Rivertech Inc. is a professional engineering corporation providing services in urban runoff water quality control, river engineering, hydraulics, hydrology and sedimentation engineering.  Since our establishment in 1983, Rivertech has consistently provided high quality service and insures superior quality by the close involvement of the principal engineers in all stages of project development.

Professional Qualifications

The engineers of Rivertech have extensive experience, excellent qualifications and advanced degrees in hydraulics and hydrology.  Their contributions as research specialists, instructors and consultants in engineering have been substantial and provide unique qualifications in water resources engineering.  The engineers are supported by a highly trained technical staff, which insures prompt, accurate completion of Rivertech's projects within a specified budget and time.


Rivertech is experienced in many branch areas of hydraulics and hydrology including sedimentation engineering, river mechanics, river morphology, hydrodynamic analysis of estuaries and wetlands, hydraulic design of flood control structures and channels, flood and sediment routings, reservoir operation and optimization studies, watershed yield studies, detention basin design and flood plain analysis.

Major urban runoff and drainage studies completed by Rivertech include: Master Drainage and Runoff Management Plan (MDRMP) for The Irvine Company's Newport Coast Development.  As a follow-up to the MDRMP, Rivertech designed major storm drains, riparian corridors, fourteen detention and sediment balance basins and a 5-year water quality monitoring program.  Since the National Pollutant Discharge Elimination System (NPDES) storm water regulations went into effect, Rivertech has prepared many Storm water Pollution Prevention Plans (SWPPP) for planned developments and recycling plants.  In 1992, in compliance with the requirements of the State of California Coastal Commission, Rivertech prepared the Policies and Procedures for Managing Runoff from 12 project sites owned by The Irvine Company.  The 12 project sites are located in the vicinity of and drain into Newport Bay, an ecological preserve.

Rivertech's experience in wetland restoration and enhancement is second to none.  Rivertech has received the Merit Award from the American Society of Landscape Architects for developing a functional plan for Ballona Wetland.  The plan was developed for the National Audubon Society.  Other wetlands for which Rivertech engineers have developed Operation and Maintenance Manual and restoration plans are: Los Aliso Wetlands, Hayward Marsh Expansion, Mason Regional Park wetlands, Santa Ana River Marsh and Carpenteria Marsh.

Rivertech has gained recognition in analyzing the mechanics of rivers and conducting sediment transportation analyses.  Major streams and rivers for which Rivertech has performed alluvial analyses include: Santa Ana River at Riverside Narrows, Santa Clara River at White Canyon Road in North Los Angeles County, Lower Aliso Creek in Orange County, Magnesia Springs Wash in Riverside County and Carmel River in Monterey County.  Currently, Rivertech is studying the erosion/deposition processes as well as the instability of English Canyon Creek in the City of Mission Viejo.

Rivertech frequently uses the U.S. Army Corps of Engineers HEC-HMS, HEC-RAS and HEC-6 computer models, Watershed Modeling System (WMS) and Southern California hydrologic models.  Rivertech utilizes innovative technology to attain the most cost-effective solutions for our clients.
