STADIA SURVEYING : THEORY OF STADIA MEASUREMEHTS

The fundamental principle upon which stadia measurements are based, is the geometrical one that the lengths of parallel lines subtending an angle are proportional to their distances from its apex.

Methods and Techniques in Urban Engineering

The purpose of this Book is to explain the concepts of urban engineering and to highlight some of the challenges faced by this discipline. The overall idea is to describe how urban engineering relates to other areas of engineering expertise, particularly within the context of civil engineering. To do this we have drawn mainly on our own professional and academic experience, fleshed out by an examination of the relevant literature available both in Brazil and further afield. At the outset it should be said that most of our observations focus on the city of São Paulo where our present professional concerns lie. However, in future works we hope to extend our approach beyond the confines of São Paulo in an effort to broaden and improve our understanding of the concepts underlying urban engineering as a necessary prelude to enable us to supply useful guidance for researchers, experts and students keen to work alongside the engineering professionals currently employed in our cities.

Literature review on the geologic aspects of inner shelf cross-shore sediment transport

This literature review addresses sediment transport across the inner portion of the continental shelf, also referred to as the shoreface, or, as in this report, the inner shelf (Figure 1). The inner shelf extends from the seaward edge of the surf zone to the landward edge of the continental shelf. It is affected by the strong agitation that results from sediment resuspension caused by shoaling of nonbreaking waves. The inner shelf is frictiondominated by both bottom and sea-surface boundary layers which overlap and frequently occupy the entire water column (Wright, in press). The inner shelf differs from the surf zone, which is also characterized by strong agitation of the bed by waves. The bed of the surf zone, however, is affected by the bore-like translation of waves following wave breaking (Komar 1976), and by wave-induced longshore currents and rip currents.

Topographical surveying: including: Topographical surveying

The object of Topography is to determine the relative positions of points of the earth's surface, that can be referred without error to a tangent plane, and therefore independent of the sphericity of the globe. The operations of a topographical survey, consequently, are two namely, to first project a system of points upon such a tangent plane ; and, secondly, to find the distances of the same above or below the plane; or, in other words, to measure the lengths of the projecting normals. The first process is ordinary surveying; the second, levehng.The results of a topographical survey are laid down in a so-called topograpliical map, which is a representation or complete image of the ground on a reduced scale.

Topographical maps are of the greatest convenience in locating railroads or other roads, in planning irrigation works, draining Avorks, in mining enterprises, in military operations, &c., &c. In a topographical map the configuration of the ground is reduced to an image, which represents to the eye a large area at one glance,which in nature could not be view edbut by many separate inspections ; therefore, the judgment about the relation of the different parts of the work will be a clearer and more intelligent one. This refers especially to mining work, where very frequently the problem occurs, to strike a vein with a tunnel in a certain level. In this problem a correct topographical map will often save the mining company several hundred feet of tunnel work, or, in other words, thousands of dollars.

Air Pollution

Although the climate of the Earth is continually changing from the very beginning, anthropogenic effects, the pollution of the air by combustion and industrial activities make it change so quickly that the adaptation is very difficult for all living organisms. Researcher's role is to make this adaptation easier, to prepare humankind to the new circumstances and challenges, to trace and predict the effects and, if possible, even decrease the harmfulness of these changes. In this book we provide an interdisciplinary collection of new studies and findings on the score of air pollution.
