ABSTRACT
Environmental appraisal is a complex process involving the interplay of geological,
hydrological and several other environmental parameters including geospatial data of an urban area.
This study aims to delineate the suitable landfill sites of municipal & industrial wastes in the city of
Mysore, Karnataka, India through Remote Sensing (RS) and Geographic information system (GIS)
techniques along with Ground Truth Check (GTC). Mysore urban exhibits flat to gently undulating
topography with an elevation varying from 700-725 m above MSL with a gentle slope towards the
south. The perennial Cauvery River flows from west to east direction in the northern parts of the
study area. The spectral signature of satellite images (7 bands) of IRS-1D, PAN+LISS-III including
geo-spatial data from Survey of India (SoI) toposheet (scale-1:50,000) were processed using GIS
(spatial analysis) to classify the study area into two zones i.e., buffer zone and core zone. Mysore is
one of the major cities in Karnataka producing nearly 600 tons of solid wastes everyday that need
more landfill sites in future due to increase in their volume. The existing waste treatment plant in the
study area is operating within the core zone above a major lineament affecting the groundwater
resource, human health and surrounding environment. The integration of Remote Sensing, GIS
analysis and GPS survey demarcates seven alternative locations to the existing landfill site,
considering the environmental, biophysical and socio-economical factors.
Keywords: Soil, Lineament, Landfill Siting, Mysore City, RS & GIS.

1. INTRODUCTION
The rapid growth of population in a city demands for an increase in waste disposal and also
larger area for disposal of effluent & toxic wastes from different sources (Allen et al, 1997; Azadhe
and Basavarajappa, 2010, 2011). This becomes a major environmental issue posing threats to the
existence of human being and surrounding environment (Kontos et al, 2005). Applications of
Remote Sensing and GIS provide the alternative method of minimizing operational costs (Ogra,
2003; Kyessi & Mwakalinga, 2009) and digital data bank for long-term monitoring in suitable site
selection and fast evaluation (Miles et al, 1999). Buffering is a spatial (proximity) analysis that
generates a polygon around a point, line or polygon theme by locating boundaries at a specified
distance (Adeofun et al, 2006 & Sani et al, 2010). Using spatial analysis, a buffer zone of 25km
radius was created around the study area from the city centre (Krishna-Raja circle) for extensive
study. Soil and lineament form the basic geological structures which are easily identifiable in the
satellite imagery and helps in understanding the nature of lithology, to delineate the groundwater
potential zones and also in landfill siting. The main factors considered to keep away the landfill sites
are indicated as lakes, ponds, rivers, groundwater table, air quality index, geology, fault line,
elevation, land use, habitation, highways and sensitive sites (Sumathi, 2006; Siddique et al, 1996;
Basavarajappa et al, 2012). Mysore city is named as second cleanest city in 2010 by Nationwide
Union Urban Development Ministry (NUUDM). Nearly 200 tons of solid waste is treated at the
sewage farm (existing treatment plant at Vidhyaranyapuram) daily to produce compost, remaining
nearly about 400 tons of garbage dumped as untreated. There will be a need to create a new landfill
sites every few years due to increase in waste generation. The currently operating landfill site in the
study area is located within the core zone and is rapidly running out of space. Hence, new landfill
sites are needed urgently in the outskirts of core zone. The landfill sites should have sufficient
capacity to meet the current and projected waste to be deposited within the next 10years.
2. STUDY AREA
The study area is located between 120 18’ 31” N and 760 39’ 11” E with 25km radius from
the centre of the city (Krishna-Raja Circle) (Fig.1). The total areal extent is 83.4 km2. The study area
is classified into two zones viz., buffer zone and core zone for environmental appraisal. The
extensive study was carried out in buffer zone (20.51 km2) while core zone (13.42 km2) for intensive
study using visual image interpretation and thematic layers. Buffer zone also covers a small part of
Mandya district in the northern part of the study area. The majority of the area is covered by
agricultural fields with moderate plantations. The main crops grown are sugarcane, maize, ragi,
paddy, jowar, vegetables and flowering plants etc.
3. CLIMATE AND RAINFALL
The temperature ranges from 16.40C (Jan) to 340C (April). The maximum annual rainfall in
the study area was 1295mm (year-1903) and the minimum was 412mm (year-1967). The normal
annual rainfall exceeds 832mm (2012). The average wind velocity is 10.6 km/hr and the average
annual humidity is 65%.

4. METHODS & MATERIALS
Factors considered for suitable landfill site are geological structure, bedrock and overburden
lithology. Hydrological parameters including infiltration, percolation rates, pathways of rainwater
passing through subsurfaces and hydrogeological characteristics. Topographic height above MSL, as
surface slopes, exposure to the elements, particularly rain and wind were considered. Economic
distances from waste sources, road networks, site access, management costs arising from the physical
characteristics of the site etc (Allen & McCarthy, 1991).
• Satellite Imagery – IRS-1D, PAN+LISS III, TM & ETM+ (year-2000), Path-144 & Row 51 with
52m resolution (USGS).
• Toposheets - TIFF Images of 57D/11, 57D/12, 57D/15, 57D/16 (scale-1:50,000)
• GIS Tools - ERDAS IMAGINE 9.2 & ArcGIS 9.2.
• GPS - A field survey using GPS (Garmin-12) was conducted to check the conditions of the
suggested alternative sites and exact locations.
5. SOIL
Mapping of soil in vegetated terrain and deriving information of soil types from satellite
imagery is one of the advantages of Remote Sensing. To obtain more than three types of soil in a
study, it demands wider area coverage. Leachate migration from the landfill could be a potential
source of surface and sub-surface water contaminations. Clay soil is one of the best sites for landfill
siting for the prevention of leachate problems. Clay pits are more suitable for depression type
landfills whereas sand gravel pits should be avoided according to permeability, except when the
bottom formations are impermeable (Azadhe et al, 2009). Following are the soil types identified in
the study area (Fig.2).
Clay soil is deep and moderately, well drained and slight salinity in particles. Clay-Mixed soil
is deep and moderately, well drained with clayey soils of valleys with problems of drainage and
slight salinity in particles. It is associated with deep, imperfectly drained, clayey over sandy soils.
Clay-Skeletal soil is found to be very deep which is well-drained and has clayey soils on undulating
interfluves with slight erosion. It is associated with shallow to excessively drained, gravelly clay soil
which is moderately eroded. Rocky Land soil is associated with deep and moderately, gravelly clay
soil on gently sloping interfluves and also slightly eroded in particles.

6. LINEAMENTS
Faults are geological structures that cause limitation for siting a landfill (Gemitzi et al, 2007).
The landfill site should be kept away at least about 100-200 m from any faults, fissures, joints,
stream/lakes and other shear zones to avoid environmental damages of any area. Lineaments were
digitized from the satellite imagery and are classified into minor, medium & major lineaments. The
average direction of lineaments are towards NW, NE and SW direction; two major lineaments
located towards NE and SW direction in the study area (fig. 3 & 4), (Basavarajappa et al, 2007,
2012).

7. FACTORS CONSIDERED
The factors affect or interplay with other important parameters that should kept away at least
about 100 m for landfill criteria (Church, 2002) such as environmental, biophysical, ecological
(plant, animal habitat and bio-diversity), geology, elevation, land use, (climatic, local microclimate,
air quality index, wind velocity, humidity, temperature), geotechnical (foundation characteristics,
side slope stability relation, site design, mitigation of risks), socio-economic (noise, smell, dust,
181

litter, vermin, insects, birds, visual impact, proximity to housing, domestic waterwells, highways,
habitations, sensitive sites, distance from waste source, site access, management cost and physical
characteristics of the site) (Chang et al, 2008; Rahman et al, 2008; Lunkapis 2010; Nishant 2010).
8. INTEGRATION OF LAYERS
Integration of thematic map prepared from Remote Sensing & GIS, collateral data using GPS
survey yields more accurate and effective results. The combinations of thematic layers were
analyzed, interpreted, integrated and the following seven points were obtained as best sites having
equal significance for proper way of scientific waste disposal in the buffer zone. Overlay and buffer
analysis have been performed in ArcGIS 9.2. Landfill should be avoided in northern part due to the
presence of major (Cauvery) lineament, however the waste disposal is possible in southern part due
to the gneissic terrain with gentle slope area (Fig.5).

9. RESULTS AND DISCUSSIONS
Excellent groundwater potential zones are found in northern region (Cauvery river) while
excellent to moderate found towards eastern and southern regions (Kabini river). The southern region
is much drier when compared to the irrigation land in northern region. The existing landfill site is
operating within the core zone just above a major lineament, affecting the groundwater table by
adding effluents and toxic materials present in the huge wastes when heavy rainfall occurs (Azadhe &
182

Basavarajappa, 2012). Selection of soils (clay) with less impermeability is an important factor for
landfill.
Transportation, natural drainage, vegetation cover, topography, geology, lineament, soil, and
built-up area should be considered as important factors to keep away the newly selected disposal
sites. The city wastes like medicare & biomedical wastes (from 8-10 major hospitals), chemical
wastes (industries & factories) and green wastes (vegetables, cattle wastes & municipal wastes),
should be treated individually in the suggested alternate sites due to their adverse effect on soil,
water which is a difficult task to prevent. Waste management becomes less flexible due to the
seasonal fluctuation in its volume. Environmental appraisal on waste disposal is more appropriate,
based on geological, geotechnical, Remote
Sensing, GIS and GPS survey study for rocky soil of gneissic terrains like Mysore city. All
seven points were demarcated based on the study of advent high-tech tool of Remote Sensing, GIS
and GPS survey to avoid most of the water bodies and seepage areas through the fractures and
lineament zones around Mysore city (Basavarajappa et al, 2012).
10. CONCLUSIONS

Integration of Remote Sensing and GIS based approach provides a digital data bank for longterm monitor reducing the time, cost of site selection and fast evaluation. All the suggested sites were
clay-rich environment and bare lands, based on the present investigation data.
Solid wastes consist of everyday items such as product packaging, furniture, clothing, bottles,
food scraps, newspapers, appliances, paint and batteries. Burning these, can generate energy
reducing the volume of waste by up to 87%. The city waste should go from open dump to recycling
at the source directly. Sorting of waste from city at the source level, allows the incineration of
residuals minimizing the environmental burden. The crushed materials may used as good quality
construction bricks by recycling methods. The best benefits of landfill is to dig a basin shape
depression at certain depth to deposit huge solid wastes, it should be sealed in all directions except
providing a pipe to generate GAS, BOOM energy to produce compost in low cost and other benefit
to prevents greenhouse gases being emitted into the atmosphere. Implementation of recycling
scheme where the papers are collected separately improves the material recovery of eco-friendly.
The existing waste treatment plant is located within the core zone and operating above a major
lineament blocking the movement of groundwater in the study area.
At least 4 MW of electricity can be generated daily from 100 tons of solid waste with 5 acres
of land in any one of the newly selected site, by adopting an advanced version of pyrolysis
technology, which is an eco-friendly and cost-effective tool. Majority of the solid waste from
construction and demolition of old buildings should be sorted, crushed using machines, later may
used as good quality construction bricks by recycling methods.
The existing treatment plant was set up in vidyaranyapuram in 1996, which produces
unbearable stink emanating from these wastes proving a health hazard to the locals. Residents of JP
Nagar, Vishveshwara Nagar and Vidyaranyapuram have been suffering from different ailments like
nausea, eye infection, giddiness, headache and asthma. The existing treatment plant also burns
plastic which emits bad smell and carbon dioxide. The presence of the plant is also said to have
resulted in students dropping out of schools in the vicinity. Students are also under health risks. With
accumulation of 12 lakh tons of garbage, over 2 lakh people living in the radius of 3 km are
adversely affected. The existing treatment plant is located about 6 km from the centre of the study
area with an area of 5 hectares. There is also a small vermin-composting is operational producing 5
tons/per day of solid wastes in the famous Mysore (Chamaraja Wodeyar) zoo.
