dc.description.abstract |
The problem of soil erosion and sediment runoff in the Indian Run watershed
(area 11, 277 acres), a major tributary to Mill Creek, is of serious concern to the Mill
Creek Metroparks management and the Youngstown metropolitan area community. Mill
Creek is primarily responsible for sediment deposition in Lake Newport that continues at
an alarming rate. A nonpoint source simulation was performed for the Indian Run
watershed using the Agricultural Nonpoint Source Pollution Model (AGNPS) water
quality model with a focus on the problems of soil erosion and sediment yield. Four
hypothetical storm conditions were simulated: (i) 3 in. precipitation of 6 hour duration,
(ii) 2 in. precipitation of 4 hour duration, (iii) I in. precipitation of 1 hour duration, and
(iv) 1 in. precipitation of 12 hour duration. Sensitivity of the results to changes in P, C,
and K factors in the Universal Soil Loss Equation was evaluated. Using the model
results, the mean flow, erosion and sediment yield for the watershed outlet on a yearly
basis were estimated to be on the order of 0.944 cfs/sq. miles, 13.4 tons/acre, and 1100
tons, respectively, which compare favorably with the field measurements. The AGNPS
simulation identifies five cells (each 179 acres in area) that are primarily responsible for
the problems of soil erosion, and sediment deposition in the entire Indian Run watershed.
The sediment deposition and the flow rate predictions are within 10% of measurements
reported [MBR-HER, 1994]. The AGNPS simulation of the watershed provides
information that could be of considerable help in formulating management decisions to
address the problem of sediment deposition in Lake Newport. |
