Part of topic : Projecting and manufacturing the ambiances of tomorrow; International audience; Our living ambiances are about to change their structural character in a decisive way: Intelligent technologies are increasingly invading our traditionally stable and static habitats and turn them into responsive environments with additional technology driven dynamcis – such intelligent ambiences seem to be the future of our everyday life environment. Their design and their impact on our bodily experience is still an open research field, in which ‘atmosphere’ and ‘ambience’ seem to become core notions that demand new models of the human-environment relationship. Our current artistic research project tries to model a responsive environment in which people can explore and experience the epistemological and behavioural impact of new technologies.

Abstract. Highly distributed temperature data are used as input and as calibration data for a temperature model of a first order stream in Luxembourg. A DTS (Distributed Temperature Sensing) fiber optic cable with a length of 1500 m is used to measure stream water temperature with a spatial resolution of 0.5 m and a temporal resolution of 2 min. With the observations four groundwater inflows are found and quantified (both temperature and relative discharge). They are used as input for the distributed temperature model presented here. The model calculates the total energy balance including solar radiation (with shading effects), longwave radiation, latent heat, sensible heat and river bed conduction. The simulated temperature along the whole stream is compared with the measured temperature at all points along the stream. It shows that proper knowledge of the lateral inflow is crucial to simulate the temperature distribution along the stream, and, the other way around stream temperature can be used successfully to identify runoff components. The DTS fiber optic is an excellent tool to provide this knowledge.
