Abstract
A great deal of information about the water balance of a catchment can be deduced by analysis of the hydrograph of runoff recorded at the outlet of the catchment. This paper describes procedures whereby inconsistencies between rainfall and runoff data, relationships between baseflow discharge and ground water storage, partial areas of surface runoff and surface storage capacities can be deduced by analysis of streamflow and rainfall records. The method is illustrated by analysis of data from the 7 sq km Back Creek catchment in southeastern Queensland.
