Pollutants such as industrial chemicals, agricultural runoff, untreated sewage frequently enter rivers via surface runoff or direct discharges. This study provides an overview key mechanisms governing contaminant transport in rivers, with special attention storage hyporheic processes. The process conceptualizes a ubiquitous reactive boundary between main channel (mobile zone) its surrounding slower-flow areas (immobile zone). Research from last five decades demonstrates crucial role zones influencing solute residence time, nutrient cycling, pollutant degradation. A review models highlights significant advancements, including like transient model (TSM) multirate mass (MRMT) model, which effectively capture complex zone dynamics time distributions. However, more widely used classical advection–dispersion equation (ADE) cannot exchange, limiting their application environments contributions. Despite these challenges remain accurately quantifying relative contributions degradation, especially smaller streams dominated by exchange. Future research should integrate detailed field observations advanced numerical address gaps improve predictions across diverse river systems.

ABSTRACT Climate change, population growth, urbanisation and water pollution will exacerbate the closely linked challenges of quantity quality. The River Spree in Berlin, Germany, experiences recurrent low flow conditions summer with seasonal reversals certain sections river. This reverse leads to transport treated wastewater upstream possibly introduction into Lake Müggelsee, which is located city centre important for drinking production via bank filtration Berlin. A better understanding contaminant dynamics required, but field data on are still lacking. In 2022 2023, we collected surface samples quantify major ions trace organic contaminants. Over a period nine months also measured specific electrical conductivity at six locations temporal resolution five minutes. During summer, increased sampling mouth wastewater‐impaired Erpe. proved be an indicative parameter periods. flow, observed concentrations wastewater‐derived contaminants, many correlated positively conductivity. Strong differences intensity between 2023 indicate that both precipitation discharge Müggelsee have strong influence flow. study demonstrates applicability easy‐to‐measure as proxy hydrological chemical

Abstract The influence of bioturbation induced by bottom‐dwelling macrozoobenthos on nitrogen dynamics in lotic stream sediments remains unclear. In this work, we advance the understanding faunal environments developing a fully‐coupled flow and multicomponent reactive transport model investigate sediment reworking burrow ventilation processes nitrogenous transformations. results indicate that significantly increase nitrate (NO 3 − ) influx, penetration depth, reaction rates streambed. Denitrification were observed up to three times higher beds with U‐shaped burrows compared flatbeds. ratio mound height water depth ( h / H 0 is dominant control determining relative importance modulating reactions. A power‐law scaling framework ultimately proposed predict NO removal efficiency based Damköhler number bioturbated streambeds.
