Sediment erosion is a natural process influenced by geology, soil characteristics, terrestrial habitat cover (land cover), topography, and climate.

Some generalizations can be made about erosion, sediment yield (mass per unit area per unit time), and land use in the bay watershed (Chapters 2 and 3).

The primary objective of this report, therefore, is to provide a review of the literature on the sources, transport, and delivery of sediment in Chesapeake Bay and its watershed with discussion of potential implications for various management alternatives.

The Sediment Workgroup, has completed a document entitled “A Summary Report of Sediment Processes in the Chesapeake Bay and its Watershed”. The primary objective of the report is to provide a comprehensive review and analysis of the literature on the sources, transport, and delivery of sediment in Chesapeake Bay and its watershed with discussion of the implications for management.

predominant sediment transport processes in the Bay watershed and the Bay tidal waters and the subsequent effect of suspended sediment on the SAV community.

However, this refined water quality model is not expected to be completed until the summer of (for testing runs only). Sea level rise also contributes to tidal erosion. Sea level in the Chesapeake Bay has risen approximately feet over the past years, and is expected to continue to rise in the next century.

Recent estimates suggest that this rate may increase to as much as feet in the next years (Leatherman et al. Physically and chemically, sediment is a pollutant of concern in many waterbodies. In the Chesapeake Bay, sediment is having an adverse effect on the living resources and habitat of the Chesapeake.

The mapping of WSM variables into WQSTM variables is detailed. The report concludes with a statistical summary of model results. At present, the model computations of total nitrogen are in excess of observations.

Scientists estimate that most of the sediment that flows into the Chesapeake Bay comes from watershed sources. In the Bay watershed, river basins with the highest percentage of agricultural lands yield the highest amount of sediment each year. Basins with the highest percentage of forest cover, on the other hand.

Chesapeake Bay states can use qualifying shoreline management practices as part of an overall watershed strategy to meet nutrient and sediment load reduction.

The Chesapeake Bay Agreement contained provisions related to the identification and correction of sediment problems, including those associated with the Bay watershed that ultimately affect the Bay’s condition.

In addition to setting these limits, known as Total Maximum Daily Loads (TMDLs), EPA required the Bay watershed.

U.S. Geological Survey suspended-sediment data from to from selected stream-gaging stations draining the nontidal parts of the Chesapeake Bay Watershed were summarized to identify areas in the Watershed with high suspended-sediment loads, yields, and concentrations.

The suspended-sediment load data were separated into two periods. and. The process begins with BMP Expert Panels that evaluate existing research and make initial recommendations on removal rates. These, in turn, are reviewed by the Urban Stormwater Workgroup (USWG), the Watershed Technical Workgroup (WTWG) and the WQGIT to ensure they are accurate and consistent with the CBWM framework.

The report, “A Summary Report of Sediment Processes in Chesapeake Bay and Watershed,” is expected to be completed soon, and will be available on the Bay Program’s web site, The USGS worked with these investigators to prepare a comprehensive review of sediment processes in the Bay and its watershed (Langland and Cronin, ).

The current chapter, along with the chapter by Willard on the longterm water-quality changes in the Bay, summarizes the highlights of these studies.

The Chesapeake Bay (Figure S-1) is North America’s largest and most biologically diverse estuary, as well as an important commercial and recreational resource.

However, excessive amounts of nitrogen, phosphorus, and sediment from human activities and land development (e.g., agriculture, urban and suburban runoff. communication and outreach throughout the Chesapeake Bay watershed and beyond.

One result highlighted at the meeting was the recent publication of A Summary Report of Sediment Processes in Chesapeake Bay and Watershed (USGS Water-Resources Investigations Report ), edited by USGS scientists Michael Langland and Thomas Cronin (to download a copy of the new publication, visit the MGS List of Publications Web page).

In the Chesapeake Bay, sediment and associated nutrients are having an adverse effect on the living resources and habitat of the Chesapeake Bay and its watershed.

The immediate need was to offer local planners within the Chesapeake Bay Watershed with a tool to provide input into the TMDL Watershed Implementation Plan development process.

With continued funding from the U.S. EPA, the functionality of CAST has been expanded to serve multiple needs for environmental planning in the Chesapeake Bay Watershed.

Figure Distribution of sediment yields in the Chesapeake Bay watershed, – (from Gellis, Banks, and others, ).USGS analysis of historical sediment data found the highest yields in the Piedmont, with the lowest yields in the Coastal Plain, indicating that management actions to reduce sediment to tidal fresh areas should be targeted in the Piedmont.

Sediment sources in the Chesapeake Bay watershed include agricultural areas, forests, roads, urban areas, construction sites, gullies and ditches, mines, and streambeds and banks. Management strategies to reduce sediment inputs differ depending on whether the sediment is eroded from upland areas or from streambeds and banks.

Therefore, it is. Phase 3 of Pennsylvania's Chesapeake Bay Watershed Implementation Plan (WIP3) The Pennsylvania Department of Environmental Protection (DEP) invites comments from residents, communities, farmers, and local government leaders on a draft plan to improve water quality in streams and rivers by removing nitrogen, phosphorus, and sediment pollution in the Chesapeake Bay.

Sediment in the Bay Although sediment erosion and sediment deposition occur naturally, human activities can greatly hasten the rates of both processes. While some sediment enters through oceanic input and shore erosion, the bulk of the sediment washing into the Bay comes from stream channel.

Chesapeake Bay” workshop was designed to assemble the most current scientific information on the role of wetlands in reducing loads of nitrogen, phosphorus, and sediment in overland flow. The Chesapeake Bay Program’s (CBP) Watershed Model estimates the effects of various. Total Maximum Daily Load (TMDL) and Watershed Implementation Plans (WIPs).

The Environmental Protection Agency (EPA) is providing the enclosed draft sediment allocations, expressed as total suspended solids (TSS), as one ofthe remaining steps in the path to developing the draft Chesapeake Bay .The Chesapeake Bay Program has developed water-quality criteria and is requiring all jurisdictions in the bay watershed to develop and implement watershed implementation plans (WIPs) that would reduce nutrient and sediment loads entering the Bay to levels prescribed by the TMDL by Chesapeake Bay Watershed Agreement.
