ABSTRACT
A hydrological-hydraulic quasi-2D multilayer simulation model is presented.
It models the dominant hydrological processes involved in the rainfall-runoff
transformation in rural and urban environments. The modeling structure
is based on the well-known schemes of intercon-nected cells, with the original
addition of a large set of linking laws. These allow flow simulation in
both surface runoff and networks of closed conduits. The model was developed
to embrace different scales of rural and urban storm drainage from streets
to river basins, and to cover different levels of detail, from river basins
with a resolution of 0.10 elements/km2 to drainage micro basins
with 600 elements/km2 . The conceptual model and a synthesis
of several relevant applications are presented here. The results obtained
were satisfactory, and show that the real process of rainfall-runoff transformation
flowing in a single layer and in two interconnected layers (surface runoff
and networks of closed conduits) can be successfully modeled.
