Time Interval at Inter-Isochrone Area given Inflow Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Time Interval - (Measured in Second) - Time Interval is the amount of time required for the change from the initial to the final state.
Inter-Isochrone Area - (Measured in Square Meter) - Inter-Isochrone Area divides area of watershed into subareas with distinct runoff translation times.
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.

STEP 1: Convert Input(s) to Base Unit

Inter-Isochrone Area: 50 Square Meter --> 50 Square Meter No Conversion Required
Inflow Rate: 28 Cubic Meter per Second --> 28 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Δt = 2.78*A_r/I --> 2.78*50/28

Evaluating ... ...

Δt = 4.96428571428571

STEP 3: Convert Result to Output's Unit

4.96428571428571 Second --> No Conversion Required

FINAL ANSWER

4.96428571428571 ≈ 4.964286 Second <-- Time Interval

What is Routing in Hydrology?

Routing is a technique used to predict the changes in 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.
