Rainfall runoff relationship Solution

STEP 0: Pre-Calculation Summary

Formula Used

Surface Runoff = Precipitation-Runoff Losses
S_r = P-L
This formula uses 3 Variables

Variables Used

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.
Precipitation - (Measured in Meter) - Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations.
Runoff Losses - (Measured in Cubic Meter) - Runoff Losses is the water that is not available to runoff due to infiltration, evaporation, transpiration and surface storage.

STEP 1: Convert Input(s) to Base Unit

Precipitation: 0.3 Meter --> 0.3 Meter No Conversion Required
Runoff Losses: 0.25 Cubic Meter --> 0.25 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_r = P-L --> 0.3-0.25

Evaluating ... ...

S_r = 0.05

STEP 3: Convert Result to Output's Unit

0.05 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.05 Cubic Meter per Second <-- Surface Runoff

< 15 Water budget equation for a catchment Calculators

Daily Precipitation from Water Budget Continuity Equation

Go Precipitation = Daily Surface Outflow+Daily Seepage Outflow+Daily Lake Evaporation+Increase in Lake Storage in a Day+Daily Transpiration Loss-Daily Surface Inflow-Daily Groundwater Inflow

Mean annual flood proposed by natural environment research council

Go Mean Annual Flood = Constant C*Area^(0.94)*Stream Frequency^(0.27)*Slope of the Catchment^(0.16)*Soil Type Index^(1.23)*RSMD^(1.03)*(1+Area of Lakes or Reservoirs)^-0.85

Water Budget Equation for Catchment given Time Interval

Go Change in Mass Storage = Precipitation-Surface Runoff-Net Ground Water Flowing Outside Catchment-Evaporation from Water Body-Transpiration

Change in Storage of Water in Catchment

Go Change in Storage Volumes = Change in Groundwater Storage+Change in Soil Moisture Storage+Change in Groundwater Storage

Surface water storage given Storage of water in catchment

Go Change in Surface Water Storage = Storage of Water-Change in Soil Moisture Storage-Change in Groundwater Storage

Ground Water Storage given Storage of water in catchment

Go Change in Groundwater Storage = Storage of Water-Change in Surface Water Storage-Change in Soil Moisture Storage

Soil Moisture Storage given Storage of water

Go Change in Soil Moisture Storage = Storage of Water-Change in Surface Water Storage-Change in Groundwater Storage

Storage of Water in Catchment

Go Storage of Water = Change in Surface Water Storage+Change in Soil Moisture Storage+Change in Groundwater Storage

Mass outflow given Change in mass storage

Go Mass Outflow = Outflow Rate-Change in Mass Storage

Mass in flow given Change in mass storage

Go Outflow Rate = Change in Mass Storage+Mass Outflow

Continuity equation for water balance

Go Change in Mass Storage = Outflow Rate-Mass Outflow

Catchment Area given Peak Discharge in Jarvis formula

Go Catchment Area = (Peak Discharge/Coefficient)^2

Precipitation in Rainfall runoff relationship

Go Precipitation = Surface Runoff+Runoff Losses

Runoff losses in rainfall runoff relationship

Go Runoff Losses = Precipitation-Surface Runoff

Rainfall runoff relationship

Go Surface Runoff = Precipitation-Runoff Losses

Rainfall runoff relationship Formula

Surface Runoff = Precipitation-Runoff Losses
S_r = P-L

What is Rainfall-runoff relationship?

Rainfall-runoff relationship for any rainstorm depends on the dynamic interaction between rain intensity, soil infiltration and surface storage.

What is Runoff?

Runoff occurs whenever rain intensity exceeds the infiltration capacity of the soil, providing there are no physical obstructions to surface flow.

How to Calculate Rainfall runoff relationship?

Rainfall runoff relationship calculator uses Surface Runoff = Precipitation-Runoff Losses to calculate the Surface Runoff, Rainfall runoff relationship is defined by the parameters of Precipitation P, and Losses L i.e. water not available to runoff due to infiltration, evaporation, transpiration and surface storage. Surface Runoff is denoted by S_r symbol.

How to calculate Rainfall runoff relationship using this online calculator? To use this online calculator for Rainfall runoff relationship, enter Precipitation (P) & Runoff Losses (L) and hit the calculate button. Here is how the Rainfall runoff relationship calculation can be explained with given input values -> -4.7 = 0.3-0.25.

FAQ

What is Rainfall runoff relationship?

Rainfall runoff relationship is defined by the parameters of Precipitation P, and Losses L i.e. water not available to runoff due to infiltration, evaporation, transpiration and surface storage and is represented as S_r = P-L or Surface Runoff = Precipitation-Runoff Losses. Precipitation is the primary water input to the hydrologic cycle and is evaluated for all water budget calculations & Runoff Losses is the water that is not available to runoff due to infiltration, evaporation, transpiration and surface storage.

How to calculate Rainfall runoff relationship?

Rainfall runoff relationship is defined by the parameters of Precipitation P, and Losses L i.e. water not available to runoff due to infiltration, evaporation, transpiration and surface storage is calculated using Surface Runoff = Precipitation-Runoff Losses. To calculate Rainfall runoff relationship, you need Precipitation (P) & Runoff Losses (L). With our tool, you need to enter the respective value for Precipitation & Runoff Losses and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
