Abstract
Now the information technologies such works, database and data
acquisition are progressing rapidly, and have contributed a lot in many kinds of fields. It is
important to research how to apply these new technologies to irrigation management to
forecast the flood or drought , improve the utilization efficiency of water resources .It will
e an important part of irrigation works. As a method of preventing flood with low
cost and short period construction and high efficiency .It is most significant to the advance
of the economy and the social stability. The automatic monitoring and forecasting system
of flood regimen is very useful in flood prevention.
J2EE is an architecture using java 2 platforms to plicated enterprise
information application development, deployment and management works. J2EE system
structure offer intermediate level integrated frame to meet high usability, high reliability
and scalability. Good guide supports and deploy application has strengthened the security
mechanism, have improved performance.
The main work and achievements are following:
(1) Analyze the automatic flood monitoring system model, research the systematic
function goal and performance demand, on this basis, this thesis analyze the system
