This research uses a combined water quality index (WQI) and pollution index (PI) to assess and characterise groundwater quality. Water samples will be collected from nine locations in the study area for the assessment. The water quality index was calculated based on Total Dissolved Substances (TDS), Nitrogen oxides (NOx), Calcium (Ca), Magnesium (Mg), Sodium (Na), Potassium (K), Chloride (Cl), Sulphate (SO4), Bicarbonate (HCO3), Fluoride (F), Power of Hydrogen (pH) and Electrical Conductivity (EC). These twelve parameters were analysed and characterised according to standard methods and the Indian standard, which were then used in calculating the water quality index. Groundwater quality and pollution status of the Adyar river basin were assessed using the Groundwater quality index and comprehensive pollution index for the years 1990, 2005, and 2020. A result reveals t...

The main aim of the paper is to comparatively analysis the air quality index of both the Delhi and Chennai. The objective of the study is to compute the AQI of both the cities and to compare it. For both the cities data for the computation of the AQI are taken from the secondary source from Central Pollution Control Board (CPCB) and Tamil Nadu Control Pollution Board (TNP). It is found that in both the city main source of pollution are from both anthropogenic and natural genesis. The pollutants which make the reading of AQI severe is emitted from the transportation sector such as emission from the vehicles, road side dust particles followed by the pollutants from the industries and construction site. In Delhi sandstorms from the desert regions during the summer season and bursting of firecrackers in diwali are responsible for shooting the AQI during March and November month respectively. D...

The climatic factors connected with Dengue fever happening in Chennai were investigated. The factors accountable for Dengue fever have been recognized and mapped to dengue cases in Chennai city. This work studies the association between yearly climate patterns between 2016 and 2017 and the spread of Dengue fever in Chennai. Monthly rainfall and temperature is taken as the factors of study. The study develops a statistical analysis to quantitatively assess the relationship between climate and Dengue fever. The correlation technique was used to fit the statistical model. The Inverse Distance Weighted (IDW) interpolation and Geographic Information System (GIS) techniques were used in mapping the spatial diffusion of Dengue fever risk zones. The results show that there is a significant correlation between Dengu...

This study examined the spatial distribution of dengue through the hotspot analysis in Royapuram, Chennai city, India, during 2018 -2019. This study result indicated that the number of dengue cases infected higher among males than in female’s population and the more infected age group was between (15-64) adult population and most of the dengue cases were recorded in this age groups it based on this classification age group is more in number of populations. Spatial distribution of dengue cases was significantly identified the dengue hotspot in Royapuram, Chennai. Hotspot analysis of Dengue epidemiological incidences helped in identification the core vulnerability areas of disease risks. The study also analyzed the external environmental variables like rainfall and mosquito menace strongly determine the dengue cases in the year of 2018 – 2019. It was found that there was no positive correlation with of environmental variables...

In the metropolis of Chennai, the first laboratory-confirmed chikungunya cases had an onset of symptoms at the end of May 2006. The authors reviewed surveillance data in which a suspected case of chikungunya was defined as a patient presenting with fever and arthralgia at a medical camp in Chennai on and after June 20, 2006. Over the same period, the authors reviewed surveillance data and larval indices for the vector Aedes aegypti. From June 20 to October 10, 2006, they reported 4,760 suspected cases of chikungunya (attack rate of 0.1%, no fatalities). Control measures included removal of breeding sites, daytime fogging against adult mosquitoes, and information campaigns. The early detection and effective prevention of future outbreaks rely on strengthened human and entomological surveillance, participation of private medical practitioners in case reporting, and community involvement to reduce potential br...

It also tries to identify which image tends to be better for groundwater analysis without ground truth verification. In present going to field and then selecting spot for digging the groundwater is tiring and time taking. The need of conservation and its resource assumes more importance than ever before. Water scarcity has always remained a problem in the city of Chennai. For conserving of water, the study attempts to mark the potential zone which is exposed for getting polluted and contributing to health risk. The various thematic maps have been prepared such as landuse pattern, soil type, geology, geomorphology and lineament were used for identifying the potential zone. Weightage and ranking were given to each parameter before overlaying all the parameters. Therefore, the study is to sort the problem of ground truth verificat...

Without water life as it exists on our planet is impossible (Asthana and Asthana, 2001).97.5% of water on the earth is salt water, leaving only2.5% as fresh water of which over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is mainly found as groundwater, with only a small fraction present above the ground or in the air. Fresh water is a renewable resource, yet the world’s supply of clean, fresh water is steadily decreasing. INTRODUCTION

Erosion calculation requires huge amount of information and data, usually coming from different sources and available in different formats and scales. Therefore GIS technique has been used, which helped considerably in organizing the spatial data representing the effects of each factor affecting soil erosion. The factors that most influence soil erosion are linked to topography, vegetation type, soil properties and land use/cover. Average annual soil losses were calculated by multiplying five factors. A set of factors as identified in the USLE were studied and reviewed. These include rainfall erosivity factor (R-factor), soil erodibility factor (K-factor), slope and slope length factor (LS-factor), and vegetative cover factor (C-factor) and conservation practice factor (P-factor). Each factor which consi...
