Water Resources

Understanding Global and South African Water Management

CAPS Grade 10 Geography

This section covers the main water-resources work in Grade 10 Geography. You will move from global water distribution to South African water supply, floods, and practical ways of managing water in a water-scarce country.

Water Resources Topics

Water is essential for life, but it is not available equally everywhere. These topics help you connect global patterns to South African examples such as drought, dams, inter-basin transfer schemes, and flood risk.

Water in the World

Global water distribution, the hydrological cycle, and the world's oceans

Explore Global Water

Water in South Africa

Water availability, major rivers, dams, and challenges in a water-stressed nation

Explore SA Water

Water Management in SA

Strategies, challenges, and sustainable solutions for water security

Explore Management

Floods

Causes, types, impacts, and management of flood disasters

Quick Check: What do you know

Test your understanding of water resources before diving into the topics.

A) Approximately 97% of Earth's water is salt water

B) Most fresh water is found in rivers and lakes

C) South Africa has abundant water resources

D) Floods only have natural causes

Hint: Think about global water distribution percentages.

Key Concepts in Water Resources

Core Themes

Water Distribution

Where is water

97% salt water, 3% fresh water (mostly in ice caps)

Hydrological Cycle

How does water move

Evaporation, condensation, precipitation, infiltration, runoff

Water Management

How do we manage water

Inter-basin transfers, dams, legislation, conservation

Geographical Tools & Methods

GIS in Water Management

Digital mapping

Mapping wetlands, siting dams, monitoring water resources

Flood Risk Maps

Hazard assessment

Identifying areas vulnerable to flooding

River Basin Maps

Watershed analysis

Understanding drainage patterns and water flow

Drought Monitoring

Climate data

Tracking rainfall patterns and water scarcity

What You'll Learn
