Q1. Describe the entire
process of circulation and redistribution of water by the atmosphere and the
earth along with a neat sketch.
The process of circulation and redistribution of water by the atmosphere and the Earth is known as the hydrological cycle or water cycle. It involves several stages and processes, including evaporation, condensation, precipitation, runoff, infiltration, and transpiration. Here's a detailed explanation along with a simple sketch:
Evaporation:
The cycle begins with the evaporation of water from oceans, lakes, rivers, and
other water bodies due to the heat from the sun. Energy from the sun causes
water molecules at the surface to turn into water vapor and enter the
atmosphere.
Transpiration:
Transpiration is the process by which plants absorb water through their roots
and release it into the atmosphere through their leaves. This contributes to
the moisture content in the air.
Condensation:
As water vapor rises in the atmosphere, it cools down at higher altitudes. When
the air becomes saturated with moisture, it undergoes condensation, forming
clouds. This process is facilitated by condensation nuclei, such as dust
particles or aerosols, which provide surfaces for water vapor to condense onto.
Precipitation:
Condensed water droplets in clouds continue to grow until they become heavy
enough to fall back to the Earth's surface as precipitation. This can occur in
various forms, including rain, snow, sleet, or hail, depending on atmospheric
conditions.
Runoff:
Precipitation that falls onto the Earth's surface may flow over the land as
runoff, moving downhill due to gravity. Runoff collects in rivers, streams, and
eventually flows into larger bodies of water such as lakes and oceans.
Infiltration:
Some of the precipitation seeps into the ground through a process called
infiltration. This water percolates through the soil and fills underground
aquifers, which store groundwater.
Groundwater
Flow: Groundwater slowly moves underground, following the slope of the water
table, and may eventually discharge into surface water bodies or be drawn up by
plants through their roots.
Surface
Evaporation: Water from surface bodies such as lakes, rivers, and oceans may
also evaporate directly back into the atmosphere, completing the cycle.
This sketch
represents the various stages and processes involved in the hydrological cycle,
illustrating how water moves between the atmosphere, land, and water bodies.
Q2. Explain the
Rational method of peak runoff estimation. Write its assumptions.
Q3. Define infiltration.
Describe the procedure of its measurements. Enlist different factors affecting
infiltration.
Q4. Describe the
channel types and their characteristics with suitable examples. What is seepage
losses? Explain the factors affecting the seepage losses.
Q5. Discuss the
advantages of recording type rain gauge over non-recording type rain gauge.
Explain the Thiessen polygons method of mean rainfall measurement. Describe
their limitations also.
