|
the line that seperates individual drainage basin |
Drainage divide |
|
natural event in an area that is usually dry is submerged under water |
Flood |
|
occurs when a strem's discharge is greater than the capacity of the channel |
riverine flood |
|
characterized by intense, high-velocity torrent of water -occurs in an existing river channel with little to no notice |
Flash Floods |
|
when water overwhelmed in low -lying areas along the coasts |
coastal flooding |
|
when heavy rainfall creates a flood event independent of an overflowing stream |

a wetland with lush trees and vegetation found in low-lying areas beside slow-moving rivers |
swamp |
|
a partly enclosed coastal body of water where freshwaters from stream meets the saltwater from sea |
Estuary |
|
water found in the rock and soil layers beneath surface -largest reservoir of liquid freshwaters on earth -contributes 30.1% of total freshwater |
groundwater |
|
water bearing rock layers -sponge that holds ground water |
Aquifers |
|
total amount of empty pore space in the rock -determines amount of groundwater that aquifer can hold |
