==Terminology== The discharge is measured at a specific point in a river and is typically time variant. Types of hydrograph can include: ==Baseflow separation== A stream hydrograph is commonly conceptualized to include a baseflow component and a direct runoff component. The former represents the relatively steady contribution to stream discharge f...
A graph illustrating changes in the rate of flow from a catchment with time
A graph that shows the change of a water-related variable over time. Example
A graph describing stream discharge over time.
hydrograph 1. An instrument for transmitting sound under water and recording messages so received. 2. A graph showing the variation of level, speed of flow, or another quantity at some point on a river. Cross references of word families that refer to 'water': aqua-; hydat-; hygro-.
Graph showing how the discharge of a river varies with time (generally over a matter of days). By studying hydrographs, water engineers can predict when flooding is likely and take action to prevent it. A hydrograph shows the lag time, or delay, between peak rainfall and the resultant peak in dischar...
Graph of variation of stream flow over time.
a graph of the water level or rate of flow of a body of water as a function of time, showing the seasonal change.
