With the increasing amount of data of time series in hydrological databases , it is very important in f100d forecasting and f100d dispatching to study the methods of retrieving similarity and then find the rules and tendencies contained in the hydrological time series 水文数据库中存在大量时间序列数据，发现水文时间序列中蕴藏的规律，有利于掌握水文数据变化规律和趋势，在洪水预报、防洪调度方面有重要的现实意义。
The comparison of the correction effect and detection efficiency of the two methods shows that the present method with rainfall center considered improves the stability of corrected result and the accuracy of real - time flood forecasting 运用闽江七里街流域1988 ~ 1998年45场洪水的暴雨资料，比较考虑降雨中心和不考虑降雨中心2种方法的修正结果和探测效率，结果表明，考虑降雨中心的方法增强了修正结果的稳定性，提高了实时洪水预报的精度。
At the same time , based on flood dispatching auto - monitoring system of shiquan reservoir , which is a hydrological data telemetering system and real - time flood forecasting system , this paper studies and develops the flood - dispatching system and perfects the flood - dispatching auto - monitoring system 同时在水库水调自动化监控系统基础上，即水情测报系统和洪水预报系统，本论文研究和开发了洪水调度系统，完善了水调自动化监控系统。
It is proved to be promising and valuable for these models with experimental results . ( 6 ) all these flood forecast models are examined in case studies , and their characteristics are obtained by performances evaluating , which can be considered as guidance in practical use ( 6 )针对各种基于学习机器的洪水预报模型，文中通过实例对它们的预报效果进行了评价，较为系统的对比了它们的特点，为它们在洪水预报领域内的产品化提供了指导。
Its primary task is how to present water level , disaster level , the measure to decrease disaster to decision maker , and its main goal is to combine modern flood forecast , dispatching decision , information technology with system support environment 如何把水情趋势，灾情大小，减灾措施等呈现在决策者面前是防洪决策支持系统的首要任务，而把现代洪水预报、防洪调度决策理论与信息技术有机结合在系统支持环境中，是这一系统需要达到的主要目标。
