Equal area catchment delineation

Hello,

Does anyone know how I might be able to generate a catchment grid/polygons such that each catchment is equal in area?

Typically, a flow accumulation threshold is set to initiate a stream grid and all other catchments are delineated based on stream junctions. This results in different sized catchments.

Might there be a method to generate a new catchment for equal drainage area intervals?
