This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Limited biological recovery in acid mine drainage (AMD) impacted streams may be due in part to a flushing response caused by rainfall events. While there is very little water required to react with sulfide minerals to form AMD, more is required to dissolve and transport the chemical products. Increased discharge allows for the transport of accumulated reaction products from mineral surfaces and mobilization of sediments from streambeds. The objective of this study was to investigate this flushing behavior in the heavily AMD impaired Hewett Fork Watershed by tracking the changes in water chemistry over the course of multiple rain events and seasonal flow regimes.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Although acid mine drainage (AMD) in the Appalachian Coal Basin has been studied for decades, the effects of climate change on these streams are not well documented. Climate change predictions for this area include increased storm frequency and intensity, which may alter AMD generation, iron hydroxide precipitation, and fate and transport of contaminants and sediments. These processes substantially affect nutrient availability and the biological communities inhabiting these streams. This study investigates the potential effects of climate change on a treated AMD stream, Hewett Fork, by quantifying changes in nutrient concentrations, sediment transport, and algal biofilm biomass during normal and storm conditions.

Available in PDF, EPUB and Kindle. Book excerpt: In southeast Ohio, Raccoon Creek Watershed (RC) has an extensive mining history resulting in acid mine drainage (AMD) and subsequent environmental problems. Modeling of the discharge and chemistry, as well as an assessment of the impact of climate change in discharge and chemistry of AMD, impacted Hewett Fork, a tributary of Raccoon Creek, is the focus of this thesis. Discharge measurements are collected by the United States Geological Survey (USGS) gage station at the Bolin Mills (BM) station on the main stem of Raccoon Creek. This data for the period 2011-2019 has been analyzed to develop a prediction model for BM discharge, in addition to assessing the impact of climate change on BM flow event under two climate scenario (RCP4.5 and RCP 8.5) and subsequently use the model to predict flow and water chemistry in Hewett Fork. Precipitation, antecedent precipitation index (API), and air temperature were the input variables considered in this study for transient data analysis using the program PAST, and additional variable such as antecedent temperature index (ATI), and potential evapotranspiration (ET) for modeling studies using Artificial Neural Networks (program NeuroShell2). The result of the transient data analysis highlighted the quick flow, baseflow of the watershed, delay time, and total response time. The immediate response time (zero-day lag) of BM discharge following API, in addition to its strong spectrum signal (0.22Hz), indicates a strong influence of API on BM discharge. The Neural Network Model using group method of data handling (GMDH) and generalized regression neural network (GRNN) shows a variation of prediction models for BM due to parameters such as decay factor in API and ATI, as well as in the evapotranspiration input variables of the model. However, the study reveals that the GRNN model for BM is the most suitable for BM prediction based on its performance, with an r-value greater than 0.90, and its ease in predicting discharge by specifying a data set to be added to the data set for training and calibrating the network. The result of the water chemistry model using GMDH, with r values greater than 0.80 for each model, shows the input variables have a good capacity to predict chemical concentration/load in the HF stream. Five climate model projections for the future periods 2020-2039, 2040-2059, 2060-2079, and 2080-2099 were analyzed in this study to simulate three flow events(high, low, and intermediate flow) in BM. The flows simulated by the GRNN model in response to the future climate model projections showed a consistent increase in low flow and high flow and a decrease in intermediate flow for all future time intervals.t
