| Abstract | This study summarizes the development of a didactically
oriented interactive PC-based water resources planning training
model ( BNW>. It is basically a basin wide simulation model. The
objective of the BNW model is to gain a better understanding of
hydrologic phenomena prevailing in a water resources system and
to estimate how changes in the water resources system may affect
these phenomena.
The system starts from the known rainfall by u sing rainfallrunoff (NAM> mod el to calc ulat e the runoff hydrograph.
Subsequently it uses linear reservoir theory for river routing.
If there are reservoirs in the system, the regulation of
conservation reservoirs will be accounted for according to given
reservoir operation rule curves. Flood control reservoirs can be
operated either by deriving the optimal single reservoir release
policy or according to the predetermined constant target release
rule. Besides, the concept of nodes and arcs is used to re p resent
a physical water resources system. Flow discharge of the control
points ca n be computed and monitored by this model.
The BNW model is a general model. The sercan work with
this program by using an introductory example input data.
Besides, an imaginary river network system can be constructed and
used with its own input data . Furthermore the user can also set
up a mod e l system in accordance with a real world water resources
system.
At present the problems to b e considered in the BNW model
are limited to have not more than 30 nodes and 70 time steps
because of the PC computer memory. Since BNW program is written
in FORTRAN language, it can be transferred to t h e mainframe
computer easily. There fore the maxi mum number of time steps and
maximum node numbers could be extended if BNW program is working
on the mainframe . The BNW mod e l is a "working model" where as for
"real world" applications a calibration version is to be |
