Abstract. Drought monitoring and early warning (M & EW) systems are a crucial component of drought preparedness. M EW typically make use indicators such as the Standardised Precipitation Index (SPI), but not widely used in UK. More generally, tools have been well developed for hydrological (i.e. streamflow) drought. To fill these research gaps, this paper characterises meteorological droughts, propagation from one to other, using SPI related Streamflow (SSI), with objective improving...
Abstract. Drought is a natural hazard that can cause wide range of impacts affecting the environment, society, and economy. Providing an impact assessment reducing vulnerability to these for regions beyond local scale, spanning political sectoral boundaries, requires systematic detailed data regarding impacts. This study presents diversity drought across Europe based on European Impact report Inventory (EDII), unique research database has collected close 5000 reports from 33 countries. The...
Abstract The summer of 2022 was particularly notable for the prolonged and extensive hot dry conditions experienced across UK. resultant drought had widespread impacts prompted much discussion about continuing vulnerability UK to drought, in context anthropogenic warming. Here, we briefly describe evolution before focusing on severity rainfall, river flow, soil moisture groundwater level deficits from 2022, placing event into a historical addressing drought. We also consider whether is part...
Abstract. Drought monitoring and early warning is an important measure to enhance resilience towards drought. While there are numerous operational systems using different drought indicators, no consensus on which indicator best represents impact occurrence for any given sector. Furthermore, thresholds widely applied in these indicators but, date, little empirical evidence exists as trigger impacts society, the economy, ecosystems. The main obstacle evaluating commonly used a lack of...
Abstract. Hydrological droughts occur in all climate zones and can have severe impacts on society the environment. Understanding historical drought occurrence quantifying severity is crucial for underpinning risk assessments developing management plans. However, hydrometric records are often short capture only a limited range of variability. The UK no exception: numerous over past 50 years been well captured by observations from dense network. lack long-term means that our understanding...
Abstract. Drought events and their impacts vary spatially temporally due to diverse pedo-climatic hydrologic conditions, as well variations in exposure vulnerability, such demographics response actions. While hazard severity frequency of past drought have been studied detail, little is known about the effect management strategies on actual how perceived by relevant stakeholders. In a continental study, we characterised assessed perceptions two recent (2018 2019) Europe examined relationship...
Between 2016 and 2019, the UK was in a period of prolonged dry conditions with varying spatial temporal foci. We look at rainfall, river flows, soil moisture drought impacts leading up to including heatwave 2018, following year, placing events into historical context. Using incident data from regulators, we also explore for this period.
Abstract Precipitation‐based drought indices are most commonly used in monitoring and early warning systems whereas impacts of often related to other domains the hydrological cycle such as streamflow. Precipitation droughts do not always coincide with streamflow droughts, propagation from precipitation is affected by climate, catchment properties, human influences. For ungauged catchments it question what extent solely based on or (more recently developed) meteorological that include...
Abstract. The 2022 European drought has underscored critical deficiencies in water management. This paper explores these shortcomings and suggests a way forward for risk Data this study was gathered through continent-wide survey of managers involved event. collected 481 responses from 30 countries is comprised 19 questions concerning sectorial impact the 55 regions responders management practices their organizations.

The flooding in winter 2015/2016 was one of the most extraordinary hydrological episodes witnessed UK recent decades. defined by a succession severe storms, bringing extreme rainfall and associated widespread across northern western regions. For UK, December 2015 wettest month (for any calendar month) it second (December–February) series from 1910, while number new records were established for accumulations over shorter timescales (McCarthy et al., 2016; Burt, 2016). response remarkable;...
Abstract. Hydrological models can provide estimates of streamflow pre- and post-observations, which enable greater understanding past hydrological behaviour, potential futures. In this paper, a new multi-objective calibration method was derived tested for 303 catchments in the UK, calibrations were used to reconstruct river flows back 1891, order much longer view variability, given brevity most UK flow records began post-1960.

Despite being one of the most damaging natural hazards, droughts and their spatiotemporal dynamics are typically not well understood. Great Britain, which is focus this work, has experienced many major drought episodes in past, causing a range socioeconomic environmental impacts. Here, we apply recently developed technique to identify characterise past droughts, using space-time connectivity extract events from monthly gridded precipitation dataset covering 1862–2015, without imposing fixed...
A warming climate is expected to alter the magnitude, frequency and spatial pattern of floods. The widespread flooding observed in UK Western Europe over winter half-year 2023/24 followed on from a number other notable floods 2013/14, 2015/16 2019/20. However, detecting climate-driven trend river flows complicated by influence internal variability relatively short observational records. End-to-end probabilistic attribution that includes also remains challenging as hydrological responses do...
Drought events significantly challenge communities and ecosystems worldwide, emphasising the urgent need for effective predictive methods to facilitate proactive management mitigate their impacts. A clear gap exists between theoretical drought indices, such as SPI, SPEI, SSMI, real-world impacts of droughts. This study aims address this disparity by leveraging machine learning (ML) techniques predict reported impacts, using data from European Impact Database (EDID). variety ML algorithms,...
Abstract Drought is widely written about as a complex, multifaceted phenomenon, with complexity arising not just from biophysical drivers, but also human understanding and experiences of drought its impacts. This has led to proliferation different definitions indicators, creating challenge for the design monitoring early warning (MEW) systems, which are key component preparedness. Here, we report on social learning workshops conducted in United Kingdom aimed at improving operation MEW...
Between June 2019 and February 2020 the UK saw a succession of severe flood events. Many river flows in northern England, Midlands on both sides English/Welsh border exceeded their highest record, some defences were overwhelmed. The impact widespread, prolonged places, repeated flooding reinforces importance detailed analyses such events within historical context to inform assessment future risk changing world. After an extended dry period, lasting for well over two years parts United...
Abstract. Droughts in Thailand are becoming more severe due to climate change. Developing a reliable drought monitoring and early warning system (DMEWS) is essential strengthen country's resilience droughts. However, for DMEWS be valuable, the indicators provided stakeholders must have relevance tangible impacts on ground. Here, we analyse indicator-to-impact relationships Thailand, using combination of correlation analysis machine learning techniques (random forest). In analysis, study link...
