· Project manager for the evaluation of the hydrology, hydraulics and geomorphic
investigation of Monroe Creek near Weiser, Idaho. The investigation was completed to
provide channel relocation options to the Idaho Transportation Department. It
included the hydrologic analysis of Monroe Creek, hydraulic analysis of the study reach
including bridge designs, and a sediment transport analysis of the existing and post
construction scenarios.

· Project engineer for the preparation of a design document and manual for river training
and bank stabilization works for the Department of Transport, Papua, New Guinea. The
project involved an intensive one-month field investigation of bed, bank and bridge
stability in rivers throughout Papua, New Guinea, development of design procedures and
mitigation measures for stabilizing the erosion problems, and preparation of a manual for
selection and application of the appropriate stabilization measures.

· Principal engineer for the relocation and design of the Little Medicine Bow River in
Wyoming. The purpose of this project was to restore the river to a stable configuration
following uranium mining and the design and construction of a bridge across the river.
Responsibilities included generation of hydrologic design discharges; development of
channel hydraulics to support floodplain, sediment transport, and bridge investigations;
geomorphic evaluation of the existing river channel, watershed, and bridge location; and
generation of design parameters for the proposed channel. Sediment rating curves and
sediment continuity principles were applied to determine the impact of sediment transport
through the proposed channel realignment, bridge design, and associated hydraulic
structures.

· Project manager for the evaluation and design of two crossings on Dry Creek, located
in Cheyenne, Wyoming. This project included a hydrologic evaluation of Dry Creek to
determine the design discharge. Hydraulic evaluation of several design alternatives and
channel stability analyses were conducted.

. Project manager and engineer for the evaluation, design and construction of the Big
Goose Creek drop structure located in Sheridan, Wyoming. An existing structure built
in the 1940's created a hazard to public safety. This project involved a hydraulic
evaluation of the existing structure to determine design criteria, scour analysis of an
adjacent bridge, and hydraulic design of the replacement structure. The final design
consisted of a series of four low-drop grouted rock drop structures which eliminated the
hazardous conditions of the original structure while maintaining the integrity of its
design. Mr. Anderson managed the removal of the existing structure and the construction
of the replacement.

In completing these and other projects, Mr. Anderson has gained extensive experience
in the application of the HEC series of computer models including HEC-l, and HEC-2. His
modeling experience also includes application of the EPA SWMM model, TR20, TR55 and the
two dimensional FHWA model FESWMS. As a hydrologist, Mr. Anderson has gained
experience in deterministic, empirical and stochastic analytical techniques. This work has
commonly involved the application of procedures described in WRC Bulletin No. 17B, TP-40,
HMRSl and HMRS2.
