1. If you have a house or property to be constructed or already constructed as per government norms each building should be provided with a rainwater harvesting structure. To determine the capacity of the well or harvesting structure, we need to know maximum rainfall of the area which could be extracted from the chart in millimetres and simply multiply with your area of building (in sq meters or sq feet) which will give you the maximum volume which can be stored.
2. In rural and agricultural fields if we need to construct farm ponds we need to know maximum rainfall which could be extracted from the chart and multiply the rainfall value with your area of your farm that drains into the pond to determine the farm pond capacity.
3. A village head or a water shed manager could do water budgeting by knowing the average or daily rainfall pattern for each seasons.

At Present, the Students or Researchers find it difficult to move out to the field for collecting the information for their study or project-related works. To benefit the students and farming community people I have developed an online web application to get daily rainfall information for any location within Tamilnadu state boundaries. This information can be downloaded as a CSV or PNG extension file which can be used for further analysis. 

The Climate Hazards Group Infrared Precipitation with Station data (CHIRPS) is used as a base data which is having a resolution of 0.05 degrees (5.5 km approx). In the application, one has to search the place of interest in the search tab or simply zoom to the exact location and click on the map to generate the chart with daily rainfall data from (01st January 2009 to 31st December 2019), once the chart is generated by placing the cursor on the graph one can find out the rainfall in millimeters with the date. The Data is however verified with the rainfall station, the accuracy of the data is more than 75 -80%. 

From this chart, one can understand the pattern of rainfall of a location during field visits, to design the rainwater harvesting structure for urban areas and rural agriculture fields. 

Here, is the link

I would like to make a request to forward the link to any users who are working in the water resources field, NGO’s and research institutes. If any suggestions or remarks on the content please let me know.
