Speakers
Andres Salazar
Walter P MooreDirector of Water Resources Engineering for Walter P MooreDr. Salazar serves as the director of water resources engineering for Walter P Moore. He is a water resources engineer with more than 17 years of experience in steady and unsteady modeling, river basin and reservoir operations, and water resources planning. Dr. Salazar is an expert with planning and feasibility studies for drainage and water supply projects. He has extensive experience with complex drainage projects across the State of Texas and is proficient in the use of EPA-SWMM, HEC-RAS, HEC-HMS, STORM NET, InfoWorks, and RiverWare computer models. Dr. Salazar has special expertise in hydrologic and hydraulic systems that are key to creating an effective sustainable site drainage design. Dr. Salazar provides expertise and direction for site drainage, water recycling, and site water amenities. He joined Walter P Moore in 2009.
Andrew Yung
Walter P MooreChief Hydrologist for Walter P MooreMr. Yung serves as chief hydrologist for Walter P Moore. Mr. Yung has more than 27 years of experience as an engineer, planner, and hydrologist. He has managed a wide range of engineering projects involving hydrology, hydraulics, master drainage studies, channel modification and hydraulic structure designs, watershed impact analyses, detention facility designs,and dam safety analyses. Mr. Yung has also served as the team leader for independent technical review (ITR) for several federal projects currently under way in Houston. He is very familiar with HEC-HMS/ HEC-1, HEC-RAS/HEC-2, HEC-DSS, and HEC-SSP and provides technical support and training tousers of these programs. Mr. Yung joined Walter P Moore in 1996.
