This paper reviews the modelling work carried out in a major urban
drainage project: the development of the Integrated Master Plan for the catchments of all the watercourses that cross the city of Buenos Aires (30.000ha and 3.5million inhabitants). This city is a very dense and consolidated urban city with a complete culverted drainage network that dates from 1919/1940 (existing trunk culverts are 20m wide and 4m height). The rapid increase in population (mostly fed by internal migration from the interior of the country) coupled with the associated development of paved roads, has produced a dramatic increase in the runoff from rainfall, resulting in severe flooding in more than 30% of the city area for
events with a frequency as low as two years.

Integrated simulation of urban drainage system and receiving
water body during rainfall events for both quantity and
quality aspects
This work describes a mathematical model for the integrated simulation of the urban drainage system and the receiving
water body during rainfall events.
