Attempt all the questions:
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
involves various intricate mechanisms that work together to maintain the water
cycle, also known as the hydrological cycle. Here's a description of the
process along with a sketch:
Evaporation:
The water cycle begins with the process of evaporation, where water from
oceans, lakes, rivers, and other water bodies is heated by the sun and
transformed into water vapor, rising into the atmosphere. This is depicted by
water bodies releasing water vapor into the air in the sketch.
Transpiration:
Plants also contribute to the water cycle through transpiration. Water absorbed
by plants from the soil is released into the atmosphere through small openings
in their leaves called stomata. This is shown by plants emitting water vapor
into the air in the sketch.
Condensation:
As water vapor rises into the atmosphere, it cools and condenses into tiny
droplets or ice crystals, forming clouds. This process is represented by water
vapor condensing into clouds in the sketch.
Precipitation:
When the condensed water droplets in clouds become too heavy to remain aloft,
they fall back to the Earth's surface as precipitation, which includes rain,
snow, sleet, or hail. This is illustrated by precipitation falling from clouds
onto the ground in the sketch.
Runoff:
Precipitation that does not infiltrate into the ground becomes surface runoff,
flowing into streams, rivers, and eventually back into oceans, lakes, or other
water bodies. This is depicted by water flowing along the ground into rivers
and oceans in the sketch.
Infiltration:
Some of the precipitation infiltrates into the ground, replenishing groundwater
reserves. This water may slowly seep into underground aquifers or flow
laterally to recharge surface water bodies. This process is represented by
water soaking into the ground in the sketch.
Sublimation: In
certain conditions, such as in high-altitude regions or during winter, ice and
snow may directly transform into water vapor without melting first. This
process is called sublimation and contributes to the water vapor content in the
atmosphere. It is not shown explicitly in the sketch but can be included as
arrows indicating the direct transition from ice/snow to water vapor.
Transportation:
Winds play a crucial role in transporting water vapor from one region to
another. Prevailing winds carry moisture-laden air masses, redistributing water
vapor across different geographical locations. This is shown by arrows
indicating wind movement in the sketch.
This
comprehensive process of evaporation, transpiration, condensation,
precipitation, runoff, infiltration, sublimation, and transportation
constitutes the water cycle, ensuring the continuous circulation and
redistribution of water on Earth. The sketch visually represents the
interconnectedness of these processes in maintaining the balance of water on
our planet.
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.
