86-68210 Water Resources Planning and Operations Support Group

Tom Bellinger, Acting Manager (tbellinger@do.usbr.gov)

The Water Resources Planning and Operations Support Group provides technical services to decision makers on water resources planning, reservoir and river system operations, water supply issues, surface water and ground water uses, water quality issues, watershed hydrology and water and land resources development and suitability assessments.

The professional staff includes hydraulic engineers, hydrologists, agricultural engineers, environmental engineers, geologists, physical scientists, and engineering technicians.

86-8220 Environmental Applications

Chris Holdren ( choldren@do.usbr.gov )
Our staff cooperates with local, State and other Federal agencies, and some foreign governments, as well as with our field and regional offices to help provide a better understanding of ecosystems and their functions on Reclamation projects for:

86-68240 Sedimentation and River Hydraulics Group

Timothy Randle, Manager (trandle@do.usbr.gov)

This group conducts studies on how rivers and reservoirs respond to various actions through changes in riverflow, sediment supply, or channel modification. These studies are prepared for a variety of purposes including operation and maintenance of facilities and reservoirs, fish and wildlife habitat restoration, and water conveyance. The group also prepares dam break inundation studies and maps which are used for emergency planning, hazard classification, and for guiding the selection of risk reduction alternatives at unsafe dams.

86-68250 Flood Hydrology and Meterology Group

Bob Swain, Acting Manager (rswain@do.usbr.gov)

The group consists of hydraulic engineers and meteorologists. Representative activities in dam safety are listed below:

PROBABLE MAXIMUM PRECIPITATION (PMP). Meteorologists, using the latest hydrometeorological reports of the National Weather Service, determine probable maximum precipitation amounts for appropriate storm durations, for both general and local storms, at any location in the United States.
DESIGN FLOOD HYDROGRAPHS. Hydraulic engineers, using the PMP amounts and the hydrologic characteristics of the basins (including snowmelt if applicable), compute probable maximum floods (PMF) for basins ranging in size from less than one square mile up to thousands of square miles. These floods are used to determine the hydrologic adequacy of a dam and to design structural modifications and/or early warning systems if necessary. Smaller design floods can also be computed.
FLOOD FREQUENCY STUDIES. Using available streamflow records and the latest acceptable analytical techniques, engineers derive flood frequency curves at specific points on a stream. Regionalized analyses can also be done. EARLY WARNING SYSTEMS (EWS) EVALUATION. Staff analyze design storms and physical characteristics of dams and downstream areas to determine the feasibility of an early warning system to provide adequate warning time to the population-at-risk from flooding in the event of hydrologic failure of a dam.
EARLY WARNING SYSTEM DESIGN. If an early warning system will provide adequate warning time to threatened populations, staff can design a system of hardware, software, and communications equipment to detect potential flood events and warn appropriate emergency management personnel. Staff also install and help maintain EWS equipment.

86-68270 Economics and Resource Planning Group

Rick Vinton, Manager, (rvinton@do.usbr.gov)

We provide a wide range of expertise in water resource-related planning, economic and financial analyses, recreation, cultural resources, multidisciplinary team management, public involvement, conflict resolution, social analysis, facilitation, and conference planning. We also perform studies and provides support in project planning and evaluation and for National Environmental Policy Act (NEPA) compliance activities. A few of the projects being conducted include support of Truckee River Operating Agreement activities; public involvement, social analysis, recreation evaluation, economics and financial analyses for the planning report/EIS for the Yakima River Basin Water Storage project; economic cost, lost benefit, and repayment evaluations for Safety of Dams studies; and hydropower valuation for Colorado River studies.

86-8290 The Fisheries and Wildlife Resources Group

Steve Hiebert, Group Manager, shiebert@do.usbr.gov

The Fisheries and Wildlife Resources Group combines the expertise of professional fisheries scientists, wildlife biologists, environmental regulatory specialists, and environmental chemists, to conduct a wide variety of multidisciplinary environmental field and laboratory studies concerning aquatic and terrestrial habitats, wildlife, water quality, and environmental impacts.
