Effects Of Urbanization On The Hydrologic Regime Of Johnson Creek, Portland, Oregon, William Vandewater Clement
Effects Of Urbanization On The Hydrologic Regime Of Johnson Creek, Portland, Oregon, William Vandewater Clement
Dissertations and Theses
The Johnson Creek watershed, Portland, Oregon, has undergone urbanization at an increasing rate. Excessive flooding has occurred in the lower portions of the watershed, resulting in an estimated 1.5 million dollars worth of flood losses annually. In attempts to mitigate the flooding damages millions of dollars have been spent to channelize the creek, and over 200 thousand dollars has been spent during the last 20 years on preliminary feasibility studies alone.
The author saw a need to verify that there has been a change in the rainfall-runoff relationships in the upper Johnson Creek basin since 1941 and to quantify this …
Barbados Ridge; Inner Trench Slope Sedimentation, William J. Cleary, H. Allen Curran, Paul A. Thayer
Barbados Ridge; Inner Trench Slope Sedimentation, William J. Cleary, H. Allen Curran, Paul A. Thayer
Geosciences: Faculty Publications
Quaternary sediments of this inner trench slope are chiefly foraminiferal-pteropod-nanno oozes that have been reworked and/or emplaced by gravity currents. These oozes are mixed with volcanogenic sediments and minor amounts of material derived from the insular shelf. Reworking occurs on topographic highs where fines are winnowed out and mass wasting and gravity currents are initiated; these processes ultimately result in the leveling of irregular floors of deeper, intervening slope basins. Petrographic analyses of graded intervals from the basin floors and slopes reveal the sands to be mixtures of planktic foraminifers (35%), pteropods (10%), and fresh, angular volcanic detritus (10-90%). On …

Tracemaking Activities Of Crabs And Their Environmental Significance: The Ichnogenus Psilonichnus, Robert W. Frey, H. Allen Curran, S. George Pemberton
Tracemaking Activities Of Crabs And Their Environmental Significance: The Ichnogenus Psilonichnus, Robert W. Frey, H. Allen Curran, S. George Pemberton
Geosciences: Faculty Publications
Modem crabs are common inhabitants of shallow subtidal, intertidal, and supratidal environments, and many crabs are capable of producing traces that can be preserved in the rock record. The first crabs, Early Jurassic in age, probably were not fossorial. By Cretaceous time, however, diverse endobenthic lineages were established. Many representatives of these lineages undoubtedly produced domiciles that are preserved in shallow marine to quasimarine sediments and that should be useful in characterizing the depositional environment of the sediments. Nonetheless, most such dwelling structures have been studied little and remain essentially unnamed.
The ichnogenus Psilonichnus Fiirsich is amenable to the taxonomic …
Urban Lead In Minnesota: Soil Transect Results Of Four Cities, Howard W. Mielke, Sara Burroughs, Randall Wade, Timothy Yarrow, Paul W. Mielke
Urban Lead In Minnesota: Soil Transect Results Of Four Cities, Howard W. Mielke, Sara Burroughs, Randall Wade, Timothy Yarrow, Paul W. Mielke
Journal of the Minnesota Academy of Science
The focus of this field study was the development of a soil collection and analysis method for the rapid assessment of urban lead (Pb) buildup in four Minnesota cities, Minneapolis, St. Paul, Duluth, and Rochester. The results show that soil Pb buildup is mainly a function of urban size, although specific geographic factors, such as a bluff that constrains city development along a narrow corridor, also play a role in Pb distribution and concentration. Maximum urban Pb concentrations were approximately 25, 70, and 100 times rural soil Pb levels, in Rochester, Duluth, and the centers of Minneapolis and St. Paul …

Llaffs - A Lightning-Locating And Fire-Forecasting System, United States Department Of Agriculture, Forest Service
Forestry
This publication contains programs and documentation to implement an algorithm for calculating lightning fire probability. This calculation is based on a model originally developed for the National Fire-Danger Rating System. The model algorithm estimates the probability that a lightning discharge from cloud to ground will ignite a fire in fuels at the ground terminus of the lightning. Probability is estimated using variables that are measures of the fuel state and type, rain, and lightning. Details of the model can be found in Fuquay and others (1979), Latham (1979), and Fuquay (1980).

Classification Of Pseudokarst Forms In Czechoslovakia, Jan Vitek
Classification Of Pseudokarst Forms In Czechoslovakia, Jan Vitek
International Journal of Speleology
The paper is a geomorphological classification of pseudokarst forms in Czechoslovakia/Bohemien Massif and the Carpathians. In the author’s opinion, forms occurring in non-carbonate rocks, are morphologically and often genetically analogous to the forms of karst relief, and are pseudokarst phenomena. They are divided according to their size into macroforms in sandstone morphostructures of the Bohemian Cretaceous Basin some types of rocky valleys, water-shed plains and ridges, forming rock cities in some places, mesoforms with six types of caves, sinkholes, rock perforations and several rock phenomena and microforms such as weather pits and niches, lapies, etc.. The most prominent pseudokarst phenomena …
Impact Of Urban Stormwater Runoff On The Water Quality Of The Subsurface Lost River, Bowling Green, Kentucky, Donald Rice
Impact Of Urban Stormwater Runoff On The Water Quality Of The Subsurface Lost River, Bowling Green, Kentucky, Donald Rice
Masters Theses & Specialist Projects
Bowling Green, Kentucky is located in a distinctive karst region, characterized by subsurface drainage. The Lost River is a large subsurface stream which flows beneath the city. It receives much of the stormwater runoff from Bowling Green, since most of the city's runoff is directed underground. Significant pollutants in Bowling Green's stormwater runoff were identified from water quality test results of storm event grab samples, and a composite sample, of runoff entering the urban By-Pass Cave. Water quality test results were also obtained from storm event grab samples, and a composite sample, of the Lost River at the Blue Hole …

Uranium-Series Age Of The Eel Point Terrace, San Clemente Island, California, D. R. Muhs, B. J. Szabo
Uranium-Series Age Of The Eel Point Terrace, San Clemente Island, California, D. R. Muhs, B. J. Szabo
United States Geological Survey: Staff Publications
Uranium-series analysis of the coral Allopora californica Verrill from the 2nd, 32-m Eel Point terrace on San Clemente Island, California, has yielded an age of 127,000 ± 7,000 yr. The Eel Point terrace is thus correlative with numerous terrace localities on the southern California mainland, with coral reefs on Barbados and New Guinea dated about 120,000 yr, and with substage 5e of the marine oxygen-isotope record. A tectonic uplift rate of about 0.20 m/1,000 yr has been calculated assuming a sea level slightly higher than the present one at the time of terrace formation. Extrapolation of this uplift rate allows …

Flume Experiments On Bedforms And Structures At The Dune-Plane Bed Transition, Francis P.J. Lockett
Flume Experiments On Bedforms And Structures At The Dune-Plane Bed Transition, Francis P.J. Lockett
Theses and Dissertations (Comprehensive)
A tiltable, recirculating flume, 18 metres long and 76 cm. wide was used to investigate bedforms and structures near the transition between dunes and a plane bed for a moderately sorted, coarse sand. At Froude numbers ranging from about 0.4 to 1.0, three dune types developed: (1) asymmetrical (triangular) dunes, (2) convex (symmetrical) dunes and (3) humpback (whaleback) dunes. Asymmetrical dunes had gentle, long stoss sides and steep, short lee sides and contained cross-stratification with a maximum dip mostly about 30 degrees to 35 degrees. Flow separation and avalanching were strongly developed to the lee of these dunes. Convex dunes …
