URBIS SOERE Urban Environment
A long term observation system for research and experimentation on urban environment
This system of observation and experimentation constituted in 2010 , will :
extend transverse theme.
This system is based on three French cities, experimental sites named “observatories in urban hydrology :
OPUR
(Observatoire des Polluants URbains, i.e. the observatory of urban pollutants)
has been created in the Paris area, in 1994,
by researchers from the LEESU which is a laboratory
belonging to Paris Est University.e
OTHU
was created in Lyon in 1999 by researchers from 12 laboratories belonging to 9 scientific institutions in association with the metropolis of Lyon and the water Agency Rhône Méditerranée Corsica
ONEVU
(Observatoire Nantais des EnVironnements Urbains, i.e. the Nantes observatory of urban environments) was created in Nantes in 2006 by researchers of LCPC which is a public laboratory specialised in civil engineering and public infrastructures.
Concrete objectives planed are:
(1) to optimize and maintain the monitoring network;
(2) to ensure the quality of the scientific research program;
(3) to coordinate the scientific issues and their distribution between different observatories and
(4) to implement information system allowing a common porting of data and promote achievements .
Observatories common or specific research theme
Processes studied within URBIS
Like Hurrbis, URBIS concern all processes linked to the flow of water in the urbanized environment subject to natural stress (climate mainly) and anthropogenic associated with urban practices (activities in the city), their operational management (technical, socio-economic and political of the town strategies) and its effects on the city and on environments (physical effects : thermal energy, morphological; biological, chemical and socio-economic).

The scientific objectives of this system
The scientific objectives of this new structure are:
- identifying the tracers or physicochemical species representative of the multitude of pollutants and contaminants present and their compound effect; developing methods that prioritize the contaminants of critical importance within a given territory;
- identifying and quantifying the transfer sources, pathways and vectors as well as the pools of contaminants, by integrating the entire water cycle (in particular the compartments of soil, the aquatic environment (surface water and groundwater) and atmosphere, which are relatively absent from many urban hydrology research programs) and taking into account new storm water management modes;
- assessing the impacts of various types of discharges on the biocenosis and biotopes (aquatic ecosystems and urban soil); this includes the investigation of interactions between sources, pathways and impacts (e.g. the share of contamination carried by the particulate phases compared to the dissolved phases);
- applying this knowledge to build predictive or decision-making models at various spatial and temporal scales in order to promote analyses of performance and action strategies (e.g. in terms of control at the source, real-time management, soil cover) involved in storm water management;
- identifying the procedures for transferring and assimilating these tools by actors in the urban development process.
