Abstract

Recently, the water quality status in northern Alabama has been declining due to urban and agricultural growth. Throughout the years, the application of remote sensing and geographic information system technology has undergone numerous modifications and revisions to enhance their ability to control, reduce, and estimate the origin of non-point source pollution. Yet, there is still a considerable amount of uncertainty surrounding the use of this technology as well as its modifications. This research demonstrates how the application of remote sensing, geographic information system, and global positioning system technologies can be used to assess water quality in the Wheeler Lake watershed. In an effort to construct a GIS based water quality database of the study area for future use, a land use cover of the study area will be derived from LANDSAT Thermatic Mapper (TM) imagery using ERDAS IMAGINE image processing software. A Digital Elevation Model of the Wheeler Lake watershed was also from an Environmental Protection Agency Basins database. Physical and chemical properties of water samples including pH, Total Suspended Solids (TSS), Total Fecal Coliform (TC), Total Nitrogen (TN), Total Phosphorus (TP), Biological Oxygen Demand (BOD), Dissolved Oxygen (DO), and selected metal concentrations were measured.

应用遥感、地理信息系统和全球定位系统技术改善阿拉巴马州北部的水质

最近，由于城市和农业的发展，阿拉巴马州北部的水质状况一直在下降。多年来，遥感和地理信息系统技术的应用经历了多次修改和修订，以增强其控制、减少和估计非点源污染来源的能力。然而，围绕这项技术的使用及其修改仍然存在相当多的不确定性。本研究展示了如何应用遥感、地理信息系统和全球定位系统技术来评估惠勒湖流域的水质。为了构建一个基于GIS的研究区域水质数据库以供未来使用，研究区域的土地利用覆盖将使用ERDAS IMAGINE图像处理软件从LANDSAT热成像仪(TM)图像中获得。惠勒湖流域的数字高程模型也来自环境保护局流域数据库。测定水样的理化性质，包括pH、总悬浮固体(TSS)、总粪便大肠菌群(TC)、总氮(TN)、总磷(TP)、生物需氧量(BOD)、溶解氧(DO)和选定金属浓度。
