Shoreline Management In Chesapeake Bay, C. Scott Hardaway Jr., Robert J. Byrne

Reports

This document describes and illustrates specific, practical responses to shoreline management issues. We will begin with a look at the evolution of the Chesapeake Bay and its ongoing, long-term processes. We will proceed to a discussion of the daily, physical mechanisms that affect shoreline change and the topics professionals address in evaluating sites. We will then discuss strategies for managing shorelines, such as bulkheads, seawalls, revetments, groins, breakwaters, beach nourishment, and marsh fringes, as well as taking no action. Finally, we will give you a framework to apply these ideas in terms of the physical environment at the site and …

Zinc Speculation And Ligand Fluxes In Chesapeake Bay And Elizabeth River Pore Waters, Duncan Glover Byers

Chemistry & Biochemistry Theses & Dissertations

Presented here are the first data on the vertical concentrations, complexation, speciation, and fluxes of total dissolved zinc and zinc complexing ligands, and zinc speciation in sediment pore waters in the Chesapeake Bay and Elizabeth River, Virginia.

Sediment pore waters were collected in mid and southern Chesapeake Bay in November 1997 and in the Elizabeth River (Pinner's Point) in March, April, and July 1998. Flux experiments were conducted in Elizabeth River sediment cores in April and July 1998. [TDZn] and zinc complexation were determined using differential pulse anodic stripping voltammetry at a hanging mercury drop electrode (DPASV-HMDE).

[TDZn] in the …

Shoreline Management Plan With Habitat Enhancement For Town Of Saxis, Virginia, C. Scott Hardaway Jr., Donna A. Milligan, George R. Thomas, Rebecca C.H. Brindley, Lyle M. Varnell, Walter L. Priest, Sharon Dewing

Reports

The goal of the present study is to identify the best course of action to manage shoreline erosion in Saxis and to provide a detailed Shoreline Management Plan with Habitat Enhancement which can be presented to potential State and Federal funding agencies. While the Plan itself will not resolve the erosion conditions in Saxis, it will allow the Town to market its need and the method of resolution of this need, to agencies and leaders with the resources to implement the Plan’s suggested actions. The shoreline management plan will provide the necessary level of shoreline stabilization while minimizing adverse impacts …

A Two-Dimensional Analytic Tidal Model For A Narrow Estuary Of Arbitrary Lateral Depth Variation: The Intratidal Motion, Chunyan Li, Arnoldo Valle-Levinson

CCPO Publications

An innovative method is introduced to solve a two-dimensional, depth-averaged analytic model for narrow estuaries or tidal channels with arbitrary lateral depth variations. The solution is valid if the lateral variation of the amplitude of tidal elevation (\Delta a\) is small, i.e., \Delta a\ much less than a, where a is the amplitude of the tidal elevation. This assumption is supported by a 60-day observation of elevation in the James River Estuary using pressure sensors at both sides of a cross section of the estuary. The error introduced by the solution is of the order of \Delta a\/a, which has …

Sub-Lethal Effects Of Hypoxia/Hypercapnia On Callinectes Sapidus In The York River Estuary, Virginia, Sandra R. Hypes

Theses and Dissertations

This research examined effects of hypoxic environments on blue crabs, Callinectes sapidus in an estuarine environment. Hypoxic conditions were treated as a multiple stressor involving low dissolved oxygen (D.O.), increased carbon dioxide (hypercapnia), and low pH concurrently. The objectives were to: 1) identify hypoxiahypercapnia by monitoring D.O. and pH as an indicator of hypercapnia in shallow regions of the York River, 2) measure blue crab abundance, and 3) describe blue crab responses to hypoxiahypercapnia via field work at Taskinas Creek and lab measurements of respiration. Ambient D.O. and pH were positively correlated in the Taskinas Creek and York River sites …
