The Mediterranean region is an area particularly susceptible to water scarcity and drought. In this work, drought has been analyzed in Italy using multiple timescales of the standardized precipitation index (SPI) evaluated from Integrated Multi-satellitE Retrievals for Global Precipitation Measurement product 2000 2020. particular, characteristics (severity, duration, intensity) have estimated ...

Reduced water reserves can be caused by decreased rainfall. During the dry season along Lusi River, Central Java, quantity decreased, so that area River passes in drought conditions. This study aims to determine longest duration of and largest cumulative number droughts, watershed for a ten-year period. The level was analyzed using Theory Run method. results obtained were 9 months amount -486 m...

The "hydraulic city" of Angkor, the capitol of the Khmer Empire in Cambodia, experienced decades-long drought interspersed with intense monsoons in the fourteenth and fifteenth centuries that, in combination with other factors, contributed to its eventual demise. The climatic evidence comes from a seven-and-a-half century robust hydroclimate reconstruction from tropical southern Vietnamese tree...

This study presents a methodology for the analysis of a drought climatology within a particular region that enables a user to define drought areas at a high spatial resolution. It is suitable for quantifying the relative differences in the intensity of drought spells, and the frequency and duration between individual stations within an area of interest. The methodology is based on the Standardi...

The aim of this study is investigation of climate change impact on Karoon3 basin in future periods. For this purpose, the simulated precipitation and potential evapotranspirationof four AOGCM models was used to simulate drought index. Monthly precipitation was calculated by inverse distance weighted method. Reclamation Drought Index (RDI) was used as watershed drought index. RDI was calculated ...

Understanding the propagation from meteorological to hydrological drought is crucial for monitoring and forecasting. In this study, daily precipitation streamflow data of 16 sub-catchments in Huaihe River Basin 1980 2014 are used establish a framework quantitatively reveal relationship between explore impact climate, catchment properties, human activities on propagation. The divided into three ...

Six water emergencies have occurred since 1981 for the NewYork City (NYC) region despite the following: 1) its perhumid climate, 2) substantial conservation of water since 1979, and 3) meteorological data showing little severe or extreme drought since 1970. This study reconstructs 472 years of moisture availability for the NYC watershed to place these emergencies in long-term hydroclimatic cont...

Elevated atmospheric [CO(2)] (eC(a)) often decreases stomatal conductance, which may delay the start of drought, as well as alleviate the effect of dry soil on plant water use and carbon uptake. We studied the interaction between drought and eC(a) in a whole-tree chamber experiment with Eucalyptus saligna. Trees were grown for 18 months in their C(a) treatments before a 4-month dry-down. Trees ...

Early duration drought tolerant rice culture CB 06803, a derivative of the cross PMK (R ) 3 x Norungan was released as Rice CO 53 during year 2020 an alternate variety for Anna(R)4, with 115 -120 days duration. It possesses desirable features like high yield, tolerance and better physiological efficiency. This semi dwarf stature has efficient tillering capacity, long droopy panicles highly acce...
