How to calculate Water Quality Index considering the source type,intended use and climate ?

This WQI's primary innovation is that it calculates the WQI based on the type of source from which water is collected, the WQI's intended use, and the local climate at the time the samples were retrieved. The source or location from where the sample is collected has an impact on the quality of water which the index must incorporate at the time of calculation. The purpose for which the water quality index is calculated changes the weightage of the importance of the different quality parameters. For example, if WQI is calculated for knowing how drinkable the sample is then the weightage of coliform will increase compared to other parameters as the presence of coliform in the drinking water can not be permitted. The climate of the area from where the water is collected is another criterion to consider at the time of calculating the WQI. Based on the climate also the weightage of water quality parameters will vary. There will be a difference in the weight of importance if the sampl...

Five Most Extreme Hydrologic Events that changed the World

Typhoon Tip, Philipines(Collected from : CSMonitor ) Devastating storms, severe flood, acute famine conditions, etc. hydrological events of extreme nature has changed human history. Any event which is not normal is known as an abnormal event. In the case of hydrology, an event that has a return period of more than 100 years is considered Extreme. According to Herring(2020) of Climate.gov, "An extreme event is a time and place in which weather, climate, or environmental conditions—such as temperature, precipitation, drought, or flooding—rank above a threshold value near the upper or lower ends of the range of historical measurements." Though the threshold is not objective, few researchers have defined "extreme events as those that occur in the highest or lowest 5% or 10% of historical measurements". Some have described events by their deviation from the mean, or by their occurrence interval. Here the most severe five extreme hydrologic events were discussed which ...

StartUp that replace SCADA Systems in Water Treatment Plants

Startups play a crucial role in addressing these challenges by introducing innovative technologies and solutions for efficient water resource management, ultimately contributing to the sustainability of our planet. and promoting a cleaner environment for future generations. These new businesses can identify gaps in the current water management systems and develop creative solutions to improve access to clean water sources and combat water pollution. By harnessing the power of technology and entrepreneurship, StartUps can make significant strides in preserving our water resources and ensuring a more sustainable future for all. Through their dedication and innovation, StartUps are paving the way for a cleaner and healthier environment for generations to come. This Podcast as shared above introduced a StartUp that has replaced SCADA-based systems for Real-Time Water Quality Monitoring in Water Treatment Plants in Tamilnadu, India.
