The “major/minor” approach is being adopted as standard urban drainage design practice in many countries. Further to the normal primary drainage design for minor storms, this approach now requires management of inundation during extreme storms of return period fifty years or more. Surface flows then have to be investigated over an urban topography which is highly irregular and initially dry, and the transition from these conditions to major storm flows is difficult to analyse. The proposed modelling solution is based on the full integral hydraulic equations incorporating possible shock fronts. Wetting and drying simulation, careful channel resolution at low flows, and implicit solution methods with flat response properties are also important. Key points are illustrated by case studies.

Abstract An analytical tool is presented for the prediction of the effects of changes in tread pattern design on thick film wet traction performance. Results are reported for studies in which the analysis, implemented on a digital computer, was used to determine the effect of different tread geometry features, among these being the number, width, and lateral spacing of longitudinal grooves and the angle of zigzags in longitudinal grooves, on thick film wet traction. These results are shown to be in good agreement with experimental data appearing in the literature and are used to formulate guidelines for tread groove network design practice.

A new analytical expression is proposed for the prediction of the buckle propagation pressure for deepwater offshore pipelines. The expression accounts for the influences of the main factors involved, including the effects of material and geometrical nonlinearities. Predictions of the proposed expression are shown to be in good agreement with available experimental data, and valuable information is developed that can guide applications of the expression in design practice. In addition, a discussion is presented which outlines the derivation of the proposed expression.

Storm Drainage

Traditional design method for urban drainage systems is based on design storms and its major drawback is that frequencies of peak flows in the system are considered equal to frequencies of design storms. An alternative is to use historical storms with rainfall-runoff models to produce a series of possible flows in the system and their frequencies. The latter approach involves more computations and can be laborious for larger catchments. This paper considers ways to reduce the set of historical storms to be involved in design procedure and yet to lead to realistic flow frequencies. Frequencies obtained by rainfall-runoff simulation at an experimental catchment are compared with frequencies of observed peak flows in the system.

Water Sensitive Urban Design

 Water Sensitive Urban Design (WSUD) is a green approach to land development. Since introduced, the approach had been in practice in Peninsular Malaysia and Sabah, but not in favor yet in Sarawak. This study aims to identify Sarawak’s society awareness and acceptance on the WSUD approach. Surveys are being distributed to respondents with engineering and non-engineering background. Scenarios involving five WSUD approaches, namely: (i) Swale Underground Drain; (ii) Rainwater Underground Storage; (iii) Dry Detention Pond; (iv) Porous Pavement; and (v) Infiltration Trench, are being presented to the respondents. At the initial stage of the survey, only 29% of respondents with Civil Engineering background and 20% of respondent without Civil Engineering background recognize the concept but after being exposed to some WSUD approaches throughout the survey 99% of both respondents with and without Civil Engineering background agrees that the approach is beneficial and should be encouraged in Sarawak.

Drainage Design

Urban flooding in developing countries represents a growing threat to sustainable development efforts, yet the tools needed to study these infrastructure systems in data-scarce environments are woefully inadequate. This study seeks to propose a standardized approach and methods for mapping urban drainage systems in developing communities. The research draws on a case study from the Philippines, which sought to conduct rapid elevation surveys and drainage assessments employing open source geographical information system (GIS) tools. We develop a standardized procedure for digitizing drainage systems using OpenStreetMap and Field Papers, as well as discuss applications of this data for drainage design. The results contribute to a methodological framework that can be replicated in other similar developing communities where study of urban drainage is needed for sustainable development and disaster risk reduction efforts.
