In particular, 55 100% of students in the introductory hazards class (GLG111) started with "I don't know" responses (depending on the particular monitoring method), but in the post-survey, only 40% or fewer responded with "I don't know" for the same questions.
The hazard map prepared with five hazard classes viz.
Water hazard classes are based on the German General Administrative Regulation under the Federal Water Act on the Classification of Substances Hazardous to Water in Water Hazard Classes.
The resulting increasing landslide density with higher hazard classes indicates that the output map is reliable.
In the C and D hazard classes, both debris-flow occurrence and nonoccurrence cases are mixed up, not always indicating a result in which occurrences have higher hazard classes, and nonoccurrences fall into lower classes.
The hazard map was then divided by two scales, one with three classes for disaster managers and one with 10 detailed hazard classes for technical staff.
Irritant, corrosive and sensitising properties were based on classification of the respective product, environmental hazards on classification or on water hazard classes.
Thus, the rainfall criteria were set with the lower bound values of accumulated rainfall ranges for five hazard classes based on conservative hazard management.
Additionally, the BTV model requires a field survey to define vulnerability classes within the criteria 1 and 3, and numerical modeling for inundation hazard classes (criterion (2)).
Hazard classes A, B, C, and D have rainfall recurrence periods of 5 20, 20 50, 50 100 years, and over 100 years, respectively.
