Consideration of uncertainty factors in problems of groundwater dynamics.

摘要

The development of methods for the calculation of groundwater intake under conditions of incomplete initial information is presented. An inverse numerical method was used when constructing the membership function of the non-fuzzy function of well flow rate from fuzzy arguments. Flow rate equations for wells located in confined and unconfined aquifers are given. A forecast of long-range conditions of operating intake wells with periodically varying water withdrawal is provided in a fuzzy formulation. The developed method of solution was tested for calculating heat and moisture exchange processes in potato storage regime. Calculations and experimental studies were carried out for actively ventilated bulk storages (1000-10 000 tonnes in volume) in the Orel Oblast and Cheboksary and Kursk cities, Russia. Results showed that if the flow becomes turbulent and, consequently, its heat conducting properties improve, an increase of the air flow rate in the interlayer cannot improve its effectiveness..
