Service Description: Layer used in public web app to provide Flood Estimation for New Zealand

 1. Modelled flood frequency estimates on river lines.

 2. At-site flood statistics at flow recorders used in the model development

3. Return period estimates of the area-rain intensity values for small catchments. Where results display '-1' the catchment is greater than 30 square kilometres and no answer is available. Numbers need to be multiplied by the Rational Method 'C' factor to give the required flood magnitude.

4. Annual data values at flow recorders used in the model development. Layer coming later.
