This book was released on 2017 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many lakes are receiving large volumes of contaminants from agricultural discharges, industrial emissions and municipal wastewater, which causes significant surface water pollution. The adverse environmental and health effects of lake contamination are a primary concern in environmental management. Water quality assessment methods and pollution control planning models are useful tools for researchers and decision-makers to protect ecological environments and develop local economies. Also spatial information technologies such as Geographic Information Systems (GIS) make it possible to manage water bodies with more detailed location-based information. The goal of this thesis is to develop a GIS-based water quality assessment and pollution control planning approach for lake management (WQAPCP), which includes the following components: (1) evaluation of water quality based on four index methods with inter-comparisons; (2) pollution control planning for a lake system based on an integration of pollutant distribution simulation and optimization models along with water quality index measures; (3) GIS technology to help implementing water quality assessment and lake contamination control optimization by creating displayed maps of the study results to provide spatial support for decisions.Several water quality evaluation methods are first presented in this thesis within the GIS framework to examine water quality index models, including the US Oregon water quality index (OWQI), the Canadian water quality index (CWQI), the Chinese single-factor water quality index (CNWQI-S) and the Chinese comprehensive water quality index (CNWQI-C) methods. These index methods are applied to assess the water quality of a real case. The assessment results are presented in the form of GIS maps containing the spatial distribution of the water quality levels and their ranking. Through an example of sensitivity analysis and comparison of four sets of water quality assessment results, the parameters with the most significant influence on lake water quality are identified and the most suitable method of water quality evaluation is put forward to support future lake management.Subsequently, this thesis develops a simulation-optimization approach by integrating lake water quality simulation and lake pollution control optimization. A contaminant dispersion simulation is first conducted to provide input for the optimization study. Particularly, a single-objective programming (SOP) model and a multi-objective programming (MOP) model are developed, applied, and compared to support effective lake water contamination control planning under different lake management scenarios. Three periods and a set of significant levels are considered in the real case study to provide a comprehensive dynamic modeling and optimization analysis of lake pollution control through the simulation-optimization approach. Based on the developed optimization method and the case study results, the OWQI and CNWQI-C methods are utilized to help formulating the effective measures for lake water quality management. GIS technology is employed in this study to link the water quality assessment approaches and the lake pollution control optimization. By integrating the relevant data and creating visualized maps of the study results, GIS plays an important role in extending the modeling and assessment results for the lake water quality management with spatial geo-references.

This book was released on 2020 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research explores the use of Sentinel-2 satellite to determine the spatiotemporal patterns of lake water quality indicators (e.g. chlorophyll a) in Lake Bloomington and Evergreen Lake. Lake water quality issues related to algal blooms is a serious problem in basins with abundant agricultural lands causing harmful effects to freshwater ecosystems such as pollution of beaches, taste and odor problems in drinking water, depletion of oxygen levels causing fish kills and the issue of water exceeding safe drinking water standards. Developing monitoring techniques using various water quality indicators of algal blooms is crucial. In this project, remote sensing and field sampling methods were employed to assess the state of water quality of two small lakes, Lake Bloomington and Evergreen Lake, in Central Illinois. Water samples were collected from selected locations from the lakes to test for various water quality variables including nitrate, phosphorus and chlorophyll a. An exo sonde instrument and secchi disk was used to measure additional water quality parameters such as turbidity, secchi depth, and temperature. Concurrent satellite images obtained from Sentinel-2 with flyover with ℗ł5 days were processed and analyzed, and the results were compared with field sampling data. Single and multiple pixel analyses were conducted on various algorithms such as Bottom-of-Atmosphere (BOA), Maximum Chlorophyll Index (MCI), and band ratios. These algorithms were tested to identify the best algorithm for estimating water quality parameters using satellite data for the two lakes. A regression analysis was conducted to derive a linear model which was used to create water quality indicator maps that showed the spatial pattern of algae in the lakes. From the results of the research, Lake Bloomington was more turbid and had higher concentrations of chlorophyll a than Evergreen Lake. Except for band ratio of B1/B2 of Sentinel-2 data, a poor regression relationship between satellite and field water quality values was observed for Lake Bloomington. This poor relationship could be due to the high turbidity of the lake. Evergreen Lake, on the other hand, showed a stronger relationship between satellite values and chlorophyll a. Generally, spatial analysis reveals that chlorophyll a distribution was heterogeneous, and it increased from downstream areas to upstream areas.
