|
watershed
|
– An area of land where the surface water and

|
|
water table
|
Water that collects in cracks and pores in
underground soil and rock layers |
|
|
subsidence
|
Sunken land surface due to underlying
compression of earth material as a result of the removal of ground water |
|
|
estuary
|
is a partly enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea.
