Simulation of surface mine hydrology with the finite element storm hydrograph model
Use of a spatially responsive finite element model is demonstrated for simulating the hydrologic response of a reclaimed mountaintop removal operation near Beckley, West Virginia. The use of the Finite Element Storm Hydrograph Model (FESHM), developed at Virginia Tech, provides a means of incorporating spatially distributed characteristics of the watershed, thus preserving the natural configuration of overland and channel flow. The research consisted of a series of calibration studies using runoff plot data to estimate values for model parameters and reclaimed mine surface. The model verification consisted of a comparison of simulated and observed runoff characteristics using an ungaged concept. The model was found to predict runoff volume with acceptable accuracy. Peak runoff rate was generally under predicted. Poor performance of the model was noted for long duration, low intensity storm events. Use of the model to evaluate the effect of cover management for modification of hydrologic response was demonstrated.
