Urban and Engineering Geology PDF Print E-mail

The urban area brings together millions of people of different educational and cultural level in a very confined area. Most of the city dwellers have no idea about the geology, engineering geological properties and environmental processes and the possible natural hazard susceptibility of the area. To meet the increased demand of expanding urban population and infrastructure expansion the natural geomorphic setting of the urban and suburbs areas are changing very fast without proper planning, ignoring the geo-scientific factors. In the past many unplanned even planned urban areas have been developed without considering their geological and ground condition. The efficient application of geological data and engineering methods in civil infrastructure development and urban landuse planning can only reduce the risk of loss of human life and property. Identifying the source of natural hazards and calculating their vulnerability the natural hazards could be managed in planned way.


The branch of Urban & Engineering Geology is continuing to give support in all these aspect. This branch is headed by a Director (Geologist by profession) under one of the two divisions of GSB. This branch is subdivided into three sections that are 1) Urban Geology and 3D geological modelling, 2) Engineering Geology and 3) Engineering Geology laboratory. Generally a Deputy Director heads a section and conduct the individual field / research program under the direct supervision of the branch chief.




Main responsibilities of the branch are to carry out geological and geotechnical exploration and produce the Engineering and Urban Geological maps and generate systematic data of the developing and urban areas of the country for the use of infrastructure developer, planner, and policy makers as well as for the general people. General objective is to collect and compile the geological and geo-scientific data for the use of engineering infrastructure development practice purposes. Study and assessment of the vulnerable and susceptible infrastructures and urban areas to natural hazards based on engineering geological condition and urban development practices. Provide guideline to reduce the risk and hazard potential in planned and cost-effective way in placing the risk elements in safer places with proper engineering method to reduce the loss of human life and property. The specific objectives are:


To prepare geo-scientific and engineering data base,

To provide the government and non-government agencies or individuals the Urban and Engineering geological information to meet their demand in planning and development activities.

To provide necessary assistance in urban developments, risk and damage reduction during Natural Hazards anywhere in the country,

To perform research work on Geoscientific and geotechnical issues, earth processes and natural hazard potentials and their relation to the urbanization activities in the urban areas of the country.

3-dimentional Geological-Engineering Geological modelling, for the efficient application of geological data and engineering methods in urban infrastructure planning to reduce the risk of loss of human life and property also for the better visualization and easily understanding of complex geo-scientific data.

To motivate public, planner, developers and policy makers, and generate awareness about the need of use geo-scientific and engineering geological data.


Besides the regular objectives, this branch also provides service along with a committee to the government to control the private land developer. As per the government rules every private land developer needs clearance from GSB for geological suitability of the proposed land development project.




Current Activities


Title: Engineering Geological Mapping and Geological Information for Building Ground (GIBG) of Cox’s Bazar Town up to Inani beach area and surrounding’s Cox’s Bazar district


Area: Coastal area of Cox’s Bazar Town upto Inani area, Cox’s Bazar district.


Objective: The overall objective of this project is to create engineering geological maps and database for the coastal area of

rapidly developing urban area in Cox’s Bazar. The overall idea is to establish a 3- dimensional geological model and thus to

suggest the safe and low hazards areas for future development. This project will also give idea to identify the coastal erosion

activities, landslide susceptibility and thus to suggest for safer urban activities
