Outflow in First Reservoir Solution

STEP 0: Pre-Calculation Summary

Formula Used

Outflow in the Reservoir = (1/Constant K)*exp(-Time Interval/Constant K)
Q_n = (1/K)*exp(-Δt/K)
This formula uses 1 Functions, 3 Variables

Functions Used

exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Outflow in the Reservoir - (Measured in Cubic Meter per Second) - Outflow in the Reservoir is the amount of water discharged in the reservoir for the n reservoir where n can be 1,2 or 3.
Constant K - Constant K is for the catchment to be determined by flood hydrograph characteristics of the catchment.
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

Constant K: 4 --> No Conversion Required
Time Interval: 5 Second --> 5 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_n = (1/K)*exp(-Δt/K) --> (1/4)*exp(-5/4)

Evaluating ... ...

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.
