Colville River Delta Sea Ice Model and Output Data Files

In this study, we used a 1D Delft3D-FLOW model to simulate the temporal development of the Colville River Delta, AK during the most active Arctic seasons. Simulations focused on the deltaic clinoform (i.e., the cross-sectional view of a delta) and used a floating barge structure to mimic the effects of sea ice on surface waters. Delft3D simulations were coupled with modules written in MATLAB and outputs were process in MATLAB.
The dataset includes an example model run file (Delft3D-FLOW and MATLAB) and output of results from simulations used to assess Arctic delta development under sea ice.  
Files include:

Example Delft3D-FLOW model setup file, MATLAB run script, and ice files for a 1500-year simulation.
Processed MATLAB structures and metadata for model results

Scenario A
Scenario B

本研究采用一维（1D）Delft3D-FLOW模型，模拟了北极活动最旺盛季节期间，美国阿拉斯加州（AK）科尔维尔河三角洲的时间演化过程。模拟工作聚焦于三角洲斜层（deltaic clinoform，即三角洲的横截面形态），并通过浮动驳船结构模拟海冰对表层水体的影响。Delft3D模拟与MATLAB编写的模块实现耦合，模型输出均通过MATLAB完成处理。

本数据集包含示例模型运行文件（Delft3D-FLOW与MATLAB相关文件），以及用于评估海冰作用下北极三角洲演化的模拟结果输出。所涵盖文件包括：
用于1500年模拟的示例Delft3D-FLOW模型配置文件、MATLAB运行脚本及海冰文件。
模型结果的MATLAB处理结构体与元数据。
