| We have been very pleased to see the idea adopted in other river catchments. |
| This challenges the concept of 800-metre walkable catchments for train stations. |
| The catchments of these basins may have a very large surface area, collecting run-off from a vast region. |
| If the latter was the case, there could be a higher risk of winter flooding in a number of the region's river catchments. |
| The Tararua Forest Park protects mountain landscapes, considerable tracts of indigenous forests and the upper catchments of many rivers. |
| Engineers looking at flood defences, modelling catchments, sewer systems and watercourses take many factors into consideration. |
