River Hydraulics


Book Description

This manual presents the techniques and procedures that are used to investigate and resolve river engineering and analysis issues and the associated data requirements. It also provides guidance for the selection of appropriate methods to be used for planning and conducting the studies. Documented herein are past experiences that provide valuable information for detecting and avoiding problems in planning, performing, and reporting future studies. The resolution of river hydraulics issues always requires prediction of one or more flow parameters; be it stage (i.e., water surface elevation), velocity, or rate of sediment transport. This manual presents pragmatic methods for obtaining data and performing the necessary computations; it also provides guidance for determining the components of various types of studies.

Durability of Geotextiles


Book Description

During the past decade, the use of geotextiles has increased significantly in a wide range of civil engineering applications: road construction, coastal engineering, stabilization of slopes and retaining structures, reinforcement of foundations, drainage etc. This work focuses on the factors which determine the level of long-term performance of these materials such as their mechanical and physical properties and physico-chemical ageing processes. (It includes contributions to an international seminar held at Saint-Remy-les-Chevreuse, France, in November 1986)




Porous Pavements


Book Description

Pavements are the most ubiquitous of all man-made structures, and they have an enormous impact on environmental quality. They are responsible for hydrocarbon pollutants, excess runoff, groundwater decline and the resulting local water shortages, temperature increases in the urban "heat island," and for the ability of trees to extend their roots in
