The objective of this study was "to demonstrate the effectiveness of a vegetative filter zone in trapping fine-grained sediments from surface mining operations." The area selected for study was located in Whitley County, Kentucky, directly below an active surface mining operation. The out-slope above the filter was the primary drainage area monitored during this study. This project was initiated for the specific purpose of conducting a field test on vegetation as a viable sediment trapping medium. From the onset, the project was wholly designed for a field evaluation under typical mining conditions. The filter area was constructed directly below an abandoned surface mine bench, on typical soil types found in mined areas of Eastern Kentucky. The outslope located above the filter was the primary area, from which sediment-laden drainage was to be diverted to the inlet monitoring station. Sediment-laden water samples were collected at the inlet flume for comparison with samples collected at the outlet flume to permit evaluation of the sediment removal capability of the vegetative filter. Results of the monitoring effects revealed that a dramatic reduction in sediment load was achieved by vegetative filtration for particle sizes larger than clay. Based on the results of this study, it was concluded that vegetative filters are an effective control for reducing the quantity of sediment transported into surface streams and rivers from disturbed mined lands. |
