Instantaneous Unit Hydrograph
hyetograph is the graph between intensity of rainfall and time whereas hydrograph is the graph between discharge and time.
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.
amount of precipitation
how do you compare and contrast hydrographs
the amount of discharge in a river over a period of time
because there is
IS the technique of determining flood hydrograph at a section of river
The peak rainfall is the highest amount of rain in a place on a hydrograph.
lag time=(time it takes the s-wave to travel)-(time it takes the p-wave to travel)
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.
