Search Criteria Help

You can search for studies in a highlighted area on the map, in the catchment or local government area for a town or map point, or certain other (non-geospatial) metadata items.

Search by Bounding Box

Highlight the search area by either:

  • selecting the Bounding Box tool and drawing a rectangle on the map, or
  • entering North-South latitudes and East-West longitudes in the Bounds fields.

Click the Search button. The system displays all studies where the geographic centre of the study area is inside the highlighted area.

Search by Location and Region

Highlight a point on the map by either:

  • If you know the town name, start typing it in the Town/Location Lookup and select one of the autocomplete entries, or
  • selecting the Point tool and clicking on the map, or
  • entering latitude and longitude in the Location fields.

Set the Include Studies in same to Catchment or Local Government Area.

Click the Search button. The system displays all studies where the geographic centre of the study area is inside the same region as the highlighted point.

Advanced Options

Use the Advanced Options parameters to refine a map-based search, or on their own. All parameters are cumulative – the system will only return studies that meet every condition.

Search Fields

Fieldset Label Guidance
Bounding Box Bounds Enter north, south, east and west bounds to search an area, or we can set them for you when you draw a rectangle on the map.
Location and Region Location Lookup Enter the name of the town to lookup its co-ordinates and show it on the Map.
Latitude Enter the latitude for a point search. Both latitude and longitude must be input. Alternatively, the system sets the latitude when you use the Town/Location Lookup.
Longitude Enter the longitude for a point search. Both latitude and longitude must be input. Alternatively, the system sets the latitude when you use the Town/Location Lookup.
Include Studies in same Catchment Retrieve all the studies in the same Catchment as the location.
Include Studies in same Local Government Area Retrieve all the studies in the same Local Government Area as the location.
Advanced Options Study name (text search) Enter a word or phrase that is in the study name.
Year Study Completed From - To Enter a year range and search for studies published in the range.
River or Creek (text search) Enter the name of the waterway to search against the rivers, creeks and tributaries named in the study.
Town/Location (text search) Enter the name of the town to search against locations named in the study. Only towns identified in the report will be returned. To search for flood studies near a town or location, use the 'Bounding Box' or 'Location and Region' parameters.
State Select to view studies relevant to a state or territory. Studies may be relevant to more than one state or territory.
AFSID Each Flood Study has a unique Australian Flood Studies Identifier. If an AFSID is specified and the record exists, it will be shown in Results regardless of any other parameter entered. Multiple AFSID values may be entered using spaces, commas or tabs as delimiters.
Study Includes Content of Type

Select one or more entries to retrieve studies that include content of the selected types. Hold down the Control key and click on the relevant content type(s) to select or deselect item(s).

Use the ‘All of’ radio button to retrieve studies with all the selected information types.

Use the ‘Any of’ radio button to retrieve studies containing any of the selected information types.

Average Recurrence Intervals

Select Average Recurrence Intervals (ARIs) to retrieve studies that modelled the selected ARIs. Hold down the Control key and click on the relevant ARI(s) to select or deselect an ARI(s). 'Probable Maximum Flood/Precipitation' includes all studies which modelled a 'Probable Maximum Flood' or 'Probable Maximum Precipitation' scenario.

Use the ‘All of’ radio button to retrieve studies with every selected value.

Use the ‘Any of’ radio button to retrieve studies with at least one of the selected values.

Map Operations

Map operations icons

Use the Zoom In and Zoom Out buttons to focus on your area of interest.

Use the Full Extent button to return the map to the default extent.

Use the Previous Extent button to undo the previous zoom action.

Use the Pan button to navigate the map by clicking and dragging your mouse to move the map. Double click, or scroll your mouse wheel upwards, to zoom in. Scroll your mouse wheel downwards to zoom out. Hold shift, click and drag to form a box of interest to zoom in to.

Use the Zoom Box button then click and drag to form a box of interest to zoom in to.

Use the Bounding Box button to return all results in a bounding box of four points defined by its four corners. The corresponding coordinates will be displayed in the Bounds fields.

Use the Point Marker button to select a point on the map. The corresponding coordinates will be displayed in the Latitude and Longitude fields.

After performing a Search, use the Information button and click on a yellow Flood Study marker query to display information in the Details tab.

Use the Layers button to change the base layer and overlays of the map.

To expand or contract the right side pane click and drag the vertical bar that is to the immediate right of the map.

Map Overlays

The set of map overlays available depends on whether a search has been completed. Catchment and Local Government Area boundaries are always available, but other layers are dynamically set according to search results.

Overlay Meaning
Bounding Region Show boundary of the region searched. If the search involved a 'Bounding Box', the region displays as a rectangle. If the search involved a 'Bounding Region', the region displays as a Catchment or Local Government Area boundary. This overlay is only available when a geospatial search parameter is set.
Catchment Areas Show boundaries for Hydrological Regions as per Geofabric. (see Australian Hydrological Geospatial Fabric (Geofabric) for more information).
Centroid Show a red marker for the study currently displayed in the 'Detail' tab. This overlay is only available when a study is being displayed in the 'Detail' tab.
Local Government Areas Show boundaries for Local Government Areas as per the Australian Statistical Geography Standard (see Australian Statistical Geography Standard (ASGS): Volume 3 - Non ABS Structures, July 2011 for more information).
Related Catchment Areas Show boundaries of any Hydrological Regions that the study Centroid is contained in. This overlay is only available when a study is being displayed in the 'Detail' tab.
Related Local Government Areas Show boundaries of any Local Government Areas that the study Centroid is contained in. This overlay is only available when a study is being displayed in the 'Detail' tab.
Result Markers Show yellow markers for every study in the search result list. The markers represent the geographic centre of each study area. This overlay is only available when a search has been run and there are entries in the 'Results' tab.
