This book reports on the development of applications of physical-mathematical models that are well-established in academic literature, and which can contribute to improving water and soil management, since their application promotes greater knowledge of the variables involved, and the numerical results can contribute to decision-making in situations of agricultural production or environmental conservation. The distinguishing aspect of this work is the fact that it was built through an academic structure based on the integration of teaching, research and university extension. The authors believe that the importance of the work lies in promoting a better use of the energies and time of teachers, academics and technicians, as well as a more efficient use of the material resources made available in university environments. The motivating question is: is it possible to harness this potential energy, present in all academics, and under the influence of the teachers' command, the continuity of the rhythm imposed by curricular classes, and the motivations brought about by research and extension, to carry out developments that contribute to our society?
