3. INTRODUCTION
• Tanks have been the lifetime of the rural settlement because they are the traditional source of drinking water
and irrigation in the areas, which depends on monsoon rains for their needs.
• The present study of Chikkanayakanahalli taluk in Tumkur district Karnataka state, the total area of
Chikkanayakanahalli taluk is 1128 sqkm comes within five SOI toposheet, numbers are 57 C/6, 57 C/7, 57
C/10, 57 C/11 and 57 C/15 (scale 1:50000). It has an average elevation of 804 meters .
• The rainwater and the seasonal runoff streams and rivers during monsoon period are stored in the tanks and
this utilized for drinking and irrigation purposes in the later part of the year.
• The major uses of tanks are listed below. Increase in the irrigation facility leading to better crop yield,
recharge of groundwater, which will bring up water table near to the surface. This will benefit water supply
for domestic purpose and irrigation for crops and orchards during post monsoon months.
• Tanks could also be used profitably for aquaculture purpose, water for livestock, animal husbandry activities,
and prevention of flooding and damage to crops during periods of heavy rains in monsoon by storage of
excess water.
• Silt extracted by tanks bed is economically used as manure for agriculture fields and recreation uses like
boating and water sports and developing surrounding area into a park. Tanks have the ability to control
microclimatic condition of their surroundings.

5. STUDY AREA
• The study area of Chikkanayakanahalli taluk is located in the southern part of Tumkur district, Karnataka
state, the taluk covers an area of 1128 Sqkm.
• Chikkanayakanahalli taluk can be divided into physiographic zones - hilly regions, undulating highlands, and
gently sloping pediplains. CNHalli does not have any perennial river flowing through it. The two major
streams -Torehalla and Karetore join to form the river Suvarnamukhi, which flows through the state forest in
the North-East of the taluk. Torehalli River irrigates the area.
• The area is bounded by the latitude North 13 degree 18 minutes to 13 degree 45 minutes and the longitude
East 76 degree 22 minutes to 76 degree 45 minutes of SOI toposheets shown in Map No.1.
• Chikkanayakanahalli (CNHalli) Taluk, Tumkur District, Karnataka area gets an average annual rainfall of
400-450mm.Madalingana Kanive(Mountain Pass) is the only mountain pass located in Chikkanayakanahalli
Taluk, Tumkur District.
• A major part of this taluk is occupied by red sandy soil, red loamy soil along the eastern part. Very small part
in NW part of Chikkanayakanahalli taluk is occupied by mixed red and black soils. Red sandy soils are
suitable for the growth of ragi, jowar, millets and oil seeds under rain fed conditions.
• Chikkanayakanhalli is a Taluk in Tumkur District of Karnataka State, India. Chiknayakanhalli Taluk Head
Quarters is Chikkanayakanhalli town . It belongs to Bangalore Division. Tiptur City , Arasikere City , Sira
City , Tumkur City are the nearby Cities to Chiknayakanhalli.
• Chikkanayakanhalli consist of 392 Villages and 29 Panchayats . Harogondanahalli is the smallest Village and
Huliyar is the biggest Village . It is in the 804 m elevation(altitude)

6. OBJECTIVES
• Tanks information system is helpful to know tank capacity, recharge rate, to know the necessary improvement techniques
and to assess the impact of climate change, land use change, human activities on the tank ecosystem and water
availability.
• To plan and implement appropriate interventions for tank restoration, conservation, and development.
• The objective of the present study is to develop a GIS based Agricultural management of tank irrigation information
system to facilitate the planning, operation and management of tank system and to monitor and manage the water
resources in tanks efficiently and effectively.
• GIS based information system is capable of generating outputs in the form of maps, tables and graphs that will help the
irrigation engineers, agriculturalists, farmers and Government officials to monitor the performance of the tank at any
place and time to take necessary steps to manage the resources effectively.
• This information can be recorded and stored as different layers in GIS in the form of spatial and non-spatial data. GIS
has the capability of integrating and analyzing spatial, non-spatial and multi-layered information available in different
formats in framing various strategies for agricultural management for socio-economic development.
• By using software like ERDAS Imagine 10.1 and Arc Pro GIS software the tanks are digitized and change deduction has
been done using recent digital satellite data to compare the present status of the tank. The tank information system is
further help full to know about tank quantity, quality, rate of recharge and improvement techniques.
• Assessment of physicochemical and biological water quality of tanks.

8. METHODOLOGY
• In the present study, the maps showing tank details have been prepared from digital data of Resourcesat,
Landsat and Castosat of LISS III and SOI Topomaps. These satellite image and Toposheets have been
geo-referenced using ERDAS Imagine professional and Arc GIS pro software.
• The tanks have been delineated using SOI Toposheets on 1:50,000 scale. Field work has been carried out
and the tanks areas are considered for the analyses are summarized in detail in table no 1. Arc GIS
software and ERDAS Imgine have been used for digitization and computational purpose and also for the
output generation is shown in Fig No.1 & 2. The extraction and processing of Remote Sensing data is
shown in Fig No.3.

9. RESULTS AND DISCUSSIONS
• The tank information system is analysed by the Arc GIS Pro and ERDAS Professional Software and
compiled the results by above methodology as shown in Table No.1 of Survey of India Toposheet data
of the year 2010.
TABLE No.1: Categorization of Tanks as per SOI Toposheet data

10. • Out of the 247 tanks the 77.77% of the tanks categorized under the minor tanks, 16.59% of tanks
categorized under the small tanks, 4.59% of tanks are medium tanks, remaining 1.21% of tanks as large and
very large tanks.
• The digitization of tanks is show in Map No.2. Borana Kanive place is between two mountains, water
which comes from Suvarna Mukhi river, is the source for this dam. Borana Kanive Dam is an Gravity and
Masonry Dam.
• The maximum height is 39 feet and total storage capacity is 2.42 tmc. Dam receives water from
overflowing water of 375 lakes from Tiptur and Chikkanayakanahalli taluk.
• Borana Kanive Dam was built during the rule of Mysore Maharaja Sri Chamarajendra Wadiyar X by
Col.Michanil in the year 1888-1892. Borana Kanive Dam is an oldest dam compared to Marikanive Dam
and KRS Dam. It’s total area is 3204.23 acres and it is the largest tank in Chikkanayakanahalli taluk.

15. CHANGE DETECTION USING REMOTE SENSING DATA
• Change in tank area detection based on RS images is conducive to the acquisition of land use and
tank development information.
• In this paper, confronting the challenges brought by the multi-source RS images and multi-
objective application scenarios. Total area of Chikkanayakanahalli taluk has an total area of
2,78,734.9 acres out of which 11,307.04 acres is covered by tanks that is 4.05% of total area as per
2010 SOI toposheet record. On comparison of toposheet data with recent remote sensing data of
present year change in tank area as shown in Table No.3.

16. TANK CAPACITY DATA OF MINOR IRRIGATION TANKS
• As per Minor Irrigation Department data there are 37 tanks which fall under minor irrigation department
whose area lies between 40 to 2000 hectares and their water storage capacity is noted in the below Table
No.4.
Table No.4: Tank Capacity Data Of Minor Irrigation Tanks

17. CONCLUSIONS
• According to the digitized tank measurement of SOI Toposheet data all 247 tanks, classified as minor,
small, medium, large, very large tanks based on their water spread area. From Arc GIS Pro software
environment can be quickly analyze data easy and predications will made for the further development.
• The above information is to meet a demand of groundwater scarcity to improves surface water resources,
the rainfall in the taluk is annually is average 400-450 mm but we need to improve the tanks for the
surface water conservation, if surface water conservation is takes place the automatically groundwater
recharge will improves the groundwater level is increases considerably, with this to serve the future
water scarcity problem for the further generation.
• From the calculated catchment area and water spread area, amount of water inflow runoff into the tank is
calculated and also further percolation and evaporation losses to be calculated and also water budget
equation is calculated to entire taluk.
• This data can also make use of Groundwater Estimation Committee.
