Salient Features of Kali Khola
VDC
Armala-1, Kaski
Zone
Gandaki Zone
Tributaries
Ghurkuna Khola, Garlang Khola, Duhuni Khola,
Grami Khola, Majkuna, Tupke Khola, Dhand
Khola etc.
Nature of Khola
Boulder stage, degradation nature, 1.31m bed is
degrading per year (in comparison June, 2011).
Developed Area
Paddy field in right and left bank of Khola but
now newly settlement is rapidly developing.
Total Length of Kali Khola
11 Km.
Catchment Area
41 Sq. Km.

Length of protection
500 m revetments and five bed bars (around
confluence point which is highly critical area)
Total estimate of protection works
(See Annex 3).
Protection by
GI create boxes, RCC Cut-off (bed bar), Geotextile etc.
Kali khola originate in the north part of Pokhara valley from Mahabharat range at Kali Khola
at an elevation of nearly 1962m. The length of Khola is 11 km up to Seti River at Bhalam
Dobilla. It is one of the importtant tributary of the Seti River.

Discharge calculation of Kali Khola
By
1. Dickens formula
Q p = C d A 3/4
Where,
Qp
= Maximum flood discharge in cumecs
A
= Catchment Area
Cd
= Dicken coefficient
Area
= 41 Sq.Km
Cd
=11.5
(11.5 for northern part of India)
Hence Q p
=11.5 *41^ 0.75
=186 m3/sec
2.WECS Method
Q 100 =14.63(A) ^ 0.732
=14.63*41^ 0.732
=211 m3/sec
Adopt 211 m3/sec

Catchment area
= 41 sq. Km
High flood discharge
= 211 m3/sec
River, l-slope
= 1:40, 1:100 (effected area)
Manning’s coefficient
= 0.04
Silt average in bed
= 5mm
Silt factor
= 1.76 (D m ) ^.5
= 1.76*5^0.5
=3.91
2|Page
27. Normal scour depth
= 0.47(Q/F)^1/3
= 0.47*(211/3.91)^0.5
= 1.8 m.
Factor for right angle (K)
= 2.25
= 2.25*1.8
= 4.1m
Average depth of water in high flood = 2.1 m
For launching apron
=2.1*1.5
=3.10 m
Use 4.5m as mattress
Depth of bed bar
=3.10 m
Use 1:2:4 RCC wall having top crest one meter with 1:8 U/S and D/S of wall protect by
gabion crate box in launching apron and add (1x1x1) m. concrete blocks in D/S of wall.
Water way (P)
= 4.75(Q)^0.5%
= 4.75(211)^0.5
=68 m. may be contrast by 80 %

Discharge calculation
By
1. Dickens formula
Q p = C d A 3/4
Where,
Q p = Maximum flood discharge in cumecs
A= Catchment Area(800x200)m
=0.16 Km sq.
C d = Dicken coefficient
Area
= 0.16 Sq.Km.
Cd
=11.5
(11.5 for northern part of India)
Hence, Q p
=11.5 *0.16^ 0.75
=2.909 m3/sec
2. Rain fall Method
Assume, maximum 2500mm rain fall per day
=2500/100*10^4/24*3600
