    Hello All,

    I've been asked "how many rain gauges" are required to provide enough data for accurate calibration of a collection system (sewer/foul) model. With the accessibility of Met Offic radar...

    I've been thinking about Operational Water Modelling Systems (or "Live" systems) and it seems to me that there are many different ways these systems can be used.

    Examples I can think...
  13. Does anyone have any quantifiable measures for determining how accurate a model is ?

    Hello All,

    I've been asked about what type of assessments people undertake to show that a sewer model is suitably calibrated.

    Here in Victoria, Australia, we review individual sites (flow,...
