General Notes Flashcards
What is hydrology
The science of distribution and movement of water
What is the greatest natural hazard to people
Flooding (40%)
What percentage of people is at frequent risk of floods
30%
What happened by the year 2000
Half of the people living in the developing world did not have access to safe drinking water
Why do people not have access to safe drinking water
Poor spatial distribution or water resource
Poorly developed water supply
Pollution of existing or potential supplies
What does water control
The migration of nitrates that can make lakes eutrophic, acid rain, landfill leachates and movement of sediment
What are hydrological processes
The pathways, rates and patterns of water in the biosphere and geosphere
What is the case study for the study of water catchment processes
Th physical impacts of rainforest logging in Borneo
What is the case study for subsurface flow processes
Pollutant migration associated with the construction of a nuclear repository - nirex borehole
What is a water resource
Total amount of water available in the environment
What is water supply
Quantity of water absorbed from the environment
What is eutrophication
Nitrogen or phosphorus enrichment of rivers and lakes that result in algal blooms that depleted oxygen levels
What is leachates
Mostly dissolved substances moving within subsurface water flow
What leads to landslides
Changes how water moves in groundwater, loses in-channel water quality (turbidity)
Example of water supply abstractions
Lahad Datu water works in Borneo
