Inflow Rate between Inter-Isochrone Area Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inflow Rate = 2.78*Inter-Isochrone Area/Time Interval
I = 2.78*A_r/Δt
This formula uses 3 Variables

Variables Used

Inflow Rate - (Measured in Cubic Meter per Second) - Inflow Rate for a given catchment area is the average volume of incoming water in unit time at any interval of time of the day.
Inter-Isochrone Area - (Measured in Square Meter) - Inter-Isochrone Area divides area of watershed into subareas with distinct runoff translation times.
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

Inter-Isochrone Area: 50 Square Meter --> 50 Square Meter No Conversion Required
Time Interval: 5 Second --> 5 Second No Conversion Required

STEP 2: Evaluate Formula

Inflow at Beginning of Time Interval for Routing of Time-Area Histogram

Go Inflow at the Beginning of Time Interval = (Outflow at the End of Time Interval-(Coefficient C2 in Muskingum Method of Routing*Outflow at the Beginning of Time Interval))/(2*Coefficient C1 in Muskingum Method of Routing)

Outflow at Beginning of Time Interval for Routing of Time-Area Histogram

Go Outflow at the Beginning of Time Interval = (Outflow at the End of Time Interval-(2*Coefficient C1 in Muskingum Method of Routing*Inflow at the Beginning of Time Interval))/Coefficient C2 in Muskingum Method of Routing

Outflow at End of Time Interval for Routing of Time-Area Histogram

Go Outflow at the End of Time Interval = 2*Coefficient C1 in Muskingum Method of Routing*Inflow at the Beginning of Time Interval+Coefficient C2 in Muskingum Method of Routing*Outflow at the Beginning of Time Interval

Time Interval at Inter-Isochrone Area given Inflow

Go Time Interval = 2.78*Inter-Isochrone Area/Inflow Rate

Inflow Rate between Inter-Isochrone Area

Go Inflow Rate = 2.78*Inter-Isochrone Area/Time Interval

Inter-Isochrone Area given Inflow

Go Inter-Isochrone Area = Inflow Rate*Time Interval/2.78

Inflow Rate between Inter-Isochrone Area Formula

Inflow Rate = 2.78*Inter-Isochrone Area/Time Interval
I = 2.78*A_r/Δt

What is Routing in Hydrology?

Routing is a technique used to predict the changes in the shape of a hydrograph as water moves through a river channel or a reservoir. In flood forecasting, hydrologists may want to know how a short burst of intense rain in an area upstream of a city will change as it reaches the city.

What are Isochrone Maps?

Isochrone and related maps are used to show the time taken for runoff water within a drainage basin to reach a lake, reservoir or outlet, assuming constant and uniform effective rainfall.

How to Calculate Inflow Rate between Inter-Isochrone Area?
