Length of Overland Flow given Inlet Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Overland Flow = (((Inlet Time)^(1/0.385)*Fall of level)/0.885)^(1/3)
L_ob = (((T_i)^(1/0.385)*H)/0.885)^(1/3)
This formula uses 3 Variables

Variables Used

Length of Overland Flow - (Measured in Meter) - Length of Overland Flow is a length of water over the ground before it gets concentrated into certain stream channels.
Inlet Time - (Measured in Second) - Inlet Time is the time taken by water to flow overland.
Fall of level - (Measured in Meter) - Fall of level from the critical point to the point of mouth of drain.

STEP 1: Convert Input(s) to Base Unit

Inlet Time: 94.78 Minute --> 5686.8 Second (Check conversion here)
Fall of level: 10.05 Meter --> 10.05 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_ob = (((T_i)^(1/0.385)*H)/0.885)^(1/3) --> (((5686.8)^(1/0.385)*10.05)/0.885)^(1/3)

Evaluating ... ...

L_ob = 4005.98073616455

STEP 3: Convert Result to Output's Unit

4005.98073616455 Meter -->4.00598073616456 Kilometer (Check conversion here)

FINAL ANSWER

4.00598073616456 ≈ 4.005981 Kilometer <-- Length of Overland Flow

Length of Overland Flow given Inlet Time

Go Length of Overland Flow = (((Inlet Time)^(1/0.385)*Fall of level)/0.885)^(1/3)

Total Fall of Level from Critical Point to Mouth of Drain given Inlet Time

Go Fall of level = (Length of Overland Flow)^3/((Inlet Time)^(1/0.385)/0.885)

Inlet Time or Time of Equilibrium

Go Inlet Time = (0.885*((Length of Overland Flow)^3/Fall of level))^0.385

Channel Flow Time given Total Time of Concentration

Go Channel Flow Time = Time of Concentration-Inlet Time

Inlet Time given Total Time of Concentration

Go Inlet Time = Time of Concentration-Channel Flow Time

Total Time of Concentration

Go Time of Concentration = Inlet Time+Channel Flow Time

Length of Overland Flow given Inlet Time Formula

Length of Overland Flow = (((Inlet Time)^(1/0.385)*Fall of level)/0.885)^(1/3)
L_ob = (((T_i)^(1/0.385)*H)/0.885)^(1/3)

What is Overland Flow ?

The overland flow describes the tendency of water to flow horizontally across land surfaces when rainfall has exceeded infiltration capacity and depression storage capacity.
