Estimates of wind power and radiative near-inertial internal wave flux
(Ocean Dynamics, 2020-09-09)Energy transfer mechanisms between the atmosphere and the deep ocean have been studied for many years. Their importance to the ocean’s energy balance and possible implications on mixing are widely accepted. The slab model ... -
Global tide simulations with ICON-O: testing the model performance on highly irregular meshes
(Ocean Dynamics, 2020-12-08)The global tide is simulated with the global ocean general circulation model ICON-O using a newly developed tidal module, which computes the full tidal potential. The simulated coastal M2 amplitudes, derived by a discrete ... -
Tidal response to sea level rise and bathymetric changes in the German Wadden Sea
(Ocean Dynamics, 2020-06-07)Tidally dominated coasts are directly affected not only by projected rise in mean sea level, but also by changes in tidal dynamics due to sea level rise and bathymetric changes. By use of a hydrodynamic model, which covers ... -
Improvements in turbulence model realizability for enhanced stability of ocean forecast and its importance for downstream components
(Ocean Dynamics, 2020-02-24)The numerical stability of ocean circulation models is of high significance in operational forecasting. A substantial improvement in numerical stability of the 3D-ocean model HBM could be achieved by the implementation of ... -
Interactions between barotropic tides and mesoscale processes in deep ocean and shelf regions
(Ocean Dynamics, 2020-03-14)The interactions between barotropic tides and mesoscale processes were studied using the results of a numerical model in which tidal forcing was turned on and off. The research area covered part of the East Atlantic Ocean, ... -
Sea-state contributions to sea-level variability in the European Seas
(Ocean Dynamics, 2020-10-02)The contribution of sea-state-induced processes to sea-level variability is investigated through ocean-wave coupled simulations. These experiments are performed with a high-resolution configuration of the Geestacht COAstal ... -
A probabilistic approach to estimating residential losses from different flood types
(Natural Hazards, 2020-12-02)Residential assets, comprising buildings and household contents, are a major source of direct flood losses. Existing damage models are mostly deterministic and limited to particular countries or flood types. Here, we compile ... -
A local scale flood vulnerability assessment in the flood-prone area of Khyber Pakhtunkhwa, Pakistan
(Natural Hazards, 2020-10-24)The central part of Khyber Pakhtunkhwa, Pakistan, is a highly flood-prone area of the province. The lives and assets of local communities are deeply vulnerable, attributed to the recurrence of seasonal floods. This concern ... -
Pan-European hydrodynamic models and their ability to identify compound floods
(Natural Hazards, 2020-03-21)The interaction between storm surges and inland run-off has been gaining increasing attention recently, as they have the potential to result in compound floods. In Europe, several flood events of this type have been recorded ... -
Effects of model calibration on hydrological and water resources management simulations under climate change in a semi-arid watershed
(Climatic Change, 2020-11-18)Semi-arid regions are known for erratic precipitation patterns with significant effects on the hydrological cycle and water resources availability. High temporal and spatial variation in precipitation causes large variability ... -
How evaluation of hydrological models influences results of climate impact assessment—an editorial
(Climatic Change, 2020-12-07)This paper introduces the Special Issue (SI) “How evaluation of hydrological models influences results of climate impact assessment.” The main objectives were as follows: (a) to test a comprehensive model calibration/validation ... -
Comparison of two model calibration approaches and their influence on future projections under climate change in the Upper Indus Basin
(Climatic Change, 2020-11-10)This study performs a comparison of two model calibration/validation approaches and their influence on future hydrological projections under climate change by employing two climate scenarios (RCP2.6 and 8.5) projected by ... -
What drives relocation policies in the Maldives?
(Climatic Change, 2020-11-20)The predominant responses to rising sea levels are in situ adaptations. However, increasing rates of sea-level rise will render ex situ adaptations—in the form of relocations—inevitable in some low-lying coastal zones. ... -
Performance evaluation of global hydrological models in six large Pan-Arctic watersheds
(Climatic Change, 2020-11-24)Global Water Models (GWMs), which include Global Hydrological, Land Surface, and Dynamic Global Vegetation Models, present valuable tools for quantifying climate change impacts on hydrological processes in the data scarce ... -
Streamflow-based evaluation of climate model sub-selection methods
(Climatic Change, 2020-10-10)The assessment of climate change and its impact relies on the ensemble of models available and/or sub-selected. However, an assessment of the validity of simulated climate change impacts is not straightforward because ... -
How evaluation of global hydrological models can help to improve credibility of river discharge projections under climate change
(Climatic Change, 2020-10-12)Importance of evaluation of global hydrological models (gHMs) before doing climate impact assessment was underlined in several studies. The main objective of this study is to evaluate the performance of six gHMs in simulating ... -
Attitudes towards climate change migrants
(Climatic Change, 2020-03-18)While climate change has become a salient political and social issue in Western societies, we know relatively little about how these societies will react to one of the potentially important consequences of climate change: ... -
Climate change, ecosystem services and migration in the Marshall Islands: are they related?
(Climatic Change, 2020-04-10)As one of the lowest-lying island nation states in the world, the Republic of the Marshall Islands is vulnerable to sea level rise, flooding and the associated impacts on soil and water salinity. Persistent drought is ... -
