15 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. Total

production To increase infiltration of rainwater. Total Watershed
Management 21 22. To protect and enhance the water
resourceoriginating in the watershed.To check soil erosion and to
reduce the effect ofsediment yield on the watershed. To improve and
increase the production oftimbers, fodder and wild life resource.
To enhance the ground water recharge,wherever applicableTotal

Wankute is located high inSahyadri mountain range ofMaharashtra. It
was dry and nearly barren place in1990 and water was supplied with
thehelp of tankers. Problem was, the rainfall was limited. With the
help of one NGO, theyimplemented various techniques ofWSM like
construction of bunds,checkdams,vegetation,plantation. Total
Watershed Management 24 25. Now, water table has increased, no
needof tankers. Overall employment increased. All types of crops
can be cultivated. No shortage of potable water and nowaterborne
diseases. Built new community hall,2 schools,public health center
etc. WSM have contributed to overalldevelopment of village very
well.Total Watershed Management 25 26. NEED Total Watershed
Management 26 27. NEED OF WATERSHEDMANAGEMENT IN MADGYAL The
precipitation intensity andcharacteristic vary drastically in
Sanglidistrict. In the parts of Krishna river basin andvicinity the
rainfall statistics arecomparatively good and enough torecharge
major catchment. On the contrary, the eastern region ismore drought
prone and isconsistently under water scarcecondition. Total

Taluka,district Sangli. Coordinates are Latitude 170256.94 N
Longitude 75 138.14 E It is 21.8 km away from taluka main townJath.
Area of Madgyal village is 2256hectares. Total population of
Madgyal village is5555;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
1000males. Major occupation is sheep rearing andminor occupation is
agriculture andother agro based side business. Total water
requirement of madgyal is1,11,100 lit/day.Total Watershed
Management 29 30. Total Watershed Management 30 31. Perrinial River
flowing in the vicinity ofmadgyal is krishna (100km). Lakes in Jat
Taluka are Birnal lake ,Tilahalli lake Lakes are not perennial
hence posinga problem.Total Watershed Management 31 32. This
minimum requirement of water ishard to be satisfied all year long.
Water scarcity arises in the month ofJanuary and lasts up to may.
These five months tend to be criticalwater shortage period . Total
Watershed Management 32 33. The existing water supply scheme
isdriven by lake water and is notperennial There is no such
existing rain waterharvesting scheme present in thevillage. The
water available due to rains is notconserved . The dual effect of
less rain and noconservation has led to scarceTotal Watershed
Management 33 34. Hence there is an extreme need offeasible and
sustainable methods ofwatershed to this village. Through watershed
the available rainwater can be usefully led to rechargeresources or
directly store and use itduring the water scarcity.Total Watershed
Management 34 35. OBJECTIVES AND SCOPE OFWORK To analyze water
resources availablein selected area. To know the socio-economic
conditionof people. To know the water demand andsupply. Suggestion
of watershed managementtechniques. Data preparation with the help
of GIS. Total Watershed Management 35 36. COMPONENTS OF DESIGN

INTRODUCTION What is GIS? GIS package developed by CSRE, IIT
Bombay. Software with modules of Map editing, Rasteranalysis,
Terrain Modeling, Watersheddelineation.Total Watershed Management
38 39. GIS analysis. GIS analysis is a procedure for looking at
geographicalpatterns in our data and the releationships between
itsfeatures .A GIS is a system of hardware, software andprocedures
to facilitate the management, manipulation,analysis, modelling,
representation and display ofgeoreferenced data to solve complex
problemsregarding planning and management of resources. AllGIS
software has been designed to handle spatial data,characterized by
information on, connections withdifferent features and details of
non-spatialcharacteristics. Total Watershed Management 39 40. Total
Watershed Management 41 41. SCOPE OF GIS Total area of water
flowing towards anoutlet point (Pour point). Water flows in the
direction of the terrainsteepest downhill slope. Streamlines
areorthogonal to the contour lines. Drainage line are found along
the highestpoints of the terrain.Total Watershed Management 42 42.
TOPO SHEET Total Watershed Management 44 43. METHODOLOGY 44. A.
Data collection1. 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. 45. B.
Feasibilities, Alternatives & recommendations Some of the
techniques can be used in watershed management as given
below:1.Contour bunding2.Broad beds and furrows3.Artificial
recharge4.Check dames5.Terracing6.Grassland development7.Tree
plantation8.Lift irrigation schemes9.Stopping ground water flow10.
Storage of rain water11. Connecting to other water body etc. 46. 1.
Contour bunding Function: To intercept the run off flowing down
theslope by an embankment. 47. 2. Broad beds and furrows Function:
To control erosion and to conserve soilmoisture in the soil during
rainy days. 48. 3. Artificial recharge Function : To increase
ground water level so thatit can be used in scared condition.
Toaugment the ground water recharge. Percolation canal 49.
Percolation pond 50. 4. Check dams Function: To conserve water by
constructingcheck dams and use it when required. 51. 5. Bench
Terracing Function: It helps to bring sloping land intodifferent
level strips to enable cultivation. 52. Watershed
Management-Recommendation & Future Scope 53. Recommendation
Analysis of primary data and its correlation withthe ground water
data collected.Attractthe resources and funds to tackle
priorityactions to improve watershed and lake health.Inform
stakeholders and guide actions well intothefuture 54. Securing
required resources.Engaging stakeholder groups and the public on
the Terms of Reference and obtaining their input into the
Plan.Identifying existing data, defining datagaps, data collection
and analysis.Community Consultation to identify the priority issues
impacting water quality and associated mitigation measures. 55.
Future ScopeSolution to expensive bulk water
transferImprovepredictability.Providing drinking water for rural
people.Incrementalincrease in water availability. 56.
Implementation, good practices, success/failure reasons and then
related it with groundwater data obtained. Saving in time for
availing domestic water 57. WORK DONE TO DATETRAININGWORKSHOP AT
