Abstract
Groundwater is one of the most valuable natural resources and supports human health,
economic development and ecological diversity. Timely and reliable information on
occurrence, movement and deterioration of groundwater is a pre-requisite for demanded
water quantity with satisfying quality. Artificial groundwater recharge plays a vital role in
sustainable management of groundwater resources. The study area has been facing severe
water scarcity due to scanty precipitation and intensive agriculture during the last few years.
The present study was carried out to assess groundwater resources and its development
through artificial recharge in Mehsana district of Gujarat state. The result shows that the
stage of groundwater development is more than 100%, so groundwater falls under over
exploited category. An attempt is made to identify the artificial groundwater recharge sites
using remote sensing (RS) and geographic information system (GIS) techniques. As per the
available details pertaining to recharge structures, total 2708 structures are already in
existing conditions to augment 228.46 Mm3
/year water to the aquifer, while 224 suitable sites
are identified through which rest 9.54 Mm3
/year surface water can be recharged. The results
of the study can be used to formulate an efficient groundwater management plan for
sustainable utilization of limited groundwater resources.
Keywords: Groundwater resources, artificial recharge, geographical information systems,
remote sensing, recharge sites
INTRODUCTION
In many parts of the Mehsana district,
groundwater development has already reached
a critical stage, resulting in acute scarcity of
the resource. Overdevelopment of the
groundwater resources results in declining
groundwater levels, shortage in water supply,
intrusion of saline water in coastal areas and
increased pumping lifts necessitating
deepening of groundwater abstraction
structures [1]. Recharge is very complex and
slow process and is unable to keep pace with
the excessive and continued exploitation of
groundwater resources. This has resulted in
depletion of groundwater resources in the area.
The surface water resources of the district are
very limited. Groundwater is the main source
of irrigation, about 93% of the area is irrigated
by groundwater [2]. A systematic planning of
groundwater development using modern
techniques is essential for the proper
utilization and management of this precious
groundwater resource. Artificial recharge aims
at augmenting the natural replenishment of
groundwater storage by some method of
construction, spreading of water, or by
artificially changing natural conditions. It is
useful for reducing overdraft, conserving
surface runoff, and increasing available
groundwater supplies. As groundwater is
dynamic and interdisciplinary in nature, an
integrated approach of remote sensing and GIS
technique is very useful in various
groundwater management studies. Remote
sensing provides diverse datasets over a large
inaccessible area that can be efficiently
handled and analyzed in a GIS framework [3].
North Gujarat is naturally endowed with one

An Assessment of CartoDEM v1 over National Capital
Region of India

Abstract
The most reliable and common source of elevation information for a given region has always
been topo-sheet maps. However, other sources of elevation are now freely available with the
advancement in the technology. SRTM DEM and ASTER DEM are the best examples of such
freely available elevation sources. Still there is constantly a demand of better elevation data
among the users. Recently, National Remote Sensing Center, India released CartoDEM v1. It
is freely available with a horizontal resolution of 30 m and covers pan India. It is always
challenging to ascertain the quality and accuracy of freely available DEMs. This paper, over
National Capital Region (NCR) of India, assesses the quality of the CartoDEM v1 using 127
surveyed spot-heights and bench-marks captured from 1:50,000 scale SOI topo-sheet maps
and carries out a comparison with SRTM DEM v4 and ASTER DEM v2. It is demonstrated
that mean error is 1.34 m and absolute RMSE of CartoDEM is 2.83 m. The relative RMSE
with SRTM DEM is 2.77 m and ASTERDEM, is 3.34 m. The trend of hydrological sinks in
CartoDEM is similar to SRTM DEM and ASTERDEM. The drainage network delineated
shows better match with channels in actual on ground and catchment divides are clearly
demarcated by CartoDEM. The achieved results develop confidence in the quality of
CartoDEM over NCR in India and opens alternatives to use CartoDEM over publicly
available SRTM DEM and ASTER DEM. Also, it opens avenues for research either on version
1 or on other versions of CartoDEM for its better usability over Indian region.
Keywords: CartoDEM v1, NCR in India, SRTM DEM and ASTER DEM
INTRODUCTION
A digital elevation model (DEM) is a digital
3D representation of a terrain surface [1]. It is
represented as a mesh of squares (raster or
grid) or as a vector-based triangular irregular
network (TIN). The DEM can be divided into
digital surface model (DSM) and digital
terrain model (DTM). The DSM contains
heights of artifacts, infrastructure and
vegetation whereas DTM contains only bare
earth elevation [2]. The DEM could be
generated through different techniques such as
lidar, photogrammetry, land surveying, etc.
[3]. A DSM may be useful for landscape
modeling, city modeling and visualization
applications [4–6] while a DTM is required for
flood or drainage modeling, land-use studies,
geological applications, and similar other
applications [7].
The conventional method of developing the
elevation data through contour and surveyed
spot-heights is quite lengthy and tedious.
These maps need utmost care in scanning and
geo-referencing along with digitization of the
contours and capturing the bench-marks
require good amount of the precision.
SRTM DEM Version 4
The SRTM elevation data (DEM) resulted
from a collaborative effort led by the national
aeronautics and space administration (NASA)
and the national geospatial-intelligence agency
(NGA), as well as the participation of the
German and Italian space agencies, to generate
a near-global DEM of the earth using radar
interferometry.
The SRTM DEM covers almost exactly 80%
of Earth’s total landmass [8, 9]. The SRTM
DEMs, at many places, have ‘no-data’ gaps
where there are water bodies and huge
shadows; due to which its implementation is
critically restricted in many domains, for
example, hydrological modeling [10]. Though
due to its widespread spatial coverage, SRTM

Abstract
In Nanded township, generally the water is drawn from the shallow aquifers. As the soil
thickness is more and because of its permeable and porous nature, the effluent water
percolates into the ground and contaminates the groundwater. In this assessment, the
physicochemical parameters like pH, calcium, chloride, alkalinity, total hardness, and salinity
are determined by following the standard procedures given by Trivedi and Goel (1986). The
sources of these contaminants are the industries, septic tank disposal, agricultural effluents,
waste disposals, etc.
Keywords: Aquifers, effluents, contaminants, physicochemical parameters
INTRODUCTION
Groundwater pollution may be defined as the
artificial induced degradation of natural
groundwater quality. Pollution can impair the
use of water and can create hazards to public
health through toxicity or through spreading of
diseases. Most pollution originates from the
disposal of wastewater following the use of
water for any of the wide variety of purposes.
Thus, a large number of sources and causes
can modify from groundwater quality, ranging
from drainage system, septic tank, agriculture
discharges of water in excess amount. In
contact with surface water pollution,
subsurface water also gets polluted. With
growing importance of groundwater resources,
efforts are increasing to prevent, reduce and
removal of groundwater pollution [1, 2].
The possible pollutants in groundwater are
virtually limitless. The sources and causes of
groundwater pollution are closely associated
with human use of water. The principle
sources come under four categories, i.e.,
municipal, industrial, agricultural and
miscellaneous [1]. But the disposal of refuse
(domestic and industrial solid waste) is the
major source for the groundwater pollution as
well as a major environmental problem [1–3].
In this part of Nanded township, the
groundwater is contaminated mostly due to
excessive discharge and there is no artificial
resource to recharge the groundwater.
STUDY AREA
Nanded district in between 18º15ʹN to 19º55ʹN
latitude and 77º7ʹE to 78º15ʹE longitude,
covering an area of about 10,502 km2
(Figure 1). As this area is too vast, the study
area is restricted to part of Nanded city only,
which constitutes the area from railway line
southwards to the main Godavari bridge
between the main through fares (Figure 2), i.e.
the railway over bridge (Shivaji Nagar) to
watch tower chowk and railway station to
main gurudwara road to watch tower chowk.
The area is approximately 3000250 m in size.
This part of the city is considered to be having
higher population density and maximum
flooding problems.
METHODOLOGY
During the field survey, 20 bore wells with
sufficient discharge were identified for a
detailed study. Water samples were collected
from these 20 bore wells (Figure 2, locations 1
to 20) during post monsoon (November, 1998)
season. The bore-wells from which samples
have been collected, were being extensively
used for drinking and other domestic purposes.
The water samples were analyzed for the
physicochemical parameters as per the

Abstract
The piano key weir is a nonlinear free flow type weir with small foundation width. There are
many geometrical parameters which influence the discharge capacity of the piano key weir.
As in Labyrinth weir, the piano key weir is zigzagged in a plan to increase the crest length.
Overhanging on both sides reduces the foundation width of such weir. To investigate the
effects of key-shape variation of piano key weirs on flow capacity of piano key weir,
laboratory experiments were performed on the models in the laboratory. Each model was
tested at various discharges, flow depths were measured on the upstream and downstream
side for the purpose. Experimental results depict the influence of the crest length
magnification ratio and key width ratio of the discharge capacity.
Keywords: Piano key weir, Crest length magnification ratio, Key width ratio
INTRODUCTION
The ground surface water is normally collected
by the reservoir of dams. The performance is
influenced by two major problems: The first,
day to day decreasing storage capacity of the
dam due to gradual increase of silting and the
second, referred to risk of inadequacy of the
flow capacity of the spillway. The details
regarding the occurrence of a failure of the
dams showed that nearly one third of the total
numbers of failure of the dam are due to the
insufficient discharge capacity of the spillway.
Many existing spillways are presently
undersized and required rectification. For the
weir, head-discharge relationship, Eq. (1), the
discharge capacity of weir (Q) influenced by
water head on crest and the weir length.
Where, Q = Cd

Cd is the discharge coefficient, g is the
gravitational constant, L is the crest length and
Ht is the total head (Piezometric head (H) plus
velocity head (V2
/2g)) measured on the weir
crest. Normally, there are two options for
increasing the discharge capacity of a
nongated weir spillway when restricted by a
maximum pool elevation;
1. Lengthening the spillway width,
2. Reducing the crest elevation of the
spillway.
Taking into consideration the dam geometry
and economic point of view, increase in length
of the spillway is not a pragmatic resolution.
Besides lowering the crest elevation decreases
the storage capacity of the dam, which is
infeasible.
In general, the nonlinear weir represents the
most viable option. In recent times, the piano
key weir is a newly developed option to linear
weir designs [1]. The piano key weir has been
studied and tested for the last five years by a
no-profit Association Hydrocoop with a view
to avoid the above drawbacks [2]. Hydrocoop-
France in association with the Laboratory
Hydraulic Developments and Environment of
the University of Biskra (Algeria) developed a
new shape of nonlinear weir, piano key
weir [3].
This innovative type of weir has the benefit
that it is used for existing as well as new dams.
Its construction is simple, easy and can be
carried out by local resources available in
country [4]. The piano key weir will minimize

Abstract
In a country over 125 million, we are proudly an agricultural based economy, wherein 51% of
population is indulged in any business related to somehow with agriculture. Of course, we
still are in a developing stage as far as methodologies or their implementation is concerned.
But surely somewhere we have started focusing on modern techniques and strategies to
improve pattern, productivity, profit and all. The two vital natural resources required for the
agricultural production of any country are soil and water. The net productivity of crops
depends on the proper management and utilization of these natural resources. To overcome
the water related problems, extensive care should be given to the operation and management
of reservoirs and watersheds. Hydrological modelling is a commonly used tool to estimate the
basin’s hydrological response to precipitation. It allows to predict the hydrologic response to
various watershed management practices and to have a better understanding of the impacts of
these practices. This paper highlights a study of lake involving computation of runoff maps
and there curve numbers. The selected watershed is been observed for the runoff pattern and
the rainfall variations throughout the season. It revealed that, urbanization has led to increase
in surface runoff, where as there is decrease in infiltration. This results in increase of surface
runoff and contributes more to the natural streams. As a result, the discharge and the surface
area of the river increased. These discussed changes seriously lead to water management
issues.

INTRODUCTION
Hydrology means the science of water. It is the
science that deals with the occurrence,
circulation and distribution of water of the
earth and the earth’s atmosphere. The word
‘Hydrology’ has been derived from two Greek
words ‘Hydro’, i.e., water and ‘logos’, i.e.,
science. It can be defined as “A science which
deals with the properties, distribution and
circulation of water on the surface of the land,
in the soil, in the underlying rocks and also in
the atmosphere mainly in the form of moisture
or water atmosphere mainly in the form of
water vapour and in the form of water droplets
during rainfall or in the solid form of snow
particles during snowfalls [1].”
Urbanization leads to change in land use. It
decreases vegetation and increases
concretization. Rain water runoff increases due
to concretization. This changes the water-
drainage patterns and rainfall-runoff pattern.
This eventually results in rise of water
management issues in a long period of time [2].
GIS is a computer based system used to capture,
store, analyse, update and display data. GIS
handle mainly two classes of data which are
spatial data, identifying the location and
topography of map and attribute data, identifying
the characteristics of these feature [3].
CASE STUDY
Study area is a part of Watershed. The major
water body in this watershed is Pawana Lake.
Pawana Lake is essentially an artificial lake
brought into existence due to the Pawana dam.
Pawana River originates from the Western
Ghats. The river is reported to be severely
populated, causing the civic activists to blame
the governing body for not taking appropriate
steps to limit the degradation.
