Pre-requisite qualifications

Undertaken a Level 1 Water Engineering and Geotechnics module (or equivalent)

Module replaces

CIVE2405 and CIVE2500

This module is not approved as a discovery module

Objectives

This module will build on the outcomes of the Level One modules involving Geotechnics and Water Engineering. As such the objectives relate to building on knowledge attained from that module.

The module objectives are:

(i) to further describe the factors that influence soil strength and to apply this understanding to ultimate load;

(ii) to discuss the concept of soil stiffness, and its application to deformation problems;

(iii) to develop an intuitive understanding of how soil will respond to load through the conceptual framework of Critical State Soil Mechanics;

(iv) to develop the equations of flow through porous media, and to apply them to both flow and consolidation problems;

(v) to develop analysis of energy/pressure loss in pipes in both laminar and turbulent flow;

(vi) to develop techniques for the analysis of piped (single and network) systems including reservoirs, pumps and valves etc;

(vii) to devliery the elementary aspects of water resources including requirements for both clean water and waste-water and its treatment;

(viii) to present initial open-channel flow concepts.

Learning outcomes
Students will:

(i) be able to apply their understanding of soil strength to ultimate load problems such as bearing capacity and slope stability;

(ii) be able to apply their understanding of soil stiffness to address deformation problems such as settlement of a structure;

(iii) be able to describe and use conceptual models such as Critical State Soil Mechanics to show how soil will respond to load;

(iv) be able to evaluate pore water pressures and flow volumes during steady state seepage, and estimate the effect of water flow on the rate of consolidation of clay soils;

(v) be able to discuss the concepts of fluid friction in pipes, and with reference to the Moody diagram describe how energy loss changes with Reynolds number and pipe material;

(vi) be able to analyse flow in pipes in series and in parallel as well as in pipe networks;

(vii) understand the demand and requirements for water, and the implication that this has on the infrastructure for both clean water and waste-water and its treatment;

(viii) understand the uniform flow analysis including Manning's equation and be able to calculate normal and critical depth in channels.
