Water, Land, and Forest Susceptibility and Sustainability: Geospatial Approaches and Modeling, Volume 1 - Chapter 6 - Polluted water bodies remediation by using GIS and remote sensing approach: a deeper insight

Water is among the utmost necessities for living being survival almost from the evolution time of life. Currently, the consumption level of water is highly increased, while the pace of water pollution has also increased. Thus, an urgent requirement for managing and controlling the quality of water is required. And, due to the advancements in the GIS and remote sensing field, it has become possible and easy to perform extensive water remediation study. With the help of geospatial modeling systems and upgraded spatial and spectral resolution sensors, monitoring various factors related to the quality of the water, i.e., turbidity, chlorophyll-a, suspended residues, and algal blooms in different water bodies are even possible at a low price with higher accuracy. In this chapter, a detailed review on the role of GIS and remote sensing for monitoring the quality of water and management and water body remediation is discussed.
