Chris Goodell, P.E., D.WRE

Principal Consultant, Hydrology and Hydraulics, Kleinschmidt

With more than 25 years of experience in water resource hydraulic engineering, Chris is considered an expert in the field. His expertise includes hydraulic modeling, dam break studies, sediment transport, bridge, and culvert design, inundation mapping, and software development/design.

Chris is an internationally known leader in HEC-RAS modeling with a particular interest in risk-based solutions for hydraulic modeling. He has taught over 100 professional education courses on HEC-RAS around the United States and on 5 continents. Chris is the developer and primary author of “The RAS Solution”, an HEC-RAS blog, and the author of the book “Breaking the HEC-RAS Code.” He also developed McBreach, a software program that runs HEC-RAS dam breach models in a probabilistic framework. McBreach was released to the public in 2019 and is currently being used across the globe. He has been extensively published and presented technical articles at numerous industry conferences. He was also a contributing author for the HEC-RAS Hydraulic Reference Manual and the HEC-RAS User’s Manual for version 3.1. He is an instructor in the Kleinschmidt HEC-RAS Webinar series, and he is the co-creator of Full Momentum- an HEC-RAS Vodcast.

Chris holds an M.Eng. in Hydraulic Engineering from IHE-Delft in The Netherlands, as well as a B.S. in Civil Engineering from Oregon State University. He is an active member of the United States Society on Dams (USSD), the Association of Dam Safety Officials (ASDSO), the American Society of Civil Engineers (ASCE), and the American Academy of Water Resource Engineers (AAWRE). 

Ben Cary, P.E., CFM

Hydraulic Engineer, Kleinschmidt

Ben specializes in 1D and 2D hydraulic modeling, hydrological engineering, dam breach analysis, and river restoration.  He builds hydraulic models to simulate open channel flow through rivers to evaluate areas of inundation caused by potential flooding of dam breaches; conducts hydraulic calculations through pipes and over dams or other structures to develop stage-discharge rating curves and gate capacities, and creates energy models to determine historical and potential generation based on potential facility upgrades or improvements.

Ben routinely uses HEC-RAS 1D Steady/Unsteady, HEC-RAS 2D, XP SWMM 2D, FLO 2D, and Arc GIS for modeling and to provide spatial reference and analysis. Some of his most recent assignments with Kleinschmidt include working on Hydraulic Modeling, Dam Decommissioning Analysis, and CLOMR Application; Hydrological Analysis; Flood Modeling; Hydraulic Analysis and Modeling of Proposed Changes to Reservoir Operations.

Ben has a B.S. in Civil Engineering from Gonzaga University and is an active member of the American Society of Civil Engineers (ASCE), and River Restoration Northwest (RRNW). He is an instructor in the Kleinschmidt HEC-RAS Webinar series, and he is the co-creator of Full Momentum- an HEC-RAS Vodcast. Ben is a licensed Professional Engineer in the state of Oregon and a Certified Floodplain Manager.

Sr. Business Class Leader & Principal, HDR

Mark is a Senior Business Class Leader (Surface Water Hydrology and Hydraulics and Floodplain Management) and is a Principal Professional Associate for HDR.  He has over 40 years of experience in hydrologic and hydraulic modeling, floodplain management, and water resources engineering.  As the Senior Business Class Leader for Surface Water Modeling and Floodplain Management and Principal Professional Associate for HDR, he is responsible for the development of technical best practices and training in these disciplines, oversight of the Surface Water Modeling Practice Group, and providing technical leadership and risk management on projects involving floodplain analysis, regulatory compliance, and hydrologic and hydraulic modeling.  Mark also performs training courses on hydrologic and hydraulic modeling and floodplain management within HDR and has performed HEC-RAS 2D analysis training both internally and externally to HDR clients and at technical society conferences in the U.S. and Australia.

Mark also has project experience working on many projects in the Northwest, including several in the Treasure Valley on the Boise River and in Caldwell, Idaho. 

Karl Gebhardt, P.E.

Engineer & Hydrologist, Resource Systems

Professional Engineer and Professional Hydrologist, Resource Systems, Inc. 1982 – Present. BS Civil Engineering University of Utah, MS Environmental Engineering Utah State University – emphasis on ecology. Formulated or designed many of the riverside habitat and floodplain modification and side channel projects on the Boise River including Barber Pool, Spring Meadows, Marianne Williams Park, Harris Ranch, Eagle Island, Mace Ranch, Three Rivers Ranch, and others. Project leader for the 1983 Boise River Fish and Wildlife Habitat Study that served as the basis for the Boise River Plan and Ordinance.

Prepared over 100 wetland delineations and successful permits under section 404 of the Clean Water Act. Completed over 50 FEMA flood mapping revisions, including some of the first 2D revisions approved by FEMA. Authored/co-authored publications on sediment and erosion methods, Proper Functioning Condition (PFC), Ecological Site Investigation (ESI), Riparian Classification, and Watershed Analysis (USFS). Currently serving on the Harris Ranch Wildlife Mitigation Board and Barber Pool Technical Advisory Committee. Founding Member of Boise River Enhancement Network, Founding Organizer of Idaho Northwest Regional Floodplain Managers Association Idaho Technical Committee, Founding Organizer of Idaho Water Quality Workshop (1990), Founding Organizer Boise River 2000.

Ron Manning, M.S., P.E, CFM

Hydraulics Manager, Forsgren Associates

Ron has over a decade of hydrologic, hydraulic, flood risk analysis, and permitting experience. Ron spent years consulting with the state of California to develop 1D & 2D flood risk models for both flood analysis, planning, and response. Before moving to Idaho, Ron managed the development of a custom flood response software program using HEC-RAS, allowing first responders to input observed levee conditions and model levee breach scenarios in near real-time. The software produced custom flooding and evacuation maps to aid in flood fight and response. While in Idaho, Ron is mostly supporting floodplain development permitting and bridge hydraulic design. He has completed projects for Idaho Transportation Department (ITD), private entities, and multiple Cities and Counties.
