The catchment length (or hydraulic length) is the length measured along a principal watercourse. The length to catchment centroid is the length measured along the principal watercourse, from the catchment outlet to a point located closest to the catchment centroid.

What is the catchment area ratio?

Comment: A ratio of approximately 3:1 is common and widely appropriate. i.e. The catchment area must be approximately twice as large as the cultivated area. Comment: Ratios are always lower for microcatchment systems due to a higher efficiency of water use and a higher runoff coefficient.

How does local catchment work?

1. Rainwater is collected through a comprehensive network of drains, canals and rivers and channelled to the reservoirs before it is treated for drinking water. 2. Used water is collected in a network of underground sewers that lead to a water reclamation plant.
