P1A 7Flood prediction

Weather Radar

• A system that uses radio waves to detect precipitation and track its movement.

• A device that measures temperature and humidity.

• A tool for predicting earthquakes and volcanic eruptions.

• A network of satellites that monitor global weather patterns.

Topographic Maps

• Maps that show the elevation and shape of the land using contour lines.

• Maps that display only the political boundaries of an area.

• Maps that represent the weather patterns in a region.

• Maps that illustrate the population density of a city.

Return Period

• The average interval of time between flood events of a certain magnitude or greater.

• The time it takes for a river to return to its normal level after a flood.

• The frequency of rainfall in a specific area over a year.

• The duration of a flood event before it recedes.

Inundation Maps

• Maps that show areas that are likely to be flooded, often including the depth and extent of potential flooding.

• Maps that display the topography of a region without any water features.

• Maps that indicate areas of high population density in urban areas.

• Maps that illustrate the migration patterns of wildlife.

Weather Satellites

• Satellites used for GPS navigation

• Satellites equipped with instruments to monitor atmospheric conditions and surface features relevant to weather and flood forecasting.

• Satellites that provide internet connectivity

• Satellites designed for military reconnaissance

Flood Prediction

• The process of forecasting when and where floods are likely to occur, as well as their potential magnitude.

• A method to measure the height of water in rivers and lakes.

• A technique used to divert water from flood-prone areas.

• An analysis of historical weather patterns to predict future rainfall.

Uncertainty in Climate Modelling

• The inherent limitations and unknowns in climate models due to the complexity of the climate system and incomplete data.

• The ability to predict climate changes with absolute certainty.

• The use of historical data to create perfect climate models.

• The simplification of climate models to ignore complex variables.

Flood Hydrographs

• Graphs that show how the discharge or water level of a river changes over time, typically in response to rainfall.

• Graphs that depict the average temperature changes in a region over a year.

• Graphs that illustrate the population growth of a species over time.

• Graphs that represent the changes in wind speed during a storm.

Vegetation

• The plants in a particular area, which can affect soil moisture and runoff.

• A type of soil that is rich in nutrients.

• The process of photosynthesis in plants.

• The climate conditions of a region.

Channel Modifications

• Changes made to a river channel, such as straightening or widening, which can affect water flow and flood risk.

• Alterations to the riverbank vegetation to improve aesthetics.

• Construction of dams to control water levels.

• Implementation of floodplain zoning regulations.
