Features and Capabilities of Transport Pathways

In this set of topics the computational features of the primary contaminant transport component, the transport pathway Physical components or compartments through which contaminant species can move and/or be stored, such as aquifers, lakes, sediments, surface soil and the atmosphere. GoldSim provides four different elements for simulating pathways., are outlined. This will provide an indication of the kinds of processes that can be simulated by GoldSim.

GoldSim transport pathways represent physical components through which contaminant species The chemical (or non-chemical, such as bacterial or viral) constituents that are stored and transported through an environmental system in a contaminant transport model. In GoldSim, the Species element defines all of the contaminant species being simulated (and their properties). can move (and/or be stored) such as aquifers, lakes, sediments, surface soil compartments, and the atmosphere. In order to represent the wide variety of transport pathways that you may wish to simulate, GoldSim provides five different kinds of pathway elements:

• Cell pathways
• Aquifer pathways
• Pipe pathways
• External pathways
• Network pathways

These pathways can be used interchangeably within a model. Each of these four pathway elements is discussed briefly in the topics below.
