Interaction of above / below urban grounds : an experimental facility developed to analyse computer modelling results
نویسندگان
چکیده
This research undertaken at the University of Sheffield aims to provide a better understanding of the interaction above/below ground urban floods. A newly constructed unique experimental facility has been developed in the water lab, and it includes a sewer system, composed by 3 main pipes, 6 manholes and a CSO (Combined Sewer Overflow), and a preliminary urban surface with the slope 1/1000. This paper describes the experimental facility that has been built, how the system is managed in real time control using Labview software, which methodology will be applied to increase the understanding of the exchange flow-rate between an urban surface and a below sewer system and it presents preliminary results obtained comparing physical results with computer software results such as InfoWorks, SWMM and SIPSON (NUNO MELO et al., 2012). Finally, the PIV system (Particle Image Velocimetry) that will be used for the acquisition of the images during the event of flooding is briefly explained. This last step will be useful for the comparison between 3D digital maps created by standard software against real physical results.

SPOT PATTERNS IN GRAY SCOTT MODEL WITH APPLICATION TO EPIDEMIC CONTROL
In this work, we analyse a pair of two-dimensional coupled reaction-diusion equations known as the Gray-Scott model, in which spot patterns have been observed. We focus on stationary patterns, and begin by deriving the asymptotic scaling of the parameters and variables necessary for the analysis of these patterns. A complete bifurcation study of these solutions is presented. The main mathematic...
متن کاملApplication of Fuzzy Decision-Making to Facility Layout Planning
This research proposes a vigorous methodology based on the fuzzy set theory to improve the facility layout process. Using natural language, the fuzzy set theory is an appropriate tool for controlling complex systems such as facility planning. The closeness rating between departments in a plant depends on qualitative and quantitative factors. Some of these factors may have a greater effect on th...

متن کاملQuantifying and Analysing Neighbourhood Characteristics Supporting Urban Land-Use Modelling
Land-use modelling and spatial scenarios have gained increased attention as a means to meet the challenge of reducing uncertainty in the spatial planning and decision-making. Several organisations have developed software for land-use modelling. Many of the recent modelling efforts incorporate cellular automata (CA) to accomplish spatially explicit land-use change modelling. Spatial interaction ...
متن کاملEvaluation of social livability components and their interpretive structural modeling, case study: Qaen city
Introduction In the current century, known as the century of cities, a significant part of the world's population lives in cities and the trend of increasing urbanization continues. In such circumstances, the important question is to what extent cities are suitable places for human life. Hence, the concept of urban livability and livable city has become one of the most widely used concepts in...
