Catalonia’s Natural Resources: Water, Soil, and Vegetation
Humid Catalonia: A Land Shaped by Rainfall
Humid Catalonia is characterized by significant rainfall, exceeding 700 millimeters annually. This climate and the nival regime contribute to Catalonia’s main water reserves. Mediterranean vegetation transitions to deciduous forests (oak, beech) and coniferous forests (fir, pine).
Two Regions of Humid Catalonia
1. Eastern Region: This mountainous area, between the Pyrenees and the coastal range (400-1700 meters), receives 800-1800 millimeters of rainfall yearly.

1. Environmental Sciences
Ecosystems consist of a physical space with environmental factors (temperature, salinity, humidity) and biotic components (living organisms). Humans extract resources from ecosystems, impacting the environment. Environmental sciences study ecosystems from various disciplines (geology, chemistry, biology, law, ethics, etc.).
2. Resource Overexploitation
Natural resources are everything humanity uses from nature. Resources can be non-renewable (limited quantities, e.g., oil)

1. Geomorphology
Geometry and Structure of Relief
Geomorphology aims to reconstruct Earth’s surface history and predict future changes. Landforms are a synthesis of past geological processes.
Morphometry
Morphometry studies landform parameters using mathematical procedures. Any landform can be broken down into simpler shapes, ultimately represented by slopes. This system classifies terrain based on geometric complexity. Morphometric mapping includes slope maps and other specialized maps.

T.9: Nutrition
Nutrition is the process where organisms exchange matter and energy with their environment. Based on nutrition, organisms are classified as:
Autotrophs
Use inorganic matter to create organic matter. They obtain energy from:
- Photosynthesis (light energy, e.g., algae, plants)
- Chemosynthesis (energy from oxidation, e.g., some bacteria)
Heterotrophs
Obtain energy from organic compounds produced by other organisms (e.g., animals, fungi, bacteria).

Pressure and Flow in Pipes
Which of the three deposit outflows lead to less loss of pressure? A pipe transitions with a smooth curve to the vertical parameter of the deposit. From that distance, the delivery point is reached with a pressure drive expressed by H = 2LV / GT (at the beginning of the drive in the check valve pump).

Waste Management
Waste management involves collection, disposal, treatment, and safe storage of hazardous waste.
A. Waste Reduction and Recovery
Techniques to minimize waste and recover resources.
- Source Reduction: Using clean technologies to reduce waste in manufacturing.
- Volume Reduction: Separating waste at the source and physical reduction methods.
- Recovery and Recycling: Reusing waste in manufacturing or the same processes.
B. Waste Processing
Transforming waste to obtain energy or other products.
