What else can I help you with?
On a hydrograph what does the area under the curve equal?
Total Volume of rainfall for that storm event
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.
Why is a storm hydrograph useful?
A storm hydrograph is useful because it shows how a watershed responds to a storm event by plotting discharge over time. This helps in predicting peak flows, assessing flood risk, and designing infrastructure to manage stormwater effectively. It also provides valuable information for watershed management and water resource planning.
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.
What is an attenuated peak in a storm hydrograph?
Firstly an attenuation is the reduction in the peak of a hydro-graph as it movesdownstream, resulting in a more broad, flat hydro-graph.Therefore the attenuated peak is the highest point before it attenuates.
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 is a sentence with the word contrast?
The tall Kenyan man presented a sharp contrast to the small Korean woman standing next to him.
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 do you work out lag time on a hydrograph?
the time between the heaviest rainfall and the peak discharge
