Abstract In this study, a sand-tank model as physical analog of real-world aquifer is presented for groundwater instruction. The sand tank used introducing flow nets and quantifying flow, modeling calibration via spreadsheet, dye-transport modeling. Students learn from the through interaction visualization, by collecting interpreting data. This integrates theories lectures into laboratories, en...

An overview of the problem of contaminant transport in heterogeneous geological media is given. The main physical principles causing anomalous transport regimes in fractured rock media are identified. Five theoretical models taking into account specific features of geologic media and manifesting non-classical transport behavior are presented and compared with data from field observations. INTRO...

Some facilities, such as Los Alamos National Laboratory, have contaminants at widely scattered locations Modeling of vadose zone hydrology is required to address a variety within a landscape of complex topography. This type of of applied problems in general and risk assessments associated with spatial distribution of contamination poses a particularly contaminants in particular. Risk assessment...

This work presents an approach to solve inverse problems in the application of water quality management in reservoir systems. One such application is contaminant cleanup, which is challenging because tasks such as inferring the contaminant location and its distribution require large computational efforts and data storage requirements. In addition, real systems contain uncertain parameters such ...
