Volume : I, Issue : VII, August - 2011 Variations in the Morphology of Potholes along Kukadi Channel at Nighoj- Maharashtra. Maya Unde And Dadasaheb R. Jawre,Deepali Gadkari Published By : Laxmi Book Publication Abstract : Most of the rivers in Maharashtra have prominent knick points and at such
locations rocky beds of rivers exhibit development of mega potholes. Potholes as
minor landform indicating active erosional phase of the channel are otherwise a
common feature of rocky bed. However when developed on a large scale they
warrant special attention. The details study of the morphology of potholes can help
the understanding of geological controls as well as the flow conditions of the
channel. In the present paper an attempt has been made to study the morphological
variations of the potholes developed by river Kukadi, a tributary of Bhima drainage
system from Western Maharashtra. River Kukadi in its lower reaches attains
7th order of stream and has catchment area of about 2000 km 2. Mega potholes are
located at Nighoj just about 10 km upstream its confluence with river Ghod.
The study area is a rocky stretch of 1.5 km, which forms a boundary
between Pune and Ahmednagar districts of Maharashtra. A prominent knick point
is observed at the intersection of 180 55' N and 740 15' E. At this point, river
Kukadi has incised a deep gorge (depth 40 – 50 m width 10 m and length 200 m)
This particular area is marked with potholes exhibiting various stages of
development. The potholes are confined mainly to the gorge area and their
frequency as well as depth goes on decreasing away from the main channel. Keywords : Article : Cite This Article : Maya Unde And Dadasaheb R. Jawre,Deepali Gadkari, (2011).
