UNIT-I: Storage Works-Reservoirs
Types of Reservoirs
Reservoirs are essential for water resources management, serving purposes such as irrigation, drinking water supply, and hydroelectric power generation. They can be classified into:
- Natural Reservoirs: Formed by natural processes like lakes and ponds.
- Artificial Reservoirs: Man-made structures created by damming rivers.
Selection of Site for Reservoir
Selecting an appropriate site for a reservoir involves considering:
- Topography: Suitable landforms for dam construction.
- Geology: Stability of rock and soil.
- Hydrology: Availability and flow patterns of water.
- Environmental Impact: Minimizing ecological disruption.
Zones of Storage of a Reservoir
Reservoirs typically have different storage zones:
- Dead Storage: Bottom layer where water cannot be withdrawn by gravity.
- Active Storage: Middle layer used for operational purposes.
- Flood Control Storage: Top layer reserved for flood control.
Reservoir Yield and Capacity Estimation
Estimating the capacity and yield of a reservoir is crucial for effective management. The mass curve method is often used for this purpose.
Reservoir Sedimentation and Life of Reservoir
Sedimentation can reduce the capacity of a reservoir over time. Regular dredging and sediment management are necessary to extend the reservoir’s life.
Types of Dams and Site Selection
Dams can be classified based on their structure and materials, including:
- Gravity Dams
- Arch Dams
- Buttress Dams
The selection of a dam site depends on topography, geology, hydrology, and environmental impact.
UNIT-II: Gravity Dams
Forces Acting on a Gravity Dam
Gravity dams must withstand various forces, such as:
- Water Pressure
- Self-weight
- Earthquake Forces
- Silt Pressure
Causes of Failure
Gravity dams can fail due to:
- Structural weaknesses
- Foundation issues
- Seepage problems
Elementary and Practical Profiles
The design profile of a gravity dam balances structural stability and economic feasibility.
Limiting Height and Factors of Safety
The height of a gravity dam is limited by structural integrity and material strength. Safety factors ensure the dam’s stability.
Stability Analysis
Stability analysis involves checking the dam’s resistance to sliding, overturning, and foundation pressure.
Foundation, Drainage, and Inspection Galleries
Proper foundation treatment, drainage systems, and inspection galleries enhance the dam’s longevity and safety.
UNIT-III: Earth Dams
Types of Earth Dams
Earth dams are categorized based on their structure:
- Homogeneous Dams
- Zoned Dams
- Diaphragm Dams
Causes of Failure
Common failure causes include seepage, piping, and structural instability.
Safe Design Criteria
Design criteria focus on stability, seepage control, and proper construction practices.
Seepage Control Methods
Methods such as cutoff trenches, clay cores, and filters control seepage in earth dams.
UNIT-IV: Spillways
Types of Spillways
Spillways manage water flow over dams and include:
- Ogee Spillways
- Chute Spillways
- Side Channel Spillways
Design Principles of Ogee Spillways
Ogee spillways are designed based on hydraulic principles to ensure smooth water flow.
Spillway Gates
Gates control water flow and include radial, flap, and roller gates.
Energy Dissipaters and Stilling Basins
These structures reduce the energy of flowing water to prevent erosion downstream.
Jump Height Curve and Tail Water Rating Curve
These curves assist in designing energy dissipaters by predicting water behavior.
UNIT-V: Diversion Head Works
Types of Diversion Head Works
Diversion structures, such as weirs and barrages, manage river flow for irrigation and other purposes.
Layout and Components
Key components include silt ejectors, silt excluders, and protection works.
Causes of Failure
Failures often occur due to foundation issues, hydraulic failures, and structural weaknesses.
UNIT-VI: Weirs on Permeable Foundations
Creep Theories
Creep theories by Bligh, Lane, and Khosla help in understanding seepage through weirs.
Design Principles
Design involves calculating uplift pressure, using correction factors, and ensuring stability.
UNIT-VII: Canal Falls and Regulation Works
Types of Falls
Falls help manage water levels in canals. Common types include notch and Sarada Falls.
Design Principles
Design principles focus on hydraulic efficiency and structural stability.
Canal Regulation Works
Regulation works include distributors and head regulators that control water distribution.
Canal Cross Regulators
Cross regulators maintain water levels in main canals, aiding in effective water management.
UNIT-VIII: Cross Drainage Works
Types and Selection Site
Cross drainage works, such as aqueducts and siphon aqueducts, manage the intersection of canals and natural streams.
Design Principles
The design focuses on hydraulic efficiency and structural integrity.
Design of Type II Aqueduct (Under Tunnel)
Type II aqueducts are designed to pass canals under obstructions with minimal impact on flow.
