TELEMAC MODELLING : Objectives Our case study simulates the impact of a recycled water discharge (from the station STEP3 ) on the swimming water quality through an off-shore emissary. For that purpose, we monitored the dispersion plume of COD and BOD coming from the emissary that is 1600 m far from the coast and laying at –23m depth. The objective of this study is to know how the polluants are dispersed in the Gulf of Hammamet (plume extent, affected areas); Even if the rejections are conform to the national standards this will allow us to implement an early warning system and action plan in the case of break down of the treatment station or over-flow; Sustainable management of STEP3 can be done thanks to this study.

WATERWARE: Water balance WP03: ANALATICOL TOOLS, MODELS
WATERWARE: RRM & WRM modelling Strategy adopted : • Implement RRM model for each sub-catchment in which there is one or more dams • Gather the other sub-catchments in a unique hydrologic unit • In a second step, when inplementing WRM model, every unit is considered as a start node that supplies one or more reservoirs • Connect the outflows of all reservoirs to obtain a unique entry for the surface water
WATERWARE: RRM modelling Sub-catchments : 08 Sub-catchments : 12 Reservoirs : 09
