Basin Slope given Basin Lag Solution

STEP 0: Pre-Calculation Summary

Formula Used

Basin Slope = ((Basin Length*Distance along Main Water Course)/((Basin Lag/Basin Constant)^(1/Basin Constant 'n')))^2
S_B = ((L_basin*L_ca)/((t_p/C_rL)^(1/n_B)))^2
This formula uses 6 Variables

Variables Used

Basin Slope - Basin Slope of the catchment under consideration.
Basin Length - (Measured in Kilometer) - Basin Length measured along the watercourse from the basin divide to the gauging station in km.
Distance along Main Water Course - (Measured in Kilometer) - Distance along Main Water Course from the gauging station to a point opposite to the watershed centroid in km.
Basin Lag - (Measured in Hour) - Basin Lag is the elapsed time between the occurrences of the centroids of the effective rainfall.
Basin Constant - Basin Constant to determine the base lag with respect to basin slope.
Basin Constant 'n' - Basin Constant 'n' to determine the base lag with respect to basin slope.

STEP 1: Convert Input(s) to Base Unit

Basin Length: 9.4 Kilometer --> 9.4 Kilometer No Conversion Required
Distance along Main Water Course: 12 Kilometer --> 12 Kilometer No Conversion Required
Basin Lag: 6 Hour --> 6 Hour No Conversion Required
Basin Constant: 1.03 --> No Conversion Required
Basin Constant 'n': 0.38 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_B = ((L_basin*L_ca)/((t_p/C_rL)^(1/n_B)))^2 --> ((9.4*12)/((6/1.03)^(1/0.38)))^2

Evaluating ... ...

S_B = 1.19302527093235

STEP 3: Convert Result to Output's Unit

1.19302527093235 --> No Conversion Required

FINAL ANSWER

1.19302527093235 ≈ 1.193025 <-- Basin Slope

What is Baseflow?

Baseflow is a portion of streamflow that is not directly generated from the excess rainfall during a storm event. In other words, this is the flow that would exist in the stream without the contribution of direct runoff from the rainfall.

How to Calculate Basin Slope given Basin Lag?

Basin Slope given Basin Lag calculator uses Basin Slope = ((Basin Length*Distance along Main Water Course)/((Basin Lag/Basin Constant)^(1/Basin Constant 'n')))^2 to calculate the Basin Slope, The Basin Slope given Basin Lag formula is defined as the slope determined by summing lengths of all contours in the basin multiplied by the contour interval and dividing the product by drainage area. Basin Slope is denoted by S_B symbol.
