摘要
This paper summarizes studies conducted for the City of Fort Collins, Colorado, to determine the effects of prolonged droughts on the city's water supplies. As a result of the analysis, various water-supply strategies were developed to be used by the city for handling the problems associated with extreme droughts. This study utilized stochastic modeling coupled with water-resource-system modeling to evaluate drought effects on the water supplies of the city. A stochastic model was developed for the five river basins that account for the city's water supplies. The stochastic model was verified with 400 years of tree-ring data obtained for the area. Periods of records were then generated to determine potential droughts that could occur. Representative 1-in-20, 1-in-50, 1-in-100, and 1-in- 500-year droughts were selected for the analysis. © ASCE.
