We present a method and system to visualize water pollution levels of a water model. The user can select a location and time of interest and the system will present its result regardless of whether water data was present for it. If the data was present, it will be presented. Otherwise, data from neighboring locations and time-periods will be used analytically along with river models to estimate the pollutions result for the place and time of interest.

System and Method for Water -body Pollution State Visualization

Pollutions agencies around the world are tasked to measure 10s and 100s of parameters for organic, chemical, radiological and other pollutants based on different standard. The required water quality is strictly connected with its use and hence the water end user, in terms of various standards, defines the appropriate conditions. Different uses are drinking water , municipal sewage treatment, industry supply, agriculture, fish culture, water transport and navigation, energy production, recreation etc.

A system that displays water body pollution states in real-time is therefore a very critical component in water users decision making. However, there is no way to show state of pollution of water bodies. Typically, the water quality data collected remotely by sensors installed in water bodies and readings are transmitted via satellite. Mostly current conditions are displayed on a map, table, or as a time series graph for a particular location. There is essentially no provision to show water body pollution state in between the un-supervised locations. Also the permissible values of water quality indicators vary with country and end-use. Therefore this disclosure

presents a system that provides following

    Convey the pollution state of a water-body at supervised as well as unsupervised locations, e.g., pollution level along the river stream

    Convey the pollution state for a purpose, e.g., agriculture, sewage treatment, drinking

This system has several benefits for the end-user as it can serve the various purposes like

    Simplifies results for user into easy-to-understand states for both technical and non-technical decision makers

    Shows a summary of state according to the underlying purpose
Shows information of the pollution sources leading to the deviations from the mean state

    Has High Granularity as the variations along the river/tributary streams are captured

Failure resistant even if some sensors become in-operational

Details of the solution

We propose a system as outlined in the following flowchart

Following is the step-wise flow of the solution

Step 1: Given the desired location/ area on a chosen river, an area enclosing the location and river is first identified. For example, if the chosen river is Yamuna and Location in New Delhi,

portion of Yamuna in the city of New Delhi along with the city boundary will be displayed.

Step 2: In order to compute the state of the chosen river stretch, the river stretch is segmented based on sensor locations and the geographical boundaries in the "Rive...
