Abstract Accurate mapping of headwater streams and their flow status has important implications for understanding and managing water resources and land uses. However, accurate information is rare, especially in rugged, forested terrain. We developed a streamflow permanence classification model for f...

Abstract We present a methodology to quantify the impact of model structure and parametric uncertainty on formulations targeting biotransformation processes of Emerging Contaminants in subsurface water resources. The study is motivated by recognizing that modeling of bio‐mediated reactions of recalc...

Abstract Land evapotranspiration has a notable impact on the continental precipitation of India during monsoons. Given the heterogeneous land use and climate, India hosts many transition zones, which are hotspots for land‐atmosphere interactions. This work aims to study the soil moisture‐precipitati...

Abstract Droughts around the world have resulted in less annual streamflow relative to annual rainfall. The decrease in streamflow cannot be explained by changes in land‐use, precipitation or temperature alone. Rather, the decrease in annual streamflow has been linked to changes in annual rainfall‐p...

Abstract The soil above the water table in the shallow layers of the Earth is typically unsaturated, and understanding the complicated multiphase contact modes and interactions in unsaturated is crucial for accurately simulating multi‐physical field coupling and predicting foundation deformation in...

Abstract Mathematical models in engineering play an important role in understanding and predicting the behavior of a system. A mechanistic coupled liquid water, water vapor and heat transfer model incorporating kinetic phase change accounting for real‐time interfacial area between water and gas phas...

Abstract Blue‐green roofs (BGRs), compared to traditional green roofs, can provide enhanced water storage capacity for stormwater management and drought mitigation. However, the potential of utilizing stored water for external purposes, such as toilet flushing and lawn irrigation, remains underexplo...

Abstract The dynamics of suspended particulate matter (SPM) and SPM‐associated biological and physicochemical processes in a river vary under dry and wet weather conditions and hydraulic structures, which moves a free‐flowing river to a semi‐lacustrine environment. This study investigated the respon...

Abstract Fresh groundwater lenses (FGLs) are important freshwater resources for offshore reclaimed islands. However, previous studies usually neglected the dynamic evolution process of FGLs, which can last for decades in thin reclaimed islands. This study employed numerical simulation to analyze the...

Abstract Anthropogenic climate change and disrupted river network connectivity are major factors affecting freshwater fish richness. However, the distribution patterns of this parameter under the combined influence of climate change and reduced river connectivity resulting from hydroelectric develop...

Abstract A robustly calibrated and validated hydrodynamic model depicts flow patterns over a topographically complex floodplain with a heterogeneous main channel levee. Simulations highlight floodplain inundation dynamics for two conditions, the passage of sub‐bankfull and overbank flood waves. Sub‐...

Abstract Numerical solution of the one‐dimensional Richards equation (RE) accurately partitions precipitation into infiltration and runoff in capillary dominated soils. However, its application sometimes requires significant computational effort and presents reliability challenges. The Green and Amp...

Abstract Understanding the distribution of soil moisture is notoriously difficult in topographically complex regions that are subject to both large‐scale climate gradients and fine‐scale effects of terrain, vegetation, and soil structure. Remote sensing approaches capture large‐scale moisture patter...

Abstract There is a lack of Ordinary Differential Equation (ODE) formulations in numerical hydrology, contributing to the lack of application of canned adaptive timestep solvers; hence the continued dominance of fixed (e.g., Euler) timestep techniques despite their fundamental problems. In this pape...

Abstract Characterizing the impact of human actions on terrestrial water fluxes and storages at multi‐basin, continental, and global scales has long been on the agenda of scientists engaged in climate science, hydrology, and water resources systems analysis. This need has resulted in a variety of mo...

Abstract In this study, we investigated the coupling effect of sub‐core‐scale heterogeneity and miscibility on the development of flow pattern under drainage in porous media. We performed experiments with two Bentheimer sandstone cores (usually considered homogeneous) both with mild heterogeneity. F...

Abstract The agricultural sector is the biggest and least efficient water user, accounting for around 80% of total water use in North Africa, which is already strongly impacted by climate change with prolonged drought periods, imposing limitations on irrigation water availability. The objective of t...

Abstract Harmful algal blooms have large impacts on aquatic ecosystem and human health. Nutrient enrichment, in combination with warm water temperatures, high sunlight availability, and low water turbulence, have been proven to be major factors driving algal blooms. In this study, lake eutrophicatio...

Abstract Macrobenthic invertebrates are widely distributed on sediments, and the micro‐morphology such as burrows and sand mounds due to their bioturbation activities can cause substantial changes in hyporheic exchange (HE). This study explores the characteristics of HE induced by benthic burrows th...

Abstract Design storms are key components for planning drainage networks and flood risk management. Due to atmospheric processes, precipitation accumulations across multiple temporal intervals are often correlated and can combine to shape flood intensities. However, current design storm guidance ove...
