Two-Zone Transient Storage Modeling Using Temperature And Solute Data With Multi-Objective Calibration: 2. Temperature And Solute, Bethany T. Neilson, David King Stevens, S. C. Chapra, Christina J. Bandaragoda
Civil and Environmental Engineering Faculty Publications
This paper presents the multiobjective calibration results for temperature and solutefrom a two‐zone temperature and solute (TZTS) model which separates transient storageinto surface (STS) and subsurface (HTS) transient storage components. This modelcontains terms associated with surface heat fluxes in the main channel (MC) and STS, heatand mass exchange between the STS and MC, heat and mass exchange between the HTSand MC, and heat exchange due to bed and deeper ground conduction. To estimate theadditional parameters associated with a multiple‐zone model, a data collection effort wasconducted to provide temperature time series and solute tracer curves representingthe movement of heat and/or solute …

This paper presents the formulation and calibration of the temperature portion of a two-zone temperature and solute (TZTS) model which separates transient storage into surface (STS) and subsurface transient storage (HTS) zones. The inclusion of temperature required the TZTS model formulation to differ somewhat from past transient storage models in order to accommodate terms associated with heat transfer. These include surface heat fluxes in the main channel (MC) and STS, heat and mass exchange between the STS and MC, heat and mass exchange between the HTS and MC, and heat exchange due to bed and deeper ground conduction. To estimate …
Groundwater Stress And Vulnerability In Rural Coastal Aquifers Of The Kalpitiya Peninsula, Sri Lanka, D. Jayasekera, Jagath J. Kaluarachchi, K. Villholth
Groundwater Stress And Vulnerability In Rural Coastal Aquifers Of The Kalpitiya Peninsula, Sri Lanka, D. Jayasekera, Jagath J. Kaluarachchi, K. Villholth
Civil and Environmental Engineering Faculty Publications
Rural coastal aquifers are undergoing rapid changes due to increasing population, high water demand with expanding agricultural and domestic uses, and seawater intrusion due to unmanaged water pumping. The combined impact of these activities is the deterioration of groundwater quality, public health concerns, and unsustainable water demands. The Kalpitiya peninsula located northwest of Sri Lanka is one area undergoing such changes. This land area is limited and surrounded almost completely by sea and lagoon. This study consists of groundwater sampling and analysis, and vulnerability assessment using the DRASTIC method. The results reveal that the peninsula is experiencing multiple threats due …
