UMRR Pool 6 Bathymetry Footprint

The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element has overseen the collection, processing, and serving of bathymetric data since 1989. A systemic data collection for the Upper Mississippi River System (UMRS) was completed in 2010. Water depth in aquatic systems is important for describing the physical characteristics of a river. Bathymetric maps are used for conducting spatial inventories of the aquatic habitat and detecting bed and elevation changes due to sedimentation. Bathymetric data is widely used, specifically for studies of water level management alternatives, modeling navigation impacts and hydraulic conditions, and environmental assessments such as vegetation distribution patterns. The bathymetry "footprint" is a database that can be used as a tool to provide a quick search of collection dates corresponding to bathymetric coverages within each LTRM pool.

美国陆军工程兵团（U.S. Army Corps of Engineers）下设的密西西比河上游修复（Upper Mississippi River Restoration, UMRR）项目长期资源监测（Long Term Resource Monitoring, LTRM）工作单元，自1989年起便负责水深测量数据（bathymetric data）的采集、处理与服务供给。2010年，针对密西西比河上游水系（Upper Mississippi River System, UMRS）的系统性数据采集工作全面完成。水生生态系统中的水深状况是描述河流物理特征的核心参数。水深测量图（bathymetric map）可用于开展水生栖息地的空间清查，以及监测因沉积作用引发的河床形态与高程变化。水深测量数据应用场景广泛，具体涵盖水位管理方案研究、航行影响与水力条件模拟，以及植被分布格局等环境评估工作。“水深测量覆盖范围（bathymetry "footprint"）”作为一款数据库，可作为检索工具，快速查询每个LTRM监测池段内对应水深测量覆盖范围的采集日期。
