Processing Algorithm: Create breaches at fixed interval

[leendertvanwolfswinkel]

Algorithm description Algorithm should follow roughly the following logic:

• Create points at specified interval along channel
• For each created point, find the nearest point on this channel's exchange_line
• Create a potential_breach from the channel to the exchange_line
• Add output breach lines as new features to output breach layer, including the channel_id, material, exchange_level and max_breach_depth

Parameters

Name	Description	Data type	Allow using only selected features
Channels	Channels where the breach line starts	Vector layer (line geometry)	Yes
Interval [m]	A breach will be created along the channel at the specified interval	Float ( > 0)	-
Material	Material (sand or clay) of the dike that will be breached	String / enum ("Sand" or "Clay")	-
Exchange level	Crest level of the dike	Float	-
Max breach depth	Maximum depth of breach relative to exchange level	Float (>0)	-
Output potential_breach layer	Vector layer to which the output breaches will be appended	Vector layer (line geometry)	-

Cases that should be handled

• Parameter layers have different CRS
• Parameter layers have non-projected CRS (units not in m)
• Selection contains no channels
• Output potential_breach layer does not have the correct geometry or attributes
