This data set contains shape files representing the locations and results of radon(222Rn) and helium-4(4He) surface water sampling from in-stream reaches and pools, as well as off-channel wetlands of ... morethe Fitzroy and Margaret rivers Western Australia. The data provides information about the spatial nature of connectivity between groundwater and surface water along approximately 300 km of the Fitzroy River and 80 km of the Margaret River. The data was collected via helicopter in June 2017. The purpose of the data set is to graphically communicate the results of 222Rn and 4He sampling in surface water and how that relates to spatial changes in groundwater – surface water connectivity.less

(2018) and (iii) field measurements collated from various hydrogeological investigation reports for Indigenous communities and pastoral station groundwater supplies. In this data set, hydraulic head values from 143 bore sites were identified as being suitable to interpolate a standing water level surface for the Grant Group and Poole Sandstone aquifers. ArcGIS was used to interpolate point hydraulic head data into a continuous standing water level surface for the entire extent of the Grant Group and Poole Sandstone within the Fitzroy catchment and some surrounding areas. The purpose of the standing water level surface is to map and understand the spatial changes in depth to hydraulic head which can be related to the cost of pumping the resource.less

The shape files are symbolised to represent different categories of the likelihood of groundwater inflow (i.e. low, medium or high) and are based on the results and interpretation of a longitudinal surface water environmental tracer and chemistry sampling survey. The purpose of the data set is to map the spatial occurrence and likelihood of groundwater inflow to reaches of the Fitzroy and Margaret rivers in Western Australia, to graphically communicate groundwater – surface water connectivity.less
Dry-season wetlands data show the average value derived from each season’s maximum number of consecutive days where surface water has been identified during the dry seasons from 1988 to 2016 from Land... moresat imagery. This dataset was created for the CSIRO Northern Australia Water Resource Assessment (NAWRA) project. These data are maps of dry-season wetlands derived from the Landsat archive from 1988 to 2016 (i.e. 29 years). The Landsat archive data were extracted from Geoscience Australia’s Surface Reflectance NBAR product available on the National Computing Infrastructure. The method used to derive the surface water maps is described in the NAWRA technical report (Sims et al., 2016). The data are provided as average number (from the 29 years of Landsat data) of the maximum consecutive days of inundation during each dry season. The average number of maximum consecutive days is then converted into shape files: one showing all pixels containing an average value of 50 or more maximum consecutive days of inundation from all the dry seasons; the other showing all pixels containing an average value of 100 or more maximum consecutive days of inundation from all the dry seasons.

This dataset was created for the CSIRO Northern Australia Water Resource Assessment (NAWRA) project. These data are maps of persistent waterholes derived from the Landsat archive from 1988 to 2015 (i.e. 27 years). The Landsat archive data were extracted from Geoscience Australia’s Surface Reflectance NBAR product available on the National Computing Infrastructure. The method used to derive the persistent waterhole maps is described in the NAWRA technical report (Sims et al., 2016). The data are provided as percentage of (valid) years that a pixel contained water at the end of the dry season. A percent value of 100 means that the pixel was wet at the end of every dry season for all available years. Those pixels containing water in them at the end of the dry season for at least 90% of the years are provided as shape files. More information is provided in the supporting attachment.less

This dataset was created for the CSIRO Northern Australia Water Resource Assessment (NAWRA) project. This dataset uses another dataset (also available on the Data Access Portal titled ‘Persistent waterholes derived from Landsat archive for NAWRA’), where waterholes were mapped at the end of each dry season (based on available cloud-free Landsat scenes) using a Normalised Difference Water Index derived from Landsat imagery. This method is described in Sims et al. (2016) and only looks at the persistence of water within each pixel through time. This dataset allows for the fact that a waterhole can vary in shape and local location through time, by providing the percentage of years that at least one water pixel is identified within along-stream segments at the end of each dry season. Further information is provided as a supported attachment. less

This data provides improved land evaluation information to identify opportunities and promote detailed investigation for a range of sustainable development options and was created within the ‘Land suitability’ activity of the Northern Australia Water Resource Assessment (NAWRA). There are five land suitability classes coded 1-5. 1 – Highly suitable land with negligible limitations 2 – Suitable land with minor limitations 3 – Moderately suitable land with considerable limitations 4 – Currently unsuitable land with severe limitations 5 – Unsuitable land with extreme limitations. The land suitability evaluation methods used to produce this data are a modification of the Food and Agriculture Organisation (FAO) land evaluation approach. The land suitability analysis is described in full in the CSIRO NAWRA published report referenced in the "Citation" field of this metadata record. A companion dataset showing the reliability of this suitability data (showing areas of the catchment where there is greater or lesser confidence in the accuracy of the suitability data) is also supplied. The naming convention for these data is; ‘crop’ underscore ‘season’ underscore ‘irrigation type’ underscore ‘catchment code’ underscore ‘data type’ eg ‘SorgForage_dry_fur_F_Suit’ is Sorghum forage dry season furrow irrigated Fitzroy catchment suitability. The codes for season are; wet – wet season; dry – dry season; per – perennial; wet-dry – planted late wet season and grown through the dry season eg navy bean, soybean; wet-long – longer growing crops that grow through a wet season eg sugarcane. The codes for irrigation type are; spray – overhead spray irrigation; tric – trickle irrigation; mini-spray – mini spray irrigation; flood – flood irrigation; fur – furrow irrigation; rainfed – rainfed. The codes for data type are; suit – suitability data, CI – reliability data expressed as confusion index. It is important to emphasize that this is a regional-scale assessment: further data collection and detailed soil physical, chemical and nutrient analyses would be required to plan development at a scheme, enterprise or property scale. Several limitations that may have a bearing on land suitability were out of scope and not assessed as part of this activity (see section 1.1 and 2.1.2 of the cited report), these limitations include biophysical and socio-cultural. For example these land suitability raster datasets do not include consideration of the licensing of water, flood risk, contiguous land, risk of irrigation induced secondary salinity, or land tenure and other legislative controls. Some of these may be addressed elsewhere in NAWRA eg flooding was investigated within the Earth observation remote sensing activity and the risk of irrigation induced secondary salinity was assessed as part of the groundwater investigations.less

This versatile agricultural land data is a collection of raster datasets used to provide a synopsis of the individual land suitability data of the 126 crops and their specific irrigation management sy... morestems and seasons generated by the Northern Australia Water Resource Assessment (NAWRA). Five datasets are presented for each of the NAWRA catchments. The definitive versatile agricultural land dataset was determined by identifying where the largest number of 14 selected land management options were mapped as being suitable (i.e. suitability classes 1 to 3, refer to report cited with this metadata record). This analysis summarised the suitability of the selected land management options for each pixel, and highlights those pixels that are potentially more versatile for agricultural development because they are likely to suit a larger range of land use options and enterprises eg the score of zero represents the least versatile land, while the score of 14 represents the most versatile. The data values represent the number of land management options suitable for that pixel. The selected land management options for each catchment are different relative to general agronomic experience and development stakeholders of the catchment and were derived in consultation with the agricultural viability activity in NAWRA. These selections are presented in Table 3-1 of the published report; Land suitability of the Fitzroy, Darwin and Mitchell catchments. A technical report from the CSIRO Northern Australia Water Resource Assessment, part of the National Water Infrastructure Development Fund: Water Resource Assessments, CSIRO, Canberra, Australia Thomas et al 2018. Similarly. The selection of a different representative set of the 126 land use options for a particular study area would result in a different versatility map outcome for that catchment. In addition to the selected set of 14 land management options for each study area, versatile agricultural land is also presented using the subsets of each of the irrigation types (and rainfed cropping). In this case, the 126 land management options were assigned to rainfed (20), furrow (42), spray (44) or trickle irrigation (20). The data values represent the number of land management options suitable for that pixel. Analytical products like these help to identify land where particular types of irrigation-related infrastructure investment may be best targeted. This data provides improved land evaluation information to identify opportunities and promote detailed investigation for a range of sustainable development options. It is important to emphasize that this is a regional-scale assessment: further data collection and detailed analyses would be required to plan development at a scheme, enterprise or property scale. less
These aquaculture suitability raster datasets (in GeoTIFF format) indicate areas of potential suitability for freshwater and marine aquaculture species in earthen or lined ponds. A multi-criteria anal... moreysis, involved the integration of soil data and biophysical characteristics within a GIS spatial analysis environment to predict potential sites to inform decision making. A set of limitations and rules were adapted from (McLeod et al., 2002) to determine suitability. These aquaculture datasets were generated within the ‘Land suitability’ activity in consultation with the agricultural viability activity of the Northern Australia Water Resource Assessment (NAWRA). The aquaculture suitability analysis is described in full in the CSIRO NAWRA published report ‘Aquaculture viability. A technical report to the Australian Government from the CSIRO Northern Australia Water Resource Assessment, part of the National Water Infrastructure Development Fund: Water Resource Assessments. CSIRO, Australia.’ Irvin S, Coman G, Musson D and Doshi A (2018). There are five suitability classes coded 1-5. 1 – Highly suitable land with negligible limitations 2 – Suitable land with minor limitations 3 – Moderately suitable land with considerable limitations 4 – Currently unsuitable land with severe limitations 5 – Unsuitable land with extreme limitations. Each drop in suitability implies that more management input (and cost) is required to achieve incremental increases in production. The soil and land characteristics considered for all configurations include; clay content, sodicity and rockiness; and mainly refer to geotechnical considerations (e.g. construction and stability of pond walls). Other limitations, including slope, and the likely presence of gilgai microrelief and acid sulfate soils, infer more difficult, expensive and therefore less suitable development environments, and a greater degree of land preparation effort. Key considerations for earthen ponds included soil properties preventing pond leakage and soil acidity (pH); the latter taking into account negative growth responses of species from unfavourable pH values (i.e. biological limitation) as well as engineering, as pH may affect the structural integrity of earthen walls. Proximity to sea water was considered for marine species although the characteristics of tides and their suitability for marine aquaculture have not been applied in this analysis therefore the full inland distance of tidal waters has not been explored. The aquaculture suitability rules, including the limitation classes and suitability subclasses for each species by pond configuration, is provided in the above referenced publication. It is important to emphasize that this is a regional-scale assessment: further data collection and analyses would be required to plan development at a scheme, enterprise or property scale. less
