KBDIS

The Keetch-Byram Drought Index refers to a risk assessment often used by meteorologist and local authority to determine if there is a moisture deficiency in a given area. The index is designed to calculate the cumulative moisture deficiency in both the upper and deep soil layer, so it can exhibit an effect that is occurring over the year and not isolated, perhaps due to various local variables.

KBDIS is a tool designed to help you calculate the drought index based on the data you registered on a daily basis. It is worth mentioning that the application works with Excel spreadsheets only, so you need to convert the records to XLS or XLSX before using the tool.

Functionality-wise, the utility is fairly simply to use, meaning that once you load the spreadsheet, you can select the sheet that includes the rainfall records as they are registered on a daily basis by the local meteorology stations.

The actual measurements as made in the KBDI Calculator tab where you can specify the desired years, frequencies and unit of measurement preferred. Take note that the information can be displayed in a graph that can be saved separately by hitting the Plot2Pic button on the top of the UI.
