Laminar and turbulent dispersion of miscible fluids in porous media
… in a column of porous medium. The experimental breakthrough curve was used with this equation to find the longitudinal dispersion coefficient as a function of average pore velocity.

Effect of surfactants on the sorption and transport of Cu(II) in a sandy soil : batch, column experiments and modeling
… capable of describing the entire experimental breakthrough curve (BIC) in most instances

Chloride Salts Removal by non Planted Constructed Wetlands Receiving Synthetic Brines from Belle Plaine Potash Mining
… In the 4-day format operation, the chloride breakthrough curve was discovered in all treatment CW cells, excluding the control. Moreover, the curve stated at less than 6 hours (C/C0 > 0.05) and approximately reached the break point (C/C0 > 0.95) after passing 48 hours. Then the clay media was …

Studies of hydrophobic organic pollutant interactions with cyclodextrin: implication for groundwater remediation
… derived with the linear coefficient of 0.999. Breakthrough curves of single solute, TCE were obtained over a range of flow velocities (1-10 ml∙min-1) and HPCD concentrations (0, 20, and 50 g∙L-1). Relationships between the pore velocities and two-site non-equilibrium parameters obtained from …

LONGITUDINAL SOLUTE TRANSPORT IN OPEN-CHANNEL FLOW - A Numerical Simulation Study on Longitudinal Dispersion, Surface Storage Effects, Transverse Mixing, Uncertainties and Parameter-Transferring Problems
… model (ADM), but it cannot simulate the breakthrough curve (BTC) immediately after a large pool. Additionally, the calibration (parameterization) method is challenged by the non-identifiability which is common to all inverse modeling, and it seems TSM cannot be easily used as a predictive …

Solute dispersion in selected tropical soils
… and was used to trace fluid dispersion. Tritium breakthrough curves differed because of different dead-end porosities of these soils and were estimated to range from 4 to 30 per cent. Potassium, calcium, and phosphate showed trends in their breakthrough curves that were due to dead-end pores. …

Assessment of scaling and information requirements of the classical advection dispersion equation and a temporal-nonlocal advection dispersion equation at the MADE site, An
… test (SWIW) at the MADE Site with a skewed breakthrough curve (BTC). High resolution hydraulic conductivity and facies data were collected in the area of the SWIW test. This data was used to statistically generate a high resolution $K$ domain of the aquifer material and was spatially …

INVESTIGATIONS OF PREFERENTIAL AND MATRIX FLOW IN A MOLE DRAINED SOIL BLOCK
… mesopores. This result was supported by breakthrough curve analysis for the bulk of the soil although macropore flow was observed towards the mole drain. Flow rates observed from tracer movement varied throughout the soil regardless of depth. Chloride moved quickly towards the mole drain …

Use of Biochar to Produce Reclaimed Water for Irrigation Reuse Purposes
… negligible when compared to KOH-biochar. From breakthrough curves that were plotted for native and KOH-biochar for TOC removal from treated wastewater, It was observed that, even though KOH-biochar removal efficiency for TOC was better at the beginning, both native and KOH-biochar reached their …

Hydrothermal synthesis and characterization of zeolite from Malaysia’s natural kaolin for adsorption of sodium ion (NA+) from seawater
… Kinetic Model) and column adsorption analysis (Breakthrough curve model). The various parameter was applied to the batch experiment (Zeolite-A dosage, time, initial sodium ion concentration and volume) and column experiment (Zeolite-A dosage, initial sodium ion concentration and flow rate). For …

Water and nutrient transport dynamics during the irrigation of containerized nursery crops
… substrate-filled columns to characterize tracer breakthrough under saturated and unsaturated conditions. 3) Controlled-release fertilizer (CRF) was topdressed (surface-applied), incorporated (throughout substrate), dibbled (center of substrate) or not applied to fallow substrate, irrigated with …
