  • Flood Plains

    Auckland Council
    The flood plains indicate the area of land inundated by runoff in a storm event that has a 1 percent or greater probability of occurring in any given year, assuming maximum probable development (MPD) and future climate change. The flood plains are mapped from hydraulic modelling results. Information specific to each flood plain is accessible using the...

  • Flood Prone Areas

    Auckland Council
    Flood prone areas (FPA) are potential ponding areas that have no natural outlet and may flood frequently.FPA are topographical depressions. The areas occur naturally or are created by dammed gullies created by man-made features such as roads and railway embankments. The flood prone extent is the area water will pond up to in a 1% AEP extreme rainfall...

    Auckland Council
    The high water levels are provided for a range of Average Recurrence Interval (ARI) events. Average recurrence interval is often referred to as a return period. These can be approximately converted to Annual Exceedance Probability (AEP), the probability of occurrence each year, by the following conversion table:ARI (yr)AEP (%)25052010102055021001The high...

  • Southland Groundwater Management Zones (RWP 2010)

    Environment Southland
    Groundwater zones effectively encompass separate groundwater systems and are utilised as a framework for monitoring, investigation and management of groundwater resources in the Southland region. These groundwater zones are classified into four basic aquifer types which aggregate spatially separate aquifer systems on the basis of similarities in...

  • Southland Tertiary Aquifer Zones

    Environment Southland
    Tertiary aquifers are those that occur in older Tertiary age sedimentary deposits (between 66 and 2.6 million years old). Geological reports, maps, and borelogs have been used to identify discreet aquifer units within the Tertiary age geological formations that exist in Southland. These formations consist of a combination of terrestrial, intertidal and...

  • Coastal Confined Gravel Aquifer System

    Environment Canterbury
    The Coastal Confined Gravel Aquifer System is a relatively narrow band of confined gravel aquifers, situated near the coast between the Ashley and Rakaia rivers, bounded by the coastal marine area, Banks Peninsula, and on the western side by the line where sediments in the overlying confining layer are three metres thick. The aquifer system consists of at...

  • Residual Flows

    Environment Canterbury
    Many resource consents contain a condition limiting the taking of water when a river or waterway is on restriction.A residual flow applies to specific consents that take water from a tributary of a main river. A residual flow recognises that a tributary stream often has different flow characteristics from the main river stem. It is set at the point of...
