Tools for Regional Sediment Management

Abstract

This Coastal and Hydraulic Engineering Technical Note (CHETN) describes tools that have been adapted to assist with Regional Sediment Management (RSM) activities at the U.S. Army Engineer Districts, Mobile and New York. Geographic Information Systems (GIS) designed for RSM in the Mobile District, and numerical models that have been adapted for regional studies within the New York District are discussed. Rosati et al. (2001) contains background information on RSM goals and procedures. Some of this information is briefly reproduced for continuity herein. RSM refers to the effective utilization of littoral, estuarine, and riverine sediment resources in an environmentally effective and economical manner. RSM strives to maintain or enhance the natural exchange of sediment within the boundaries of the physical system. RSM changes the focus of engineering activities within the coastal, estuarine, and riverine systems from the local, or project-specific scale, to a broader scale that is defined by the natural sediment processes and may include the entire watershed. Implementation of RSM recognizes that the physical system and embedded ecosystems are modified and respond beyond the formal dimensions and time frames of individual projects. The larger spatial and longer temporal perspectives of RSM, as well as the broad range of disciplines with a stake in RSM projects, require partnerships with and co-leadership of RSM initiatives by the stakeholders. Decisions concerning the timing and scope of projects that move or utilize sediment must be made within an understanding of the regional system. The Corps' National RSM Demonstration Program began in the Mobile District in October 1999. Separately, the grassroots movement for RSM grew with Corps Districts pursuing RSM initiatives with State and local partnerships.
