Jor | 9.2 Collateral Information 
1B | 
The collateral information includes the information on slope, aspect, altitude and 
socio-economic conditions. As mentioned earlier, the information on slope was 
generated from topographical sheets by taking 20m contour interval as a base. 
Most of the area except for mesa, inselberg and pediment is very gently to 
gently sloping whereas a few pockets of nearly level lands occur in the buried 
in pediplain (Fig.-5).

to The information on land and water resources of the watershed, thus generated, 
an enables the policy makers and administrators having an overview of the 
of potentials and limitations of the natural resources of entire watershed and 
nd eventually helps identifying potential and critical areas requiring detailed 
ich investigation. Based on information on land and water resources, terrain 
| is attributes like slope, aspect, altitude, quantum and distribution of rainfall, an 
integration key was developed after scanning the spatial data on land and water 
resources on a CONTEX FSS 800 black and white and white scanner, and 
studying them in a GIS environment using ARC/INFO software, along with 
collateral information, for generation of optimal land use plan for sustainable 
in development of the watershed.

he For optimal utilization of available land and water resources, intensive 
in, agriculture has been recommended in the buried pediplain with fine—textured 
as moderately deep to deep soils with good to moderate ground water potential. 
rg, Whereas fuelwood and fodder plantation has been recommended in 3,198ha of 
ith land comprising 18.5796 of the watershed for providing protective cover to 
ter denudational slope with coarse-textured, shallow and gravelly soils; agro- 
to forestry/rain-fed agro-horticulture/horticulture has been proposed in 9,299ha of 
tal land covering28.38% of the test site following soil conservation measures in the 
ts, lower plateau with moderately deep to deep black soils (Fig.-6).

ed bunding, construction of check walls across gullies have been advocated (Fig.-7). 
is, Such check dams not only help arresting soil loss but contribute significantly to 
is groundwater recharge. In addition, the construction of percolation tanks has also 
or been recommended at suitable locations which are exclusively meant for 
ing groundwater recharge.
