment with application to dam safety. Bridges, culverts, and in-line structures will be discussed and both steady and unsteady flow modelin...

The objective of this course will be to provide a comprehensive presentation of the significant principles and concepts of soil mechanics to the participants. The material will be presented with emphasis on the basic soil mechanics principles prerequisite to further study for the design or rehabilitation of earth embankment dams. This is a basic-level course intended as an introduction for those with minimal to moderate knowledge or experience...

Join us on Tuesday, June 10 from 12:00 PM - 2:00 PM Eastern for The Use of Void Ratio (e) in Earth Dams. Void ratio (e) is a term used extensively in soil mechanics. It is a fundamental ratio that quantifies the changes in volume taking place in a soil mass. Earthen dams are constructed with soils that hold back water over a long period of time, even though they are made of pervious materials. The embankment and foundation soils may differ in...

States, counties, municipalities, territories, and tribal governments have many interactions with their residents every year, addressing many facets of everyday life – from schools to roads, water and sewer services to business licensing. The National Association of State CIOs (NASCIO) identified the top 10 priorities of its members for 2025. While strengthening cybersecurity and risk management continues as the top priority, state CIOs...

Participants will gain a practical knowledge of methods for simulation of runoff from storm rainfall. The methods covered relate to the processing of historical and hypothetical (design-storm) rainfall data; estimation of losses (infiltration); transformation of rainfall excess to direct runoff with unit hydrographs; routing of flood waves; calibration of model parameters; and modeling of runoff from watersheds. Experience will be gained in ap...
