  • Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1971-06)
    The feasibility of using geophysical techniques in determining the amount of overburden and the nature of the subsurface along a proposed highway was tested in the Piedmont area of Delaware. The area is underlain by ...
  • Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1984-07)
    Earthquakes in Delaware and surrounding areas have been well documented historically since about the early 1700’s and since 1972 by instrumental records. Most of the Delaware events have occurred in the Wilmington area ...
  • Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1970-07)
    Information on ground-water quality in Delaware has become critical for three reasons: (1) increased water demand, (2) need for a better understanding of ground-water flow patterns, (3) need for a "base" against which ...

    The information contained in this Guidebook was compiled on the occasion of the Annual Meeting of the Association of American State Geologists held in Delaware in June 1977. The Delaware Geological Survey is pleased to ...
  • Woodruff, K.D.; Miller, J.C.; Jordan, R.R.; Spoljaric, N.; Pickett, T.E. (Newark, DE: Delaware Geological Survey, University of Delaware, 1972-05)
    The results of an intensive ground-water study on University of Delaware lands in the Newark area revealed additional sources of available ground water. Geophysical techniques, air-photo interpretation, studies of existing ...
  • Woodruff, K.D.; Plank, M.O.; Werkheiser, W.H. (Newark, DE: Delaware Geological Survey, University of Delaware, 1995)
    The effect of rapid growth in the Hockessin and Pleasant Hill areas in northern Delaware has caused concern about possible declines in ground-water recharge to the underlying Cockeysville Formation. The Cockeysville is a ...

  • Spoljaric, N.; Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1970-08)
    Columbia sediments in the Middletown-Odessa area are composed of boulders, gravels, sands, silts and clays. These sediments are exposed in four gravel pits where their structures and textures were studied. Subsurface geology ...
  • Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1998-02)
    Because of its "renewability" water is unique among earth resources that sustain and enhance life. No other mineral resource that we extract on a long-term and continuous basis can be counted on for at least some degree ...
  • Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1967-04)
    This report deals with fluctuations in nine observation wells during the period 1960 - 1966. These wells are part of a state-wide ground-water monitoring network and are located in areas of little or no pumping. Eight of ...
  • Jordan, R.R.; Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1982-05)
    Numerical indicators, or indices, are widely used to measure the status of complex relationships. As such, indices have become accepted by researchers and the public in such disparate fields as economics, air quality, and ...
  • Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1969-08)
    The location of the fresh-salt-water-boundary in the deeper aquifers of Delaware is related mainly to head values. Near coastal areas, dynamic conditions may prevail that affect the interface position within shallow aquifers ...
  • Jordan, R.R.; Pickett, T.E.; Woodruff, K.D. (Newark, DE: Delaware Geological Survey, University of Delaware, 1972-04)
    Earthquakes are an unfamiliar phenomenon in Delaware. Because of the great public and scientific interest in the seismic events that have recently affected northern Delaware, this Open File Report has been prepared to ...
  • Woodruff, K.D.; Jordan, R.R.; Pickett, T.E. (Newark, DE: Delaware Geological Survey, University of Delaware, 1973-04)
    This report has been prepared to fill an immediate need for information on the earthquake that affected northern Delaware on February 28, 1973. Public interest in seismic events has grown in the past two years because of ...
