Russian River Projects

GEOMORPHIC ANALYSIS OF THE MIDDLE REACH OF THE RUSSIAN RIVER
Waterways, in cooperation with Swanson Hydrology and Geomorphology, is in the process of completing a detailed hydraulic, geomorphic and sediment transport analyses for the Russian River’s Middle Reach, near Healdsburg. This work focuses on the effects of in-stream mining and other human activities on channel morphology and flood capacity. A chrono-sequence of topographic surfaces representing the channel and floodplain were analyzed to calculate volumetric changes in channel geometry over the past 20 years. Then, a hydraulic model was constructed along 5 miles of the Russian River to evaluate land use impacts on flood elevations.

GEOMORPHIC AND HYDRAULIC ANALYSIS OF THE ALEXANDER VALLEY REACH OF THE RUSSIAN RIVER
Waterways, in cooperation with Swanson Hydrology and Geomorphology, was hired by Syar Industries to interpret the geomorphic and hydraulic conditions of the Lower Alexander Valley and to develop recommendations for a mining plan that is economically feasible, environmentally sensitive, and consistent with the Sonoma County ARM Plan’s objective to “balance extraction to reflect natural recharge levels, provide high-quality aggregate materials, and protect fisheries [and] wildlife habitat”. The intent is to describe the geomorphology of the system, summarize the results of the analyses, and recommend a sustainable plan for in-stream mining, given our understanding of the system. Waterways also compared a mining plan that adheres to the ARM Plan policies and operating standards to a recommended plan that includes opportunities for resource enhancements, including terrace skimming to restore flood plain and conditions for colonization of native riparian vegetation species and the eradication of selected stands of Arundo donax and in-stream aquatic habitat creation (alcoves, etc.).

MIDDLE REACH PIT RECLAMATION ALTERNATIVES
Waterways has been hired by Syar Industries to perform hydrologic and hydraulic modeling and design of alternative Pit Reclamation Scenarios. The alternatives would provide a long term hydraulic connection between the reclaimed pits and the Russian River, allowing opportunities for the development off-channel salmonid habitat and reducing the potential for catastrophic breaching or “pit capture” by the Russian River.
