{ "currentVersion": 10.91, "id": 21, "name": "Upper_Namoi_Large_Design_Floods", "type": "Feature Layer", "description": "Display using 'Large_design'The Upper Namoi has been divided into several sub-areas. These sub-areas conform to the existing rural floodplain management studies and plans where hydraulic modelling was previously performed. For areas that are not covered by an existing plan, sub-areas have been delineated to represent geographical recognisable areas (e.g. Boggabri to Narrabri-1984 event, and Breeza to Ruvigne-1 in 10 Year design Event). This shapefile spatially identifies the different large design floods for each area.While a consistent design flood across the valley would be neater, there are several reasons for utilising the existing design floods:\u2022Allow for continuity between the existing and valley wide plan\u2022The variability of the ARI across the valley, means no one historical event can be used\u2022Hydrology modelling and calculations would need to be re-done, some files and calculations may be missing.MIKE 11 was used for all modelsModel datasets from existing rural floodplain management studies, within the Upper Namoi boundary, were used. These datasets (cross-sections, flowlines, floodmarks, etc) can be found within the NAMOI data package for the following areas:Upper CoxsLower CoxsCarroll to BoggabriUpper YarramanWarrah CreekBorambil GunnadillyBlackvilleCaroon to Breeza", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 4283, "latestWkid": 4283 }, "copyrightText": "", "parentLayer": { "id": 17, "name": "Upper Namoi Valley FMP 2019" }, "subLayers": [], "minScale": 0, "maxScale": 0, "drawingInfo": { "renderer": { "type": "uniqueValue", "field1": "Large_design", "field2": null, "field3": null, "defaultSymbol": null, "defaultLabel": null, "uniqueValueInfos": [ { "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 179, 252, 187, 255 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 110, 110, 110, 255 ], "width": 0.4 } }, "value": "1971", "label": "1971", "description": "" }, { "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 228, 204, 252, 255 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 110, 110, 110, 255 ], "width": 0.4 } }, "value": "1984", "label": "1984", "description": "" }, { "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 189, 245, 252, 255 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 110, 110, 110, 255 ], "width": 0.4 } }, "value": "1998", "label": "1998", "description": "" }, { "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 252, 216, 184, 255 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 110, 110, 110, 255 ], "width": 0.4 } }, "value": "Probabilistic 5% AEP", "label": "Probabilistic 5% AEP", "description": "" } ], "fieldDelimiter": "," }, "transparency": 0, "labelingInfo": null }, "defaultVisibility": false, "extent": { "xmin": 750474.8421963186, "ymin": 6474432.176345525, "xmax": 880005.0081645485, "ymax": 6642112.80329372, "spatialReference": { "wkid": 28355, "latestWkid": 28355 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "displayField": "Large_design", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null }, { "name": "Large_design", "type": "esriFieldTypeString", "alias": "Large_design", "length": 50, "domain": null }, { "name": "Area_ha", "type": "esriFieldTypeDouble", "alias": "Area_ha", "domain": null }, { "name": "Shape", "type": "esriFieldTypeGeometry", "alias": "Shape", "domain": null }, { "name": "Shape.STArea()", "type": "esriFieldTypeDouble", "alias": "Shape.STArea()", "domain": null }, { "name": "Shape.STLength()", "type": "esriFieldTypeDouble", "alias": "Shape.STLength()", "domain": null } ], "geometryField": { "name": "Shape", "type": "esriFieldTypeGeometry", "alias": "Shape" }, "indexes": [ { "name": "R799_pk", "fields": "OBJECTID", "isAscending": true, "isUnique": true, "description": "" }, { "name": "S739_idx", "fields": "Shape", "isAscending": true, "isUnique": true, "description": "" } ], "subtypes": [], "relationships": [], "canModifyLayer": false, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Map,Query,Data", "maxRecordCount": 1000, "supportsStatistics": true, "supportsAdvancedQueries": true, "hasZ": true, "hasM": true, "supportedQueryFormats": "JSON, geoJSON", "isDataVersioned": false, "effectiveMinScale": 3.6978595474472E7, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": true, "supportsHavingClause": true, "supportsCountDistinct": true, "supportsOrderBy": true, "supportsDistinct": true, "supportsPagination": true, "supportsTrueCurve": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": true }, "supportsDatumTransformation": true, "hasGeometryProperties": true, "geometryProperties": { "shapeAreaFieldName": "Shape.STArea()", "shapeLengthFieldName": "Shape.STLength()", "units": "esriDecimalDegrees" }, "dateFieldsTimeReference": null, "supportsCoordinatesQuantization": true }
