    A METHOD FOR INCORPORATING AGRICULTURAL RISK INTO A WATER RESOURCE SYSTEM PLANNING MODEL (1971)

    Notizen: Prior studies of water resource systems have considered risk from the point of view that only the system planners could react to the effects of the risk elements. However, users of water from a system also react to risk. When the quantity of water that a system can supply is subject to considerable variation, the reactions of the users of the water will often effect the benefits generated by the system and thus its optimal design characteristics. A simulation model of a reservoir-irrigation system is developed which incorporates the water users' reactions to risk in such a manner as to reflect their influence on the optimal design characteristics. A risk (convex) programming algorithm is incorporated into the model to reflect the water users' reactions to various levels of aversion to risk and degree of uncertainty in water deliveries. Response surfaces are generated as a result of performing the simulation at different levels of the design variables. An examination of these surfaces reveals the importance of including water users' reactions to risk in water resource system planning. The effects of different levels of risk aversion on the irrigation farmers' choice of crop enterprises are also examined.

    THE DEVELOPMENT OF A MODEL TO EVALUATE HYDROLOGIC RISK IN A WATER RESOURCE SYSTEM (1969)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 5 (1969), S. 0 
    Details
    ISSN: 1752-1688

    Thema: Architektur, Bauingenieurwesen, Vermessung , Geographie
    Notizen: A technique is described for analyzing a water resource system whose inflow is highly variable. The use of this technique requires not only that a mathematical model be developed of the physical, hydrological, and economic characteristics of the water resource system under study, but also that the economic benefits of the system, including full and partial water deliveries for irrigation development, be evaluated. Although developed independently of and simultaneously with the recently in this article includes some significant departures, such as the development of a complex revenue-loss function and water-shortage statistical characteristics for various reservoir sizes.

    THE DEVELOPMENT OF A MODEL TO EVALUATE HYDROLOGIC RISK IN WATER RESOURCE SYSTEM DESIGN (1970)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 6 (1970), S. 0 
    Details
    ISSN: 1752-1688
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Architektur, Bauingenieurwesen, Vermessung , Geographie
    Notizen: In this paper, a procedure for analyzing a water resource system with special emphasis on evaluation of acceptable economic risk due to occasional failures to deliver water is proposed. The basic methodology includes the development of a simple mathematical model which describes the physical hydrologic and economic characteristics of a single reservoir irrigation and city water supply system and an evaluation of economic benefits of the system with full and partial deliveries of water. The system is simulated for various combinations of decision variables (system magnitudes) and an optimum design is obtained by response surface technology. Emphasis is placed on the basic model and methodology although, in order to introduce some realism, the procedure is applied to data based on the existing reservoir system on the South Concho River in West Central Texas.
