16. What is WATERSHED MANAGEMENT:
 A watershed, also called a
"drainage basin”, is an area in
which all water flowing into it goes
to a common outlet, such as the
same river or reservoir.

20. Features of watershed
management:
 Size and shape of watershed
 Watershed boundary
 Topography of watershed land
 Soil type
 Amount and intensity of rainfall
 Vegetative cover
 Water resource and their capabilities.
Total Watershed Management 20

21. Objectives of watershed
management
 Conservation of soil and water.
 To manage and utilize the runoff water for
useful purpose.
 To protect, conserve and improve the land
of watershed for more efficient and
sustained production
 To increase infiltration of rainwater.
Total Watershed Management 21

22.  To protect and enhance the water resource
originating in the watershed.
 To check soil erosion and to reduce the effect of
sediment yield on the watershed.
 To improve and increase the production of
timbers, fodder and wild life resource.
 To enhance the ground water recharge,
wherever applicable
Total Watershed Management 22

23. Control measures:-
 Engineering measures ( Structural
practices)
1. Contour bunding
2. Terracing
3. Construction of earthen
embankment
4. Construction of check dams
5. Construction of farm ponds
6. Construction of diversion
7. Gully controlling structure

24. CASE STUDY:
 Village Wankute is located high in
Sahyadri mountain range of
Maharashtra.
 It was dry and nearly barren place in
1990 and water was supplied with the
help of tankers.
 Problem was, the rainfall was limited.
 With the help of one NGO, they
implemented various techniques of
WSM like construction of bunds,
checkdams,vegetation,plantation.
Total Watershed Management 24

25.  Now, water table has increased, no need
of tankers.
 Overall employment increased.
 All types of crops can be cultivated.
 No shortage of potable water and no
waterborne diseases.
 Built new community hall,2 schools,
public health center etc.
 WSM have contributed to overall
development of village very well.

27. NEED OF WATERSHED
MANAGEMENT IN MADGYAL
 The precipitation intensity and
characteristic vary drastically in Sangli
district.
 In the parts of Krishna river basin and
vicinity the rainfall statistics are
comparatively good and enough to
recharge major catchment.
 On the contrary, the eastern region is
more drought prone and is
consistently under water scarce
condition.

28. MADGYAL
 Madgyal is a village in Jath Taluka,
district Sangli.
 Coordinates are Latitude 17°02’56.94” N
Longitude 75° 13’8.14” E
 It is 21.8 km away from taluka main town
Jath.
 Area of Madgyal village is 2256
hectares.
 Total population of Madgyal village is
5555;male:2571,female:2264.
 Average annual rainfall
:382.18mm(2002-2012)
Total Watershed Management 28

29.  Literacy rate of madgyal is 60.82%
 Sex ratio is 881 females per 1000
males.
 Major occupation is sheep rearing and
minor occupation is agriculture and
other agro based side business.
 Total water requirement of madgyal is
1,11,100 lit/day.

31.  Perrinial River flowing in the vicinity of
madgyal is krishna (100km).
 Lakes in Jat Taluka are Birnal lake ,
Tilahalli lake
 Lakes are not perennial hence posing
a problem.
Total Watershed Management 31

32.  This minimum requirement of water is
hard to be satisfied all year long.
 Water scarcity arises in the month of
January and lasts up to may.
 These five months tend to be critical
water shortage period .
Total Watershed Management 32

33.  The existing water supply scheme is
driven by lake water and is not
perennial
 There is no such existing rain water
harvesting scheme present in the
village.
 The water available due to rains is not
conserved .
 The dual effect of less rain and no
conservation has led to scarce
Total Watershed Management 33

34.  Hence there is an extreme need of
feasible and sustainable methods of
watershed to this village.
 Through watershed the available rain
water can be usefully led to recharge
resources or directly store and use it
during the water scarcity.
Total Watershed Management 34

35. OBJECTIVES AND SCOPE OF
WORK
 To analyze water resources available
in selected area.
 To know the socio-economic condition
of people.
 To know the water demand and
supply.
 Suggestion of watershed management
techniques.
 Data preparation with the help of GIS.

38. INTRODUCTION
 What is GIS?
 GIS package developed by CSRE, IIT Bombay.
 Software with modules of Map editing, Raster
analysis, Terrain Modeling, Watershed
delineation.
Total Watershed Management 38

39.  GIS analysis.
 GIS analysis is a procedure for looking at geographical
patterns in our data and the releationships between its
features .A GIS is a system of hardware, software and
procedures to facilitate the management, manipulation,
analysis, modelling, representation and display of
georeferenced data to solve complex problems
regarding planning and management of resources. All
GIS software has been designed to handle spatial data,
characterized by information on, connections with
different features and details of non-spatial
characteristics.

42. SCOPE OF ‘GIS’
 Total area of water flowing towards an
outlet point (Pour point).
 Water flows in the direction of the terrain
steepest downhill slope. Streamlines are
orthogonal to the contour lines.
 Drainage line are found along the highest
points of the terrain.

45. METHODOLOGY

46. A. Data collection
1. Physiographical data:
e.g. location, elevation, geology, drainage patterns, slope.
2. Land use and cover types:
e.g. forest, cultivated, water areas.
3. Climate and hydrology:
e.g. Precipitation, temperature, stream flow, evaporation.
4. Socio economic data:
e.g. farming type, production income education.
5. Institutional and culturable data:
e.g. farmers organization, tradition, religions.
6. Management needs:
e.g. environmental impacts, treatment need, infrastructure needs.

47. B. Feasibilities, Alternatives & recommendations
Some of the techniques can be used in watershed
management as given below:
1. Contour bunding
2. Broad beds and furrows
3. Artificial recharge
4. Check dames
5. Terracing
6. Grassland development
7. Tree plantation
8. Lift irrigation schemes
9. Stopping ground water flow
10. Storage of rain water

48. 1. Contour bunding
• Function: To intercept the run off flowing down the
slope by an embankment.

49. 2. Broad beds and furrows
• Function: To control erosion and to conserve soil
moisture in the soil during rainy days.

50. 3. Artificial recharge
 Function : To increase ground water level so that
it can be used in scared condition. To
augment the ground water recharge.
Percolation canal

51. Percolation pond

52. 4. Check dams
 Function: To conserve water by constructing
check dams and use it when required.

53. 5. Bench Terracing
• Function: It helps to bring sloping land into
different level strips to enable cultivation.
