  • Uncertainty in water management
  • Climatic variation ; Decision aid ; Drought ; Forecast ; Global change ; Natural hazards ; Uncertainty ; Water ; Water management ; Water resources
  • Water management is choice in face of bounded uncertainty. This papre presents some theories, as well as 3 principles of uncertainty, namely : of the minimum and maximum of uncertainty and of its immutability. Examples are cited of the undesirable
  • consequences of a failure to heed these principles. Methods of rational decisionmaking in conditions of uncertainty are presented, while methodological considerations are supported by examples of applications in water management.
  • Knowledge, uncertainty and physical geography : towards the development of methodologies for questioning belief
  • Concept ; Environment ; Knowledge ; Methodology ; Physical geography ; Risk ; Uncertainty
  • This paper argues for explicit assessments of uncertainty in environmental data and models as a necessary, although not a sufficient, condition for balancing uncertain scientific arguments against uncertain social, ethical, moral and legal arguments
  • in managing environmental systems. In particular, this paper aims to : demonstrate the importance of assessing uncertainty within a realist research framework; consider the nature of scientific uncertainty as the basis for developing methodologies
  • that question belief; and explore some important aspects of a methodology for evaluating uncertainties in environmental research.
  • Prospects for the open treatment of uncertainty in environmental research
  • Data processing ; Decision making process ; Environment ; Forecast ; Model ; Research ; Risk ; Uncertainty
  • This paper argues for more open treatments of uncertainty in environmental research. Such openness requires an appreciation of the social and psychological causes of uncertainty, the role of observations as imperfect and contingent expressions
  • of visible events, and the myriad ways in which scientific information can be misinterpreted, misused, or sidelined in environmental decision-making. The paper begins with a discussion of the nature and causes of uncertainty in environmental research
  • . A review of current treatments of uncertainty is followed by an analysis of the source-based approach to assessing uncertainty. Prospects for the open treatment of uncertainty are then discussed in terms of circumventing the three ‘myths of uncertainty
  • Risk, uncertainty and nuclear power
  • Uncertainty in regional climate modelling : a review
  • Climate ; Climatic change ; Global change ; Greenhouse effect ; Human impact ; Model ; Regional climate ; Scale ; Statistical bias ; Uncertainty
  • In this paper, the cascade of uncertainty from emissions scenario to global model to regional climate model is explored. The initial part of the discussion focuses on uncertainties associated with human action, such as emissions of greenhouse gases
  • . In the second part of the discussion, uncertainties associated with climate modelling are explored with emphasis on the implications for regional scale analysis. Such uncertainties include parameterizations and resolutions, initial and boundary conditions
  • inherited from the driving global model, intermodel variability and issues surrounding the validation or verification of models. The paper concludes with a critique of approaches employed to quantify or cater for uncertainties highlighting the strengths
  • Modelling commodity flows under uncertainty
  • Research policy and review 34 : the development of ideas of uncertainty representation
  • Numerous ideas are adressed, which can supplement the basic approaches to uncertainty associated with objective and subjective probability. They are gleaned from many disciplines, including philosophy, mathematics, and artificial intelligence
  • . This review of the literature highlights the need for additional research on a number of topics, and the synthesis of new approaches to uncertainty with more traditional decision analysis techniques.
  • The representation of knowledge and uncertainty in database of GIS geological maps
  • In this paper an analysis is carried out on the phases that characterize the acquisition of structural-geological knowledge and related different levels of uncertainty. Methodologies to represent geological uncertainty in GIS databases
  • Optimum firm location under factor-price uncertainty
  • This paper presents a cost-minimizing location model to investigate the theoretical impacts and implication of factor-price uncertainty on the optimum location decision of the firm in linear space. It will be shown that increased input price
  • uncertainty leads the firm to move its factory towards the site of the price uncertain imput.
  • Predicting regional climate change : living with uncertainty
  • Regional climate prediction is not an insoluble problem, but it is a problem characterized by inherent uncertainty. There are 2 sources of this uncertainty : the unpredictability of the climatic and global systems. So this review considers
  • the implications of climatic and global system unpredictability for regional climate prediction. Consequently the AA. regard regional climate prediction as a cascade of uncertainty. They understand regional climate change in terms of changes in the general
  • Advances in the study of uncertainty quantification of large-scale hydrological modeling system
  • Algorithm ; Concept ; Hydrology ; Land atmosphere interaction ; Methodology ; Model ; Quantitative analysis ; Uncertainty
  • This paper systematically reviewed the recent advances in the study of the uncertainty analysis approaches in the large-scale complex hydrological model on the basis of uncertainty sources (input data and parameters, model structure, analysis method
  • and the initial and boundary conditions). Also, the shortcomings and insufficiencies in the uncertainty analysis for complex hydrological models are pointed out. And then a new uncertainty quantification platform PSUADE and its uncertainty quantification methods
  • were introduced, which will be a powerful tool and platform for uncertainty analysis of large-scale complex hydrological models. Finally, some future perspectives on uncertainty quantification are put forward.
  • Dasymetric modeling and uncertainty
  • Entropy ; Estimation ; Household ; Methodology ; Model ; Modelling ; Population ; Spatial analysis ; Spatial distribution ; Tennessee ; Uncertainty ; United States of America
  • This article presents a new dasymetric methodology—the penalized maximum entropy dasymetric model that enables sources of uncertainty to be represented and modeled. It allows a rich array of data to be included, with disparate spatial resolutions
  • , attribute resolutions, and uncertainties. It also allows a rich array of data to be included, with disparate spatial resolutions, attribute resolutions, and uncertainties. It concludes by presenting an application that that includes household-level survey
