hydrographs show how a river responds differently to storms and heavy rainfall.
the graphs show the discharge of the river, the storm a certain amount of time.
Discharge is the amount of water ina river passing a given time. it measures in CUMECS (cubic meters per second)
Dischare depends on the river speed

What else can I help you with?
The unit of hydrograph for an infinitesimally small during of effective rainfall is called?
The unit of hydrograph for an infinitesimally small duration of effective rainfall is called unit hydrograph. It represents the response of a watershed to a unit input of effective rainfall over 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.
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
How do you calculate the lagtime of a hydrograph?
To calculate the lag time of a hydrograph, you first identify the peak discharge point on the hydrograph and then locate the corresponding point where the rainfall event begins. The lag time is the time difference between the start of the rainfall and the peak discharge, typically measured in hours. This value helps in understanding the response of a watershed to precipitation events.
What affects the shape of a storm hydrograph?
The shape of a storm hydrograph is influenced by factors such as precipitation intensity, duration, and distribution, as well as the characteristics of the watershed such as size, slope, soil type, land use, and vegetation cover. These factors determine how quickly water enters the river system and how quickly it moves through it, ultimately shaping the hydrograph.
When was Flashy created?
Flashy was created on 2008-10-21.
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 does the relief of the land effect a storm hydrograph?
The relief of the land significantly influences a storm hydrograph by affecting how quickly water flows into rivers and streams. Steep terrain can lead to rapid runoff, resulting in a sharp rise in discharge on the hydrograph, while flatter areas may allow for slower, more prolonged runoff. Additionally, the presence of features like valleys and hills can create variations in drainage patterns, further impacting the timing and shape of the hydrograph. Overall, the topography plays a crucial role in determining the response of a drainage basin to storm events.
On a hydrograph what does the area under the curve equal?
Total Volume of rainfall for that storm event
How do you work out lag time on a hydrograph?
the time between the heaviest rainfall and the peak discharge
