Drainage characteristics and evolution of the Barind Tract, Bangladesh Bazlar Rashid 1, * , Sultan-Ul-Islam 2 , Badrul Islam

Barind Tract is a terrace (about 11 - 48 m amsl) that is highly internally formed and highly anatomized.

Pliocene - Pleistocene and Holocene red soil and sediments Evolution of terrain in this area is a problem

An area with evidence of structural uplift. This unresolved issue brings various problems such as land use and cities.

Variable dimension development especially for underground water development in the area. Into

This region is experiencing population concentration to meet growing food and water demands

The huge environment got worse. This research is trying to reveal the process that is the cause of the process

Providing information for sustainable development through evolution of road reflecting drainage characteristics

Characteristics of the drainage channel and road evolution research show that the shape of the road is formed

Rivers and valleys on structural control roads are relatively straight, cut and flooded

The river meanders, becomes more localized, forms a pair and an unpaired terrace, and is essentially preemptive. With some valleys

The flow is cut off and beheaded at that place. Rivers flowing from Himalayas changed their morphology, trends,

Nature and interior around the road. N-S river turning south-east and south-west

Lift the slope. All of these are symptoms of activity swelling and newborn structure. During ~

Recent earthquakes and important movements of rivers such as Padma, Yarlung Zangbo, Tista, Atrai

Changes in the landscape of Kosi and other areas also show positive improvement in the region over the past several hundred years.

Barind Tract is a relatively high (about 11 - 48 m amsl) triangular wedge shaped land. It is one of many Pleistocene terraces in Bangladesh in the northwest. Physiology has become one of the important information for planning various development activities. In this paper, we will try to draw the topography of Barind Tract and its surrounding area which have characteristics of drainage channel. SPOT panchromatic images and topographic maps are interpreted visually as this research. The area is divided into three major geographic units and 15 sub-units. The main units are Barind Tract, Channel-floodplain complex, and Himalayan piedmont plain (Tista Fan). The elevation of Barind Tract is about 11 - 48 m Amsl, the flood plain is about 8 - 23 m Amsl, and the height of Tista Fan is about 30 - 45 m Amsl. The eastern part of Barind Tract flattened the terrain slope toward the southwest

Barind Tract is a high-rise terrace of Pleistocene in the northwestern part of Bangladesh (about 11 to 48 m amsl). Earth scientists believe that this phenomenon may have evolved as a result of structural uplift and / or eroded terrain, but no one agrees. This problem represents another problem about the different sizes of groundwater problems in this area. This paper clarifies evolutionary process with the help of underground geology and attempts to provide necessary information on sustainable development in the region. In order to clarify these processes, Pliocene-Pleistocene and Holocene rock formations were constructed by analyzing existing borehole data. In order to distinguish the sedimentary phase from the sedimentary paleoenvironment, lithostratigraphy and geometric analysis have been performed to characterize the sub-environment of the old channel and other rivers. Structural control representing the origin of the elevated Barind Tract
