DrinC (Drought indices Calculator) software aims at providing a user-friendly interface for assessing drought indices, suitable for meteorological, hydrological and agricultural drought analysis. The following drought indices are currently included in DrinC:
– Standardised Precipitation Index (SPI)
– Reconnaissance Drought Index (RDI)
– Streamflow Drought Index (SDI)
– Agricultural Standardised Precipitation Index (aSPI)
– Effective Reconnaissance Drought Index (eRDI)
– Precipitation Deciles (PD)
The assessment of the above indices requires commonly available data, while their outcomes can be easily interpreted and used in strategic planning and operational applications.
The calculation process is performed through a graphical user interface and the available options can be adjusted for fitting drought analysis objectives of any particular case. Furthermore, DrinC includes additional tools, such as the estimation of potential evapotranspiration (PET) through temperature-based methods (Hargreaves, Thornthwaite, Blaney-Criddle) and the assessment of the aridity index (AI) for characterising the climate of the study area.
DrinC software is provided for free and it is available at the download page, along with other useful resources. Before downloading the software, you will also have the option to register.
