PPT Downloaded from http://www.pravinkolhe.com/
Site Visit: Water logging
 Site: ‘Additional
Mandavgan Drainage
scheme’, Ganegaon, Tal-
Shirur.
 Observations-
 Well Water Level and
sample collection
 Soil sample collection
 Drain discharge
measurement
8
PPT Downloaded from http://www.pravinkolhe.com/
Water Logging
 We observed 18
wells in the given
catchment and
collected 2 well
water samples.
9
PPT Downloaded from http://www.pravinkolhe.com/
Field Visit: Salinity
 Salts can be
observed on soil.
10
PPT Downloaded from http://www.pravinkolhe.com/
Field Visit: Crop Damage
 Damaged crops are
also observed at site
11
PPT Downloaded from http://www.pravinkolhe.com/
Field Visit: Sample Collection
 24 samples of soil
were collected from 6
auger holes at
following depths-
1. 0-20 cm
2. 20-40cm
3. 40-80cm
4. 80-120cm
12
PPT Downloaded from http://www.pravinkolhe.com/
Tests on Soil and water Samples
 Tests on soil-
 EC: Electrical
Conductivity
 pH
 Hydraulic
Conductivity
 Saturation
 Mechanical Analysis
 Tests on water-
 EC
 pH
13
PPT Downloaded from http://www.pravinkolhe.com/
Test Results
 It is observed that all
the soil samples
were saline. i.e.
EC>3 and pH>8
 The well and drain
water is also saline
with EC>3.
14
PPT Downloaded from http://www.pravinkolhe.com/
Demarcation of affected area
 The points are
marked on the given
catchment map.
 Based on EC values,
contour lines were
marked
 The affected area is
shown on the map
 It is very difficult to
demarcate the area
with only 24 samples.
The accuracy depends
on the number of
samples.
 Remote sensing
technique can be used
to get more accurate
results
15
PPT Downloaded from http://www.pravinkolhe.com/
Remedial Actions proposed
 Preventive measures
 Sprinkler and Drip
Irrigation
 Crop Pattern and crop
rotation
 Leakage Prevention
from canal
 Proper land slope and
drainage arrangement
 Curative measures
 Cross drains
 Controlling Water
Table and Soil
moisture
 Soil Amendment
 Soil leaching
 Bio drainage
16

Remarks and future scope
 Proper drainage is
essential to avoid water
logging
 It is difficult to demarcate
the area on map
accurately.
 Cross drains may be
provided to reduce the
discharge.
 The adjoining land should
be protected from water
logging in future.
 New techniques, like
Remote sensing can be
used to speed up work
accurately.
 Maintenance of existing
drainage scheme is an
important factor.
 Cleaning of natural
nalla.
 Involvement of farmers.
