Longitudinal Profiles of the Bad (Mashkiiziibii) and Kakagon Rivers in the Bad River Estuary, Wisconsin, Derived from Sonar Surveys Conducted 2015-2022

Longitudinal profiles of water depths were collected by sonar equipment from the centerline of the Bad River (Mashkiiziibii) channel in 2015, 2016, 2021, and 2022 and from the Kakagon channel in 2021 and 2022. Long profile points from each collection were referenced to a common water surface datum and channel centerline, and assigned a longitudinal distance upstream from the river mouth, allowing for comparison between years and evaluation of channel bed aggradation and incision through time. The 2021 depth values were additionally converted into elevations referenced to the NAVD88 datum and integrated into the digital elevation model (DEM) representing post-flood land surface conditions that was used in the landform mapping, geomorphic change, and estuary inundation analyses.

本数据集包含2015、2016、2021与2022年通过声呐设备获取的巴德河（Mashkiiziibii）河道中心线水深纵剖面数据，以及2021、2022年获取的卡卡贡河道同类数据。所有单次采集得到的纵剖面测点均以统一水面基准面与河道中心线为参照基准，并被赋予相对于河口的上游纵向距离，由此可实现不同年份间的数据对比，同时可评估河道床体随时间推移的淤积与下切变化。此外，研究人员将2021年的水深数据转换为以北美垂直基准面1988（NAVD88）为参照的高程值，并将其整合至表征洪水后地表状态的数字高程模型（DEM）中，该模型已应用于地貌制图、地貌变化分析及河口淹没分析等研究工作。
