Integrating water with climate change adaptation plans
This policy brief, published by the UK Parliamentary Office of Science and Technology, argues that water resource management should not be overlooked in plans for climate change adaptation in Africa.Africa is vulnerable to climate change impacts which are, in large part, connected by water. Rainfall is uneven and unpredictable across different parts of the continent and varies dramatically by season. These variations can bring about floods and severe droughts that can last for years.The impacts of these weather...
Real-time flood stage forecasting by Variable Parameter Muskingum Stage hydrograph routing method
The application of a Variable Parameter Muskingum Stage (VPMS) hydrograph routing method for real-time flood forecasting at a river gauging site is demonstrated in this study. The forecast error is estimated using a two-parameter linear autoregressive model with its parameters updated at every routing time interval of 30 minutes at which the stage observations are made. This hydrometric data-based forecast model is applied for forecasting floods at the downstream end of a 15 km reach of the Tiber River in Central...
Company blends landclearing expertise, re-use of materials into successful business
Broad range of equipment and techniques helps Southwest Florida firm take landclearing to the next level. Landclearing, particularly that in which aesthetic considerations can come to bear, such as clearing for a golf course or housing tract development, is far from the `cut it all` process which the very name implies. Many successful landclearing professionals have honed the business into something of an art by selectively clearing, using existing foliage, and recycling or re-using cleared material. Doing so...

Problem Solver for water supply - Pollution incidents
Pollution in water supplies has always been a concern for water companies and with todays political climate the issue has never been more important. The threat of terrorism and the requirements of Homeland Security and similar initiatives around the world require that water companies maintain detailed plans for how to react swiftly in the event of a pollution incident, whether accidental or malicious, and that they are ready to implement the plans effectively. Although many of the counter-m...
Optimization a Mathematical Abstraction, or an Idea Whose Time Has Come?
Hydraulic models that use advanced modeling packages such as Infoworks are helping growing numbers of water supply planners and operators better understand how their networks operate and can operate in the future, under a wide range of conditions. One of the techniques modelers use for exploring how networks can operate better, a technique that is currently the subject of much discussion, is optimization – calculating the maximum or minimum value of a particular function, such as a cost function, and determining...
The Need for a Total View of Water Networks
The water industry is not short of software offerings, and so the arguments in favour of yet another software program had better be very good indeed. In this article we examine how one very significant community of users – operations managers, engineers and planners - have largely had their specific needs overlooked; we identify the type of system needed to fulfil their requirements and the operational and commercial benefits that might flow from its use. There are currently four types of software in widespread...
Improving Service Levels and Reducing Costs - The Business Case for Network Modelling
