Merced River Robinson Reach Geotechnical Investigation

DWR proposes geotechnical exploration to collect in-situ bank material for particle-size distribution grain-size gradation testing and erodibility evaluation. Results will guide the design of subgrade layers, including geotextile fabric, for bank stabilization for the Merced River Robinson Reach Maintenance Project. Two test pits, each approximately 30 feet long, 10 feet deep, and 4 feet wide, will be excavated by backhoe along the bank’s outside edge. They will be at least 25 feet from the bank...
