UMRR Starved Rock 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）下属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年起便负责水深测量数据（bathymetric data）的采集、处理与服务供给工作。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正式完成。
水生生态系统中的水深是描述河流物理特征的核心指标之一。
水深测量图（bathymetric map）可用于开展水生栖息地的空间清查，以及检测由泥沙沉积引发的河床及高程变化。
水深测量数据应用场景广泛，尤其可用于水位管理方案比选、航运影响模拟与水力条件建模，以及植被分布格局调查等各类环境评估工作。
本次提及的水深测量覆盖范围（footprint）数据库，可作为快速检索各LTRM监测池内对应水深测量覆盖范围采集日期的实用工具。
