Description :
The dated sediments were collected from the banks of tie channels along the Lower Mississippi River, the Fly River in Papua New Guinea, and Birch Creek along the Yukon River in Alaska. Tie channels connect the oxbow lakes to the main stem river and allow the exchange of water and suspended sediment between the two. In all 3 river systems, OSL dating allowed the determination of vertical accretion rates, tie channel advancement rates, and oxbow lake ages.
