CONTEXT The engineering profession is changing rapidly, as are the needs of our undergraduates, which demands new approaches to learning and teaching. To become an engineer, students must combine sound theoretical knowledge with practical skills and experience. However, the growing trend in online education is creating many challenges for developin...
Article
In this article, a comprehensive literature review was conducted to investigate why urban water organisations are still lacking climate change adaptation in their water security management and planning, the key barriers and how they could be solved and enabled. In addition, urban water crises in the last decade have been examined to emphasise what...
Article
Advancing knowledge on how climate change impacts on water resources is considered a priority in the academic world. This paper studies the strategies adopted by urban water professionals in the tropical region of Queensland, Australia to minimise the impacts of climate change on the regional urban water supply network. In the recent past, the dry...

Many engineering academics interested in quality teaching and learning dabble with educational research. Some go further leaving their technical research field behind to embark head-long into what for many is an initially bewildering and conceptually challenging domain. Often peers perceive this transition as a crime (giving up on real engineering)...
Article
Flood modelling of a large basin like the Fitzroy is a difficult task due to its large catchment size, the long duration of flood events, the non-uniform spatial distribution of rainfall and a lack of required data for modelling purposes. This paper presents a systematic methodology for the flood modelling of the Fitzroy Basin using hydrologic and...
Article
Existence of soil pipes is reported in many collapsed slopes indicating their influences on landslide initiation. Flume model tests with different soil pipe configurations, (a) no pipe, (b) closed pipe and (c) open pipe, were conducted to understand the influence of soil pipes on slope stability during rainfall. Porewater pressures, discharges thro...
Article
Railway formation (embankments and cuttings) in Queensland are experiencing increased maintenance costs due to rainfall induced erosion and sedimentation problems. The erosion problems can be reduced by establishing grass cover on the steep slopes (batters). The objective of the research reported in this paper was to develop a continuous rainfall-r...
Article
A distributed 1D rainfall–runoff model is presented. It consists of the Saint Venant continuity and momentum equations for overland flow and a modified Green-Ampt model for the infiltration on railway embankment steep slopes. The model is applied to adjacent 10-m-wide erosion control experimental plots with different percentages of grass cover. A r...

Fitzroy Basin is the second largest catchment that drains to the coast in Australia. Fitzroy Basin is capable of producing severe flooding from tropical cyclone with heavy rainfall due its immense size and fan-like shape. Analysis shows that the historical peaks of different tributaries in different sub-basins of the Fitzroy River occurred in diffe...

This paper presents a large scale hydrological model for the Fitzroy Basin using the MIKE 11 NAM modelling system. This model simulates the rainfall runoff processes for the three different and interrelated storages which are surface storage, root zone storage and groundwater storage. The parameters of such model cannot be obtained directly from me...
Article
This paper investigates, using three-dimensional numerical modelling, the stability of curvature-based nine general hillslope types created by combining three profile and three lateral curvatures. The results show that the hillslopes with a concave profile curvature possess the highest pore-water pressure along the axial line, and hillslopes with a...
Article
Rainfall, temperature and evaporation govern the regional hydrologic cycle. There are several studies that have analysed the changing pattern of climatic variables at a global scale as well as regional scale in Australia. It is suggested from the recent studies that trend analysis of climatic variables should be performed at the catchment scale rat...
Article
Soil-pipes (porous pipes inside a hillslope) are often detected in collapsed slopes indicating their influence on slope failure processes. Only limited studies can be found regarding the impacts of soil-pipes on landslide mechanisms. Hillslope models prepared in a flume are experimented with different soil-pipe configurations: a) no pipe, b) closed...
Article
Soil pipes are considered to drain off water from a hillslope and play an important role in the subsurface runoff generation process, thus reducing the slope failure susceptibility. However, soil pipes are also often detected on the collapsed slope suggesting that they might act to induce slope instability. To examine how the soil pipes act on pore...
