Hydrological aspects of droughts
Hydrological droughts are characterized by changes in surface and subsurface water supplies. The signs of this kind of drought tend to lag behind agricultural and meteorological droughts. The impacts of hydrological droughts can last for years beyond the initial onset of the drought. The severity of the drought depends on location and factors. The International Hydrology Series is a collaborative publishing program between UNESCO, Paris and Cambridge University Press. It contains monographs describing research activities in hydrology and the study of hydrological hazards which have been sponsored by the UNESCO International Hydrology Program.
Hydrological droughts are typically out of phase with or lag the occurrence of meteorological and agricultural droughts. More time elapses before precipitation deficiencies show up in these components of the hydrological system. As a result, impacts are out of phase with those in other economic sectors. Drought under global warming: areview Aiguo Dai∗ This article reviews recent literature on drought of the last millennium, followed by an update on global aridity changes from to Projected future aridity is presented based on recent studies and .
Analysis and forecasting of droughts are important for water resources management. The objective of this study is to analyze hydrological droughts using the joint drought probability distribution derived from the copula theory and analyze drought return periods upstream of Namhan River in the upper Han River basin, Korea.

In this chapter we focus on the assessment of various aspects of hydrology-related droughts and show that a process-based hydrological model has a lot to offer for drought by: 2. There are three types of Droughts. Hydrological: when the flow in the rivers is below average year, it is hydrological drought.
Meteorological: when the rainfall is below average, its meteorological drought. Agricultural: when the moisture in soil. Generally, drought can be divided into four types: Meteorological drought, Agricultural drought, Hydrological drought and Social-economic drought . Meteorological drought is.
A drought event has the following major components (Dracup et al., ) as derived from Fig. 1 which include: (a) Drought initiation time (t i): it is the starting of the water shortage period, which indicates the beginning of a drought.(b) Drought termination time (t e): it is the time when the water shortage becomes sufficiently small so that drought conditions no longer by: Hydrological drought is a textbook for university students, practising hydrologists and researchers.
The main scope of this book is to provide the reader with a comprehensive review of processes and estimation methods for streamflow and groundwater drought.

This paper presents a short summary of a report on ‘Drought Events in Europe’ (Bradford, ) commissioned by the Space Applications Institute (SAI) of the EC Joint Research Centre to identify particular drought-related topics for discussion during the workshop on ‘Drought and Drought Mitigation in Europe’.This report was based on a review of recent Cited by: Hydrological droughts are usually out of phase with or lag the occurrence of meteorological and agricultural droughts.

1 Introduction Drought is widely recognised as a complex, multifaceted phenomenon (e.g. Van Loon, ).Cited by: The Danube River Basin is shared by 19 countries and there is no river basin in the world shared by so many nations.
Europe’s second largest river basin with a total 2 area of aboutkm is also home to 83 million people of different cultures. A drought or drouth is an event of prolonged shortages in the water supply, whether atmospheric (below-average precipitation), surface water or ground water.A drought can last for months or years, or may be declared after as few as 15 days.
It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy. hydrological drought). The objective of this study was to assess the effects of hydrological droughts on the water quality in Mazandaran Province, Iran, based on analysis of the low flow index and existing water quality data.

The transfer of energy and water between the land surface and lower atmosphere within the. duration of all three major droughts is substantially smaller for the recharge drought than for the hydrological droughts (heads and streamflow). The drought clearly reflects this. A minor drought in the recharge has been observed, whereas droughts over days occur in the groundwater heads and the Size: KB.
