Understanding Floodplains and River Systems

What was a key benefit of settling along rivers for early agricultural communities?

• Easy transportation routes

• Nutrient-rich soil from floods

• Protection from predators

• Access to fresh drinking water

What is a hydrograph used for?

• Measuring the depth of a river

• Tracking water discharge over time

• Predicting weather patterns

Why are Java's rivers prone to flooding?

• Flat terrain

• Volcanic rock absorption

• High population density

• Lack of rainfall

What is one major factor contributing to Jakarta's frequent flooding?

• Excessive vegetation

• Lack of urbanization

• Low sea levels

• Its location in a delta region

How do wetlands help in flood management?

• By redirecting river channels

• By increasing river flow

• By absorbing and filtering water

• By preventing rainfall

What is a potential downside of constructing artificial wetlands?

• They are expensive to maintain

• They can lead to increased pollution

• They are less effective than natural wetlands

• Ethical concerns about wetland swapping

What happens when wetlands are paved over?

• Water quality improves

• Flashy flooding increases

• Ecosystems are preserved

• Flooding decreases

What is a common human modification to rivers that can lead to increased flooding?

• Creating ponds

• Planting trees

• Channelizing rivers

• Building bridges

Why is it important to understand your local watershed?
