Determination of Minimal Instream Flow for Recreational Use Recreational canoeists established a network of gages in the 1970’s that reflect stream levels on Virginia’s rivers. This network of gages depicts at what level canoeing would become impracticable. As such, this is a potential measure of minimal instream flow requirements for recreational boating. This project uses the established network of gages and GPS technology to tie them to elevation benchmarks in order to relate the depicted stream levels to USGS stream gage data.
Development of a Draft Woody Depressional Wetland HGM Model for the Coastal Plain of Virginia This project takes the preliminary information developed in completion of the Development of a Forested Depressional Wetland HGM Model project and expands it to a Draft Woody Depressional Wetland HGM Model. The project expands the preliminary reference set from 8 sites to approximately 24 sites and coordinates the model development with similar efforts in Maryland and Delaware.
Development of HGM Models for Wetlands Management in Virginia This project initiated the development of HGM models in Virginia by 1) a planning exercise to identify and prioritize the needs for HGM model development in Virginia; 2) an initial effort to develop a Hardwood Mineral Flat model; 3) initial data collection on potential reference sites for other models; 4) a program to integrate remote sensing into HGM based wetland assessments; and 5) a protocol program to validate regional HGM models.
Draft Woody Depression Wetland HGM Model for the Coastal Plain of Virginia The Hydrogeomorphic (HGM) method for modeling and assessing wetlands is an emerging standard for many federal and state agencies. Implementation of this approach in Virginia is currently hampered by a lack of appropriate models. This project developed a draft Woody
Depressional Wetland HGM model for the coastal plain of the Commonwealth of Virginia.
Ecological Characterization of Stormwater Detention Ponds in Virginia's Coastal Plain The Ecological Characterization of Stormwater Detention Ponds in Virginia’s
Coastal Plain project has two main objectives: 1) to develop a database of existing stormwater ponds, both wet and dry, and 2) to characterize these ponds as to their design and their ability to perform the wetland functions of habitat, sediment stabilization and
water quality. Underlying objectives of this project included 1) the selection of a database application that can be utilized on the Internet and an evaluation tool for these specific wetland functions, 2) perform the field assessments, and 3) display the data
through an interactive web page.
Initiating Development of a Forested Headwater Wetland HGM Model for Wetlands Management in Virginia The Forested Headwater Wetland Subclass is unique in that it is partially defined in law by the average current flow (or lack thereof) continued in the associated stream. This project initiates the development of an HGM model for the Forested Headwater Wetland subclass by determining the extent of these wetlands systems as related to annual average stream flow. The final report will include development of a preliminary definition of Forested Headwater Wetlands for HGM model development and preliminary data collection of potential HGM variables.
Intermediate Development of a Forested Headwater Wetland HGM Model for Wetlands Management in Virginia The Forested Headwater Wetland Subclass is unique in that it is partially defined in law by the average current flow (or lack thereof) in the associated stream. This project continues the development of an HGM model for the Forested Headwater Wetland subclass by determining the extent of these wetlands systems as related to annual average stream flow. The final report will include development of a preliminary definition of Forested Headwater Wetlands for HGM model development and preliminary data collection of potential HGM variables.
Rappahannock County Riparian Buffer Study Riparian buffers are important zones for maintaining water quality and providing critical habitat. Rappahannock County has a rural landscape that presents the opportunity to record baseline conditions of riparian buffers. This study involved analyzing a small drainage area in the Upper Thornton River watershed to offer guidance on targeting riparian buffer restoration. Methods included using aerial imagery and GIS to delineate land uses and buffer cover in 100 ft. buffers around streams. Results indicate that in the study area 51% of the riparian lands potentially need some restoration and several recommendations for riparian buffer restoration were made in the final report.Final Report: http://ccrm.vims.edu/projreps/final_report_std.pdf

Coastal Maritime Forests in Virginia - Delineation and Distribution This project delineates coastal maritime forests using remote sensing techniques. Fieldwork conducted by the Department of Forestry validates the delineation. A website will be generated to display mapped forest cover and report the distribution of coastal maritime forest habitat in Virginia on a county by county basis.
Maritime Forest Project The purpose of this project were to use remote sensing techniques to delineate existing coastal maritime forests, as well as compute, on a county-by-county basis, the amount of maritime forest cover present in each coastal locality, and the extent of maritime forests located within conservation lands.
Tidal Wetlands Assessment - York River Assessment This study provides baseline data on the extent and condition of 2,188 tidal wetlands within the York River Watershed. These data provide valuable information in identifying wetland restoration opportunities, evaluating appropriate mitigation ratios, and determining cumulative impacts within a watershed.
Tidal Wetlands Multi-Level Assessment This includes reports, datasets and ArcIMS projects for Level I and II protocols within the Indian River, DE; Nanticoke River, MD, and York River, VA.
Wetlands Mitigation Targeting Tool This tool uses GIS to target sites in the landscape suitable for wetland creation. It has application for wetland restoration or mitigation projects. The tool outputs selected sites based on five suitability parameters: presence of hydric soils, presence of hydrology, adjacency to existing wetlands, existing landuse and the opportunity for landscape conversion, and proximity to designated conservation areas.
An Introduction to the Role of Riparian Buffers in Improving Environmental Quality Functions and Values Curriculum for a multi-day intensive course was prepared for a specific target audience of natural resource managers and professional staff. This grant supported the development of an interdisciplinary curriculum for the first day of the course series to be sponsored jointly by CCRM and the Chesapeake Bay National Estuarine Research Reserve (CBNERR). This course series will provide scientific background for existing regulations as well as training and assistance for effective enforcement, improved compliance and more effective communication with the regulated public about coastal riparian buffers and the Chesapeake Bay Preservation Act.
