Risk management has reduced vulnerability to floods and droughts globally1,2, yet their impacts are still increasing3. An improved understanding of the causes changing is therefore needed, but been hampered by a lack empirical data4,5. On basis global dataset 45 pairs events that occurred within same area, we show risk generally reduces faces difficulties in reducing unprecedented magnitude not previously experienced. If second event was much more hazardous than first, its impact almost...
Abstract This paper examines the projected changes in rainfall Southeast Asia (SEA) twenty-first century based on multi-model simulations of Regional Climate Downscaling/Coordinated Downscaling Experiment–Southeast (SEACLID/CORDEX–SEA). A total 11 General Circulation Models (GCMs) have been downscaled using 7 (RCMs) to a resolution 25 km × over SEA domain (89.5° E–146.5° E, 14.8° S–27.0° N) for two different representative concentration pathways (RCP) scenarios, RCP4.5 and RCP8.5. The...
As most variables describing the state of surface are not directly observable, we have to use land models in order reconstruct an estimate their evolution. These large‐scale often require high‐quality forcing data with a subdiurnal sampling. Building these sets is major challenge but essential step for estimating water budget, which crucial part climate change prediction. To study interannual variability conditions over last half century, built 53‐year set, named NCC. NCC has 6‐hourly time...
Since its launch in March 2002, the Gravity Recovery and Climate Experiment (GRACE) mission has been measuring global time variations of Earth's gravity field with a current resolution ∼500 km. Especially over continents, these measurements represent integrated land water mass, including surface waters (lakes, wetlands rivers), soil moisture, groundwater, snow cover. In this study, we use GRACE solutions computed by Ramillien et al. (2005a) through an iterative inversion monthly geoids from...
Abstract Flash floods have long been common in Asian cities, with recent increases urbanization and extreme rainfall driving increasingly severe frequent events. Floods urban areas cause significant damage to infrastructure, communities the environment. Numerical modelling of flood inundation offers detailed information necessary for managing risk such contexts. This study presents a calibrated model using referenced photos, an assessment influence four events on water depth area Hanoi...
Abstract Numerous studies have examined the changes in streamflow Mekong River Basin (MRB) using observations and hydrological modeling; however, there is a lack of integrated modeling that explicitly simulate natural human‐induced flood dynamics over entire basin. Here we river‐floodplain‐reservoir inundation MRB for 1979–2016 period newly integrated, high‐resolution (~5 km) river hydrodynamics‐reservoir operation model. The framework based on river‐floodplain hydrodynamic model CaMa‐Flood...

High-resolution climate projections are mandatory for many applications and impact assessments in environmental management studies. In response to the needs Vietnam, this study constructs a new precipitation temperature daily dataset at high spatial resolution of 0.1° × 0.1°, based on outputs 35 global models (GCMs) from Coupled Model Intercomparison Project Phase 6 (CMIP6). The Bias Correction Spatial Disaggregation (BCSD) method is adopted bias-correct monthly GCM simulations using...
The Gravity Recovery and Climate Experiment (GRACE) mission provides measurements of spatiotemporal change in land water storage that may improve simulation results surface models (LSMs). We show a transfer scheme recently developed within the Organising Carbon Hydrology Dynamic Ecosystems (ORCHIDEE) LSM significantly improves simulated storage. Over large tropical rivers basins, model without provide smaller amplitudes than observed by GRACE. Including accounts for stored river systems...

Abstract The performance of 28 CMIP6 models in simulating the Southeast Asian (SEA) climate is investigated. An evaluation methodology developed to evaluate spatiotemporal patterns precipitation, near‐surface temperature, and 850‐hPa wind. Mean annual cycles temperature rainfall are assessed separately over Indochina, Maritime Continent, Philippines; summer winter seasons selected for studying spatial patterns. Within these distinctions, statistics comparing reference data calculated....
Abstract. As the adverse impacts of hydrological extremes increase in many regions world, a better understanding drivers changes risk and is essential for effective flood drought management climate adaptation. However, there currently lack comprehensive, empirical data about processes, interactions, feedbacks complex human–water systems leading to impacts. Here we present benchmark dataset containing socio-hydrological paired events, i.e. two floods or droughts that occurred same area. The...
Abstract This study comprehensively assesses the performance of 29 Coupled Model Intercomparison Project Phase 6 (CMIP6) Global Climate Models (GCMs) and their ensemble mean (ENS_MEAN) over Vietnam. The spatiotemporal variability near-surface temperature precipitation is thoroughly evaluated for 30-year historical period 1985–2014. Results show that models can reasonably reproduce observational annual cycles spatial distribution precipitation, though performances vary across seven climatic...
