    Barind Tract (alternately called the Varendra Tract in English and Borendro Bhumi in Bengali) is the largest Pleistocene era physiographic unit in the Bengal Basin. It covers most of Dinajpur , Rangpur , Pabna , Rajshahi , Bogra , and Joypurhat districts of Rajshahi Division and Rangpur Division in Bangladesh .

    Initially 11 selected litholog parameters like (1) fine sand breadth, (2) fine to medium sand breadth, (3) medium sand breadth (4) medium to coarse sand breadth, and (5) coarse sand breadth, (6) percentage of total various sizes sand layer breadth (7) weighted total sand layer breadth (8) continuity of sand layers, (9) coarse sand starting depth an...

    Earlier several attempts have already made to identify ground water potential zone based on various parameters like slope, drainage density, lineament, vegetation cover, land use pattern, morphological structure but all these parameters are related to ground surface (Chowdhury et al. 2010; Jaiswal et al. 2003; Huang et al. 2013). Similarly, undergr...

    Different breadths of sand layers (sand layer classified based on sand size ranging from fine to coarse sand) on selected 17 litholog sites have been used for thematic layer preparation. At first, breadth of different sand layers including fine sand (Fig. 3), fine to moderate sand (Fig. 4), moderate sand (Fig. 5), moderate to coarse sand (Fig. 6) a...

    Total breadth of all sand layers in every litholog site is calculated and also converted to percentage value respect to available drilling litholog depth of the corresponding sites (Fig. 8).

    Weightage has been assigned to each type of sand layer based on their grain size considering their water-bearing capacity. It is assumed that coarse sand layer is more captive in water holding than medium than fine sand layer. So, weight has been assigned as 1 to fine sand, 2 to medium and 3 to coarse sand layer. If type of sand layer is fine to me...

    As lithological composition in the study area reveals, there is alternate arrangement of silt, sand, pebbles and clay layers. Continuity of sand layer is measured dividing total breadth of sand layer of each litholog site by frequency of clay layer (Fig. 10). It is done because a sand layer with 10 m breadth does not carry equal importance if the s...

    Starting depth of first coarse sand layer in every litholog site has been taken into consideration for thematic layer preparation to see proximity of major water-bearing layer to surface on that site (Fig. 12). It is considered because if such layer starts at very proximate zone to surface, chance of reaching infiltrated water to there will be high...

    Total breadth of silt/clay layer above major water-bearing strata (coarse sand layer) in every litholog site has been used for thematic layer preparation because presence of such clay layer above surface can resist infiltration process as well as ground water accretion in the water-holding potential sand layer lying below (Fig. 11). Data related to...

  2. May 29, 2018 · The Barind Tract is an elevated landmass (about 11-48 m amsl) comprised with Pleistocene Terraces and is situated in the northwestern part of Bangladesh. At present, this area faces scarcity of water.

  3. Nov 5, 2021 · Aftabuzzaman et al. carried out detailed investigation on the formation of Barind tract and found that Barind tract consisted of kaolinite, illite and chrysotile with significant amount of opal-CT. The soil sample collected from Nachole and examined by X-ray diffractions showed the composition of kaolinite, illite, quartz and opal-CT while in places it was found chrysotile instead of kaolinite.
