REPLENISH SOIL MOISTURE

Infiltration of the precipitated water helps in....

CLAYEY SOIL

Soil type with low infiltration rate but high water retention.

MODERATE

Loamy soil has with infiltration rate.

COHESION

Attraction between soil particles.

HIGH

High capillarity means infiltration,

HIGH INFILTRATION

Low compressibility and high porosity means infiltration.

URBANIZATION

Reduces land's natural ability to absorb water.

BIOLOGICAL AVTIVITY

Warm soil increases which lead to an increase in infiltration rate.

. VISCOSITY

In cold soil, is higher which reduces infiltration rates.

FROZEN GROUND

Why does tundra have poor infiltration?

RAINFALL INTENSITY

It overwhelms soil absorption and increases runoff.

SINGLE AND DOUBLE RING INFILTROMETER

Two commonly used infiltrometers.

3mm

Common thickness size of a ring used in infiltrometer.

. 2m

The height needed from where raindrops come from in a rainfall simulator setup

SINGLE RING INFILTROMETER

Determines the infiltration capacity curve using water depth over time.

WATER VOLUME

Measured in the inner ring of a double ring infiltrometer,

WATER BUDGET EQUATION

Equation that can be used to calculate infiltration losses.

INFILTRATION CAPACITY

Represents the upper limit of the infiltration rate.

INFILTRATION CAPACITY

Encompasses both surface infiltration and percolation.

INFILTRATION RATE

Speed at which water enters into the soil.

SANDY LOAM

Soil type which has a range of infiltration rate of 20-30 mm/hr.

10-20 mm/hr

Range of infiltration rate of a loam soil.

HYDROGRAPH ANALYSIS

7. Used to estimate the infiltration capacity of a small watershed by analyzing runoff hydrographs and rainfall
