      Russian River (Sonoma County, 1992) Among the best known examples of channel incision resulting from instream gravel extraction is the Russian River near Healdsburg, where extensive wet pit mining in the active channel in the 1950s and 1960s caused channel incision in excess of 3 m over an 11 km length of river, with a maximum incision of 6 m

  • The impact of gravel extraction on groundwater

      The impact of gravel excavation on a groundwater dependent ecosystem (GDE) in a glacial outwash plain was determined using a combination of timeseries stable isotopic measurements (δ2H and δ18O) and a numerical flow model of lake–groundwater interaction Isotopic analyses of the lake and groundwater indicated a shift from a dominance of evaporative enrichment to more meteoric

  • Impact of floodplain gravel mining on landforms and

      Understanding gravel mining, a very common but aggressive activity, as a morphogenetic action is fundamental for analyzing and assessing the impact on floodplain morphology and the dynamic of riverbeds, on sediments budget and water balance assessment, but also for floodplain planning and resources management Field observations and GIS analysis were performed in a gravel pit area from
