Soil & Water Conservation Module description

Thursday, April 16, 2020 1:53:00 PM

The conservation plan includes three types of treatments: 1) bunding, 2) terracing, 3) trenching. Criteria for selection of treatment types are divided into arable-black soils, arable red and lateritic soils, and non-arable soils. Selection of conservation plan is decided based on land slope, soil depth, texture, gravel, and rainfall. The sequence of activities involved in the selection of different structures and preparation of Soil and Water conservation plan for a given watershed is elaborated in the Implementation Manual for Sujala III project (WDD, 2016)

Note: As per the Technical Manual for Integrated Watershed Development of Institute of Agricultural Technologists, Bangalore Arable land treatments for Black soils are advocated for 1 to 5% Land slope. 1 5-10 and 10-15 slope classes for non-arable lands are not provided in the criteria table at present.

VI = Width x Slope/(100-Slope) for Black soil (batter slope 1:1; horizontal;vertical)
VI =2 X Width x Slope/(200-Slope)-for Red and lateritic soils (batter slope 0.5:1)
HI = Width / VI
Note: For designing the Width = 200 x depth of cut / slope
Depth of cut* = Profile depth x (1-(slope/100))
*minimum depth of cut = 0.3 m OR (Profile depth –(VI/2))
Note: Volume of earth excavation for Terrace strips are estimated using the formula : Q= LxWxD/8
Where, l = Length of the Terrace strip, W= Designed Terrace width, D= Fall between two Terrace strips

Step By Step Process

  • User will select the District, Taluk, Village, and/or Watershed Name and Survey number. User will also be able to enter the XY coordinates as Lat-Long .
  • A query will be executed to find the details about the selected survey number.
  • If user enters XY coordinates, get the information of the selected parcel
  • Finding Slope, Depth, Texture, Gravel, LCC, Land form, for the selected survey number from Land Parcel characteristic table.
  • Fetching average Rainfall for the year.
  • On the basis of LCC and Landform, get soil type which is “Arable soil Red/Lateritic” or “Arable soil black” or “Non arable soil”
  • Search for derived slope against actual slope on the basis of soil type
  • Search for derive soil depth against actual soil depth on the basis of soil type
  • Derived Texture against actual Texture.
  • Get derived Gravel against actual Gravel.
  • Get derived Rainfall against actual rainfall on the basis of Soil type .
  • Find Treatment from on the soiltype and slope, depth, texture, Gravel, and rainfall.
  • Finding horizontal and vertical interval on the basic of treatment and slope and texture and Depth.
  • Finding value of main cross section from on the basis of texture, gravel, slope, depth, VI and HI. Side cross section = 2/3 X Main cross section.
  • Find the length of the structure
    • Length per hectare (m) = 10000 X S/(VI*100)
  • Find the Cost for the Construction of using Treatment, soil, gravel, cross section.
  • Display the result in a table showing the information such as Watershed name, survey number, Area in Hectare as well as information related to Treatment proposed, its length, cost for the main bund, cost for side bund, Total cost and also cost of Waste Weir.
