Regional Drought Assessment Based on the Reconnaissance Drought Index (RDI)
TL;DR: In this article, the Reconnaissance Drought Index (RDI) is proposed together with the well known Standardized Precipitation Index (SPI) and the method of deciles.
Journal ArticleDOI
Towards a drought watch system based on spatial spi
George Tsakiris,Harris Vangelis +1 more
TL;DR: In this paper, a method based on the estimation of SPI over a geographical area and its use for characterising drought is presented, which can be easily applied and can support a Drought Watch System foran area of mesoscale dimensions.
Journal ArticleDOI
DrinC: a software for drought analysis based on drought indices
TL;DR: The paper aims at presenting the overall design and the implementation of the software along with the utilisation of various approaches for drought analysis, as well as providing a module for the estimation of potential evapotranspiration through temperature based methods, useful for the calculation of RDI.
Journal ArticleDOI
The effect of PET method on Reconnaissance Drought Index (RDI) calculation
TL;DR: In this article, the authors compared the results of RDI for various reference periods using some popular empirical PET methods with minimum data requirements, including Hargreaves, Thornthwaite, Blaney-Criddle and FAO Penman-Monteith (only temperature).

TL;DR: In this paper, an innovative system-based approach for drought analysis, which can lead to rational decisions for combating drought, is presented, where concepts of water scarcity (drought, water shortage, aridity and desertification) are viewed within the perspective of new approach.
