|CSDMS meeting abstract=The formation of the branching channel network is controlled mainly by water discharge and the boundary shape of receiving basin. The understanding of channel morphology is important because it controls the sediment diversion in a river delta, and determines the sustainability of coastal zones. Numerical models of river deltas have improved remarkably over the past two decades. However, the long-term (millennial scale) simulation of real delta systems remains rare. Here, we attempt to reconstruct the Lafourche Delta channel network, active 1600-600 years before present, with a simple numerical model (Moving Boundary Model for Distributary Channel Networks MB_DCN). Runs with 10 basin boundary shapes and 6 river discharge rate scenarios using the Moving Boundary Model for Distributary Channel Networks (MB_DCN) show that each scenario produced distinguishing channel characteristics including a complex channel network, diverse progradation rates and channel numbers, and number of bifurcations. For the appropriate basin shapes, reasonable water discharges and common sediment transport parameters, MB_DCN produces a channel network that resembles the Lafourche Delta channel network morphology and progradation rates. Our preliminary results suggest that the basin boundary shape and water discharge are the most important control of the distributary channel network in terms of channel geometry and progradation rates.

Modeling sea ice motion using various artificial intelligence approaches

The movement of sea ice is influenced by a number of factors, from winds to ocean currents. As climate change continues to occur rapidly, understanding sea ice drift in the Arctic is a key parameter to understanding the effects of rising temperatures in the region. Recent literature has shown that the Arctic and the Antarctic are most affected by global warming, which raises questions regarding climate justice, as most of the carbon emissions causing anthropogenic climate change are produced in other regions. To analyze this impact, we employ artificial intelligence to predict sea ice drift velocity based on external features. Machine learning is the process of computers gaining insights by seeing and correlating large quantities of data. Using external parameters, including wind speed, and drift velocity ground truth as the inputs of the model, we train multiple different architectures and compare the results. Particularly, we experiment with a convolutional neural network (CNN), a random forest (RF), and a support vector machine (SVM). We also experiment with various model specifications. This research leads to a greater understanding of the Arctic’s response to climate change.
