<br />GERALD A. GIBBENS <br /> <br />Page 2 <br /> <br />Sear-Brown Group <br /> <br />Performed work in water resources, hydraulics and hydrology. Specific activities included: <br /> <br />· Plan and design drainage facilities for mining areas covered under the EPA Superfund <br />project. Performed basin hydrology and flood routing, relocation and rehabilitation of <br />natural streams, design detention and retention ponds and developed networks of <br />wasterock pile runoff collection ditches. Prepared conceptual and final design packages, <br />including plans, specifications, and reports. <br />. Prepared master drainage reports for communities along the Colorado Front Rangc. <br />Water surface profiling programs, rainfall hydrograph packages and runoff routing <br />programs are used to analyze current drainage patterns, flood inundation areas and <br />hydraulic performance of culverts, channels and detention areas. Conceptual levcl <br />designs, policy statements and regulations are then prepared to control development <br />within the study area. Exhibits and written documents were prepared. <br />· Performed engineering analysis of hydrologic and hydraulic features for various projects, <br />including irrigation canal structures, culverts, storm sewers, open channels, regional <br />detention facilities and other structures. <br />· Aided in the duties of Town Engineer for small communities along the Colorado Front <br />Range. Duties included construction submittal review, providing technical assistance to <br />Town technicians in operation and maintenance of facilities, and providing technical <br />assistance and making recommendations to Town Administrators and councils regarding <br />water resources planning and decision making. <br /> <br />Natural Resources Consulting Engineers, Inc.. <br /> <br />Performed work in water resources and irrigation engineering. Specific activities included: <br /> <br />. Performed final designs of reinforced-concrete irrigation facilities and measurement <br />structures, irrigation pipelines, and irrigation canal rehabilitation. Water-surface profiling <br />programs, spreadsheets and design software were used to determine existing and <br />proposed hydraulic characteristics of canals, structures, and pipelines. Construction <br />drawings, technical specifications and contract documents were prepared. On-site quality <br />control inspection and contract administration was carried out fDr designs. <br />· Prepared conceptual and feasibility level designs of new irrigation projects and <br />reconfiguration of existing projects, including determination of potential irrigable lands, <br />available water supply, crop water requirements and diversion requirements to size <br />project facilities. Reservoirs, canals, pumping facilities, delivery pipelines and on-farm <br />irrigation systems were designed. Spreadsheet models were developed to simulate project <br />operations. Capital costs and operating costs were estimated. Technical reports were <br />written documenting designs. <br />· Performed assessments and evaluations of existing irrigation systems, irrigation facilities, <br />and on-farm practices, and their impacts on basin hydrology. Information was used for <br />determination of assessments and for preparing project-specific and basin-wide <br />rehabilitationa.Ild bettt;Iment plans. <br /> <br />ltl[);\J (GO.1"ETfV W,!l.T50N <br /> <br />11II!:l <br />rt;'"ll'';p <br />~~\ft'k <br />
