Plant community structure and observed inundation in vegetation plots collected as part of the Commonwealth Environmental Water Holder (CEWH) Flow-MER program in the Murray-Darling Basin. The CEWH’s Flow-MER program examines the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and is assisting the CEWH to demonstrate environmental outcomes and adaptively manage the water holdings. Monitoring and evaluation is focused in seven Selected Areas: the Junction of the Warrego and Darling rivers, Gwydir river system, Lachlan river system, Murrumbidgee river system, Edward/Kolety-Wakool river system, Goulburn River and Lower Murray River. This Flow-MER data set includes and extends the long-term data collected at the same sites during the Long Term Intervention Monitoring (LTIM) project (2014-2019). ###Acknowledgement The Commonwealth Environmental Water Holder and Flow-MER program acknowledge the First Nations peoples as the Traditional Owners and Custodians of the lands, waterways and skies of the Murray-Darling Basin.

This shapefile describes the outputs from the application of a decision support tool (Rohweder and others 2015) used to assist the Minnesota Valley Wetland Management District make thoughtful and strategic choices about where to spend its limited management resources. It incorporates landscape and management unit features to identify which Waterfowl Production Areas have the greatest biological potential with respect to priority resources and habitats. The district can use this information to prioritize and target management, which will help with development of annual habitat plans. This shapefile contains the relevant input criteria attributes used in the development of station objective models.

This policy contains a vision statement for the future of the Swan-Canning river system, policies based on the guiding principles for future land use and development in the precincts along the river system and performance criteria and objectives for specific precincts. The objectives of this policy are to: provide a regional framework for the preparation of precinct plans based on the precincts identified in the Swan River System Landscape Description; provide a context for consistent and integrated planning and decision making in relation to the river; and ensure that activities, land use and development maintain and enhance the health, amenity and landscape values of the river, including its recreational and scenic values.

This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. Riparian areas consist of the lands adjacent to streams, rivers, wetlands and lakes that are strongly influenced by the presence of water. They are often distinct from the surrounding landscape as the vegetation growth is very lush. These areas form a transition between dry land and open water and are characterized by the presence of hydrophilic vegetation and specific soil types. Riparian areas are usually very productive in terms of biomass and form critical wildlife habitat. Additionally, these areas often have standing water and are subjected to periodic flooding when high water levels fill the stream channel to the top of the bank. The term 'riparian' is derived from the Latin word for river bank. Riparian areas provide valuable food, shelter and travel corridors as well as an adjacent water source for wildlife and livestock. These zones are often densely vegetated and serve as stabilization against the erosive forces associated with lotic systems. Riparian areas provide filtration for surface runoff from the surrounding land and protect the water quality of flowing streams. They trap sediment and reduce the velocity of stream flow, thus reducing erosion in downstream areas. These areas provide detritus to their associated aquatic systems as well as a moderating effect on surface temperatures. The function of riparian areas in the landscape is regarded to be sufficiently critical that they are given special consideration in terms of the impact assessment resulting from human activities such as recreation, logging, oil and gas exploration, road construction and range management. Informatics Branch of Alberta Environment and Parks, Government of Alberta has been assigned the task of developing a provincial map of riparian areas. This project represents the initial effort to map riparian areas for the province. The riparian areas map is intended as input into ALCES (A Landscape Cumulative Effects Simulator), which is software developed by Forem Technologies. ALCES is being used to project the cumulative effects of various types of human activity on the landscape. This is accomplished by generating aspatial snapshots of regions within the provincial landscape and assuming that the current level of human impact continues. The methodology involved creating variable buffers by Natural Region based on Strahler Order coding for streams that had been merged with the associated perennial lakes. Higher Strahler Order codes were associated with wider buffers and drier Natural Regions were associated with narrower buffers. The result was a geodatabase of polygons that were intended to represent potential lotic riparian areas but the accuracy was poor. Landsat information and the Base Features Digital Elevation Model were incorporated to a minimal degree as refinements to the coverage but did not result in any improvement in the spatial accuracy of the data. This dataset is not recommended for use in riparian analysis. The Lotic Riparian - Digital Elevation Model Derived dataset, which was released in October 2011, is a better representation of the location and extent of riparian areas.

The Department of Water and Environmental Regulation produces floodplain mapping of rivers and major watercourses and provides floodplain development advice to ensure that proposed floodplain development has adequate flood protection and does not impact on the existing flood regime of the area. This advice is related to major river flooding only. Other issues, such as stormwater drainage and environmental and ecological considerations are not addressed. This dataset contains the location of levee banks (polylines) that mitigate the risk of flooding to the community and reduce potential property damage during major flood events. Note: To see the full scope of the floodplain mapping, 12 dataset layers are required to be loaded in the following order: FLOODPLAIN DATASET LAYERS: FPM Flood Level Points (m AHD) FPM Flood Level Contours (m AHD) FPM 1 in 100 (1%) AEP Floodway and Flood Fringe Line FPM Extent of Flooding FPM Levee Banks FPM Location of Cross Sections FPM 1 in 100 (1%) AEP Floodplain Development Control Area FPM Map Index FPM Bridges FPM Special Development Condition Area FPM 1 in 100 (1%) AEP Floodway and Flood Fringe Area FPM Floodplain Area The dataset covers the following areas: Avon River - Northam Townsite. Capel River - Capel Townsite. Cohn Creek - merredin Townsite. Corrigin Townsite. Exmouth Townsite. Five Mile Brook - Bunbury Townsite. Gascoyne River - Carnarvon Townsite. Greenough River – Indian Ocean to Walkaway. Serpentine River - North of Lake Amarillo. Vasse-Wonnerup Estuaries, Broadwater & New River - Busselton Townsite. Glossary: Annual exceedance probability (AEP) - the likelihood of occurrence of a flood of a given size or larger in any one year; usually expressed as a percentage. 1 in 100 AEP flood - this means that there is a 1 in 100 (or 1%) chance of a flow of this size or larger occurring in any one year. This flood has a 50% chance of being experienced at least once in a person's lifetime. The 1 in 100 AEP flood has been generally adopted in Australia and overseas as the basis for floodplain management planning. Floodplain - the portion of a river valley next to the river channel which is covered with water when the river overflows its banks during major river flows. The term also applies to land adjacent to estuaries which is subject to flooding. Australian Height Datum (AHD) - is a geodetic datum for altitude measurement in Australia. It was adopted in 1971 by the National Mapping Council as the datum to which all vertical control for mapping is to be referred. The datum is based on the mean sea level (1966-1968) being assigned the value 0.000m on the Australian Height Datum (AHD) at 30 tide gauges around the coast of the Australian continent. This dataset was formerly known as FPM Levee Banks (DOW-034)

As part of the stages of water restriction, the Department of Water and Environmental Regulation prepared a state map contained four different areas of water restrictions which are controlled by the Water Agency (Water Use) by-laws 2010. Dataset was formerly known as Sprinkler Restrictions - Water Agencies (Water Use) Bylaws (DOW-064)
