UMRR Pool 9 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）下辖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）单元，自1989年起便负责水深地形数据（bathymetric data）的采集、处理与数据服务工作。2010年，针对密西西比河上游流域（Upper Mississippi River System, UMRS）的系统性数据采集工作圆满完成。水生生态系统中的水深是描述河流物理特性的核心指标。水深地形图（bathymetric maps）可用于开展水生栖息地的空间清查，以及识别因沉积作用导致的河床与高程变化。水深地形数据应用场景广泛，尤其可用于水位管理方案比选研究、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。水深地形覆盖数据集（bathymetry "footprint"）作为一款数据库工具，可用于快速检索各LTRM监测池内对应水深地形覆盖范围的采集日期。
