These lagoons are Wamberal Lagoon,Terrigal Lagoon, Avoca Lagoon and Cockrone Lake.The Study has been prepared in accordancewith the New South Wales Government’s Floodplain Development Manual (2005).The flood extents were filtered to remove shallow depths area generated by the direct rainfallmethodology. The criteria used to filter these shallow depths consisted of keeping areaswhere:• Depth > 0.10 m; OR• Depth > 0.05 m AND Velocity x Depth > 0.025 m2/s; OR• Velocity > 2 m/sFurther to these criteria, “puddles” of less than 100m2 were also removed from the extent.</DIV></DIV></DIV> Manly Hydraulics Laboratory and Central Coast Council Flooding 100yr 1%AEP Coastal Lagoons Parissa Ghanem Team Leader, Floodplain Management en FGDC Content Standards for Digital Geospatial Metadata FGDC-STD-001-1998 local time REQUIRED: The person responsible for the metadata information.
