Abstract. Intercatchment groundwater flows (IGFs), defined as across topographic divides, can occur regional that bypass headwater streams and only drain into the channel further downstream or directly to sea. However, also be diverted adjacent river basins due geological features (e.g., faults, dipping beds highly permeable conduits). Even though intercatchment a significant part of water balance, they are often not considered in hydrological studies. Yet, assuming this process negligible...
Abstract. Streamflow is often the only variable used to evaluate hydrological models. In a previous international comparison study, eight research groups followed an identical protocol calibrate 12 models using observed streamflow of catchments within Meuse basin. current we quantify differences in five states and fluxes these process-based with similar performance, systematic comprehensive way. Next, assess model behavior plausibility by ranking for set criteria remote-sensing data...
Abstract. Future hydrological behavior in a changing world is typically predicted based on models that are calibrated past observations, disregarding systems and, therefore, model parameters may change as well. In reality, experience almost continuous over wide spectrum of temporal and spatial scales. particular, there growing evidence vegetation adapts to climatic conditions by adjusting its root zone storage capacity, which the key parameter any terrestrial system. addition, other species...
Many impact assessment studies rely on hydrological and hydrodynamic (hydro) models.These models typically require a large set of parameters derived from different datasets hence manual setup can be time consuming hard to reproduce.HydroMT (Hydro Model Tools) is an open-source Python package that aims make the process building model instances analyzing results automated reproducible.The provides common interface data instances, workflows transform into based (hydrological) GIS statistical...
Abstract The spatiotemporal dynamics of water volumes stored in the unsaturated root zone are a key control on response terrestrial hydrological systems. Robust, catchment‐scale root‐zone soil moisture estimates thus critical for reliable predictions river flow, groundwater recharge, or evaporation. Satellites provide near‐surface that can be used to approximate content entire through Soil Water Index (SWI). characteristic time length ( T , days), as only parameter SWI approach,...
Abstract. The wflow_sbm hydrological model, recently released by Deltares, as part of the Wflow.jl (v0.7.3) modelling framework, is being used to better understand and potentially address multiple operational water resource planning challenges from a catchment scale national continental global scale. free open-source distributed framework written in Julia programming language. development wflow_sbm, model structure, equations functionalities are described detail, including example...
Abstract. International collaboration between research institutes and universities is a promising way to reach consensus on hydrological model development. Although comparison studies are very valuable for international cooperation, they do often not lead clear new insights regarding the relevance of modelled processes. We hypothesise that this partly caused by complexity methods used, which focus too much good overall performance instead focusing variety specific events. In study, we use an...
This study investigates the influence of DEM resolutions on flood inundation simulation. Sanyei drainage area Tainan City is taken as a case study. The catchment 43.7 km2 with main stream 6.7km and elevations running from 2 m to 30 m. uses 1x1 LiDAR basis. To do pure 2D simulation, channel elevation adjusted based cross-sectional measurements. 1x1m later used basis aggregate several DEMs including: 5x5m, 10x10m, 20x20m, 40x40m. Five models were built 5 mentioned above same model setting....
Abstract. Streamflow is often the only variable used to constrain hydrological models. In a previous international comparison study, eight research groups followed an identical protocol calibrate total of twelve models using observed streamflow catchments within Meuse basin. current we hypothesize that these process-based with similar performance have representations internal states and fluxes. We test our hypothesis by comparing fluxes between assess their plausibility remotely-sensed...

Abstract. This paper investigates the influence of multi-decadal climatic variability on temporal evolution root zone storage capacities (Sr,max) and its implications for streamflow predictions at catchment scale. Through a comprehensive analysis 286 catchments across Europe US, we analyse deviations in evaporative ratios (IE) from expected values based aridity (IA) their subsequent impact Sr,max predictions. Our findings reveal that while do not strictly adhere to specific parametric Budyko...
Abstract. This paper investigates the influence of multi-decadal climatic variability on temporal evolution root zone storage capacities (Sr,max) and its implications for streamflow predictions in Meuse basin. Through a comprehensive analysis 286 catchments across Europe US that are hydro-climatically comparable to basin, we construct inter-decadal distributions past deviations evaporative ratios (IE) from expected values based catchment aridity (IA). These ΔIE were then used estimate...

<p>Models calibrated on the past are often used to predict future hydrological behavior in a changing world, disregarding that systems, hence model parameters, will change as well. Even if we aware of non-stationarity impeded by our limited knowledge how meaningfully implement this models. Yet, ecosystems likely adapt response climate and other species might become dominant, both under natural anthropogenic influence. The root-zone storage capacity is an important parameter,...
Abstract This paper presents an analysis of future research and development needs to assess the effectiveness nature-based solutions for climate adaptation in watersheds at scale using hydrological models. Two main questions are addressed: what extent model approaches able support decision making on adaptation, how well is this embedded broader planning process? To research, case studies Bhutan, Zimbabwe Netherlands presented. The Climate Risk Informed Decision Analysis approach used...
In this paper, we present a model of hysteresis motor based on Maxwell's equations coupled with the Jiles-Atherton (J-A) solved by finite element method. The aim work is to validate such comparison experimental results (electromagnetic torque, voltage, current). We also an analysis when imposing current or voltage in 2D vector potential formulation.

Understanding extreme discharge behavior is of importance for flood design and risk management. For example, estimates large return periods such as the 100-year period or higher are often needed a basis hazard maps dike design. Yet, frequency analysis based on decade-long records show uncertainty these frequencies, among others due to statistical from distribution parameters.  This not case shape parameter, key parameter that describes upward downward curvature tail thus an...
