Publieke ruimte, parochiale plekken en passanten-openbaarheid : Jonge alleenwonende Amsterdammers over stedelijkheid
  • This thesis is an empirical study of the relationship between urbanities and urban public facilities centering on individual city dwellers of the options they face. More specifically, the aim of this study is to explore the perception by young
  • people living on their own of their day-to-day public environment. The study examines to what extent young Amsterdam singles focus on parochialised public spaces (places to be visited by members of the same social group while others are tolerated) outside

Mollusk record of monsoon variability during the L2-S2 cycle in the Luochuan loess sequence, China
  • The aim of this study is to expand the use of the mollusk assemblages as monsoon indices during the penultimate glacial-interglacial cycle in the Loess Plateau and then analyze the variability of the last two climatic cycles. Study of terrestrial
  • . These results agree with an increase in the regional aridity, since 500,000 yr, deduced from the study of the eolian flux in the northwestern pacific downwind from China.

The use of tracers to study sediment sources in three streams in northeastern Oregon
  • The use of tracers to study sediment sources in three streams in northeastern Oregon
  • This pilot study used sediment tracers to identify general source areas of channel bottom sediment within three tributaries of the Umatilla and upper Grande Ronde basins in northeastern Oregon. Land use in each stream was dominated by agriculture

Relationships between phases of the El Niño-Southern Oscillation and character of the tornado season in the South-Central United States
  • This paper begins with a brief descrition of ENSO. The procedures of this study include : process of regionalization, development of the cumulative annual SOI, determination of the tornado season and study period, and method of statistical analysis

The nature of small-scale flooding, muddy floods and retention pond sedimentation in central Belgium
  • This study investigates the spatial variation of small-scale flooding and muddy floods in rural areas in a medium sized study area (5516 km2) and the linkage with controlling factors. A strong relation exists between the nature of the problem
  • and the site in relation to topography and landuse. This study also focuses on the use of retention ponds as a control measure, the problem of siltation of the ponds and to their potential for estimating sediment yield.

Alluvial fan and catchment initiation by rock avalanching, Owens Valley, California
  • The North Long John alluvial fan of the Inyo Mountains piedmont, Owens Valley, was catastrophically initiated by a prehistoric (early Holocene?) rock avalanche. The key implication of this study is that not all fans of a particular piedmont
  • are of the same longetivity or stage of development. This study also points out that the geological hazards on the piedmont beneath triangular bedrock facets (rockfalls, roskslides, and rock avalanches) contrast with the dominantly debris flow or water-flow
  • hazards of the more mature fans. This study demonstrates that complications arise from differences in the timing of fan inititation, and with the degree of diachroneity.
