Rh. Khatibi, HYDRAULIC CHARACTER OF FLOOD DRAINAGE SYSTEMS - PART-1 - HYDRAULIC BASIS, Proceedings of the Institution of Civil Engineers. Water, maritime and energy, 124(4), 1997, pp. 240-253
The wealth of professional experience gained in recent years clearly c
onfirms hydraulic intuition that flood drainage systems (FDS) often di
splay distinct hydraulic characters. This seems remarkable in a backgr
ound where the FDS configurations are potentially unlimited owing to (
a) geomorphological diversity and hydrometric complexity and (b) multi
-purpose utilitarian functions and subsequent attributes (such as land
use, environment, public perception), Since conflicts are inevitable
in these systems, a problem-solving procedure based on hydraulic model
ling and holistic appraisals has been developed. This paper argues tha
t such a problem-solving procedure may be enriched by identification o
f hydraulic characters to offer a sense of direction for obtaining ins
ights into the complexities of the FDS, Together with the case studies
presented in the companion paper (Paper 11321(1)), this paper present
s a review of prevailing hydraulic characters in the background of cur
rent open channel flow modelling practices. Based on the dominance of
spatially-distributed storage and dynamic effects and features such as
distributive and locally-governed effects, the following hydraulic ch
aracters were identified: attenuating, storing, responsive, retarding,
spatially-distributed, inertial, distributive and locally-governed sy
stems.
