Using Environmental Tracers in Modeling Flow in a Complex Shallow Aquifer System

摘要: Using environmental tracers in groundwater dating partly relies on the assumption that age distribution can be described analytically. To investigate applicability of complex multiaquifer systems, a methodology for simulating well specific was developed. model and particle tracking we modeled distributions at screen locations. By enveloping estimated recharge concentrations, tracer breakthroughs were simulated screens. Simulated are irregular shapes sizes without being similar to assumed used analytical approach. The shape some extent depends sampling size whether system is transient or steady state, but largely driven by heterogeneity topographical variations as well. Analytically derived ages depende...
