Book Spatial and Temporal Changes of Water Quality of the White River Over Two Decades and Suitability for Irrigation

Download or read book Spatial and Temporal Changes of Water Quality of the White River Over Two Decades and Suitability for Irrigation written by Md. Shahin Alam and published by . This book was released on 2020 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water quality degradation has been a significant concern in the White River watershed of Indiana. As a consequence of long-term inputs of industrial and domestic effluents, and urban and agricultural runoff, the White River has been adversely affected. Some major on-going concerns include excess nutrients, organic compounds, and salinity. Water quality degradation effects extend beyond the local scale, as the White River is a headwater stream and drains into the Mississippi River. Water quality issues become more complex with changing climate, which shifts streamflow regime and water quality. One emerging water quality concern regarding climate change is irrigation suitability of water under the potential shift from rain-fed agriculture to irrigation agriculture in the Midwest. To address these issues, this thesis research: 1) analyzed the long-term secondary water quality data using a novel approach, Weighted Regression on Time, Discharge and Seasons; and 2) collected bi-weekly water samples from the White River during the crop growing season of 2019, and comprehensively analyzed the irrigation suitability of the water. Long-term water quality data analysis of five monitoring sites show that overall flow-normalized concentration and flux of biochemical oxygen demand (BOD) and nitrate-nitrite nitrogen increased from 2002 to 2018. The only exception occurred at the Walnut monitoring site where both nitratenitrite nitrogen concentration and flux decreased. Analysis of pollutant sources indicates that point source pollution and combined sewage outflows may have a substantial contribution to nutrient pollution, and agricultural and urban runoff has a big impact on the both the nutrient and BOD load in the river. Irrigation suitability analysis concludes that the water is mostly suitable for irrigation; however, suitability exhibits distinct patterns between May–July and August–October. An average of 7.8% of samples from May-July are unsuitable for irrigation, while an average of 24.5% of samples from August-October are unsuitable for irrigation. Considering that AugustOctober is the dry and low-flow season when water demand is high, the results suggest a notable possibility that water is unsuitable for irrigation when most needed. This is the first comprehensive study to evaluate irrigation suitability of surface water in the Midwest United States. Meanwhile, the long-term water quality analysis and identification of pollution sources are critical for understanding the driver of water quality in the context of climate and streamflow changes. The results of this study will inform water resources managers responsible for formulating future conservation plans

Available in PDF, EPUB and Kindle. Book excerpt: Addressing ecologists, legislators, lawyers, and industrialists alike, Ruth Patrick asks what has been accomplished with the millions of dollars spent on upgrading our surface waters. Has the water improved in spite of the fact that the crayfish, snails, and algae are not those that one would expect to find in natural rivers and estuaries? To evaluate the success of environmental laws over the past two decades, the author examines the aquatic life of river systems in the Delaware Valley, Texas, and Georgia--the only areas in the United States where she found enough biological data to determine trends over time. Although tracing the impact of environmental laws is difficult, Patrick found that for these three water systems the results were generally positive. However, if society as a whole wants effective environmental legislation, organizations must take on a more systematic and orderly approach to data gathering. Patrick argues that in monitoring the waters, one must study protozoa, algae, and worms as well as fish, oysters, and shrimp; one must track amounts of metal as well as low concentrations of oxygen. In proposing options for the future, the author predicts that the cost of such monitoring will be higher than present expenditures, but the cost of lax control will be even greater.

Book Water Supply and Water Scarcity

Download or read book Water Supply and Water Scarcity written by Vasileios A. Tzanakakis and published by MDPI. This book was released on 2020-11-04 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Book includes selected papers that has been published in the Water journal Special Issue (SI) on Water Supply and Water Scarcity. Moreover, an overview of the SI is included. The papers selected for publication in the SI include review and research papers on water history, on water management issues under water scarcity regimes, on rainwater harvesting, on water quality and degradation, and on climatic variability impacts on water resources. Overall, the issue identify and highlight the main challenges in water sector, and particularly in management and protection of water resources and in use of alternative (non-conventional) water resources, especially in areas with demographic change and climate vulnerability in order to achieve sustainable and secure water supply. Furthermore, general guidelines and possible solutions for an improved and sophisticated water management system are proposed and discussed, such as the adoption of advanced technological solutions and practices that improve water-use efficiency and the use of alternative water resources, to address the growing environmental and health issues and to reduce the emerging conflicts among water users.

Book An Analysis of Spatiotemporal Variations of Water Quality in the Little River Watershed and Their Connection with Land cover Patterns

Download or read book An Analysis of Spatiotemporal Variations of Water Quality in the Little River Watershed and Their Connection with Land cover Patterns written by and published by . This book was released on 2008 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Little River supplies drinking water to Blount County, Tennessee, and supports several state and federally listed species. The upper, southeastern area of the Little River watershed is fed by protected sources originating in the Great Smoky Mountains National Park. In the lower, northwestern part, however, the watershed has been affected by anthropogenic land-cover and land-cover change in recent years. These changes may have impacted water quality in the Little River watershed over the past 20 years. The objectives of this study were: (1) to elucidate the spatiotemporal patterns of water quality, (2) to understand the Little River watershed's land-cover patterns, and (3) to quantify the relationships between land-cover patterns and water quality. Existing water quality data for the past 20 years from different sources were compiled and analyzed using multivariate statistical analysis. Principal component analysis (PCA) was used to identify the associations among water quality parameters. Cluster analysis (CA) was used to group sampling sites with respect to water quality pattern. Discriminant analysis (DA) was used to identify which water quality indicators best represent the differences between the clusters derived from CA. Land-cover data were analyzed to determine types and proportions of different land-cover types upstream from water quality sampling sites. The results of the analyses were visualized using Geographic Information Systems (GIS). The results show that specific conductance, turbidity, and ammonia nitrogen best reflect the processes influencing data set variability (dissolved solids, seasonal influences, and nutrients, respectively). The results also suggest that water quality differs between samples from the upper and lower parts of the watershed and that the four parameters dissolved oxygen, total phosphorus, ammonia nitrogen, and total suspended solids define spatial groups of sample sites with similar water qualities. There is a spatial relationship between patterns of land cover and patterns of water quality. Higher proportions of anthropogenic land cover (e.g., urban) occur within the same sub-watershed as degraded water quality measures. The results suggest that anthropogenic land cover influences spatial variations of water quality in the Little River.
