HEC-RAS 2D: Instructors
Patrick Miles, P.E.
Freese & Nichols, Inc.
Associate & Water Resources Engineer
With 18 years of experience, Patrick Miles serves as the H&H technical leader for Freese and Nichols’ Water Resources Design Practice. He specializes in hydrologic and hydraulic modeling for dams, levees, canals, spillways, and related structures for assessments, comprehensive reviews, rehabilitation design, Probable Maximum Flood analyses, breach analyses, and levee certifications. Patrick supports dam owners and regulatory agencies across the central and southeast United States to assess, maintain, and rehabilitate their critical infrastructure, as well as evaluate dam safety risks and strengthen emergency preparedness. His H&H modeling abilities include extensive HEC-RAS experience extending to all components of one-dimensional and two-dimensional flow, as well as utilizing corresponding GIS applications for model development, consequence assessment, and map production. Patrick has served as lead instructor for HEC-RAS 2D training courses through nationwide professional organizations and multiple state dam safety agencies since 2017. He holds a bachelor’s degree in civil engineering from Texas A&M University and is a licensed professional engineer in twelve states.
Camilo Cristancho, P.E .

Jennifer Gaines, P.E.
Freese and Nichols, Inc.
Water Resources Engineer
Jennifer Gaines is a project manager in FNI’s Atlanta office with 12 years of experience in the evaluation and design of dams in the southeast U.S. and Texas. Jennifer has performed a wide variety of hydrologic, hydraulic, geotechnical, and structural analyses related to the design of new dams and the rehabilitation of existing structures. She has experience in hydraulic and structural design of reinforced concrete spillway structures, including standard NRCS risers, chute spillways, and stepped spillways. She has extensive experience with breach inundation modeling to evaluate potential flood impacts and establish hazard classification recommendations for dams based on state-specific dam safety criteria. Jennifer is proficient in both 1D and 2D modeling within HEC-RAS, as well as the associated GIS applications for model development and inundation mapping. She holds a bachelor’s degree in civil engineering from Georgia Tech University.
