WebOct 24, 2024 · In contrast to our reference model, many aquifer- or catchment-scale models on nitrate transport neglect almost all details of the reactive system and describe denitrification as a simple first-order decay process that may depend on the organic carbon content of the soil (e.g., Almasri & Kaluarachchi, 2007; Liu et al., 2024; Zhang et al., 2024 ... WebJan 17, 2024 · Reactive transport models (RTMs) have traditionally focused on transport and multi-component biogeochemical reactions mostly in groundwater systems with limited interactions with climate and other surficial conditions (Steefel et al., 2015; Li et al., 2024b). Some integration crossing disciplinary boundaries did occur in recent years.
