Burdwan University Previous Year Question Paper

Explanation:
The Idukki project is a major hydroelectric facility in India, built across two rivers in hilly terrain using an arch dam design. It plays a crucial role in regional Electricity supply and irrigation.

Hydroelectric projects are constructed where rivers have high flow and potential energy. Arch dams require narrow valleys and strong rock foundations, which helps narrow down the location. Studying topography and comparing other major hydroelectric projects enables identification of the state.

Think of the project as a giant battery storing energy from falling water in a mountainous region.

Understanding Idukki involves knowledge of India’s key dams, river valleys, and states with hilly terrain suitable for arch dams.

Explanation:
The Salal Project is one of India’s early river valley hydroelectric projects, designed for Electricity generation. Its location depends on river flow, valley structure, and regional topography.

Hydroelectric projects require a river with high discharge and suitable valleys. The Salal project lies on a Himalayan river in northern India. Comparing northern states with major river valley projects and reviewing historical construction data helps identify the region.

Like a watermill on a fast-flowing river, the project harnesses energy efficiently.

Identifying the Salal Project requires understanding river valley hydroelectric projects in Himalayan terrain.

Explanation:
The Loktak project is a hydroelectric facility built on a freshwater lake and river system. Its location depends on water availability, regional topography, and energy needs.

Projects like this are often situated where lakes or rivers provide consistent flow for turbines. The hilly terrain, combined with proximity to regional energy demands, guides the site selection. By comparing states with major lake-fed hydroelectric projects, the correct state can be inferred.

Similar to using a water reservoir to feed a turbine continuously, the project converts stored water into Electricity efficiently.

Understanding Loktak involves knowledge of hydroelectric sites built on lakes and rivers in India.

Explanation:
The Bhakra Nangal Project is a major multipurpose river valley project. The river it spans determines irrigation, hydroelectric capacity, and regional water management.

River valley projects require strong water flow for generating Electricity and supplying irrigation. Identifying the river involves examining northern Indian rivers with suitable valley features, historical dam sites, and hydrology studies.

It can be visualized like placing a dam on a fast-flowing river to store water and generate Electricity, much like filling a reservoir and releasing water through turbines.

Understanding Bhakra Nangal requires knowledge of northern Indian rivers, valley structures, and multipurpose dam design.

Explanation:
The Koyna project is a major hydroelectric facility situated in a hilly region, utilizing river water for Electricity generation. Its location depends on topography and river flow.

Projects like this require valleys with strong geological formations and consistent water supply. By analyzing India’s river valley projects in western and central regions, one can narrow down the state. Historical construction records provide additional clues.

Like storing energy in a water reservoir to power turbines, the project efficiently converts flowing water into Electricity.

Understanding Koyna involves India’s hydroelectric sites, valley Geography, and river systems.

Explanation:
The Nathpa Jhakri project is a large hydroelectric dam built on a high-gradient river in mountainous terrain. Its state depends on river origin, flow, and surrounding topography.

Such projects require strong water currents, steep valleys, and geological stability. Northern Indian states with Himalayan rivers are likely candidates. Reviewing topography, river catchment, and hydroelectric development patterns helps locate the project.

Like channeling fast river water to spin turbines, the project transforms kinetic energy into Electricity efficiently.

Understanding Nathpa Jhakri requires familiarity with Himalayan river projects and hydroelectric engineering.

Explanation:
The Periyar Hydropower Project is located where river flow and hilly terrain allow effective Electricity generation. Its site selection depends on catchment area, topography, and river discharge.

Projects like this are built in regions with reliable water sources and valleys suitable for dams. Knowledge of regional hydroelectric projects and river-fed reservoirs aids identification.

Think of it as a natural battery, where stored water releases energy through turbines.

Understanding Periyar requires knowledge of India’s river systems and hydroelectric project locations.

Explanation:
The Sardar Sarovar Project is a multipurpose river valley project. The river it spans is critical for hydroelectric power, irrigation, and water management.

River valley projects need consistent water flow and suitable valley topography. Analyzing rivers in western and central India with major dam projects helps identify the correct river.

Like a controlled water release through turbines, the dam converts potential energy into Electricity while managing water resources.

Understanding Sardar Sarovar involves knowledge of major Indian river valley projects and hydrology.
