Study Notes
Water Resources Engineering
- Water resources engineering deals with using water for modern needs (agriculture, industry, domestic, recreation, and environment)
- Earth's water is in the atmosphere, oceans, land, and soil.
- Water is moved by solar energy through evaporation and precipitation.
- The Hydrologic Cycle describes water moving between these locations, with water being conserved.
- Precipitation includes rainfall, snowfall, hail, frost, and dew.
- Runoff is water flowing over land, forming rills, gullies, streams, and rivers.
- A watershed is the area draining into a particular river.
- Reservoirs are natural or artificial water storage areas.
- Evapotranspiration is the process of water vaporizing from water and land surfaces, and from plants (transpiration).
Flood Control
- Floods are excessive water flow exceeding usual levels in a particular area.
- Short-term flood measures provide quick relief:
- Embankments along low-level banks
- Raised platforms for temporary shelter
- Pumping floodwater out of affected areas
- Long-term flood measures aim to regulate flow:
- Construction of reservoirs
- Integrated watershed management (reducing runoff, increasing infiltration)
- Flood forecasts and warnings
Irrigation
- Irrigation is artificially providing water to crops for growth.
- Benefits include increased yields, protecting from famine, and enabling cultivation of better crops.
- This improves economic development, hydropower generation, and provides water for domestic and industrial uses.
Transportation Engineering
- This field involves the efficient movement of people and goods.
- Transport needs vary by the type of transportation (roads, railways, air, or water).
- Transportation impacts the economy in several ways:
- Movement of natural resources
- Allows access to places, resources, or destinations
- Reduces the time needed for travel
- Protects quality of perishable goods
- Decreases the cost of goods, and supports agricultural development.
Traffic Engineering
- Managing traffic flow in urban areas and on roads.
- Types of signs:
- Regulatory (stop, speed limit, etc.)
- Warning (hazards, etc.)
- Guide (directions, etc.)
- Roadways and parking requirements
- Environmental effects of traffic include Air pollution, Noise, Vibration, Severance, and Visual Intrusion.
Highway Engineering
- Planning, designing, building, and maintaining highways.
- The design of highways includes consideration of sight distances for safety.
Railway Engineering
- Design, construction, and operation of railway systems.
- Advantages of rail transport: Suitable for bulk goods transportation, efficient for long distances, often more economical, and relatively safe compared to roadways.
Water Transportation
- Inexpensive, but slower mode of transport.
- Ports, harbors, and docks are essential in water transport.
- Cargo types that are transported by water: Dry bulk, liquid bulk, general cargo, fertilisers, and more.
