Flood estimation and storm water drainage for roads
|
Background
The Road Drainage Manual first published in 1981, has been fully updated revised and sections added by the South African National Roads Agency
Ltd (SANRAL) and published as Drainage Manual, 5th Edition - Fully revised
The manual has added sections on economics, subsurface drainage and diagrams and all other chapters are fully updated. In addition this
manual now falls in line with the new road classifications for South Africa that apply to all national, provincial and municipal authorities. The manual has also been expanded and is supported
by a suite of software packages.
Course objectives
The objectives of the course are to reflect principles, standards and procedures applicable to the hydraulic design and assessment of drainage problems and provide
guidance in solving drainage related problems. This will be achieved by reviewing the contents of the Drainage Manual
and reinforcing the understanding and application by problem solving.

Flood calculations and Free surface flow (HEC-RAS)
|
In past courses the focus was on extreme floods and design philosophies In this course it was decided to return to the basics and present a practical course on flood calculation methods.
The course includes:
- Flood calculation methods (Statistical, deterministic and empirical)
- Theoretical and practical problems in the determination of catchment rainfall
- Alternative methods for design flood estimation – empirical, statistical and process models.
Furthermore the course also focusses on the basic theory and practical applications of free surface flow. Aspects that are covered range from the basic theory of free surface flow, energy, momentum
and continuity as well as the use of the popular free software package HEC-RAS. The HEC-RAS River Analysis System Software is demonstrated in performing one-dimensional hydraulic calculations such as
steady and unsteady flow simulations. The capabilities of the software to analyse culverts and bridges, scouring at structures and dam break analysis are also demonstrated through practical
examples.

Transients in pipe systems
|
Transient flow assessment is a crucial part of the pressure class selection of pipes during the final design stage, preventing surge pressures, which in numerous cases results in pipe failures.
Foreseen and unforeseen operational circumstances can result in undesirable pressure conditions that should be analyzed for new pipelines, assessment of the upgrading of existing systems and
determining the influence and risk associated with planned operational changes. The use of the widely used Surge2000 computer software (www.kypipe.com) to analyze transients in pipe systems is
covered and problems solved in workshop sessions.

Water supply and waterborne sanitation systems
|
The general health of the population will be raised if people have access to basic water supply and sanitation. The vision of providing sanitation in South Africa as reflected in the Draft White Paper
on Water Services (DWAF, 2002) read as follows:
Water is Life, Sanitation is Dignity
1. All people living in South Africa have access to adequate, safe and affordable water and
sanitation services, practice safe sanitation and use water wisely.
2. Water supply and sanitation services are sustainable and are provided by effective and efficient institutions that are
accountable and responsive to those whom they serve.
3. Water is used wisely, sustainably and efficiently in order to promote economic growth and reduce poverty.
Water Supply and sanitation
has to be addressed in an integrated manner to achieve the vision for sanitation provision in South Africa. Conventional waterborne sanitation systems is usually perceived as the highest level of
service, but the lack of sustainable water in certain areas may warrant the consideration of alternative sanitation systems. The safe disposal of human excreta is vitally important in the control of
infectious and other communicable diseases and hence the construction of appropriate sanitation systems is paramount in contributing to the safe disposal of human excreta.
In the course the
theory and design practices of water supply and waterborne sewerage systems will be highlighted. Typical practical problems will be discussed and delegates will be guided through the solutions to a
number of problems. Guidelines for water supply in the rural environment and procedures to provide infrastructure and operational and maintenance frameworks will also be covered.
An
additional fourth day can also be attended where an introduction to the hydraulic modeling of water distribution systems will be covered, reflecting the basics of water distribution modeling and
reviewing the different components of water distribution systems. EPANET, which is public domain software, will be used for the modeling although the basic principles taught are applicable to any
water distribution modeling software.

Water distribution modelling
|
This course provides an introduction to the hydraulic modelling of water distribution systems. The basics of water distribution modelling are covered and all the different components of water
distribution systems are discussed.
EPANET is public domain software, which may be freely copied and distributed. EPANET is used as demonstration software although the basic principles taught are applicable to any water
distribution modelling software.
EPANET is a computer program that does hydraulic and water quality simulations of pressurized water distribution systems. It can perform single and extended-period simulations. EPANET tracks the flow
of water in each pipe, the pressure at each node, the height of water in each reservoir as well as the concentration of a chemical concentrations throughout the network during a simulation period.
The course covers the basic theory followed by practical computer sessions strengthening the material covered.
