Abstract
The scope of this work is the development of a computerized tool, named
PREVAL, for day-to-day sewer network management. This tool allows: 1) to
simulate hydrographs and pollutographs at the outlet of an urban catchment basin
and through control devices, 2) to make the validation and the filtering of
measurement data by using univariate or multivariate methods based on material
or analytical redundancy, 3) to provide hydraulic and hydrological models with
reliable data for the calibration stage, 4) to evaluate combined sewer overflows
in terms of quality and quantity and to check the conformity of the operation of
overflow devices with respect to prescribed constraints. PREVAL is the result of
a close cooperation between École de Technologie Supérieure, Hydro-Québec
and various partners such as the cities of Montreal, Laval and Verdun.
Keywords: control, overflow structures, pollution, validation.
1 Introduction
The management of sullage discharge into a natural environment requires a
qualitative and quantitative assessment of the outflow. The estimation of the
quantity and quality of sullage is based on measurements and on calibrated
hydraulic and hydrological models. The reliability of sullage discharge
assessment can be warranted only by the validation of discharge flow rate data.
1.1 Quantitative assessment
The quantitative assessment consists in estimating the frequency and the volume
of the sullage discharged into the natural environment by control devices. The
Keywords
control, overflow structures, pollution, validation.
