Introduction to Hydrology and Water Resources
The Hydrological Cycle
Water is evaporated from the oceans and continents by the direct action of solar energy, or indirectly through transpiration from plants. Evaporated water condenses and forms clouds. Due to gravity, they release the water as precipitation. Water falling over the land surface can take two primary paths: a portion flows over the ground surface (surface runoff) and the other infiltrates the ground and becomes part of the groundwater. Groundwater generally moves very slowly and

Heat Treatments in Metallurgy
Heat treatments are metallurgical processes that regenerate or modify the crystalline structure of metals. This is achieved by subjecting the metal to controlled heating and cooling cycles at specific temperatures and durations.
Annealing
Annealing involves heating the metal above its critical temperature and then slowly cooling it. This process eliminates internal stresses, regenerates the metal’s structure, and enhances ductility. Various annealing types include:

Hydropower
A small number of dams were built specifically for hydropower generation. While hydropower generators do not directly produce emissions of air pollutants, hydropower dams, reservoirs, and the operation of hydropower electric generators can affect the environment. They can obstruct fish migration, change natural water temperatures, river flow characteristics, ecology, and the physical characteristics of the river.

Layers of the Earth
Crust:
A thin, solid layer. There are two types: oceanic and continental.Mantle:
Composed of the rock peridotite. It is solid or rigid, but plastic.Core:
Has a metallic composition, formed by an Fe alloy with Ni-S and other elements. It is liquid.
Continental Crust
Consists mainly of granitic rocks but presents great diversity.
Types of Rocks:
- Sedimentary Rocks: Formed by the compaction and cementation of sediments. Usually occur in strata. Different

The Hydrological Cycle

Due to gravity, they release the water as precipitation. Water falling over the land surface then flows over the ground surface (surface runoff) and other infiltration becomes part of the groundwater. Groundwater moves generally very slowly and is fed from springs (groundwater runoff).
