Contextualization

Hydrography is a branch of Geography that studies the waters of the planet, including rivers, lakes, oceans, glaciers, groundwater, and atmospheric water. Understanding the different water systems of the world, whether continental or oceanic, is essential to comprehend the distribution, circulation, and arrangement of water on our planet, as well as the various implications that this knowledge holds, whether for the environment, societies, or global economies.

One of the most important subdisciplines of hydrography is the study of rivers, which are natural waterways for rainwater and a significant water resource essential for the life of countless species on the planet, including humans. Similarly, the oceans, which cover more than two-thirds of the Earth's surface, play a critical role in regulating the global climate and provide habitat for millions of species.

The hydrography of the world has a very practical and relevant application in our daily lives. In addition to water supply, a fundamental source for human survival, it also has a direct influence on agriculture through irrigation, energy generation through hydroelectric power plants, water transportation, fishing, and even tourism.

Companies and governments worldwide rely on hydrographic studies to make high-impact decisions, ranging from sustainable water management to the implementation of infrastructure and energy projects. In a scenario of growing concern about climate change, a deep understanding of global water systems is vital to predict and mitigate future harmful effects.

Practical Activity

Title: Hydrographic Cartography: Mapping the Waterways of the World

Project Objective:

The objective of this project is for students to research, analyze, and create a map of the world's hydrography, highlighting its main features, including the largest rivers, lakes, and watersheds globally, as well as the oceans. The project also requires students to investigate and present socio-environmental and economic issues related to hydrography.

Detailed Project Description:

Students, in groups of 3 to 5, will work on developing presentations and a large map illustrating the main water systems of the world. This will be done through in-depth research, which should address four main topics: rivers, lakes, oceans, and watersheds. In addition, students should relate the study to the socio-environmental and economic impact, exploring how hydrography affects both the global economy and local communities.

Required Materials:

• Computer with internet access for research.
• Painting and drawing materials (pens, colored pencils, etc).
• Large sheets of paper for the map.

Detailed Step-by-Step Guide for Activity Execution:

1. Divide students into groups of 3 to 5 members.
2. Each group should choose one of the proposed themes (rivers, lakes, oceans, or watersheds) to start their research.
3. Students should research their chosen theme, seeking to understand the global distribution and main characteristics of these water systems. They should also analyze the related socio-environmental and economic impacts.
4. After the research, groups should synthesize the information and plan how to represent their findings on the map.
5. With the collected information, students should build the map, drawing and coloring the main water systems of the world according to each group's theme.
6. In addition to cartographic information, students should include small explanatory notes on the map, highlighting important facts or characteristics of the hydrography they researched.
7. After completing the map, each group should prepare a presentation for the rest of the class, explaining their findings and insights.

Project Deliverables:

The final project deliverables will be:

• The World Hydrographic Map: This map, collaboratively built by all groups, should be accurate, informative, and aesthetically pleasing.
• Presentation: Each group will give an oral presentation to the class, explaining their research and contributions to the map.
• Final Report: Each group should prepare a detailed written report, including: an Introduction (with the contextualization of the theme, relevance, real-world application, and project objectives), Development (explaining the theory, detailing the activity, indicating the methodology used, and presenting and discussing the results obtained), Conclusion (highlighting the learnings and conclusions about the project), and the Bibliography used.

In this final report, it is important for students to demonstrate a deep understanding of the studied topic and be able to relate their findings to socio-environmental and economic issues. The report should also demonstrate the students' ability to work in a team.
