The RBCA Tier 2 Analyzer utilizes an innovative analytical flow solution for fast and easy modeling of complex groundwater flow systems it provides a rigorous treatment of the many complex reactions and processes involved with the biodegradation of contaminated groundwater. These two features make it the ideal software package for applications including:
Expert System Advantages
The RBCA Tier 2 Analyzer addresses both of these problems by providing an on-line expert system with published parameter values and references for many different soil conditions and common chemicals of concern. In addition, the RBCA Tier 2 Analyzer uses a powerful and innovative solution method that allows you to solve complex models involving biodegradation of multiple chemical species in a matter of minutes! Try that with RT3D and you could be waiting for hours. Imagine the time you could save on just your first project alone!!
The Flow Model
The Plume Generator
The Transport Model
The RBCA Tier 2 Analyzer is also the first commercially-available model to incorporate the physics of multi-site, rate-limited partitioning of chemical mass between soil and groundwater. Rate-limited desorption (RLD) of organic contaminants is the most significant limitation of pump-and-treat groundwater remediation systems. The effects of RLD are seen in the extended periods of low mass removal rates which were not predicted by models using local equilibrium sorption/desorption assumptions. Now, for the first time, you have a modeling software package that allows you to account for and predict the effects of RLD desorption on groundwater extraction systems.
The RBCA Tier 2 Analyzer uses the Eulerian-Lagrangian solution technique to solve the governing equation of solute transport. This technique utilizes the Method of Characteristics (MOC) for solving the advective part of the equation, and it uses the Alternating Direction Implicit (ADI) method for solving the dispersive part of the equation. This combination of solution techniques ensures the best results in the shortest time by avoiding the numerical dispersion and small time steps often encountered by other numerical approaches.
