9520109 Georgakakos The California flash floods of winter 1995 will be studied by surveying the affected areas, collecting flood data from Federal and State agencies and by using historical, topographical, hydrometeorological and other database information to develop flash flood potential maps for critical areas in the state of California. Data of this event will be used to validate the estimates and, if necessary, to modify the design of the flash flood potential algorithm. Once validated, the mathematical model will be used in a series of sensitivity experiments to provide, quantitative answers to questions such as the effect of land use changes on the magnitude and recurrence interval of the flash flood potential index and the role of antecedent soil moisture of mountainou terrain. The resultant prototype flash flood potential maps will be of value in activities such as in the design of the safety criteria of small dams, in the assessment of the flash flood risk, and in early warning when combined with radar rainfall data. ***

9520109 Georgakakos 将通过调查受影响地区、从联邦和州机构收集洪水数据并利用历史、地形、水文气象和其他数据库信息来研究加州 1995 年冬季的山洪暴发，以绘制该州关键地区的山洪潜在地图加利福尼亚州。 该事件的数据将用于验证估计，并在必要时修改山洪潜在算法的设计。 一旦经过验证，该数学模型将用于一系列敏感性实验，为诸如土地利用变化对山洪潜在指数的幅度和复发间隔的影响以及先前土壤湿度的作用等问题提供定量答案。山区地形。 由此产生的原型山洪潜在图对于小型水坝安全标准的设计、山洪风险评估以及与雷达降雨数据相结合的早期预警等活动具有重要价值。 ***
