Abstract. Landslides are a ubiquitous hazard in terrestrial environments with slopes, incurring human fatalities urban settlements, along transport corridors and at sites of rural industry. Assessment landslide risk requires high-quality databases. Recently, global databases have shown the extent to which landslides impact on society identified areas most risk. Previous analysis has focused rainfall-triggered over short ∼ 5-year observation periods. This paper presents spatiotemporal dataset fatal non-seismic landslides, covering period from January 2004 December 2016. The data show that total 55 997 people were killed 4862 distinct events. spatial distribution is heterogeneous, Asia representing dominant geographical area. There high levels interannual variation occurrence landslides. Although more active years coincide recognised patterns regional rainfall driven by climate anomalies, modes (such as El Niño–Southern Oscillation) cannot yet be related landsliding, requiring 30+ years.

Hydrological drought explained

Wiley Interdisciplinary Reviews Water, Journal Year: 2015, Volume and Issue: 2(4), P. 359 - 392

Published: April 14, 2015

Drought is a complex natural hazard that impacts ecosystems and society in many ways. Many of these are associated with hydrological drought (drought rivers, lakes, groundwater). It is, therefore, crucial to understand the development recovery drought. In this review an overview given current state scientific knowledge definitions, processes, quantification Special attention influence climate terrestrial properties (geology, land use) on characteristics role storage. Furthermore, debate about use usefulness different indicators highlighted recent advances monitoring prediction mentioned. Research projections for future summarized. This also briefly touches upon link issues related management. Finally, four challenges research defined relate international initiatives such as Intergovernmental Panel Climate Change ( IPCC ) ‘Panta Rhei’ decade International Association Hydrological Sciences IAHS ).

Flood risk and climate change: global and regional perspectives

Hydrological Sciences Journal, Journal Year: 2013, Volume and Issue: 59(1), P. 1 - 28

Published: Dec. 20, 2013

A holistic perspective on changing rainfall-driven flood risk is provided for the late 20th and early 21st centuries. Economic losses from floods have greatly increased, principally driven by expanding exposure of assets at risk. It has not been possible to attribute rain-generated peak streamflow trends anthropogenic climate change over past several decades. Projected increases in frequency intensity heavy rainfall, based models, should contribute precipitation-generated local flooding (e.g. flash urban flooding). This article assesses literature included IPCC SREX report new published since, includes an assessment changes seven regions considered recent report—Africa, Asia, Central South America, Europe, North Oceania Polar regions. Also considering newer publications, this consistent with finding that impacts characteristics are highly sensitive detailed nature those presently we only low confidence1 numerical projections magnitude or resulting change.Editor D.

Warming of the Earth climate system is unequivocal. That changes affect stability natural and engineered slopes have consequences on landslides, also undisputable.

Future changes to the intensity and frequency of short-duration extreme rainfall

Reviews of Geophysics, Journal Year: 2014, Volume and Issue: 52(3), P. 522 - 555

Published: July 25, 2014

Evidence that extreme rainfall intensity is increasing at the global scale has strengthened considerably in recent years. Research now indicates greatest increases are likely to occur short-duration storms lasting less than a day, potentially leading an increase magnitude and frequency of flash floods. This review examines evidence for subdaily intensification due anthropogenic climate change describes our current physical understanding association between atmospheric temperature. We also examine nature, quality, quantity information needed allow society adapt successfully predicted future changes, discuss roles observational modeling studies helping us better understand processes can influence characteristics. conclude by describing types research required produce more thorough relationships local-scale thermodynamic effects, large-scale circulation, intensity.

Global Increasing Trends in Annual Maximum Daily Precipitation

Journal of Climate, Journal Year: 2012, Volume and Issue: 26(11), P. 3904 - 3918

Published: Dec. 14, 2012

Abstract This study investigates the presence of trends in annual maximum daily precipitation time series obtained from a global dataset 8326 high-quality land-based observing stations with more than 30 years record over period 1900 to 2009. Two complementary statistical techniques were adopted evaluate possible nonstationary behavior these data. The first was Mann–Kendall nonparametric trend test, and it used existence monotonic trends. second generalized extreme value analysis, determine strength association between extremes globally averaged near-surface temperature. outcomes are that statistically significant increasing can be detected at scale, close two-thirds showing increases. Furthermore, there is temperature, median intensity changing proportion changes mean temperature rate 5.9% 7.7% K−1, depending on method analysis. ratio robust irrespective length or considered not strongly biased by uneven coverage Finally, distinct meridional variation, greatest sensitivity occurring tropics higher latitudes minima around 13°S 11°N. uncertainty near equator because limited number sufficiently long records, remains an urgent need improve data collection this region better constrain future tropical precipitation.
