Sentences with phrase «hydrological drought»
Hydrological drought refers to a period of time when there is a shortage of water in a specific area, such as a river, lake, or groundwater, affecting its overall availability for human and ecosystem needs. It occurs when the amount of water available drops below normal levels, leading to a drought-like situation. Full definition
The researchers from Wageningen University & Research, Bogor Agricultural University in Indonesia, University of East Anglia and the Center for International Forestry Research analysed the spatially distributed pattern of hydrological drought, that is the drought in groundwater recharge, in Borneo using a simple transient water balance model driven by monthly climate data from the period 1901 - 2015.

This study highlights the importance of considering hydrological drought for wildfire prediction, and the researchers recommend that hydrology should be considered in future studies of the impact of projected ENSO strength, including effects on tropical ecosystems, and biodiversity conservation.
The team also explored the link between hydrological drought and wildfire using the monthly fire area burnt from the spatially distributed Global Fire Emission Dataset from the period 1996 - 2015.
We can also think about hydrological drought, or how decreased precipitation affects streamflow, soil moisture, reservoir and lake levels, and groundwater recharge.
Assuming no change to current water resources management, chronic hydrological drought is increasingly possible by the end of the 21st century.
Yusuke Satoh, of the International Institute for Applied Systems Analysis, warned that under the notorious business - as - usual scenario − where nations ignore such warnings and just go on burning fossil fuels − 13 of 26 global regions would see «unprecedented hydrological drought levels» by 2050.
In addition, precipitation deficit or human activities (such as groundwater extraction) can cause water supplies from rivers, lakes, or groundwater to become low, known as a «hydrological drought.»
For example, hydrological drought is closely related to human activities, such as irrigation, thus accurate prediction necessitates the modeling of human activities.
This poses a challenge to the prediction of meteorological drought, as well as agricultural and hydrological drought.
Hydrological drought is based on both precipitation and temperature, which affect the amount of soil moisture.
Now researchers from the US have found that, while meteorological drought — based on precipitation — is projected to become more frequent in areas such as the southwestern states and less so in other regions, hydrological drought is projected to increase across most of the country.
