13. Salient Features:
Delineation and codification is done up to microwatersheds level in order to have viable size of
the treatment area having distinct spatial extent and unique national code.
Out of the total 708 microwatersheds surveyed 23 falls under very high and high category.
3 microwatersheds falls under very high priority with 2779 ha (0.37%) and 20 microwatersheds
with 20522 ha (2.75%) comes under high priority categories, requires immediate attention for
proper soil and water conservation.
About 25990 ha area (3.48%) is prone for severe to very serve erosion and 37690 ha (5.05%) is
prone for moderate to severe erosion hazards.
Alluvial plain occupies nearly 35556 ha (4.76%) and 3702 ha (0.5 %) are mapped as a ravinous
lands (10-25% slope) and undulating lands (10-15% slope) respectively, of the total surveyed
area.
Maximum area comes under very deep soils covers an area of 717641 ha (96.07%) of the total
surveyed area.

HOW TO USE SOIL SURVEY REPORT
The report embodies the results of Rapid Reconnaissance Survey conducted for
identification and delineation of priority microwatersheds of 2C6A1 to A9 watershed of
Lower Yamuna FPR Subcatchments falling in eleven districts of Uttar Pradesh State i.e.
Agra, Aligarh, Auraiya, Bulandsahar, Etah, Etawah, Firozabad, Gautam Budh Nagar,
Ghaziabad, Mahamaya Nagar and Mathura and one district of Haryana state i.e. Faridabad.
Covering an area of 7,46,971 ha spread over 708 microwatersheds. The priorities are fixed
on the basis of Runoff Potential Index (RPI). Higher the values of Runoff Potential Index
suggest higher priority and vice versa. The concerned maps on the scale of 1:50,000 are
appended with the report. It also furnishes information on general characteristics of the area
such as, location and extent, physiography, relief, drainage, geology, climate, present
landuse, natural vegetation, water supply and soils of the area.
In the map, each microwatershed is marked by a symbol like 2C6A1a1 etc. where ‘2’
stands for water resource region, ‘2C’ indicates basin , ‘2C6’ for catchment, ‘2C6A’ for
subcatchment, ‘2C6A1’ for watershed, ‘2C6A1a’ for subwatershed and ‘2C6A1a1’ for
microwatershed. Within each microwatershed, the Runoff Potential Mapping Units (RPMUs)
are demarcated according and symbolized by capital English alphabets, based on geological
origin of the land ‘AL’ stands for Alluvium and their further subdivisions are made on the
basis of land and soil characteristics. Each unit connotes a set of physiography, slope,
landuse, soil characteristics such as soil depth, colour, texture, severity of erosion and
management practices. Mapping units are assigned with respective runoff potential weightage
value the priority categorisation of microwatersheds have been done hazard as very high,
high, medium, low and very low priority areas according to runoff potential index value.
The mapping legends furnished in the Table-4 and differentiating characteristics of
each mapping units represented in Table-5.
The details of computation made for determining district wise runoff potential index
of various microwatersheds are furnished in Annexure-I and the information of relative
priority of microwatersheds in descending order of grading are furnished in Annexure-II.
Microwatersheds categorized under very high and high priority are selected for
treatment of degraded lands under these microwatersheds under FPR scheme. Both treatable
and non-treatable lands are occupied by each priority (very high and high category)
microwatersheds. The ratio of treatable and non-treatable lands in a priority microwatershed
vii
varies with the kind, degree and extent of the degraded lands occupied by the some
microwatersheds.
