Dam Design and Flood Management: Hydraulic and Hydrological Methods
Flood Wave Hydrograph
This graphic representation shows the flow evolution in a channel section during a flood. Flow redistribution, due to temporary water storage, decreases peak flow and increases hydrograph base time. Relocation, due to flow travel time, shifts the hydrograph in time. Both phenomena occur simultaneously.
Hydraulic Methods
These methods solve complex unsteady flow equations in open channels, requiring extensive data. They are used in studies needing precise water level information.

ITEM 8
Hydraulic Fluid Level
1. How is the reading of the hydraulic fluid level taken?
It is checked with the engine running and the drive lever height in its highest position. The indicator should be between the minimum and maximum marks.
Conjuntor-Breaker Settings
2. How is the setting adjusted for the conjuntor-breaker?
By using specific springs with washers.
Safety Valve Functioning
3. How can I check the functioning of the safety valve?
Leave the engine running with the height command in the high position
Rear Axle Height & Integral Pneumatic Suspension Systems
Rear Axle Height Adjustment
The body always remains at the factory design height. The system adjusts air pressure in the air springs according to the load, modifying the stiffness coefficient. This achieves a constant frequency and comfort regardless of the load.
Constitution
- Level Transmitter: Located on the rear axle, this sensor measures variations in the distance between the axle and the bodywork.
- Air Springs: Air bags with a sealed internal piston that allows them to fold on their outer perimeter.

Energies of the Future
Cold Fusion
Unlike ordinary fusion, cold fusion is believed to potentially occur at room temperature and produce no hazardous waste. The process involves deuterium in an electrolyte. As deuterium density increases, exceeding a critical value, fusion occurs. Two deuterium nuclei fuse to form a helium nucleus. If unstable, this helium nucleus breaks down, releasing energy.
Fuel Cell
A fuel cell is a small power plant that chemically reacts hydrogen and oxygen to produce electricity,

Problem 1: Football and Handball Teams
In an institute with equal numbers of students, there are football teams (11 players) and handball teams (7 players).
- Suppose it is known that in a randomly chosen team, no two students were born on the same day of the week. How much uncertainty exists about the sport played by the team? Assume there are exactly 52 weeks in a year.
- Repeat the above if it is known that the team consists of students who were born on the same day of the week.
Solution
- None. In the
