hydrograph

[′hī·drə‚graf]
(hydrology)
A graphical representation of stage, flow, velocity, or other characteristics of water at a given point as a function of time.

Hydrograph

 

a graph of the variations of water discharge over a period of time in a river during a year or part of a year (season, floodtime, high water). A hydrograph is constructed from data on the daily water discharge at an observation point. The amount of water discharge is plotted on the axis of ordinates and the time segments are plotted on the axis of abscissas.

The first step in the process was to carry out the variogram analysis which describes the spatial structure among samples for each variable in each state of the hydrograph. Based on the variogram parameters, in situ data was then spatially interpolated using the ordinary kriging method (Burrough and McDonnell, 1998).

A similar approach was used by Boughton (1985); however, our analysis uses a longer period of record, corrected catchment areas and hydrograph interpretation.
