Abstract Accurately predicting regional-scale water fluxes and states remains a challenging task in contemporary hydrology. Coping with this grand challenge requires, among other things, model that makes reliable predictions across scales, locations, variables than those used for parameter estimation. In study, the mesoscale hydrologic (mHM) parameterized multiscale regionalization technique is comprehensively tested 400 European river basins. The states, constrained using observed...
Abstract Droughts diminish crop yields and can lead to severe socioeconomic damages humanitarian crises (e.g., famine). Hydrologic predictions of soil moisture droughts several months in advance are needed mitigate the impact these extreme events. In this study, performance a seasonal hydrologic prediction system for drought forecasting over Europe is investigated. The based on meteorological forecasts North American Multi-Model Ensemble (NMME) that used drive mesoscale model (mHM). skill...
Abstract Environmental models tend to require increasing computational time and resources as physical process descriptions are improved or new incorporated. Many‐query applications such sensitivity analysis model calibration usually a large number of evaluations leading high demand. This often limits the feasibility rigorous analyses. Here we present fully automated sequential screening method that selects only informative parameters for given output. The requires is approximately 10 times...
Abstract. Heterogeneity of landscape features like terrain, soil, and vegetation properties affects the partitioning water energy. However, it remains unclear to what extent an explicit representation this heterogeneity at sub-grid scale distributed hydrological models can improve consistency robustness such models. In study, process complexity arising from topography was incorporated into mesoscale Hydrologic Model (mHM). Seven study catchments across Europe were used test whether (1)...

Among the products archived on a daily basis are five operational forecasts, three analyses, one reanalysis product. have hourly to temporal resolution 2.5–50-km spatial resolution. To date contains 394 TB data while 368 GB new added every night. in CF-1.6-compliant netCDF-4 format. available online ( https://caspar-data.ca ) since June...
Abstract A method is presented for determining steady‐state capture zones in three dimensions around horizontal drains and vertical wells homogeneous, anisotropic aquifers a uniform flow field. Equations are drawdown velocity vector components wells. Using these equations, second‐order Runge‐Kutta particle tracking algorithm applied to trace streamlines dimensions. By large number of particles, it possible determine areas where occurs particles escape capture. The resulting 3D diagrammed as...
In water-scarce areas, the reclamation of wastewater through advanced water treatment and subsequent reinjection into depleted aquifers is an increasingly attractive management option. However, such injection can trigger a range water-sediment interactions which need to be well understood quantified ensure sustainable operations. this study, reactive transport modeling was used analyze quantify interacting hydrogeochemical processes controlling mobilization fluoride phosphate during highly...
Abstract Reuse of wastewater through a combination advanced treatment (AWT) and managed aquifer recharge (MAR) is an important water management option. As integral part any AWT‐MAR system, the geochemical compatibility recharged with targeted must be assessed to avoid groundwater quality deterioration. Although short‐term field experiments may uncover potentially concerning sediment‐water disequilibria, analysis often required understand long‐term impacts large‐scale MAR. Here, we develop...
Fluoride-bearing apatite minerals such as fluorapatite (FAP: Ca10(PO4)6F2) and related carbonate-rich fluorapatites (CFA: Ca10(PO4)5(CO3,F)F2), which occur ubiquitously trace components of rocks sediments, may act sources for geogenic groundwater fluoride contamination. CFA dissolution often occurs in conjunction with declining dissolved calcium concentrations. Therefore, managed aquifer recharge (MAR) operations using deionised or low source water are at risk disturbing the naturally...
Abstract A new, azimuthally sensitive gamma-at-bit imaging tool has been designed for use in geosteering and to provide gamma measurements very close the bit while drilling. It uses binned azimuthal from four scintillation ray detectors spaced at ninety degrees around collar. Continuous image logs are recorded telemetered main LWD string ultimately compressed form surface, whether is sliding or rotating. When rotating, data can be quadrants, octants, hexadecants. sliding, quadrant recorded....
Groundwater, the most important water resource and largest distributed store of fresh in world, supports sustainability groundwater-dependent ecosystems resilient sustainable economy future. However, groundwater level decline many parts world has occurred as a result combination climate change, land cover change abstraction from aquifers. This study investigates determination contributions these factors to changes with HydroSight model. The unconfined superficial aquifer Gnangara region...
