Understanding urban wetland ecosystem services structure allows managers to base restoration efforts on multiple user end-benefits.Ary Creek can provide the coupled function of improving water quality and mitigating floods through delayed stormwater flow.It is fundamental to identify areas surrounded by water for the safety of individual should in case the water level raise beyond a reasonable doubt and might cause a flood.For many years,the Ary Creek catchment in Inverloch has been flooding and causing great problems for the inhabitants as well as the environment.The procedure is to develop models of the area around the catchment or watershed using Victorian Coastal LiDAR and other input data from the GIS(geographic information system).This study uses the real-time simulation in ArcSWAT—ArcGIS 10.3 and 3D in ArcScene 10.3,and the variables obtained from the soil and water assessment tool ArcSWAT such as the land use,soil and slope are the parameters measured to induce the flood.When certain portions of the Hydrologic response unit HRU,land use,soil or slope is changed due to temporal adjustment and climate change,then the model can predict zones of low,moderate and high flood risk.The 3D simulations appear to produce a visual model for decision-making,planning,management,and mitigation.The simulation helps in determining the extent of the flood by using animation.
