Abstract Investigations of coupled multiphysics processes in rivers and hyporheic zones have extensively used numerical models. Most existing models use a sequential, one‐way coupling between the surface subsurface domains. Such potentially introduces error. To overcome this, fully model, hyporheicFoam , was developed using open‐source computational platform OpenFOAM. It captures flow multicomponent reactive transport within both domains across their interface. The two is implemented by...
Hyporheic zones (HZs)─zones of groundwater-surface water mixing─are hotspots for dissolved organic matter (DOM) and nutrient cycling that can disproportionately impact aquatic ecosystem functions. However, the mechanisms affecting DOM metabolism through space time in HZs remain poorly understood. To resolve this gap, we investigate a recently proposed theory describing trade-offs between carbon (C) nitrogen (N) limitations as key regulator HZ metabolism. We propose throughout extent HZ,...
Urban estuaries are subject to frequent stressors, including nutrient loading and hydrological flashiness, which worsen water quality disrupt ecosystem function. Land use changes associated with urbanization, as well atypical precipitation conditions can exacerbate stress on estuarine health. However, generalizable patterns parameters involved in responses urbanization extreme events remain unknown. We investigated physicochemical factors urban land-use characteristics that associate...
Urbanization is a leading cause of global biodiversity loss, but its impact on soil microorganisms and biogeochemistry remains uncertain. To address this gap, we investigate urban microbiome composition using metagenomic sequences from the Global Urban Soil Environment Ecology Network (GLUSEEN). We seek to reveal (1) changes in taxonomic functional potential (2) ubiquitous (core) taxa metabolisms across microbiome. hypothesize that diversity are correlated due unique selective pressures...
