Hydrological Drought - a Study across Europe
Aiming at a better understanding of drought causes and processes, the present study investigated hydrological drought characteristics in space and time and their large-scale atmospheric driving forces in Europe. On the basis of daily streamflow data of more than 600 European rivers for 1962-1990, …

Hydrological Drought Analysis for Seven North Georgia Watersheds (1970-2000)
<p>Drought is a prolonged reduction in precipitation which may result in significant effects on local ecosystems, watersheds, and water sources, with the potential to have negative impacts on human populations. Normalized indexes can be used to characterize drought magnitudes and frequencies using …

Evaluation of future meteorological and hydrological drought in the Rufiji basin
… the critical need to understand the dynamics of drought patterns in the Rufiji Basin, Tanzania, under both current and future climatic scenarios. Droughts, with their profound impact on the socio-economic fabric and environmental sustainability of the region, represent a significant challenge in …

Attribution of the 2015-2016 hydrological drought in KwaZulu-Natal to anthropogenic climate change
… other provinces in South Africa suffered from drought conditions. Drought can have negative impacts on the environment, society and the economy. Climate change is predicted to exacerbate extreme events such as droughts that would adversely affect already vulnerable regions such as KZN. The main …

Potential impacts of climate change and land-use change on hydrological drought in the Western Cape (South Africa)
… Africa) recently witnessed the most severe drought on record. The meteorological drought, which was characterised by below-normal rainfall for three consecutive years (2015 – 2017), cascaded to agricultural and then hydrological drought, resulting in devastating socio-economic consequences. …

The Influence of Anthropogenic Climate Change on the 2015-2017 Hydrological Drought in the South-Western Cape, South Africa
… in a three-year compound hydro-meteorological drought event in the Province. The 2015−2017 Western Cape hydro-meteorological drought was the worst drought event since 1904 and caused severe unprecedented water shortages throughout the Western Cape region, with many municipal water supply …

Atmospheric circulation and sea surface temperature anomalies during the dry summers of 2001/02, 2002/03 and 2003/04 in Southern Africa
Drought is a phenomenon associated with the lack or shortage of water. It means less than normal or no water is available. It primarily originates from lack of precipitation. Lack of precipitation leads to depletion of storage of I. soil moisture that results in dry land crop failure and dying-off …

European droughts under climate change: projections and uncertainties
Droughts are one of the most damaging natural hazards, and anthropogenic climate change has and will continue to alter their characteristics. Better understanding of changes in drought characteristics under potential future climates is vital for managing drought risks and impacts, yet projections …

Potential impacts of climate change on hydrological droughts in the Limpopo river basin
Climate change possibly intensifies hydrological droughts and reduces water availability in river basins. Despite this, most research on climate change effects in southern Africa has focused exclusively on meteorological droughts. This thesis projects the potential effect of climate change on the …

Development and analysis of a homogeneous long-term precipitation network (1850-2015) and assessment of historic droughts for the island of Ireland
… for understanding emerging changes to the hydrological cycle. Given the paucity of long-term quality assured precipitation records in Ireland this thesis expands the existing catalogue of long-term monthly precipitation records for the Island by recovering and digitising archived data. …

A Dendroclimatic Investigation of Southwestern Saskatchewan
… water resources has increased vulnerability to hydrological drought. Because few instrumental records exceed 100 years, climate proxies are used to extend the historical record of natural variability. Understanding the frequency, magnitude, and duration of past climate extremes allows …

Understanding drought propagation and its implications for drought management
Droughts have been recognized as one of the most complex natural disasters, especially because they involve interactions between numerous climatological, hydrological and human processes. During a drought event, deficits in precipitation gradually translate into deficits in soil moisture, …

Understanding the characteristics of droughts over Eastern Africa in past and future climates
Drought poses a threat to socio-economic activities across eastern Africa and its river basins. While there are indications that global warming may continue to enhance evaporation and intensify droughts at all scales, most drought projections over eastern Africa are based on rainfall alone and are …

A remote sensing assessment of irrigation land use land cover change in the Sokoto Rima River Basin, Nigeria
… 1950 was used to analyze the meteorological and hydrological drought pattern at four locations within the basin and was found to be a moderate drought. The SPEI data was then correlated with the Global Surface Water Explorer data to observe the surface water dynamics and to show the drought …

Drinking Water Infrastructure Assessment with Teleconnection Signals, Satellite Data Fusion and Mining
… Vegas Wash. In addition, more than a decade of drought has caused a sharp drop by about 100 feet in the elevation of Lake Mead. These hydrological processes in the drought event led to the increased concentration of total organic carbon (TOC) and total suspended solids (TSS) in the lake. TOC in …

Assessment of the influence of Nonstationary Climate on Extreme Hydrology of Southwestern Canada
… time, the region’s resilience to the impacts of hydrological extremes, floods and droughts is challenged by the increasing frequency of these extreme events. In addition, increased winter temperatures over the past century have led to declines in winter snowpack and caused earlier snowmelt, …
