Hydrograph definition

Hydrograph means the graphical representation of flow volume over time of wastewater, infiltration, and inflow at a particular point in the Collection System. Hydrographs characterize diurnal variations in wastewater flow rates, as well as flow response to a wet weather event, at a particular point in the Collection System.

Hydrograph means a graph showing variation in depth or discharge of a stream of water over a period of time.

Hydrograph means a graph indicating stormwater runoff rate, inflow rate and discharge rate of stormwater, past a specific point over a time period;

Examples of Hydrograph in a sentence

• The within cell routing used a Unit Hydrograph (UH) approach to represent distribution of flow at the outlet point with respect to time from an impulse input at each source point and the channel routing used the linearized Saint-Venant equation to represent the flow at a downstream point as a function of the water velocity and the diffusivity, both of which may be estimated from geographical data (Lohmann et al.
