This chapter aims to present two case studies, which could be the example of the linkage between climatological and hydrological approach in drought assessment on an operational level. The first case study describes the operational meteorological drought monitoring, which has run since 2015. The ...
An event would be considered an exceptional drought if the absolute value of deficit exceeds − 93.93 km3 in January. For the Markazi basin, due to its arid climate, the absolute value of drought threshold is less than the Ganges–Brahmaputra basin. For example, in January, an abnormally...
For example, for the shallow soil, there were cases where three simulated soil moisture minima were contained within one long drought event identified by the index, while in other cases the simulated event was too short to be recognised by the more dampened response of the index. Results show...
Like many other African countries, incidence of drought is increasing in Nigeria. In this work, spatiotemporal changes in droughts under different representative concentration pathway (RCP) scenarios were assessed; considering their greatest impacts on l
drought. For example, the methodology here needs to be geared towards eventually explaining Figs. 2 & 3, in which the metric is spatial coverage in the median trends (upward, downward and insignificant) in the severity of extreme drought events (10-yr and 100-yr return periods), based on ...
For example, Fu et al. (2018) used standardized precipitation index (SPI) to analyze the characteristics of meteorological drought in Northeast China. Veettil and Mishra (2020) analyzed the relationship between hydrological drought and climate, watershed, and other factors by using standardized runoff...
Current and potential drought conditions, based on the Standardized Precipitation Index (SPI) and forecasted evapotranspiration; The likelihood that irrigation will be needed. “Combining our weather forecasts with crop growing cycles enables farmers dealing with the effects of global warming to make optim...
Drought is among the costliest natural disasters that affect the economy, food and water security, and socioeconomic well-being of about 1.4 billion people in India. Despite the profound implications of droughts, the propagation of meteorological to hydrological droughts in India is not examined. Her...
3.2.1Analysis of drought and waterlogging Relevant research has reported that spring drought, early summer drought and corresponding waterlogging are the primarymeteorological disastersoccurring during the crop growing period in the study area, and of these, spring drought occurs much more frequently than...
For example, extensive hydrological models that replicate hydrological processes to produce data on soil moisture or runoff have effectively been applied to investigate the characteristics and varieties of drought propagation, especially during the shift from MD to soil moisture drought or HD (Apurv and...
