Description

The publication offers knowledge on the subject of processes that occur in ambient air, water, soil and during physical pollution of the environment. The presented information covers principles applicable to mathematical modelling of environmental processes and levels of such models. The theoretical knowledge encompasses equations of transport processes and their systems, used for mathematical modelling of environmental processes in the atmosphere, hydrosphere and geosphere. The publication teaches to compose mathematical analogues for physical models and methods for the solution of numerical equations. It shows how to solve problems numerically as well as to analyse and test numerical results.

The publication gives calculation methods for modelling of environmental processes. Computer modelling is used to solve most problems. It describes four computer modelling programs used for the simulation of environmental processes: ADMS – 4, VS2TDI, CADNA A, Phoenics. Phoenics program is intended for modelling of processes in ambient air and liquids. ADMS-4 simulates the distribution of pollutants in ambient air. VS2TDI gives practical insights into modelling of transport of pollutants in soil. Practical skills for numerical assessment of sound wave diffusion are gained using the modelling program CADNA A.

Not only environmental protection experts have to be able to measure environmental parameters using various devices, but also perform mathematical modelling of environmental processes and undertake computer-based analytical or numerical solution of equations.

This textbook is intended for master’s and doctoral degree students in the study field of environmental engineering of technical universities, and specialists seeking for professional development.
