Download .zipThe analysis for limitations for large scale development was completed by considering several different factors including slope, ground water, land use, soil drainage, shrink-swell potential, sewer and water service areas, and unique natural features. These factors are listed in order of increasing severity based on the degree of ease or cost in overcoming their associated limitations.

The soils used in this analysis were digitized from the paper final soil survey field sheets. These sheets were taped together to form an area covering each of the USGS 7.5 minute quadrangle maps in the county. The areas for each quadrangle were then digitized using run-length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 feet. The measurement increment along these lines was one decafoot (10 feet). The quadrangle files were then merged into a county file which has subsequently been converted to Arc/Info format.

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 analysis, 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. Lineage: These aquaculture suitability raster datasets have been generated from a range of inputs and processing steps. Following is an overview.

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 aquaculture suitability were out of scope and not assessed as part of this activity (refer to the 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, risk of irrigation or land tenure and other legislative controls. Some of these may be addressed elsewhere in ROWRA eg flooding was investigated by the Earth observation remote sensing group in the surface water activity. The Roper River Water Resource Assessment provides a comprehensive overview and integrated evaluation of the feasibility of aquaculture and agriculture development in the Roper catchment NT as well as the ecological, social and cultural (indigenous water values, rights and aspirations) impacts of development. Lineage: These aquaculture raster datasets has been generated from a range of inputs and processing steps. Following is an overview.

It applies pedometrics - the use of mathematical and statistical models that combine information from soil observations with information contained in correlated environmental variables, remote sensing images and some geophysical measurements. 7. Aquaculture suitability rules created for DSM attributes. 8. Suitability rules were run to produce limitation subclass datasets. 9. Final suitability data created for aquaculture options. 10. QA Quality assessment of these land suitability data was conducted by two methods. Method 1: Statistical (quantitative) assessment of the "reliability" of the spatial output data presented as a raster of the Confusion Index. Method 2: Collecting independent external validation site data combined with on-ground expert (qualitative) examination of outputs during validation field trips. A two-week validation field trip was conducted by on-ground and expert (qualitative) examination of outputs. These results are published in the report referenced above.

Land use data from 1982 aerial photography was utilized in the analysis to determine land not suitable for cultivation. Conservation management assumes a corn-corn-small grain-meadow-meadow rotation, or no till corn conr-notill soybeans and cover. Soil erosion rates were then compared to "T", the tolerable soil loss rate for the soil type.

Factors combined by the universal soil loss equation include: rainfall factor, ersosion factor "K", and slope length and steepness factor.
