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...

A Hillstation in the North East India facing acute water scarcity

Jampui is a hill station that has recently gained popularity due to its pristine environment, cloud mist in the morning, and peaceful atmosphere. However, it is also experiencing acute water scarcity. Jampui is located in the princely state of Tripura which is one of the seven sisters of North East India. Jampui Hills is a popular hill station in Tripura's North Tripura district. It is about 200 kilometers from Agartala and is the state's highest hill range. The hill range's average elevation is about 3,000 feet above sea level, which gives the hills their distinct weather and gives rise to the name Jampui, which means "Eternal Hills of Spring." The panoramic views from Jampui Hills encompass the Chittagong Hills, the Kanchanpur-Dasda Valley, and the hill ranges of Tripura and Mizoram. Buses connect Jampui Hills to the major cities of North East India. The nearest rail station is Kumarghat/Pencharthal Railway Station, which is approximately 90 kilometers from Vang...

Five open source free hydrologic models that you can use to model runoff of micro to macro watersheds

The principal objective of hydrologic models is to forecast the runoff of a surface water body, especially dendritic systems like rivers, streams, etc. The inputs to these models are generally Rainfall/Precipitation, Soil Characteristics, and other Climatic parameters like evapotranspiration, humidity, etc. LULC and geo-morphology are also used as the required input parameters of the hydrologic models. Both input and output of these models are temporally as well as spatially variable. Now the resolution varies with different models. Some models consider all the sub-basins to be a single watershed and determine the output based on the characteristics of this single watershed(lumped).In contrast, some other models will consider the {impact|effect} of each of the sub-basins on the central outflow of the watershed(distributed).In a few models, the entire watershed is divided into grids or units of uniform dimension. However, the accuracy is highest for the models, which considers the {impa...
