“…Perhaps it is the case that while personalized maps helped respondents understand their risk susceptibility, personalized maps cannot work alone in influencing other important factors such as perceptions of risk, behavioural intention, crisis efficacy, message understanding or trust in the source. Indeed, higher specificity warning messages help increase public response (Lindell & Perry, 1987), and graphics without supporting text are likely to be misinterpreted (Dallo et al., 2020). The findings of this study suggest maps with supporting text (but unspecific to the user's location) may be misinterpreted as well.…”

Emergency alerts are typically sent through mobile devices and email and are a means by which to notify students of threats or hazards on campus. Alerts that include maps help illustrate the significance of a threat and improve understanding when designed correctly. This study of a college campus examines how maps can clarify who should take protective action by specifying the location of the threat in relation to the user, and whether maps affect risk perception, intended action, and trust in the message source. Results indicate a significant difference in perceptions of risk susceptibility between participants exposed to a long‐distance map, a short‐distance map, and no map, and participants exposed to the shooting condition reported significantly higher measures of negative emotions, risk susceptibility, risk severity, and behavioural intention. Findings indicate that while personalized maps improve risk susceptibility, they cannot work alone in affecting other message response factors and may be most useful when paired with highly specific warning messages. The results of this study are useful to practitioners developing or improving emergency alert systems.

Abstract. In the past few decades, various natural hazards have occurred in Laos. To lower the consequences and losses caused by hazardous events, it is important to understand the magnitude of each hazard and the potential impact area. The main objective of this study was to propose a new approach to integrating hazard maps to detect hazardous areas on a national scale, for which area-limited data are available. The integrated hazard maps were based on a merging of five hazard maps: floods, land use changes, landslides, climate change impacts on floods, and climate change impacts on landslides. The integrated hazard map consists of six maps under three representative concentration pathway (RCP) scenarios and two time periods (near future and far future). The analytical hierarchy process (AHP) was used as a tool to combine the different hazard maps into an integrated hazard map. From the results, comparing the increase in the very high hazard area between the integrated hazard maps of the far future under the RCP2.6 and RCP4.5 scenarios, Khammouan Province has the highest increase (16.45 %). Additionally, the very high hazard area in Khammouan Province increased by approximately 12.47 % between the integrated hazard maps under the RCP4.5 and RCP8.5 scenarios of the far future. The integrated hazard maps can pinpoint the dangerous area through the whole country, and the map can be used as primary data for selected future development areas. There are some limitations of the AHP methodology, which supposes linear independence of alternatives and criteria.

“…While there is scientific interest in identifying more robust ways to accurately describe a hydraulic system with respect to reference hydrologic features, there is equal practical interest in demonstrating the advantages of concise power law relationships in modern hydrologic applications such as rating curves estimation [20]; flood forecasting [10,13] and flood warning [31][32][33]. These advantages are highlighted in the discussion and include that they:…”

Hydraulic relationships are important for water resource management, hazard prediction, and modelling. Since Leopold first identified power law expressions that could relate streamflow to top-width, depth, and velocity, hydrologists have been estimating ‘At-a-station Hydraulic Geometries’ (AHG) to describe average flow hydraulics. As the amount of data, data sources, and application needs increase, the ability to apply, integrate and compare disparate and often noisy data is critical for applications ranging from reach to continental scales. However, even with quality data, the standard practice of solving each AHG relationship independently can lead to solutions that fail to conserve mass. The challenge addressed here is how to extend the physical properties of the AHG relations, while improving the way they are hydrologically addressed and fit. We present a framework for minimizing error while ensuring mass conservation at reach - or hydrologic Feature - scale geometries’(FHG) that complies with current state-of-the-practice conceptual and logical models. Through this framework, FHG relations are fit for the United States Geological Survey’s (USGS) Rating Curve database, the USGS HYDRoacoustic dataset in support of the Surface Water Oceanographic Topography satellite mission (HYDRoSWOT), and the hydraulic property tables produced as part of the NOAA/Oakridge Continental Flood Inundation Mapping framework. The paper describes and demonstrates the accuracy, interoperability, and application of these relationships to flood modelling and presents this framework in an R package.
