Common MP simulation. The hydrological databasemanagement system, furthermore, stores real time data as
well and it is also possible to prepare real time flood
forecast system by combined use of this data andconcurrent computing facility of multi simulation project
incorporated in Common MP Ver1.2. (5)Table: Comparison of data volume which can beacquired in a lumpDatahydrologicalacquisition toolPeriod

dataThe pastIntroduction
The hydrological database management system(1), of
which national hydrological data under the jurisdiction of
the Water and Disaster Management Bureau of Ministryof Land, Infrastructure, Transport and Tourism, that canbe inspected and acquired by anybody, is commonlyutilized. However, there have been inconvenient points
such as a distinct restriction on the data volume accessible
in a lump for analysis and a difficulty in working withapplication software for water ・ material circulation
analysis. In addition, it has been an important issue toconfigure an interface to the database in Common
MP(2) , a software developed and operated by NILIM, andimprove usability of the analysis application, with theobjective that engineers can easily conduct hydraulic andhydrological analysis and make a technical judgment
based on ample studies and so forth.
Therefore, we report here that a hydrological dataacquisition tool(3) (Figure), which can acquirehydrological data in a lump from the hydrological water
quality database, has been developed and released.

Outline of hydrological data acquisition tool
The hydrological database management system isequipped with standard interface, (4) which can provide
data in reply to requirements of the client PC, and an
application software conforming to this can freely acquiredata.
Common MP hydrological data acquisition tool isprepared in conformity with this standard interface and it
is possible to acquire data from more observation stations
and for longer duration comparing to using web browser(Table) and accordingly, it is convenient for analysis tobe conducted. Also, acquired data can be used as it is in

Future development
A new function to connect hydrological data tosoftware by developing the hydrological data acquisition
tool was added. It is scheduled, from now on, toenhance software which utilizes this tool and to promote
application to practical business such as river projects.
