UDAY AVASAK, IFS MAHARASHTRA- 6-18 AUG 2012
MODEL LESSON PLAN
Title:
SOIL AND WATER CONSERVATION: (HYDROLOGY and WATERSHED MANAGEMENT)
1: Name of the Course: Induction course for Forest Guards.
2: Participants’ profile:
All the Trainees are fresh recruits in Forest Department in the age group of 25 to 35. Most of them are graduates. About
10% are Post-graduates. All are XII Science pass. Out of these about 25% have done Botany / Zoology. About 5% have worked in the
Government Department in different capacity before entry in Forest Department.
Total number of Trainees will be 35 to 40 per Batch.
3. Objectives:
At the end of the session the participants will be able to:
a. Explain the process of Hydrological Cycle, (Water Cycle).
b. Define Runoff of a drainage system and list out various factors affecting it.
c. Define and Describe Watershed.
d. Explain the watershed management and its relevance to soil and water conservation.
4. Backward linkage required.
Geology, study of various rocks formation process, Natural elements that constitute Earth’s crust. Plants Succession, stages of Vegetation and
ecosystem development. Knowledge of Contouring and leveling (Engineering)

5. Forward linkages to be taken care of:
SOIL EROSION, CAUSES, TYPE OF- WATER & WIND, SOIL & WATER CONSERVATION MEASURES, VARIOUS TYPES OF- VEGETATIVE BARRIERS/
CHECKS AND VARIOUS ENGENEERING STRUCTURES, Gabian, check DAMS Etc. In relation to forest land, FIELD VISITS : TO SEE SUCH METHODS.

WARMING UP
“Water means Life” Life can’t exist without
water. Water is ‘precious’. Human civilization
cradle around water only Soil and water..
Available water limited!

HYDROLOGY:
HYDROLOGICAL
CYCLE
The water cycle, also known as the hydrologic
cycle or H2O cycle, describes the continuous
movement of water on, above and below the
surface of the Earth
the physical processes
of evaporation, condensation,
precipitation, infiltration, runo
ff, and subsurface flow. In so
doing, the water goes through
different phases: liquid, solid,
and gas
The water cycle figures significantly in the
maintenance of life and ecosystems on Earth

WATERSHED :
CONCEPT
Definition: A watershed is an area that supplies
water by surface or subsurface flow to a given
drainage system or body of water, be it a
stream, river, wetland, lake, or ocean (World
Bank 2001)
Classification as per sizes,

Watershed
Management
Watershed management typically refers to
management at the level of the micro- or subwatershed. Catchment is generally used
synonymously with watershed.

WATERSHED
MANAGEMENT &
ITS REVENCE TO
SOIL & WATER
CONSERVATION
The integrated concepts of watershed
management provide a framework for
sustainable development, while watershed
management practices provide the tools for
making the framework operational.
