Snyder's Equation for Standard Duration of Effective Rainfall Formula

LaTeX Go

Standard Duration of Effective Rainfall = Basin Lag/5.5
t_r = t_p/5.5

Which factors influence the amount of effective rainfall?

The fraction of effective rainfall increases with increased water-holding capacity in the soil. The amount of water held and retained by a soil depends upon its depth, texture, structure, and organic matter content, the finer the texture, the greater the storage capacity.

What is Peak Flood Discharge?

In hydrology, the term peak discharge stands for the highest concentration of runoff from the basin area. The concentrated flow of the basin greatly exaggerated and overtops the natural or artificial bank, and this might be called flood.

How to Calculate Snyder's Equation for Standard Duration of Effective Rainfall?

Snyder's Equation for Standard Duration of Effective Rainfall calculator uses Standard Duration of Effective Rainfall = Basin Lag/5.5 to calculate the Standard Duration of Effective Rainfall, The Snyder's Equation for Standard Duration of Effective Rainfall formula is the duration for when precipitation is equal to the difference between total rainfall and actual evapotranspiration. At ground level, water from effective rainfall is split into two fractions: surface run-off and infiltration. Standard Duration of Effective Rainfall is denoted by t_r symbol.

How to calculate Snyder's Equation for Standard Duration of Effective Rainfall using this online calculator? To use this online calculator for Snyder's Equation for Standard Duration of Effective Rainfall, enter Basin Lag (t_p) and hit the calculate button. Here is how the Snyder's Equation for Standard Duration of Effective Rainfall calculation can be explained with given input values -> 0.000303 = 21600/5.5.

FAQ

What is Snyder's Equation for Standard Duration of Effective Rainfall?

The Snyder's Equation for Standard Duration of Effective Rainfall formula is the duration for when precipitation is equal to the difference between total rainfall and actual evapotranspiration. At ground level, water from effective rainfall is split into two fractions: surface run-off and infiltration and is represented as t_r = t_p/5.5 or Standard Duration of Effective Rainfall = Basin Lag/5.5. Basin Lag is the elapsed time between the occurrences of the centroids of the effective rainfall.

How to calculate Snyder's Equation for Standard Duration of Effective Rainfall?

The Snyder's Equation for Standard Duration of Effective Rainfall formula is the duration for when precipitation is equal to the difference between total rainfall and actual evapotranspiration. At ground level, water from effective rainfall is split into two fractions: surface run-off and infiltration is calculated using Standard Duration of Effective Rainfall = Basin Lag/5.5. To calculate Snyder's Equation for Standard Duration of Effective Rainfall, you need Basin Lag (t_p). With our tool, you need to enter the respective value for Basin Lag and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Standard Duration of Effective Rainfall?

In this formula, Standard Duration of Effective Rainfall uses Basin Lag. We can use 2 other way(s) to calculate the same, which is/are as follows -

Standard Duration of Effective Rainfall = Non-standard rainfall duration-4*(Modified Basin Lag-Basin Lag)
Standard Duration of Effective Rainfall = -(4*(Modified Basin Lag-Basin Lag)-Non-standard rainfall duration)
