MAP Rain – Helping to monitor and predict flooding events

MAP Rain is our high performance, flexible and scalable cloud-based solution for rainfall and flood monitoring analytics.  MAP Rain delivers location specific rainfall analytics for any point and any area of interest.

Flood Investigation

We’re currently working with our new clients Hertfordshire County Council and East Sussex County Council to calculate what their high limit properties should be set to at each of their Point and Catchment locations using their historic flood events. They have sent us a list with all their flood incidents that have occurred over the past 3 years. Each incident had a date, time and x and y coordinates associated to them. We then imported all that data into a programe called ‘R’ (‘R’ is an open source programming language and software environment for statistical computing and graphics that is supported by the ‘R’ Foundation for Statistical Computing. The ‘R’ language is widely used among statisticians and data miners for developing statistical software and data analysis). Using ‘R’ we were able to transform each x, y coordinate into a unique RESTful API link. This allowed us to automate the process of getting the results for each of the flood events directly from MAP Rain into the ‘R’ programe. The results we pulled from MAP Rain for each flood event  was as follows:
  • API 30 – API 30 is used to calculate how saturated a particular area is based on the past 30 days of rainfall and soil types.
  • Return Period – For this we are use the Bilham method (we will be writing an article on the relationship between the FEH99 and Bilham methodology)
  • Rainfall intensity – This is calculated in mm/hr
We will be using this information to find a relationship between each property and the Flood Event alarms so that we can accurately send out alerts based on current and forecasted radar rainfall data.
