Debris Flow Disaster

This report supports geotourism as an effective method of disaster storytelling, based on the lessons learned during and after the 2013 Izu-Oshima Island Debris Flow Disaster. Geotourism can provide a geological explanation to visitors as to why the disaster occurred in Izu-Oshima island, while also allowing a vital opportunity to help local people impacted by the disaster make sense of their catastrophic experiences. By doing so, individuals involved in geotourism can share a reverence and respect for the living Earth, which enables us to move forward even after experiencing a catastrophic disaster. This function is very similar to what Disaster Storytelling has.

Debris Flow Disaster

The deposition prediction of debris flow hazardous area is very important for organizing and implementing debris flow disaster prevention and reduction. This paper selected the data base from laboratory experiments and applied the multiple regression statistical method to establish a series of empirical calculation models for delimiting the debris flow hazardous areas on the alluvial fan. The empirical models for predicting the maximum deposition length (Lc), the maximum deposition width (Bmax) and the maximum deposition thichness (Z0) under the condition of different debris flow volumes (V), densities (rm) and slopes of accumulation area (θd) were establised. And the verification results indicated that the established models can predict the debris flow hazards area with the average accuracy of 86%.

Debris Flow Disaster

This paper presents a Debris Flow Disaster Faster-than-early Forecast System (DFS) with wireless sensor networks. Debris flows carrying saturated solid materials in water flowing downslope often cause severe damage to the lives and properties in their path. Faster-than-early or faster-than-real-time forecasts are imperative to save lives and reduce damage. This paper presents a novel multi-sensor networks for monitoring debris flows. The main idea is to let these sensors drift with the debris flow, to collect flow information as they move along, and to transmit the collected data to base stations in real time. The Raw data are sent to the cloud processing center from the base station. And the processed data and the video of the debris flow are display on the remote PC. The design of the system address many challenging issues, including cost, deployment efforts, and fast reaction.

Debris Flow Disaster

Rainfall-triggered debris flow has caused multiple impacts to the environment. It. is regarded as the most severe secondary hazards of volcanic eruption. However, limited access to the active volcano slope restricts the ground rain measurement as well as the direct delivery of risk information. In this study, an integrated information system is proposed for volcanic-related disaster mitigation under the framework of X-Plore/X-band Polarimetric Radar for Prevention of Water Disaster. In the first part, the acquisition and processing of high-resolution X-band dual polarimetric weather/X-MP radar data in real-time scheme for demonstrating the disaster-prone region are described. The second part presents the design of rainfall resource database and extensive maps coverage of predicted hazard information in GIS web-based platform accessible both using internet and offline. The proposed platform would be useful for communicating the disaster risk prediction based on weather radar in operational setting.

Debris Flow Disaster

This paper addresses a debris flow disaster in Yingxiu town after the Wenchuan earthquake. Through site investigation and data review, the geography and geological environment of the basin and the development, formation conditions and activity characteristics of the debris flow in the basin are analyzed. Calculate and analyze the characteristics of the debris flow, such as gravity, flow velocity and impact force. According to the management idea of combination of blocking and discharging, this paper proposes to arrange three blocking dams in the main ditch, construct drainage gullies in the downstream accumulation section, and prevent and control the aqueduct in the intersection of the main ditch and the G213 national road, which will be similar to the earthquake in the future. It is provided as a reference for research and prevention of the debris flow.

Design Challenges

Interactive architecture bridges in itself two design traditions, i.e. design of interactive systems on the one hand, and architecture as the tradition of designing our built environment on the other hand. This article reports from our ongoing project focused on the design and implementation of an interactive environment for public use. The article describes the project, reviews and outlines the main design challenges as pinpointed in the literature on interactive architecture, and describes the practical challenges identified in this particular project. This article then presents the participatory design approach adopted in this project to overcome these challenges, and describes and analysis the methodological implications from this project. These implications include the lessons learned from the coordination of a geographically distributed design team, “role gliding” as the reinterpretation of the designers as users in the participatory design process, and a shift from communities of practices to mixtures of professions.
