Drought Definition: A Hydrological Perspective
2000This paper summarises different techniques for defining a drought. Hydrologists as distinct from economists or social scientists define drought according to water deficits in some component of the hydrological cycle (precipitation, soil moisture, river flow and groundwater) or the impact on the level of service provided to public water supply ...

Analysis of Hydrological Drought
2012This chapter, entitled Analysis of hydrological drought is the first part of a self author’s work. It deals with a comprehensive analysis of hydrological drought. This chapter is divided into several subchapters. The first deals with the analysis of hydrological drought in the rivers profiles in Slovakia.

Indices of hydrological drought in Israel
Journal of Hydrology, 1987Abstract Indices of drought are formulated and examined on annual volumes of streamflow in Israel. Drought is defined as a severe shortage in the appearance of natural waters with respect to normal for place and time. The term severe shortage means here a deep, continuous and widely extended shortage.

Socio-hydrological modelling to manage and mitigate hydrological droughts
2021<p>Managing water-human systems in times of water shortage and droughts is key to avoid overexploitation and reduce drought impacts. Drought policies are designed to structure water management response and avoid crisis management, aiming to sustain both environmental and anthropogenic water demand.

Hydrological Drought Occurrence in Slovakia
2018The chapter presents the problem of drought and describes its classification and methods of assessing this risk. The aim of this chapter is to identify statistically significant trends in streamflow characteristics of low water content in the Eastern Slovakia, which are used in the evaluation of hydrological drought.

Indices for Meteorological and Hydrological Drought
2021This review chapter describes two physical forms of drought, meteorological and hydrological drought, and introduces a variety of specialized drought indices which may be used to quantify the intensity and severity of those drought forms. Meteorological and hydrological drought indices include the Palmer drought severity index (PDSI), rainfall deciles,

Hydrologic Drought Change Detection
Natural Hazards Review, 2019AbstractThis study detects changes in hydrologic drought indices (HDIs), including magnitude (i.e., daily mean, low flows, and flow quantiles), variability (i.e., coefficient of variation), and dur...

Drought influences on hydrological regimes
Persistent drought conditions may alter catchment response to precipitation, both during and after the drought period. Drought impacts on vegetation and hydrological dynamics may persist beyond the drought event, challenging accurate streamflow forecasting especially under flooding conditions.Alessia Matano +4 more

Mapping Hydrological Droughts Using Hydrological Profiles
Le développement de l’outil ProfHyl répond à la nécessité de disposer d’un dispositif intégré pour la visualisation spatiale et longitudinale des débits de référence des cours d’eau français. Conçu dans le cadre du partenariat INRAE–OFB, ProfHyl s’appuie sur la carte nationale des débits réglementaires et propose une approche combinant une cartographieAndréassian, Vazken +3 more
