Average Inflow given Change in Storage Solution

STEP 0: Pre-Calculation Summary

Formula Used

Average Inflow = (Change in Storage Volumes+Average Outflow*Time Interval)/Time Interval
I_avg = (ΔSv+Q_avg*Δt)/Δt
This formula uses 4 Variables

Variables Used

Average Inflow - (Measured in Cubic Meter per Second) - Average Inflow during the time interval is the water entering a waterbody. It can also refer to the measure of the average volume of incoming water per unit of time.
Change in Storage Volumes - Change in Storage Volumes of water storage bodies on the stream is the difference of water incoming and outgoing.
Average Outflow - (Measured in Cubic Meter per Second) - Average Outflow during the time interval is the removal of water from the hydrological cycle. It can also refer to the measure of the average volume of outgoing water per unit of time.
Time Interval - (Measured in Second) - Time Interval is the amount of time required for the change from the initial to the final state.

STEP 1: Convert Input(s) to Base Unit

Change in Storage Volumes: 20 --> No Conversion Required
Average Outflow: 56 Cubic Meter per Second --> 56 Cubic Meter per Second No Conversion Required
Time Interval: 5 Second --> 5 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_avg = (ΔSv+Q_avg*Δt)/Δt --> (20+56*5)/5

Evaluating ... ...

I_avg = 60

What is Flood Routing?

Flood routing is a procedure to determine the time and magnitude of flow (i.e., the flow hydrograph) at a point on a watercourse from known or assumed hydrographs at one or more points upstream. The procedure is specifically known as flood routing if the flow is a flood.
