An Introduction to Complex Systems in Environment Droits d'accès : non autorisé
Description : The environment is a social issue that continues to grow in importance. Its complexity, both cross-disciplinary and multi-scale, has given rise to a large number of scientific and technological locks, that can be solved using a complex systems approaches. Through this courses we will give some examp ...

Cascade phenomenology (An Introduction to Complex Systems in Environment) Droits d'accès : non autorisé
Description : Multiplicative cascade processes are frequently used as phenomenological models for the study of a variety of complex systems exhibiting fractal/multifractal behavior. In particular the energy dissipation field of fully developed turbulent flows has been most successfully modeled in such terms, phys ...

Dynamical Systems (An Introduction to Complex Systems in Environment) Droits d'accès : non autorisé
Description : When we describe the evolution of a system we use several variables, i.e. a set of magnitudes, functions of space and time, the values of which define everything we know about the system completely and unambiguously. Then, the evolution of the systems is given by the evolution of the set of variable ...

MultiScale Analysis :Multifractal (An Introduction to Complex Systems in Environment) Droits d'accès : non autorisé
Description : The multifractal analysis is an appropriate framework for addressing and modelling fields with high spatial and temporal variability, particularly with regard to the characteristics of non-uniformity of the phenomena and their extreme behavior. Therefore, the idea of applying this concepts to the de ...

Multiscale Analysis: Methods of Analysis (An Introduction to Complex Systems in Environment) Droits d'accès : non autorisé
Description : We gave in the courses Multifractal the meaning of the universal multifractal (UM) parameters and , in this courses we will introduce some techniques of estimation of UM parameters based on the scale invariance property of geophysical fields. The first method is the Trace Moment (TM) method which us ...

MultiScale Simulations (An Introduction to Complex Systems in Environment) Droits d'accès : non autorisé
Description : We have seen during the previous lecture the concept of cascade phenomenology and the different models that can be found in the literature. It has been showed the cascade generation is based on the scale invariance propriety and the multiplicative process. The use of simulation is increasingly comm ...

Resilience (An Introduction to Complex Systems in Environment) Droits d'accès : non autorisé
Description : Urban flooding is due to a lack of drainage in an urban area. Because of the impervious area, there is little open soil that can be used for infiltration and water storage. Nearly all the precipitation needs to be transfer to surface water or the sewage system. High intensity rainfall can cause floo ...

Source Of Complexity (An Introduction to Complex Systems in Environment) Droits d'accès : non autorisé
Description : We saw in the previous lesson some complex systems that can be found in environment. We also highlighted that there is non single definition of complexity. Through this lesson we will focus on the sources of complexity in a given system, what are the issues that can arise for the best model a comple ...

Spectral Analysis (An Introduction to Complex Systems in Environment) Droits d'accès : non autorisé
Description : We introduce in this lecture the spectral analysis which is based on the Fourier transform. The main objective of using this can of analysis in our studies is to check the scale invariance propriety of the studied field and also to identify the involved processes. The spectral analysis is widely use ...
