A GIS-Based Water Quality Assessment and Pollution Control Planning Approach for Lake Management (WQAPCP)

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