Simulating Material Movement through the Lower Altamah Sing a 1-d Box Model

1-D optimum-boundary b were used to simulate the movement o pollutants or other conservatively mixing c through the Altamaha River estuary. Tr introduced into the models as point sources locations within the estuary and as a non-po the entire system. In each case, models w four different river flow rates and were used both the movement of tracer within the estu rate of removal. When tracer was introduced tide, it moved rapidly (from 1-2 d, depending to the head of the mixing zone 30 km do Tracer released anywhere in the estuary, farther downstream at 2 km, moved toward km upstream of the mouth, where it remaine as overall removal continued.

When released tide, maximum exposure is experienced at Simulations of the type presented here are us evaluating the conservative movements of and non-point-source constituents in the estu
