Purpose

This layer was created for inclusion in the Victorian Australian Oil Spill Response Atlas. 

Supplemental Information

History: Field observations by DPI personnel and knowledge of the sites provided by coastal rangers were used to obtain estimates of the widths of river entrances and whether the entrance is subject to natural seasonal closures. Sites were selected on the basis of the possibility of an oil slick moving upstream in the watercourse in the event of an oil slick approaching the coastline. Sites are mainly perennial watercourses with an entrance width greater than 5 m except under periods of low river flows when the watercourse entrance may be blocked by sand. Related Documents: None

Missing Data

All of the coastline is covered by the layer. 

Attribute Quality

Attribution of all features has been validated by Department of Primary Industries (DPI), Victoria 

Positional Accuracy

Locations of the watercourse entrances were identified utilising the 1:25,000 coastline and hydrology layers as base layers, but the horizontal and vertical accuracy of the site locations have not been verified in the field. The point symbol represents the approximate centre of the entrance and sources of variations in precision will primarily relate to seasonal and yearly movements of the entrances due to changing river flows and this will particularly affect entrances identified as being intermittently open. 

Lineage

Description

Watercourse entrances were digitised utilising the digital 1:25,000 coastline and hydrology layers as a base map. Point locations for watercourses were placed in the approximate centre of its entrance. Attributes for each point were then added. 

Statement

Dataset Source: Information was derived from the 1:25,000 topographic hydrology layer, field observations by DPI personnel and information provided by DSE/DPI and Parks Victoria coastal rangers. Dataset Originality: Primary
