Wetland mitigation functions on hydrological droughts: From drought characteristics to propagation of meteorological droughts to hydrological droughts

Journal of Hydrology, 2023
Wetlands have been singled out as a potential nature-based solution for improving the resilience and reducing the risks of hydrometeorological extremes. However, whether and to what extent wetlands can affect hydrological droughts is not well understood.

HYDROLOGICAL DROUGHT AND FIRE RELATIONSHIP

Proceedings of the XXVII Conference of the Danubian Countries on Hydrological Forecasting and Hydrological Bases of Water Management, 2020
Drought can be defined in meteorological terms or in relative terms with respect to hydrology and ecosystems. Meteorological drought is not a necessary or a sufficient condition for fire, because fires burn during conditions of normal seasonal aridity. Drought occurs without wildfires in the absence of ignitions.

Comparison of Meteorological Drought and Hydrological Drought Index

Journal of the Korean Water Resources Association, 2015
본 연구는 기상학적 가뭄지수가 수문학적 가뭄에 대한 모사정도를 검토하였다. 기상학적 가뭄지수 중에서 강수량을 변수로 하는 SPI(Standardized Precipitation Index)와 강수량 및 증발산량을 변수로 하는 SPEI(Standardized Precipitation Evapotranspiration Index)를 이용하였고, 수문학적 가뭄 평가를 위하여 월 총 유입량과 하천수 가뭄지수인 SDI(Streamflow Drought Index)를 계산하여, 최종적으로 기상학적 가뭄지수와 수문학적 가뭄지수와의 상관정도를 분석하였다.

Probabilistic characterization of hydrological droughts

Russian Meteorology and Hydrology, 2013
It is proposed to use the joint distribution of probabilities of minimum water discharges and the river runoff depth to characterize the severity and danger of durable low-flow periods. The copula theory is used to construct this distribution that enables to take account of differences in the types of one-dimensional probability distributions of ...

Assessment of Hydrological Drought Revisited

Water Resources Management, 2008
A variety of indices for characterising hydrological drought have been devised which, in general, are data demanding and computationally intensive. On the contrary, for meteorological droughts very simple and effective indices such as the Standardised Precipitation Index (SPI) have been used.

Hydrological identification of drought

Hydrological Processes, 1993
AbstractThe problem of drought identification is considered from a primarily hydrological viewpoint. The problems related to the definition, identification and prediction of drought have not yet been solved. Although rainfall data are analysed as the main indicator and characteristic of drought, other characteristics resulting from a rainfall deficit ...

Hydrologic Drought Atlas for Texas

Journal of Hydrologic Engineering, 2015
AbstractThis paper presents a hydrologic drought atlas for the state of Texas. The atlas depicts the spatial variation of drought severity for durations of 3, 6, 12, and 24 months corresponding to the return periods of 10, 25, 50, and 100 years.

Intensifying hydrologic drought in California

2022
<p>Drought has struck the southwest U.S. for the fourth time this millennium, reducing freshwater available to agriculture and urban centers.  We are bringing new insight by quantifying change in water in the ground using GPS elastic displacements, GRACE gravity, artificial reservoir levels, and snow models.

Analysis Methods for Hydrological Drought

2023
According to the World Meteorological Organization, the total economic impact of drought in Europe in the past 30 years was close to €100 billion. A recent publication by the European Environment Agency states that meteorological and hydrological droughts have become more frequent and severe in most of Europe, “being the highest in southern Europe ...
