Hydrographs are important for forecasting floods, as they are able to tell authorities the time they have until flooding occurs, the severity of the flood and the area that could possible be affected. It enables us to act towards either prevention (setting up levy's) or to escape the scene without harm.

The unit of hydrograph for an infinitesimally small during of effective rainfall is called?
Instantaneous Unit Hydrograph
What is the difference between hydrograph and hyetograph?
hyetograph is the graph between intensity of rainfall and time whereas hydrograph is the graph between discharge and time.
What is a flood hydrograph?
A hydrograph is showing the discharge (rate of flow) versus the time past in a specific river point. One of the types of hydrography is called a flood hydrograph, it is used to measure the river's characteristic basically a dual plot of discharge and rainfalls.
What affects the shape of a storm hydrograph?
amount of precipitation
How do you contrast a storm hydrograph?
how do you compare and contrast hydrographs
What is does a hydrograph show?
the amount of discharge in a river over a period of time
Why is there a lag time between the peak rainfall and peak discharge on a hydrograph?
because there is
What is the flood routing types?
IS the technique of determining flood hydrograph at a section of river
What is Rainfall Peak?
The peak rainfall is the highest amount of rain in a place on a hydrograph.
How would the hydrograph of a large rainstorm change after urbanization of an area?
Urbanization can lead to increased impervious surfaces like roads and buildings, reducing infiltration and increasing runoff. This can cause a faster rise in streamflow during a rainstorm, resulting in a higher peak discharge and a shorter lag time in the hydrograph. Additionally, urbanization can increase the volume of runoff, leading to larger flood peaks and potentially worsening flood events.
How do you work out lag time on a hydrograph?
the time between the heaviest rainfall and the peak discharge
What is peak rainfall mean?
The peak rainfall is the highest amount of rain in a place on a hydrograph.
