  • Die zeitliche Einstufung geologischer Prozesse für ingenieurgeologische Aufgaben im Bergbau und Bauwesen unter besonderer Berücksichtigung des Karstes (Temporal rating of geological processes for Engineering geological tasks in mining
  • Temporal rating of geological processes has great importance for carstification processes in salt and gipsum areas. Two problems are discussed : determination of age by geological methods and prognosis of recent geological processes using

  • An analysis of the distance parameter of spatial interaction model - A case of the greater Tokyo metropolitan area
  • This paper analyzes the distance parameter of spatial interaction model in the case of the greater Tokyo metropolitan area. The friction of distance is measured by the effect of the behavioral component. The production constrained entropy maximizing

  • Runoff modifications in forest areas
  • Data from representative basins demonstrate the moderating effect of forested areas on runoff. This reduction was analysed in detail for peak discharges and runoff coefficients.

  • A groundwater hypothesis for the origin of fire areas on the Northern Channel Islands, California
  • California ; Carbonisation ; Diagenèse ; Etats-Unis ; Fire area ; Géographie physique ; Northern Channel Islands ; Quaternaire ; Rubéfaction ; Sédimentologie
  • Pleistocene areas of red sediments and carbonized vegetation have in the past been interpreted as caused by fires of either natural or human origin. Some are associated with darkened mammoth and bird fossils, which have been considered as having
  • been burned by early man. Reevaluation of these so-called fire areas by interdisciplinary investigations indicates that the above phenomena are the result of low-temperature (up to 100o C), non heating processes occurring in groundwater.

  • Agricultural typology of the Alpine areas : Austria and Switzerland
  • In these Alpine areas, 6 groups and 12 combinations of types have been differentiated in 1975. This spatially differentiated agriculture in the highlands is highly correlated with the natural and non-natural conditions| it is also a result

  • Erosional processes, land use, landforms and soils, Khubetsoana area, Maseru in Sediment sources, sediment residence time and sediment transfer-Case studies of soil erosion in the Lesotho lowlands.
  • The type of land use and the management influence soil erosion with time. Gullies and rills generally occur on lower parts of the catchment area which are mostly occupied by Sephula, Maseru, Rama and Matela soil series. Rock-stripping occurs
  • on higher and rocky parts of the area.
