PREPARATORY MODULE FOR THE OBJECT-ORIENTED MODELING OF URBAN TERRAIN HYDROLOGICAL RESPONSE
ABSTRACT: This research aimed
at preparing an object-oriented module to use in conjunction with an object-oriented urban
terrain hydrological response
model. The module
serves to capture terrain data
and prepare them and make them fit as input to the core part of the urban
terrain model. This research had constructed the module. It engages five
classes of object, which
give it capability
to faithfully capturing
terrain hydrological features and other relevant data, and arrange them in such a way as to serve as fit input to the core part
of the urban
terrain model. The
module represents an
urban terrain by meshing
it unto a
network of rectangle
object elements. In
order to overcome
edge problems associated with the meshing, utilizing smaller size of
elements (hence higher number of elements) and weighted average in terms of
‘within a cell contained terrain-sheds
areas’ were advised.
It also strongly
encouraged the invention
of a more automate ways of terrain data capturing,
to replace the manual data entry procedure still utilized in this module.
Key Words: Edge problems;
hydrological response; object-oriented approach;
preparatory module; terrain-sheds; urban terrain model
