The undisputable significance of water resources necessitates solving
problems related to the amount and distribution of water. However, existing
methods and the outcomes obtained via these methods are continuously criticized
and do not meet the expectations in terms of reliability. On the other hand, increasing need to plan
water resources and lack of alternative methods to determine the water
potential in areas where flow measurement does not exist make it impossible to
evade dependency on these methods. With this purpose generated flexible, comprehensive and reliable
runoff distribution map was formed on the basis of weighted overlay in parallel
to impact degrees of effective parameters. The calibration of the obtained map
was done on the basis of pixels based on both theoretical and empirical data.
As a result of the analyses, it was seen that an accurate runoff distribution
model that fully reflects the characteristics of the field can only be
developed by calibrating it based on the real flow data obtained from remote sub-basins
that are free from external interventions. It would be impossible to free the
theoretical approaches from errors since these approaches are related to amount
of water which has an active nature and interacts with factors that are beyond
measure. As a result of implementing the method on Ergene River Basin, the
sample basin, a surface runoff volume of an average183,45mm/year/m², i.e. a
total of 2100000000m³/year ±2% was
obtained for the basin and this result has at least 27% difference from the
results obtained with existing methods.
