  • Khuluse, S; Stein, A; Debba, Pravesh (2011-03)
    Early development of Extreme Value Theory (EVT) was motivated by a need to quantify the probability of unusually large (or small) events in hydrology and climatology. The current challenge in modelling extremes is how to ...
  • Debba, Pravesh; Carranza, EJM; Stein, A; Van der Meer, FD (Springer Berlin, 2008-08)
    This paper describes a quantitative methodology for deriving optimal exploration target zones based on a probabilistic mineral prospectivity map. The methodology is demonstrated in the Rodalquilar mineral district in Spain. ...
  • Debba, Pravesh; Stein, A; Van der Meer, FD; Carranza, EJM; Lucieer, A (Springer-Verlag Berlin Heidelberg, 2008-06)
    This paper presents a statistical method for deriving the optimal prospective field sampling scheme on a remote sensing image to represent different categories in the field. The iterated conditional modes algorithm (ICM) ...
  • Zhao, T; Debba, Pravesh; Stein, A (International Society for Photogrammetry and Remote Sensing, 2008-07)
    Spatial sampling optimization is an important issue for both geo-chemists and geo-statisticians. Many spatial sampling optimization methods have been previously developed. In this paper, we present a spatial simulated ...
  • Khuluse, S; Dowdeswell, M; Debba, Pravesh; Stein, A (2010-11)
    Flooding is often associated with heavy rainfall. Hence quantifying the probability associated with heavy rainfall events is useful in hydrology for design flood estimation and mapping Rainfall varies over time and space, ...
  • Debba, Pravesh; Carranza, E; Stein, A; Van der Meer, F (ee publishers, 2010-03)
    This research describes a quantitive methodology for deriving optimal exploration target zones based on a probalistic mineral prospectivity map.The Rodalquilar mineral district is located in the Sierra del Cabo de Gata ...
  • Debba, Pravesh; Carranza, EJM; Stein, A; Van der Meer, FD (Free and Open Source Software for Geospatial Conference (FOSS4G), 2008-09)
    This research describes a quantitative methodology for deriving optimal exploration target zones based on a probabilistic mineral prospectivity map. In order to arrive at out objective, we provide a plausible answer to the ...

  • Debba, Pravesh; Carranza, EJM; Stein, A; Van der Meer, FD (2009-08)
    This research discusses a novice method for sampling geochemicals to characterize mine tailings. Researchers model the spatial relationships between a multi-element signature and abundance estimates of secondary iron-bearing ...
  • Debba, Pravesh; Carranza, EJM; Stein, A; Van der Meer, FD (IEEE, 2009-07)
    The paper describes a novice method for sampling geochemicals to characterize mine tailings. The author’s model the spatial relationships between a multi-element signature and, as covariates, abundance estimates of secondary ...
