Delaware river watershed facts

Delaware River Watershed Facts

  • 16 million people (about 5% of the U.S. population) rely on the waters of the basin

  • Drains 13,539 mi² , or 0.4 of 1% of the continental U.S. land area

  • 4 states, 42 counties, 838 municipalities

  • 25 Congressional Districts

Drbc issues

DRBC Issues

  • Water Flows Highly Managed due to 1954 Supreme Court Decree

    • NYC allowed to divert up to 800 mgd out of basin

    • Changing Priorities – Water supply, fisheries, flood mitigation

  • Pollution

    • Major clean up ,but now toxics and emergent contaminants

    • Special Protection Waters

  • Flood of Record – 1955

  • Drought of Record – 1960’s

  • Three Floods – 2004 – 2006


Value of nws to drbc

Value of NWS to DRBC

  • Basic data and AHPS

    • Flood potential, flow augmentation, river monitoring events

  • Always Improving Flood Warning System

  • Reservoir Flood Model – NWS, USGS and USACE

  • Strong Partner and Supporter


Future issues

Future Issues

  • Climate Change

    • Sea Level Rise

    • Increased Storm Intensity

    • Increased Drought Probability

    • Increased Uncertainty

  • Impacts to Sensitive Headwaters

    • Natural Gas Well Drilling

    • Loss of Forest; increased Impervious cover

  • Changing Population Distribution/Water Demand

Sea Level Rise

Global Sea Level Rise

Regional Changes

gravity, ocean currents and ocean density

subsidence

Global + Regional

0.45 + 0.27 = 0.72m

(2.3 ft)

1.4 + 0.27 = 1.67m

(5.5. ft)

Model

0.5 meter rise

1.0 meter rise

1.5 meter rise


Changes in snowpack and timing of snowmelt

Changes in Snowpack and Timing of Snowmelt

  • There will be less snow in the winter; this affects water supply for many who depend on the melting of snowpack as a water source. The timing of snowmelt may also change, prompting water resource managers to change how water supply reservoirs are managed.

Water Intakes at Risk from Drought and Sea Level Rise:

location of the salt line at high tide during drought

  • Power

    • Exelon Delaware Generating Station

    • Exelon Richmond Generating Station

    • Philadelphia Gas Works Richmond

  • Industrial

    • Koch Material Co.

    • NGC Industries

    • Rohm and Haas Philadelphia

    • MacAndrew and Forbes Co.

    • Pennwalt Corporation

    • Sunoco

  • Public Supply

    • Torresdale Water Intake (provides

    • almost 60% of Philadelphia’s water supply)

    • New Jersey American Water Co. Tri-County Water Treatment Plant


Questions and needs

Questions and Needs

  • Will there be adequate water supply?

  • Will we have enough water to push salinity down?

  • Do we need more structural storage for flood mitigation and water supply?

  • How will better stormwater control, LID, riparian buffers improve the system?

  • Need for basin-wide model to test scenarios

  • Probability factors, Range of conditions, Down-scaling


More needs

More Needs

  • Continued improvements to AHPS and nundation mapping

  • A more stable server for AHPS

  • Improved rainfall runoff model

  • Storm surge forecasting for tidal river


Thank you

Thank You!!

  • NWS is one of DRBC’s strongest Partners

  • The management of the basin is dependent on NWS data, models and predictions
