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.
