Governing today is far from simple. The pressures caused by ongoing budget constraints, exacerbated by the subprime mortgage crisis and the resulting rise in foreclosures, plus a contracting credit market are compounded by major challenges which include insufficient capacity within local government resulting in poor operation and maintenance of infrastructure. This manifests within municipalities as ineffective utilisation of municipal resources, non-compliance with environmental legislation, little or no service delivery, and potential hazardous environmental and human health impacts. The management of water, one vital aspect of the environment, is consequently being neglected in most regions of South Africa. There is an urgent need today to protect our scarce water resources and, at the same time, properly manage storm water and waste water for the benefit of the environment and the protection of communities.
Pattern recognition is hard-wired into our brains. Unfortunately, it seems that most civil engineers have forgotten how to apply it to solve complex problems. This article gives some examples of where pattern recognition led to the solution of problems, and the examples date back to biblical times.
The South African National Committee on Large Dams (SANCOLD) changed its governance structure in September 2008 to be more democratic and representative of the broader dam industry. SANCOLD activities cover both 'large' and 'small' dams, as well as tailings dams. SANCOLD membership will provide organisations and individuals with various opportunities for interaction with other people involved in water resources management. Dams play a very important role in the development and management of South Africa's water resources, and future dam construction is planned as part of the general infrastructure development in South Africa.
SANCOLD is pleased to announce that the South African Register of Large Dams can now be downloaded from the SANCOLD website (www.sancold.org.za). The Register is given in the form of an Excel spreadsheet. This provides the facility of being able to sort the information easily and to draw interesting conclusions. This Register is part of the larger ICOLD Register of World Dams which contains information on about 50 000 large dams.
Port Elizabeth, like so many South African towns, suffered severe water shortages as it developed during the 19th century. It was the duty of John Gamble, the Colonial Hydraulic Engineer (Past Master 18), to sort out such problems, and for PE his solution was to build a weir on the Van Stadens River, linked to the town by a 30-mile long pipeline. John Hamilton Wicksteed, AMICE , was selected for the post of Resident Engineer and arrived in Algoa Bay on 29 December 1877 aboard the vessel Edinburgh Castle.
Port Elizabeth, in common with many other South African cities, has experienced periodic crises in the supply of potable water. Over the years the problems have been addressed by engineers with the result that, while the city has sometimes been thirsty, it has never actually been dry.

Online media and technology has grown in leaps and bounds in the last decade. Although not so popular ten years ago, online media usage has also been growing steadily in the engineering industry. In this article we take a brief look at how this trend is affecting the profession in terms of effective communication.
