In today’s digital age, Dam Owners and Engineers knowing the location of dam related impacts both upstream and downstream is critical. Unfortunately, the majority of impact data for DCR SWC’s 104 flood control dams are in paper or limited electronic format portraying impacts as a “screen shot in time.” In an effort to provide current […]
If performance data is provided to decision makers, it often comes from manufacturers. Much of this data is derived from reputable sources such as the New Jersey Department of Environment Protection program, the Washington Department of Ecology Technology Assessment Protocol – Ecology (TAPE) program or the International BMP Database but it is difficult for many […]
Routine quarterly inspections are integral to meeting Georgia Safe Dams Program (GSDP) requirements and maintaining the long-term health of the 30 dams owned and operated by the Gwinnett County Department of Water Resources’ (GCDWR). Since 2017, Hazen and GCDWR have worked together to regularly update and upgrade the inspection program to meet GCDWR’s evolving needs […]
Flooding in coastal areas can occur as a result of several factors, including low-lying areas, land subsidence causing adverse slopes in storm sewer pipes, high groundwater, inadequate hydraulic carrying capacity, and the age of the stormwater system, which may have been laid in the ground before current design standards were implemented. In recent years, another […]
Virginia Soil and Water Conservation Districts received funding for the installation of remote monitoring equipment. The current monitoring network consists of 64 installed units, 33 units waiting for installation. This presentation will discuss the various challenges faced when managing and using the data collected.
The City of Virginia Beach converted a man-made borrow pit, formerly referred to as Whitehurst Lake, into a Dredged Material Management Area (DMMA). The intent was to provide a long- term disposal site for dredging projects throughout the City of Virginia Beach. The DMMA has been used for the disposal of dredged material from various […]
As water managers and engineers, it’s important to understand our watersheds, the urban landscapes, and their response to extreme events like heavy precipitation and rising surface water levels. These events can impact property, municipal infrastructure, and water quality. Of the numerous tools at our disposal, there are many benefits to continuous water monitoring systems, including […]
The accessibility of authoritative and comprehensive geospatial data allows for tailored analyses over a wide range of subject areas and resolutions. One such application of GIS is a regional study of streams (and other measured waterbodies) to identify sections that would most or least benefit from restoration efforts. Criteria for the selection process can be […]
As water managers and engineers, it’s important to understand our watersheds, urban landscapes, and their response to extreme events like heavy precipitation and rising surface water levels. Of the numerous tools at our disposal, there are many benefits to a flood warning system, including knowing in time where flooding issues could occur, enabling reactive action, […]
In recent years, the management of urban drainage systems has become increasingly complex, especially in areas with mature infrastructure and stringent spatial constraints. Traditional methods of surveying and mapping, while effective, often come with significant drawbacks such as prolonged traffic disruptions, safety risks, and limitations in data accuracy and detail. This presentation proposes a transformative […]
The Virginia Lakes and Watershed Association is a volunteer organization and its mission is to provide education on water resources in Virginia.
