A stochastic hydro-geomorphological model for shallow landsliding due to rainstorm
  • A stochastic hydro-geomorphological model for shallow landsliding due to rainstorm
  • Honshu ; Japan ; Landslide ; Model ; Natural hazards ; Rainstorm ; Slope ; Slope dynamics ; Spatial distribution ; Stochastic model ; Thematic map
  • A prediction model of shallow landsliding is proposed. It considers not only the determininstic aspects containing slope stability, saturated throughflow and a soil (regolith) depth development, but also the stochastic aspects of intensity
Incorporation of hydrologic cycle elements into the Dynamic-Stochastic climate model
  • Incorporation of hydrologic cycle elements into the Dynamic-Stochastic climate model
  • Atmosphere ; Climatic variation ; Climatology ; Dynamic model ; Energy balance ; Evaporation ; Hydrology ; Hydrosphere ; Model ; Precipitation ; Stochastic model ; Thermal exchange ; Water cycle;Water circulation
  • The ways of incorporation of hydrologic cycle elements into the dynamic-stochastic heat and water exchange climate model are considered. Such approach enables to identify the main sources of precipitation climatologic variability.
A stochastic model for initial movement of sand grains by wind
  • A stochastic model for initial movement of sand grains by wind
  • Aeolian features ; Aeolian transport ; Model ; Stochastic model ; Threshold ; Wind ; Wind speed
  • A stochastic model for entrainment of sand grains by wind is presented through analysis of the forces exerted on a single spherical grain, coupled with fluctuations of wind velocity and the change in grain position on the surface, in order

A stochastic weather generator as a tool for the construction of climate change scenarios
  • A stochastic weather generator as a tool for the construction of climate change scenarios
  • weather model, a stochastic weather generator simulating daily values for elements of the climate. An attempt to verify the model was made on the basis of data for the Zamość weather station. Discussion of the results.
A stochastic cumulative scaling method applied to measuring wealth in Indonesian villages
  • A stochastic cumulative scaling method applied to measuring wealth in Indonesian villages
  • Stochastic cumulative scaling (Mokken scaling) is a technique for converting several dichotomous variables into a single ordinal or interval measure of some latent trait. After a brief review of scaling approaches developed by Guttman and Mokken
A stochastic model of the propagation of local fire fronts in New York City : implications for public policy
  • A stochastic model of the propagation of local fire fronts in New York City : implications for public policy
  • A stochastic model of block-loevel advancing contagious urban decay is presented under conditions of inadequate fire extinguishment services. It is based on earlier obsrvations that spread of urban decay in small areas involves sudden clusters
