2010 Index of Stream Condition - Bank Condition Reach Summary Table

Abstract:
The ISC2010_BANK_CONDITION_R table is the Statistical Summary table for the Bank Condition Metric at the Reach level. The Bank Condition Metric is an assessment of the proportion of the bank face that is eroding above expected rates.
The ISC2010_BANK_CONDITION_R table is designed to JOIN to the ISC2010_RIVER_CENTRELINES_R feature class.
River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC). The Department of Environment and Primary Industries (DEPI) developed a methodology to assess the Physical Form and Riparian Vegetation components of the ISC using remote sensing data, specifically LIDAR and aerial photography.
A State Wide mapping project was undertaken in 2010-13 to accurately map the Physical Form and Riparian Vegetation metrics of the ISC . Other ISC metrics were not assessed in the project and were derived from other sources.
The Physical Form and Riparian Vegetation Metric products are a combination of mapped Vector and Raster data as well as Tabular Summary Statistics about the mapped features. In the context of the project, the term Metrics is used to refer to both the mapped features and the summary statistics.
Remote sensing data used includes 15cm true colour and infra-red aerial photography and four return multi-pulse LiDAR data. This source data was used to derive a variety of Raster data sets including Digital Terrain Models, Slope, Vegetation Height and Vegetation Cover. The Digital Terrain and Slope rasters were used to map Physical Form metrics including Stream Bed, Top of Bank and River Centre Lines while the Vegetation Height and Cover rasters were used to map the Riparian Vegetation metrics.
The Project Report "Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping" describes the remote sensing and mapping approach used to create this data set.
Every Reach has had attributes summarised and a Score determined.

The ISC2010_BANK_CONDITION_R table is the Statistical Summary table for the Bank Condition Metric at the Reach level. The Bank Condition Metric is an assessment of the proportion of the bank face that is eroding above expected rates.

The Department of Environment and Primary Industries (DEPI) developed a methodology to assess the Physical Form and Riparian Vegetation components of the ISC using remote sensing data, specifically LIDAR and aerial photography.
A State Wide mapping project was undertaken in 2010-13 to accurately map the Physical Form and Riparian Vegetation metrics of the ISC . Other ISC metrics were not assessed in the project and were derived from other sources.

This source data was used to derive a variety of Raster data sets including Digital Terrain Models, Slope, Vegetation Height and Vegetation Cover. The Digital Terrain and Slope rasters were used to map Physical Form metrics including Stream Bed, Top of Bank and River Centre Lines while the Vegetation Height and Cover rasters were used to map the Riparian Vegetation metrics.
The Project Report "Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping" describes the remote sensing and mapping approach used to create this data set.
The purpose of the Bank_Condition_R table is to summarise the set of Bank Condition attributes at the Reach level and to store a Bank Condition Score for every Reach. Bank Condition is assessed on the proportion of the bank face that is eroding above expected rates.
The Reach Summary Table is designed to facilitate a JOIN with the ISC2010_RIVER_CENTRELINES_R feature class.

The UniqueID that describes the Basin and Reach Number for each Reach is complete for every Reach. Every Reach has been summarised and had a Score determined.
Logical Consistency:
Every Reach is represented in the table. The ISC2010_BANK_CONDITION_R table is designed to JOIN to the ISC2010_RIVER_CENTRELINES_R feature class.
Data Source:
Dataset Source: The Bank Condition Summary table was programatically generated based on analysis of River Centrelines, Slope and Stream Bed Type and Confinement attributes. Inputs includes Channel Transects, Bankfull Width and Streambed Width.
