BILLY H. JOHNSON, PHD, PE, D.WRE <br /> COMPUTATIONAL HYDRAULICS& TRANPORTLLC <br /> Dr. Billy Johnson has over 40 years of experience in developing and applying numerical <br /> models to address various types of water resources problems. He retired from the US <br /> Army Engineer Waterways Experiment Station (WES) in 2001 after more than 30 years <br /> of service. During his 30 years at WES, he was involved in developing models such as <br /> FLOWSED (11) unsteady river model), LAEMSED (2D laterally-averaged flow and <br /> sediment transport), CH31) (curvilinear hydrodynamics in three-dimensions), STFATE <br /> (short-term fate of dredged material disposed in open water), and SSFATE (suspended <br /> sediment fate of material re-suspended at the dredging site). He introduced the concept of <br /> generalized curvilinear coordinates in numerical hydrodynamic modeling in the late <br /> 1970's —early 1980's. His expertise in the development and application of advanced <br /> numerical modeling tools is reflected through the many awards he received during his <br /> federal career.These include WES Engineer of the Year 1989, Mississippi ASCE <br /> Hydraulic Engineer of the Year 1990, Department of the Army Research and <br /> Development Award 1991, Associate Editor of ASCE Journal of Hydraulic Engineering <br /> 1993-97, and the EPA National Science Award in Water.Quality Modeling 1999. In 2005 <br /> he was inducted into the WES Gallery of Distinguished Employees and into the <br /> American Academy of Water Resource Engineers as a Diplomate He is the author of over <br /> 100 technical reports, conference proceedings, book chapters, and journal articles. <br /> EDUCATION <br /> Bachelor of Science, Aerospace Engineering, MS State University, 1967 <br /> Master of Science, Aerospace Engineering, MS State University, 1968 <br /> Doctor of Philosophy, General Engineering, MS State University, 1971 <br /> REGISTRATIONS <br /> Registered Professional Civil Engineer; No. 12078 MS 1992 <br /> Diplomate ASCE Water Resources Engineering 2005 <br /> PROFESSIONAL ORGANIZATIONS <br /> ASCE <br /> SELECTED PROJECT EXPERIENCE <br /> Technical Review <br /> Technical review of the hydrodynamic component of various studies has been performed. <br /> Examples include several minimum flow and levels studies for rivers located in the <br /> Southwest Florida Water Management District, water quality modeling of Florida Bay for <br /> the South Florida Water Management District, and water quality modeling of Indian <br /> River for the St. John's Water Management District. <br /> Development of 3D Hydrodynamic Model of Chesapeake Bay <br /> A 3D hydrodynamic model of Chesapeake Bay to provide flow fields to the 3D <br /> CEQUAL-ICM water quality model was developed. The development of the Z-plane <br /> version of CH31)was required for the computation of a flow field that remained stratified <br /> Billy H,Johnson <br />
