Jun Wang, P.E. <br />conducting a watershed stream -basin network modeling of Barrel Springs <br />Wash in the City of Palmdale following the Los Angeles County <br />hydrology procedure to determine the peak flow rates as well as the flood <br />hydrographs of the design event. <br />Project Manager, Amargosa Creels Hydraulics/ Sediment Transport <br />Study and Channel Improvement Design, Palmdale, CA, City of <br />Palmdale: Responsible for directing and performing channel hydraulics <br />and sediment transport analyses to develop the basis of the channel <br />improvement design for an over one mile long soil cement channel in the <br />City of Palmdale. The study involved detailed hydraulic analysis of the <br />river system using Hec -Ras and sediment transport modeling using Hec -6 <br />under a range of storm events to determine the extent of scour/ <br />deposition in the channel to facilitate the preparation of channel <br />improvement plans. <br />Project Manager, Prince Barranca Channel Improvement Design, <br />Ventura, CA, County of Ventura: Responsible for the on -going <br />preliminary design of a flood detention basin facility in the City of <br />Ventura. The project involved developing multiple drainage improvement <br />alternatives including an upstream detention for the existing Prince <br />Barranca Channel which is currently unable to carry the 100 -year flood. <br />The project involved hydrology, hydraulics, sediment yield analysis, and a <br />30% completion design of the basin facility. Flood damage analysis and <br />benefit /cost ratios were also developed to justify the flood detention <br />project. <br />Project Manager, FEMA Letter of Map Revision Study of Amatgosa <br />Creek, Palmdale, CA, City of Pahndale Public Works: Responsible <br />for developing the 100 -year floodplain map of Amargosa Creek and <br />coordinating with FEMA to obtain the Letter of Map Revision (LOMR). <br />The work was done for the Public Works Department of City of <br />Palmdale. The floodplain map was prepared based upon a Hec -Ras <br />analysis of the river's study reach and digitally using GIS -based <br />topographic information. Both FEMA standard base map and annotated <br />revised Flood Insurance Rate Map were created. The LOMR was issued <br />by FEMA within one and half months from the date of submittal. <br />Project Engineer, Drainage Study, Viejas Indian Reservation, CA, <br />Viejas Indian Tribe: In charge of conducting a drainage evaluation of <br />Viejas Indian Tribe including a floodplain analysis of Viejas Creek <br />through development of a rainfall runoff model using GeoHMS to <br />determine the 100 -year flood peaks and a HECRAS model to simulate the <br />vertical and horizontal profiles of the 100 -year flood event. The study also <br />evaluated the design adequacy of number of major drainage structures and <br />developed alternative solutions to improve the flood conveyance <br />conditions of these facilities. <br />25F -75 <br />
