Study Notes
Dr. Karl von Terzaghi
- Recognized as the Father of Soil Mechanics, laying foundational principles in civil engineering.
Bridge-Pier Loading
- Four types of bridge-pier loading include:
- Vertical Loads: Forces acting straight down.
- Inclined Loads: Forces acting at an angle.
- Inclined Tensions: Tension forces acting at an angle.
- Horizontal Thrusts: Forces acting horizontally, impacting stability.
Bridge Abutments
- Abutments must support at least part of the structural loads of a bridge.
- Those located on sloping ground need special design considerations for stability.
Sir Sanford Fleming
- A designer known for contributions to civil engineering, predicting safety measures in construction.
Grouting
- A critical technique in civil engineering, especially for building dam foundations.
- Developed by Albert François to improve structural integrity by filling gaps.
Water Supply
- Involves the study of water distribution, movement, and quality.
- The fall of rain serves as the primary source for most water supplies.
Water Conduit and Cistern
- Water Conduit: Channels or pipes that transport water.
- Cistern: An underground reservoir for storing water.
Water Cycle Dynamics
- Evaporation occurs when sunlight heats water.
- Surface runoff refers to water flowing over land surfaces.
- Vegetation intercepts some rainfall, impacting water availability.
- Percolation involves water absorption into the soil.
Rainfall Records and Stream Gauging
- Records provide data on the frequency, intensity, and duration of rainfall.
- Stream gauging measures discharge rates in bodies of water.
Hard Water
- Contains high concentrations of dissolved minerals, classified into two types:
- Temporary Hard Water: Removable by boiling.
- Permanent Hard Water: Remains unchanged when boiled.
Soft Water
- Characterized by low mineral content, making it more suitable for certain household uses.
Specific Uses of Hard and Soft Water
-
Hard Water:
- Drinking and Cooking
- Gardening
-
Soft Water:
- Cleaning and Laundry
- Bathing, Appliances, and Plumbing
Porous Stratum
- Refers to layers of rock capable of holding and transmitting water.
Water Management Concepts
- Water Storage: Dams built across rivers or streams for reservoir creation.
- Water Collection: Reservoirs gather significant amounts of water.
- Water Treatment: Processes ensure safety before water reaches consumers.
Groundwater Recharge
- Natural Recharge: Groundwater replenishment through natural processes.
- Artificial Recharge: Intentional efforts to increase groundwater levels.
- Various methods for recharge include:
- Spreading Basins: Surface flooding techniques.
- Recharge Pits and Shafts: Used effectively with low-permeability lenses.
