Chapter 6 - Assessment of COVID-19 lockdown impact on surface water quality using remote sensing techniques in Raipur, Chhattisgarh, India

Abstract

Due to improper management, industrialization and urbanization resulted in poorer surface and river water quality flowing through the city. Still, complete lockdown in the country resulted in improved surface water quality. Hence, a study has been performed to analyze these changes held during COVID-19 lockdown using a combination of different parameters derived from spatial data. The study includes analyses of significant water bodies, surface water bodies through out the city; the survey has proven that the lockdown situation that occurred due to the pandemic has resulted in improved water quality which has been determined based on water bodies analysis done for 12 major water bodies, and by the study performed it has been observed that the area of the nonturbid water has increased by 0.148 sq. km after the lockdown situation occurred. The study will be helpful to assess the impacts of lockdown on water bodies to take the sustainable measures which can be taken shortly for the improved regulation of pollutants and other contaminants based on positive effects on the surface water quality.
