Objective of Visit
construction, components and working as well as
working of hydropower plant.
VISIT OUTCOMES:
• Students are able to understand the different components of Dam.
• Students are able to understand the Design and Working of Dam and Canal
Structure.
Introduction:
During the visit to Chaskaman Dam, a comprehensive assessment was conducted on the canal
structures associated with the dam. This report aims to provide a detailed overview of the canal
structures' introduction, structure and capacity, construction, operation and functioning, and
conclude with key observations.
Structure and Capacity:
1. The canal structures at Chaskaman Dam comprise a network of channels designed for
water distribution to designated areas for irrigation purposes.
2. The canals are constructed with reinforced concrete linings to prevent water seepage
and ensure efficient conveyance.
3. The capacity of the canal structures is designed to accommodate approximately 214
million cubic meters (MCM) of water, which is approved for irrigation.
4. The left canal is a prominent feature, extending for 144 kilometers. It serves as a
primary water distribution network, facilitating controlled water flow to various areas
for irrigation and agricultural activities.
5. The subsidiary canal, measuring 14 kilometers in length, supplements the left canal. It
contributes to optimizing water usage and enhancing overall water distribution
efficiency in the region.
The canal structures at Chaskaman Dam demonstrate a well-designed and engineered system,
capable of effectively delivering water for irrigation purposes. The reinforced concrete linings
ensure the durability and efficiency of the canals, while the capacity is tailored to meet the
approved irrigation needs. The inclusion of the left canal and the subsidiary canal further
enhances the water distribution capabilities, allowing for effective utilization of water
resources in the surrounding areas.
Construction:
1. Planning and Design: The construction of the canal structures in Chaskaman Dam
involved thorough planning and design to ensure efficient water distribution for
irrigation purposes. Factors such as topography, land usage, and water demand were
considered during the planning phase.
2. Earthwork Excavation: The construction process began with extensive earthwork
excavation to create the network of canals. Excavators and bulldozers were used to
remove soil and shape the terrain according to the planned canal alignments.
3. Reinforced Concrete Linings: To prevent water seepage and ensure efficient water
conveyance, the canal structures were lined with reinforced concrete. Steel bars, also
known as rebar, were used to reinforce the concrete, enhancing its strength and
durability.
4. Canal Construction: The canals were constructed using formwork, which is a temporary
mold or structure that holds the concrete in place until it hardens. The formwork was
carefully positioned along the canal banks, and concrete was poured into the molds to
create the canal walls.
5. Regulating Gates and Sluice Gates: The canal structures were equipped with regulating
gates and sluice gates to control the flow of water. Regulating gates allow for adjustable
water flow, while sluice gates are used for diversion or cut-off purposes. These gates
were carefully installed at strategic points along the canals to facilitate effective water
distribution.
6. Cross-Drainage Structures: Cross-drainage structures such as culverts or underpasses
were constructed at appropriate locations along the canals. These structures allow water
to flow freely beneath roads, railways, or other obstacles, ensuring uninterrupted water
conveyance.
7. Length and Width: The canal structures at Chaskaman Dam consist of canals with
significant lengths and widths, designed to meet the water distribution requirements.
The exact lengths and widths can vary based on the specific canal, but they are designed
to accommodate the water flow and irrigation needs.
8. Capacity and Storage: The canal structures have a capacity to distribute approximately
214 million cubic meters (MCM) of water from the reservoir to the designated irrigation
areas. This capacity ensures that a substantial volume of water can be efficiently
conveyed for agricultural purposes, supporting local irrigation needs.
9. Quality Control Measures: Quality control measures were implemented during
construction to ensure the durability and reliability of the canal structures. Regular
inspections, concrete strength testing, and adherence to engineering specifications were
conducted to maintain construction standards.
Operation and Functioning:
1. Water Flow Management: The operation of the canal structures in Chaskaman Dam
involves managing the flow of water from the reservoir to the designated irrigation
areas. Regulating gates and sluice gates installed along the canals are used to control
the volume of water and regulate its distribution.
2. Water Distribution: The canal structures facilitate the distribution of water to different
agricultural fields and irrigation areas. The regulating gates allow for adjustable water
flow, ensuring that each area receives the required amount of water based on
agricultural needs and crop requirements.
3. Irrigation Scheduling: To ensure equitable water distribution and efficient water usage,
irrigation scheduling is implemented. Water users, such as farmers and agricultural
cooperatives, are allocated specific time slots for water usage. This scheduling helps
optimize water resources and prevents wastage.
4. Maintenance and Cleaning: Regular maintenance and cleaning activities are conducted
to ensure the smooth operation of the canal structures. Sediment and debris can
accumulate over time, affecting water flow and efficiency. Regular cleaning helps
prevent blockages and maintains the capacity of the canals.
5. Water Monitoring: The water flow and distribution in the canal structures are closely
monitored to ensure effective operation. Water levels and flow rates are monitored using
sensors and gauges to assess the performance of the canals and adjust water distribution
as needed.
6. Repair and Rehabilitation: Periodic repairs and rehabilitation are carried out to address
any damages or wear and tear in the canal structures. This includes repairing any cracks
or leaks in the concrete lining, maintaining the gates and control mechanisms, and
ensuring overall structural integrity.
7. Water Conservation Measures: Efforts are made to promote water conservation and
efficient water use within the canal structures. This may include implementing water-
saving techniques such as drip irrigation or encouraging farmers to adopt water-
efficient practices.
the operation and functioning of the canal structures in Chaskaman Dam are aimed at ensuring
efficient water distribution, promoting equitable access to water resources, and supporting
agricultural activities in the region. Through proper management, maintenance, and
stakeholder engagement, the canal structures contribute to sustainable irrigation practices and
enhance agricultural productivity.
