Design of a hydrologic observation database system

Abstract

To reduce losses caused by flood damage year by year, hydrological information collection and forecasting were the urgent need. So, a hydrological database system was designed based on database principle and software engineering theory. The software was developed with the J2EE technologies of Jsp, JavaBean and Servelt, and the development environment was MyEclipse. This database system realizes the functional modules including rain information collection, query, analysis, calculation, report management, instant forecasting and historical flood simulation. The software can finish centralized management of real-time data, and computation results are objective and intuitive, affording effective decision support. Workload is reduced greatly. It plays important role on developing water resource, prevention of flood and drought disasters and protection of water environment, too. © 2011 Springer-Verlag Berlin Heidelberg.
