ABSTRACT: The numeral trait of aquiferous zones in flowage studies and estimations
is under most parts of nation. In this study Karaj aquiferous zone in Alborz
province was surveyed from the view point of form, the agglomeration of
drainage net length of channel and space. The orientation of hillside was
specified as the affective factor on creating and streaming the flowage. A flow
aggregating hydrological model for the studied zone was prepared and amount of
the flow is mostly in which parts of the zone the delay and centralization time
in the zone was evaluated and the related diagrams were derived. Finally, the
zone was divided into 4 main subzones and their drainage nets were ranked and
by 4 factors namely, space, length of canal, drainage aggregation and branch ratio
affecting on performance of the zone from the view of from and appearance was
surveyed. The factors interfering in SPSS software and their correlations were
specified and specific coefficients stand in their related charts. By
considering in the zone width and charts it is specified which of the sub zones
has the most flowage potential from the view of the zones physical and numeral
qualifications. All plots were prepared using GIS and WMS software and the
studied zone’s hydrograph was depicted.
