OPEN (O): Breakage point where a recent (< 1 year) flood originated is still open, and has no signs of intervention/rehabilitation on the latest analysed images. May also indicate a portion of the river embankment where water overflows have recently occurred.
CLOSED with sandbags (Cs): Breakage point where a recent (< 2 years) flood originated and which has been fixed using sandbags. This point should also be considered as a POTENTIAL (P) river breakage, as sandbags are a temporary intervention subject to new floods.
CLOSED with heavy machinery (Cm): Breakage point where a recent (< 2 years) flood originated and that has been fixed using heavy machinery. Satellite images show soil heaping to reinforce the river embankment. This point should be considered a CLOSED river breakage as this type of intervention should prevent further flooding in the short to medium term.
CLOSED old (Co): Breakage point wherewhere an old (>2 years) flood originated. Signs of rehabilitation may or may not be observed. No flooding has been detected recently, so this point may be considered CLOSED as the situation is stable.
POTENTIAL (P): A point along the embankment where there is potential for flooding to occur. Clear indicators of flood potentiality, such as recent vegetation removal, embankment erosion, water spillage or other signs representing a potential embankment weakness have been identified. These indications are supported by DTM analysis, multi-temporal analysis and/or direct field observations.
