Abstract The morphometric analysis coupled with
remote sensing and geographical information system
techniques evaluates various valuable parameters for the
watershed development plan of drought-prone Andhale
watershed of Pune district, Maharashtra. The upper part of
the watershed shows parallel–sub parallel and rectilinear
drainage patterns indicative of structural control, whereas
the lower part shows dendritic drainage pattern revealing
the homogeneity in texture and lack of structural control.
The elongated shape of this basin is indicated by values of
form factor, circulatory ratio and elongation ratio. The
mean bifurcation ratio is observed to be 4.65 indicating the
watershed is less affected by structural disturbances, and
drainage pattern is not much inﬂuenced by geological
structures. The hypsometric integral obtained for Andhale
watershed is 0.316 indicating maturity stage of the basin.
The longitudinal proﬁle depicts steep gradient at the origin
but it gradually ﬂattens out as the river erodes its base
level. The high values of drainage density, stream fre-
quency, inﬁltration number and drainage texture indicate
that the study area is underlain by impermeable rocks
responsible for high runoff. Thus, the results of this anal-
ysis would be useful in determining the effect of catchment
characteristics such as size, shape, slope of the catchment
on runoff vis-a-vis the scope for water harvesting.

Watershed development and management programmes in
hard rock terrain play a key role in establishing the demand
and supply side equilibrium. Assessment of drainage and
their relative parameters quantitatively give valuable inputs
in preparing the plan for the sustainable water resource
development and management. Morphometric and hypso-
metric analysis is widely used to assess the drainage char-
acteristics of the river basins (Rao and Babu 1995; Pakhmode
et al. 2003; Sreedevi et al. 2005; John et al. 2006; Manu and
Anirudhan 2008; Magesh et al. 2011). Morphometric and
hypsometric assessment of a river basin has of late been used
for applied purposes. It has also been found to be a useful tool
to delineate the glacial till covered overburden material,
identify areas prone to ﬂash ﬂoods, evaluate the hydrological
nature of the rocks exposed within the drainage basin,
understand the interrelationship between rock type, struc-
tures and drainage network and watershed prioritization,
etc., (Esper 2008; Pankaj and Kumar 2009; Bali et al. 2012).
The drainage characteristics of a basin reveal the prevailing
climatic conditions, rock structure, relief, runoff, perme-
ability of the rocks and tectonic framework of a basin.
Rainfall, lithology and slope are the preliminary determi-
nants of surface water functioning at the watershed scale
(Mesa 2006, Machiwal and Jha 2014).
Remote sensing and geographical information system
(RS-GIS) techniques are in vogue for assessing various
morphometric and hypsometric parameters of the drainage
basin/watershed, as they provide a user friendly environ-
ment and a powerful tool for manipulation and analysis of
spatial information (Gangalakunta 2004; Godchild and
Haining 2004; Grohmann et al. 2007; Korkalainen et al.
2007; Yu and Wei 2008; Hlaing et al. 2008; Javed et al.
2009; Umrikar et al. 2013).
