Basin-scale relations via conditioning
B.M. Troutman, M.R. Karlinger, D.P. Guertin
1989, Stochastic Hydrology and Hydraulics (3) 111-133
A rainfall-runoff model is used in conjunction with a probabilistic description of the input to this model to obtain simple regression-like relations for basin runoff in terms of basin and storm characteristics. These relations, similar to those sought in regionalization studies, are computed by evaluating the conditional distribution of model...
A multiple testing approach for hazard evaluation of complex mixtures in the aquatic environment: the use of diesel oil as a model
B. Thomas Johnson
1989, Environmental Pollution (58) 221-235
Traditional single species toxicity tests and multiple component laboratory-scaled microcosm assays were combined to assess the toxicological hazard of diesel oil, a model complex mixture, to a model aquatic environment. The immediate impact of diesel oil dosed on a freshwater community was studied in a model pond microcosm over 14...
Estimation of strong ground motions from hypothetical earthquakes on the Cascadia subduction zone, Pacific Northwest
T. H. Heaton, S.H. Hartzell
1989, Pure and Applied Geophysics PAGEOPH (129) 131-201
Strong ground motions are estimated for the Pacific Northwest assuming that large shallow earthquakes, similar to those experienced in southern Chile, southwestern Japan, and Colombia, may also occur on the Cascadia subduction zone. Fifty-six strong motion recordings for twenty-five subduction earthquakes of Ms???7.0 are used to estimate the response spectra...
Surface faulting along the Superstition Hills fault zone and nearby faults associated with the earthquakes of 24 November 1987
R. V. Sharp
1989, Bulletin of the Seismological Society of America (79) 252-281
The M 6.2 Elmore Desert Ranch earthquake of 24 November 1987 was associated spatially and probably temporally with left-lateral surface rupture on many northeast-trending faults in and near the Superstition Hills in western Imperial Valley. Three curving discontinuous principal zones of rupture among these breaks extended northeastward from near the...
Effect of chlorine in clay-mineral specimens prepared on silver metal-membrane mounts for X-ray powder diffraction analysis
L.J. Poppe, J.A. Commeau, G.M. Pense
1989, Clays and Clay Minerals (37) 381-384
Silver metal-membrane filters are commonly used as substrates in the preparation of oriented clay-mineral specimens for X-ray powder diffraction (XRD). They are relatively unaffected by organic solvent treatments and specimens can be prepared rapidly. The filter mounts are adaptable to automatic sample changers, have few discrete reflections at higher 20...

1989, Journal of Sedimentary Petrology (59) 147-161
Whitings, drifting clouds of water, milky because of suspended carbonate, have been claimed to originate from either the action of bottom-feeding fish or direct precipitation of calcium carbonate. Five cruises during different seasons were made to the Great Bahama Bank to collect data...
Rupture process of the Ms 6.6 Superstition Hills, California, earthquake determined from strong-motion recordings: application of tomographic source inversion
Arthur D. Frankel, Leif Wennerberg
1989, Bulletin of the Seismological Society of America (79) 515-541
We analyze strong-motion recordings of the Ms 6.6 Superstition Hills earthquake to determine the timing, location, spatial extent, and rupture velocity of the subevents that produced the bulk of the high-frequency (0.5 to 4 Hz) seismic energy radiated by this shock. The earthquake can be characterized by three principal subevents,...
Inverting measurements of surface slip on the Superstition Hills fault
J. Boatwright, K. E. Budding, R. V. Sharp
1989, Bulletin of the Seismological Society of America (79) 411-423
We derive and test a set of inversions of surface-slip measurements based on the empirical relation u(t) = uf/(1 + T/t)c proposed by Sharp and Saxton (1989) to estimate the final slip uf, the power-law exponent c, and the power-law duration T. At short times, Sharp's relation behaves like the...
Oxygen-isotope composition of ground water and secondary minerals in Columbia Plateau basalts: Implications for the paleohydrology of the Pasco Basin
P.P. Hearn Jr., W.C. Steinkampf, D. G. Horton, G.C. Solomon, L. D. White, J.R. Evans
1989, Geology (17) 606-610
Concentrations of 18O and deuterium in ground waters beneath the Hanford Reservation, Washington State, suggest that the meteoric waters recharging the basalt aquifers have been progressively depleted in these isotopes since at least Pleistocene time. This conclusion is supported by oxygen-isotope analyses of low-temperature...
A hybrid fast Hankel transform algorithm for electromagnetic modeling
W.L. Anderson
1989, Geophysics (54) 263-266
A hybrid fast Hankel transform algorithm has been developed that uses several complementary features of two existing algorithms: Anderson's digital filtering or fast Hankel transform (FHT) algorithm and Chave's quadrature and continued fraction algorithm. A hybrid FHT subprogram (called HYBFHT) written in standard Fortran-77 provides a simple user interface to...
