Sediment Yield

MAYSVILLE, Kentucky, U.S.A. (January 2019) — Carlson Software’s Nicholas Bugosh, GeoFluv Technical Director, published the evaluation of sediment production from native and fluvial geomorphic-reclamation watersheds at La Plata Mine.

The San Juan Coal Company reclaimed 743 hectares at its La Plata Mine using the GeoFluv fluvial geomorphic reclamation design method from the years 1999 through 2008. The goal was to achieve long-term stability against erosion, reduced maintenance, and increased biodiversity as compared to traditional reclamation methods.

After qualitative inspections, the completed reclamation confirmed the fluvial geomorphic reclamation method benefits. In 2011, The company began to study the sediment production rate from these geomorphic landforms and surrounding undisturbed native lands.

Data was acquired from three different subwatersheds, native, fluvial geomorphic design with topdressing and poorly established vegetation, and fluvial geomorphic design with topdressing and significant vegetation growth. Precipitation, sufficient enough to cause sediment transport, provided data for the end of 2012, all of 2013, and the beginning of 2014. Temporary check-dam-type sediment control structures designed to impound runoff from a two-year, one-hour storm were installed at each subwatershed outlet. Erosion pins in the impounded area facilitated sediment deposition measurement and precipitation was recorded by the La Plata Mine Meteorological Station and supplemental site-specific precipitation gauges.

The site data provided direct relationships between sediment production and precipitation. The fluvial geomorphic design with topdressing and poorly established vegetation site averaged 13% lower sediment yield than the native site and the fluvial geomorphic design with topdressing and significant vegetation averaged 41% lower sediment yield than the native site. Land-disturbing activities that can accelerate erosion and sediment yield will accompany global population growth. The results of the study indicate that use of the GeoFluv method can mitigate erosion and sediment yield increases associated with that growth.
