Global trends have seen a strong push for more effective participatory planning in democratic societies. Effective communication and universal accessibility are underpinning principles of successful participatory planning. Virtual environments (VEs) have proven to significantly improve public understanding of 3D planning data. This paper will evaluate multi-touch screens as a 3D VE navigation device for the general public in a participatory planning context. The interactivity of multi-touch technology may better engage participants and improve their understanding of planning policies and proposed projects. With the recent proliferation of multi-touch technology in the personal device market, there is great potential for expanding accessibility of participatory planning applications.

“…By using digital hydrodynamic models to calculate the water depth and flow velocity, flood evolution and inundated areas could be simulated and displayed in a 3D virtual environment, thus enhancing decision-makers', the public's, and other stakeholders' awareness of floods. It will also promote scientific management of flood disasters [6][7][8][9]. Although the effect of visualization (such as rainfall and rollback waves) in these studies is reasonably well presented [8], most of them use simulation software or animation technology to show the effects of floods and inundated areas at different times [9].…”

“…Hydrodynamic models are very complicated and involve large amounts of data [6][7][8][9]. The application value of a hydrodynamic model is affected by the following factors: (a) The availability, timeliness, and resolution of basic data pertaining to the river channel and its surroundings; (b) the effect of the visualization of the computation results; and (c) the extent to which the hydrodynamic models and the business system are integrated.…”

Dynamic visual simulation of flood risk is crucial for scientific and intelligent emergency management of flood disasters, in which data quality, availability, visualization, and interoperability are important. Here, a seamless integration of a spatio-temporal Geographic Information System (GIS) with one-dimensional (1D) and two-dimensional (2D) hydrodynamic models is achieved for data flow, calculation processes, operation flow, and system functions. Oblique photography-based three-dimensional (3D) modeling technology is used to quickly build a 3D model of the study area (including the hydraulic engineering facilities). A multisource spatio-temporal data platform for dynamically simulating flood risk was built based on the digital earth platform. Using the spatio-temporal computation framework, a dynamic visual simulation and decision support system for flood risk management was developed for the Xiashan Reservoir. The integration method proposed here was verified using flood simulation calculations, dynamic visual simulations, and downstream river channel and dam-break flood simulations. The results show that the proposed methods greatly improve the efficiency of flood risk simulation and decision support. The methods and system put forward in this study can be applied to flood risk simulations and practical management.

“…Multi-dimensional visualization techniques, which include 3-D and 4-D analyses, enable better understanding, access and presentation of the integrated information from different type of sources (Cross et al 2005). 3-D modelling techniques have been widely used to display volumetric characteristics of a given structure, such as surface mapping, surface hydrology, and groundwater levels (Glynn et al 2011); the piezometer and water levels (Spencer et al 2010) and water surface variations during flood (Lai et al 2011). In addition, there are various studies about the modelling of the geometric surfaces and 3D layers that carry the lithological and hydraulic level characteristics (Dominguez-Acosta et al 2004) and associated functionalities, such as saving, rotation, zoom, cut and slice (Xi-juan et al 2010).…”

Visualization requirements of engineers for risk assessment of embankment dams

et al. 2015

View full text Add to dashboard Cite

Background: Aging infrastructure in the US has gained quite a bit of attention in the past decade. Being one type of a critical infrastructure, embankment dams in the US require significant investment to upgrade the deteriorated parts. Due to limited budgets, understanding the behavior of structures over time through risk assessment is essential to prioritize dams. During the risk assessment for embankment dams, engineers utilize current and historical data from the design, construction, and operation phases of these structures. The challenge is that during risk assessment, various engineers from different disciplines (e.g., geotechnical, hydraulics) come together, and how they would like to visualize the available datasets changes based on the discipline-specific analyses they need to perform. The objective of this research study is to understand the discipline-specific visualization needs of engineers from US Army Corps of Engineers (USACE) who are involved in risk assessment of embankment dams when they deal with large set of data accumulated since the inception of dams. Methods: The requirements were identified through a three-phased research approach including interviews with engineers who are regularly involved in risk assessment processes, a card game and review of standards and published work on risk assessment of embankment dams. Results: This paper provides the findings of research conducted with engineers coming from different disciplines within USACE. Findings comprise discipline-specific visualization requirements of engineers for viewing large datasets, containing static data (e.g. design information) and time-series data (e.g. piezometer data, monument measurements etc.), accumulated since the inception of dams.
