How do you work out lag time on a hydrograph?
the time between the heaviest rainfall and the peak discharge
Why is there a lag time between the peak rainfall and peak discharge on a hydrograph?
because there is
What does the lag time showon a hydrograph?
It shows us the time between the peak rainfall and peak discharge. Peak rainfall is the highest rain amount. Peak discharge is the highest the water level reaches in the river.
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 is does a hydrograph show?
the amount of discharge in a river over a period of time
The unit of hydrograph for an infinitesimally small during of effective rainfall is called?
Instantaneous Unit 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.
What is the difference between an inside lag and an outside lag?
Inside lag is the time to implement (pass) a policy, while outside lag is the time it needs to take effect.
How is lag time affected by distance?
The impact of an event happening at a distance takes some time to reach the observer. This is the lag time and, as the distance increases, the lag time increases. The increase depends on the velocity of transmission of the information. For example, the lag time for a flash of lightning depends on the speed of light; the lag time for the clap of thunder depends on the speed of sound; the lag time for the person that the lightning bolt missed depends on how fast they can run to you.
What is the time lag between the arrival of light at a metal surface and the emission of photoelectron?
no time lag.................
What is lag in statistic?
An event occuring at time t+k is said to lag behind event occurring at time t. Extent of lag is k.
