Katelyn Costanza, Principal Engineer
Mrs. Katelyn Costanza is a Licensed Professional Engineer and Certified Floodplain Manager (CFM) with more than 15 years of experience. She has managed various United States Army Corps of Engineers Civil Works projects and programs and provided nationally recognized technical expertise to the National Oceanic and Atmospheric Administration’s National Weather Service. Mrs. Costanza is nationally recognized for making significant advancements to the National Weather Service’s hydrologic program. She played an integral role in performing hydraulic and hydrologic modeling and implementing numerical routing techniques which enhanced the federal government’s mission to provide flood and drought decision support on the Lower Mississippi River Basin. She has led various interdisciplinary technical teams including the NWS’s Southern Region Flood Inundation Mapping Program. She has presented at international conferences including the 2015 European Geophysical Union (EGU) held in Vienna, Austria for her work in developing a forecasting and information system for water level, salinity, temperature and sediment fate and transport for Coastal Louisiana.

Dr. Fei Xing, PhD, Lead Scientist
Dr. Xing has more than nine years of experience in coastal hydrodynamics and sedimentology specialized in numerical modeling of extreme events, coastal morphology, and restoration alternative analyses. She has used multiple coastal engineering softwares, such as DELFT3D, SWAN, MIKE21 and is proficient in Fortran, MATLAB, ArcGIS and Unix Shell scripting. Her project experience includes evaluation of the sediment dynamics of the Lower Song Hau Channel in Vietnam for the Office of Naval Research and model coupling to evaluate the interaction between flow-morphology-water quality-vegetation in the Mississippi River Delta in support of the Mississippi River Hydrodynamics and Delta Management Feasibility Study. Dr. Xing also has studied hurricane and cold fronts on the Wax Lake Delta for the National Science Foundation, for which she has contributed to the advancement of numerical modeling by developing a sub-routine used in Delft 3D, and evaluated the roles of hurricane and cold fronts on delta morphology. Dr. Xing also has some hydrological modeling experience by using HydroTrend to study the long-term hydrological changes for the Ebro Delta in Spain, and participating in a subroutine development for the Distributed Large Basin Runoff Model at NOAA. Dr. Xing has presented at many international conferences, such as American Geophysical Union and International Conference on Tidal Environments, and published more than 10 scientific papers on peer-reviewed journals.

Raymond 'Jason' Caldwell, PhD, PE, CCM, Principal Hydrometeorologist
Dr. Caldwell is a Licensed Professional Engineer (WY) and Certified Consulting Meteorologist (CCM) with over 20 years of experience in meteorology, hydrology, and statistics. Jason received his PhD in Civil Engineering from University of Colorado in 2013, following undergraduate/graduate work in Meteorology.
Jason has served as the technical lead on projects for the National Weather Service, U.S. Army Corps of Engineers, Reclamation, BC Hydro, and Tennessee Valley Authority. He has contributed significant improvements to: data QA/QC; quantitative precipitation estimates (QPE); extreme precipitation studies (PMP and Regional Frequency Analysis); and, stochastic modeling in the dam and nuclear safety arenas.
In addition, he has participated on the Extreme Storm Events Working Group at the federal level, presenting work from Reclamation at the Nuclear Regulatory Commission's Probabilistic Flood Hazards Workshop in 2013. He is a member of and presents regularly at conferences including Annual Meetings of the American Geophysical Union, American Meteorological Society, U.S. Society of Dams, and Association of State Dam Safety Officials.
