Bases: Exception

Exception raised when no tide data is to be used for the BG-Flood model.

floodresilience.dynamic_boundary_conditions.tide.tide_query_location.get_regional_council_clipped_from_db(engine: sqlalchemy.engine.Engine, catchment_area: geopandas.GeoDataFrame) → geopandas.GeoDataFrame

Retrieve regional council clipped data from the database based on the catchment area.

Parameters:

  • engine (Engine) – The engine used to connect to the database.

  • catchment_area (gpd.GeoDataFrame) – A GeoDataFrame representing the catchment area.

Returns:

A GeoDataFrame containing the regional council clipped data for the catchment area.

Return type:

gpd.GeoDataFrame

floodresilience.dynamic_boundary_conditions.tide.tide_query_location.get_nz_coastline_from_db(engine: sqlalchemy.engine.Engine, catchment_area: geopandas.GeoDataFrame, distance_km: int = 1) → geopandas.GeoDataFrame

Retrieve the New Zealand coastline data within a specified distance of the catchment area from the database.

Parameters:

  • engine (Engine) – The engine used to connect to the database.

  • catchment_area (gpd.GeoDataFrame) – A GeoDataFrame representing the catchment area.

  • distance_km (int = 1) – Distance in kilometers used to buffer the catchment area for coastline retrieval. Default is 1 kilometer.

Returns:

A GeoDataFrame containing the New Zealand coastline data within the specified distance of the catchment area.

Return type:

gpd.GeoDataFrame

floodresilience.dynamic_boundary_conditions.tide.tide_query_location.get_catchment_boundary_info(catchment_area: geopandas.GeoDataFrame) → geopandas.GeoDataFrame

Get information about the boundary segments of the catchment area.

Parameters:

catchment_area (gpd.GeoDataFrame) – A GeoDataFrame representing the catchment area.

Returns:

A GeoDataFrame containing information about the boundary segments of the catchment area.

Return type:

gpd.GeoDataFrame

Raises:

ValueError – If the position of a catchment boundary line cannot be identified.

floodresilience.dynamic_boundary_conditions.tide.tide_query_location.get_catchment_boundary_lines(catchment_area: geopandas.GeoDataFrame) → geopandas.GeoDataFrame

Get the boundary lines of the catchment area.

Parameters:

catchment_area (gpd.GeoDataFrame) – A GeoDataFrame representing the catchment area.

Returns:

A GeoDataFrame containing the boundary lines of the catchment area.

Return type:

gpd.GeoDataFrame

floodresilience.dynamic_boundary_conditions.tide.tide_query_location.get_catchment_boundary_centroids(catchment_area: geopandas.GeoDataFrame) → geopandas.GeoDataFrame

Get the centroids of the boundary lines of the catchment area.

Parameters:

catchment_area (gpd.GeoDataFrame) – A GeoDataFrame representing the catchment area.

Returns:

A GeoDataFrame containing the centroids of the boundary lines of the catchment area.

Return type:

gpd.GeoDataFrame

floodresilience.dynamic_boundary_conditions.tide.tide_query_location.get_non_intersection_centroid_position(catchment_area: geopandas.GeoDataFrame, non_intersection_area: geopandas.GeoDataFrame) → geopandas.GeoDataFrame

Determine the positions of non-intersection centroid points relative to the boundary lines of the catchment area.

Parameters:

  • catchment_area (gpd.GeoDataFrame) – A GeoDataFrame representing the catchment area.

  • non_intersection_area (gpd.GeoDataFrame) – A GeoDataFrame representing the non-intersection area.

Returns:

A GeoDataFrame containing the positions of non-intersection centroid points relative to the catchment boundary lines. The GeoDataFrame includes the ‘position’ column denoting the relative position and the ‘geometry’ column representing the centroid points of the non-intersection areas.

Return type:

gpd.GeoDataFrame

floodresilience.dynamic_boundary_conditions.tide.tide_query_location.get_tide_query_locations(engine: sqlalchemy.engine.Engine, catchment_area: geopandas.GeoDataFrame, distance_km: int = 1) → geopandas.GeoDataFrame

Parameters:

  • engine (Engine) – The engine used to connect to the database.

  • catchment_area (gpd.GeoDataFrame) – A GeoDataFrame representing the catchment area.

  • distance_km (int = 1) – Distance in kilometers used to buffer the catchment area for coastline retrieval. Default is 1 kilometer.

Returns:
