This data layer comes from information recorded at the Department of Public Security's Operations Directorate (MSP) during winter temperatures or spring floods. The compilation was carried out from digital documents, papers, event reports or situation reports. The database also contains field observations made by municipal stakeholders grouped into river monitoring committees. These committees are set up and coordinated by the regional directorates of the MSP. Field observation is the collection of qualitative or quantitative data on the state of the river at a specific time. The level of the river can, when the situation applies, be measured using a limnimetric scale or assessed using a geographic coordinate system, as well as its trend (upward, stable, or downward). General information characterizing the ice cover may also be recorded by the observer. The information in the database is consistent with the Canadian Common Alert Protocol Profile (PC-PAC). The PC-PAC is a set of rules and controlled values that support the translation and composition of a message to facilitate its sending by various means and from different sources. The PC-PAC formats used are as follows: DEGREE OF SEVERITY The level of severity of the event based on the injury to life of persons or damage to property. The degree of severity of observations on past events can therefore be estimated from the consequences that were recorded at the time of the events. For field observations by river committees, the degree of severity is generally estimated directly by the observer. The definitions are as follows: Extreme: an extraordinary threat to life or property. Important: a significant threat to life or property. Moderate: possible threat to life or property. Minor: low threat to life or property. Normal: no threat to life or property. Unknown: gravity unknown. EMERGENCY The level of urgency is determined based on the reactive measures that need to be taken in response to the current situation. The definitions are as follows: Immediate: a reactive action should be taken immediately. Planned: a reactive action is to be taken soon (within the next hour). Future: reactive action should be taken in the near future. Past: reactive measurement is no longer necessary. Unknown: emergency unknown. STATE The state concerns the context of the observation, real or simulated. Current: information about a real event or situation. Purpose: To obtain a global portrait of the situation with respect to ice jam flooding problems in order to estimate the risk of flooding along river sections subject to this problem. Locate the ice jams recorded on Quebec's waterways geographically. Characterize each listed case according to the severity level as defined in the PC-CAP joint alert protocol.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
