This module builds on the Stage 2 Hydraulics I (CVEN20130) module in which foundation material relating to fluid definitions, properties, application of the fundamental fluid principles (continuity, energy and momentum) were presented for steady flow closed conduit and open channel hydraulic systems. It is essential that this material is fully understood and retained at the commencement of the Hydraulics II module. The module itself will take place in the Spring trimester and will consist of 36 lectures (3 per week), 2 laboratory exercises, 4 tutorials, 2 in-class tests and an end of trimester examination. The course is broadly split between closed conduit (pipe) and open channel (rivers and streams) flow and will also present the principles of physical similarity in hydraulic systems in which experimental results from small scale models are applied to other conditions.

The closed conduit analysis in this module develops the theory presented in Hydraulics I for single pipe systems to parallel and series systems and also to more complex branched and loop-type pipe networks. Energy is lost through friction and local losses in pipe systems but mechanical energy through hydrodynamic machines can overcome these losses. Hydrodynamic machinery (pumps) are investigated for a full range of pipe systems. The open channel flow component of Hydraulics I studied steady-uniform flow conditions in simple channels. The open channel flow component of Hydraulics II builds on this to include non-uniform flows that are both gradually and rapidly varied. Energy and momentum principles are applied in this analysis and the 'special' case of hydraulic jumps are analysed. Water surface GVF profiling using direct and standard step methods is presented and this OCF analysis is extended to river modelling (HEC-RAS). More complex compound channel geometries where floodplains are inundated present different challenges for engineers and these are presented and analysed.

The concept of suntainability features throughout the module. The relationship of the module content to the UN SDGs is presented at the outset of the course and as students work through the the different course components, the relevence of that material to SDGs (particularly, SDG 6, 9, 11 and 14) is outlined.

About this Module

Learning Outcomes:

On completion of this module, students should be able to: (1) calculate flows and pressures in single pipe systems and in more complex pipe networks; (2) design pump-pipeline systems to meet flow and pressure requirements; (3) understand the impacts of aging on pipe systems and develop solutions to remediate loss of performance that results from possible age related increased friction; (4) re-design existing pipe systems to accommodate increasing demand etc.; (5) identify and classify steady, unsteady and uniform and non-uniform open channel flows; (6) apply both the energy and momentum equations in combination with continuity and friction to solve problems in rapidly varied open channel flows; (7) derive the gradual varied flow equation from first principles and extend to rectangular and wide channels; (8) solve gradually varied flow problems by direct and standard step methods; (9) analyse variations in resistance along the wetted perimeters of simple and compound channels; (10) plan and conduct experiments, analyse and interpret the results and write up your findings in a coherent and logical manner; and (11) in the context of (1) to (10) above, understand sustainability concepts and the relevance of the UN SDGs to the course content.

Approaches to Teaching and Learning:
Learning approaches in this module will be varied and will include lectures (with complete course notes being available at the beginning of the module) supported by active learning interventions. These interventions will require student input (individually and in small learning communities) such that a social and collaborative learning environment is created. Class discussions on different topics will be supported by class polls (using polleverywhere). Theoretical components of the module will be presented in lectures and problems relating to pipe and open channel flow will be introduced (in lectures and tutorials) through enquiry and problem-based learning. Argumentation and debate will be encouraged throughout. The learning approaches will promote the development of critical thinking skills and dispositions in students. Laboratory exercises will be used to further explain the theory and concepts of lectures and to provide students with first-hand experience of laboratory measuring. Laboratory reports will be submitted for assessment.
