Wetland Restoration
and Management We have many years of experience in the planning and
detailed conceptual design of wetland restoration projects. This has included
measurement of tide heights and derivation of local tidal datums, modeling of
tidal circulation in muted tidal wetlands to predict modified tidal regimes,
modeling the accumulation of fine sediment in marshes, developing geomorphic
relationships for use in channel design, and assisting clients with permitting
problems.

Watershed Management and Water Quality Watershed management draws not
only on the disciplines of hydrology and geomorphology, but also on
biogeochemistry. We have many years of experience in evaluating effects of land
management on stream nutrient loads, water quality, erosion and sedimentation.
We work closely with geomorphologists to develop plans and programs for
controlling sediment and temperature impacts of land management.

Stream
Restoration and Management Our experience in stream restoration and management
includes developing enhancement plans for urban streams, contributing to
Environmental Impact Reports, determining the limits of "Ordinary High Water",
and helping clients with difficult permitting and compliance issues. Our
Affiliated Staff includes a water resources engineer and a fisheries biologist,
giving us the full range of expertise and experience needed to tackle complex
hydraulic and aquatic habitat problems.

Limnology and Lake
Management We have worked on a wide variety of lakes in
California, include Lake Tahoe, a mid-elevation lake in the Sierra Nevada, and
saline recreational lakes around San Francisco Bay. Problems addressed include
impacts of climate change on lake thermal structure, accelerated eutrophication
associated with watershed development and urban runoff, microbiological effects
of recreational use, and sedimentation. On these projects, we collaborate
closely with biologists and water resource engineers, who apply numerical
models to analyze lake circulation problems.
