Total Runoff over Catchment Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Volume = Surface Runoff+Interflow+Baseflow+Channel Precipitation
Q_V = S_r+I+B+C
This formula uses 5 Variables

Variables Used

Runoff Volume - (Measured in Cubic Meter) - Runoff Volume is the average amount of water that flows down a particular river, per year, expressed as a volume of water flowing past a given point.
Surface Runoff - (Measured in Cubic Meter per Second) - Surface Runoff water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle.
Interflow - (Measured in Cubic Meter per Second) - Interflow is the lateral movement of water in the unsaturated zone.
Baseflow - (Measured in Cubic Meter per Second) - Baseflow is the portion of the streamflow that is sustained between precipitation events, fed to streams by delayed pathways.
Channel Precipitation - (Measured in Meter) - Channel Precipitation can be defined as the direct rainfall that falls onto surface of stream channel and other waterbodies, including throughfall from vegetation overhanging these water surfaces.

STEP 1: Convert Input(s) to Base Unit

Surface Runoff: 0.05 Cubic Meter per Second --> 0.05 Cubic Meter per Second No Conversion Required
Interflow: 2 Cubic Meter per Second --> 2 Cubic Meter per Second No Conversion Required
Baseflow: 16.96 Cubic Meter per Second --> 16.96 Cubic Meter per Second No Conversion Required
Channel Precipitation: 100 Millimeter --> 0.1 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_V = S_r+I+B+C --> 0.05+2+16.96+0.1

Evaluating ... ...

Q_V = 19.11

STEP 3: Convert Result to Output's Unit

19.11 Cubic Meter --> No Conversion Required

FINAL ANSWER

19.11 Cubic Meter <-- Runoff Volume

Total Runoff over Catchment

LaTeX Go Runoff Volume = Surface Runoff+Interflow+Baseflow+Channel Precipitation

Depth of rainfall given volume of rainfall

LaTeX Go Depth of Rainfall = Volume of Rainfall/Area of Accumulated Rain

Volume of rainfall

LaTeX Go Volume of Rainfall = Area of Accumulated Rain*Depth of Rainfall

Dredge or Burge Formula

LaTeX Go Peak Discharge = 19.6*Catchment Area/(Length of Basin)^(2/3)

Total Runoff over Catchment Formula

LaTeX Go

Runoff Volume = Surface Runoff+Interflow+Baseflow+Channel Precipitation
Q_V = S_r+I+B+C

What is Total Runoff & Amount of Rainfall?

The total runoff is equal to the total precipitation less the losses caused by evapotranspiration (loss to the atmosphere from soil surfaces and plant leaves), storage (as in temporary ponds), and other such abstractions.
The amount of rainfall is usually given as a depth over a specified area, assuming that all the rainfall accumulates over the surface and the unit for measuring the amount of rainfall.

What is Catchment Area?

A catchment area is the area from which rainfall flows into a river, lake, or reservoir. The catchment area is the first point of contact for rainfall. For the vast majority of tank-based rainwater harvesting systems, the catchment area is the roof surface. Each drop of precipitation that falls into a catchment area eventually ends up in the same river going to the sea if it doesn't evaporate.

How to Calculate Total Runoff over Catchment?

Total Runoff over Catchment calculator uses Runoff Volume = Surface Runoff+Interflow+Baseflow+Channel Precipitation to calculate the Runoff Volume, The Total Runoff over Catchment formula is defined as the sum of surface runoff, interflow, baseflow and channel precipitation through stream channels and waterbodies. Runoff Volume is denoted by Q_V symbol.

How to calculate Total Runoff over Catchment using this online calculator? To use this online calculator for Total Runoff over Catchment, enter Surface Runoff (S_r), Interflow (I), Baseflow (B) & Channel Precipitation (C) and hit the calculate button. Here is how the Total Runoff over Catchment calculation can be explained with given input values -> 9.17 = 0.05+2+16.96+0.1.

FAQ

What is Total Runoff over Catchment?

The Total Runoff over Catchment formula is defined as the sum of surface runoff, interflow, baseflow and channel precipitation through stream channels and waterbodies and is represented as Q_V = S_r+I+B+C or Runoff Volume = Surface Runoff+Interflow+Baseflow+Channel Precipitation. Surface Runoff water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle, Interflow is the lateral movement of water in the unsaturated zone, Baseflow is the portion of the streamflow that is sustained between precipitation events, fed to streams by delayed pathways & Channel Precipitation can be defined as the direct rainfall that falls onto surface of stream channel and other waterbodies, including throughfall from vegetation overhanging these water surfaces.
