An Approach to Determine Land Use Factors to Study Their Influence on Stream Water Quality

EasyChair Preprint 7239

Abstract

Stream water quality is gaining major attention due to increasing population and anthropogenic sources of pollution. These accelerate water quality stress conditions in developing countries especially, like India. Streams are one of the major water resources, and their quality impacts the watershed. They are also influenced by the surrounding land use and land cover (LULC) within the watershed. In this study, we attempted to find out the major land use factors of Godavari river basin. The information of water quality monitoring stations was obtained from the Telangana State Pollution Control Board (TSPCB) website and were delineated using QGIS software. The GlobeLand30 open source classified dataset developed by China compiling the Landsat and Chinese HJ-1 satellite data was utilized in the current study. The urban, forest, agriculture, grassland and shrub land were the major land cover classes considered in this study. First, QGIS software was used to delineate the upper portion or catchment area of sample stations individually. The land use factors for each class were calculated using the arcsine square root of respective LULC areas to their corresponding basin areas. Furthermore, these land use factors are combined with meteorological parameters as inputs to the model for water quality prediction and analysis.

Keyphrases: Godavari river basin, Land use/land cover, Water Quality Parameters, Watershed Delineation
