Storage of Water in Catchment Solution

STEP 0: Pre-Calculation Summary

Formula Used

Storage of Water = Change in Surface Water Storage+Change in Soil Moisture Storage+Change in Groundwater Storage
S = ΔSs+ΔSm+ΔS
This formula uses 4 Variables

Variables Used

Storage of Water - (Measured in Cubic Meter) - Storage of Water in a catchment.
Change in Surface Water Storage - (Measured in Cubic Meter) - Change in Surface Water Storage in a catchment.
Change in Soil Moisture Storage - (Measured in Cubic Meter) - Change in Soil Moisture Storage in a catchment.
Change in Groundwater Storage - (Measured in Cubic Meter) - Change in Groundwater Storage by an amount ΔS equal to the difference between discharge and recharge.

STEP 1: Convert Input(s) to Base Unit

Change in Surface Water Storage: 5 Cubic Meter --> 5 Cubic Meter No Conversion Required
Change in Soil Moisture Storage: 6 Cubic Meter --> 6 Cubic Meter No Conversion Required
Change in Groundwater Storage: 7 Cubic Meter --> 7 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = ΔSs+ΔSm+ΔS --> 5+6+7

Evaluating ... ...

S = 18

STEP 3: Convert Result to Output's Unit

18 Cubic Meter --> No Conversion Required

FINAL ANSWER

18 Cubic Meter <-- Storage of Water

< 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

Storage of Water in Catchment Formula

Storage of Water = Change in Surface Water Storage+Change in Soil Moisture Storage+Change in Groundwater Storage
S = ΔSs+ΔSm+ΔS

What is Catchment Area?

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.
