## Relevant types:

Name | Type | Definition | Description
--- | --- | --- | ---
Aquifer_C | Feature Type | An underground layer of water-bearing permeable rock or unconsolidated materials (for example: gravel, sand, silt, or clay). | It may yield economically significant quantities of groundwater to wells and springs.
Aquifer_P | Feature Type | An underground layer of water-bearing permeable rock or unconsolidated materials (for example: gravel, sand, silt, or clay). | It may yield economically significant quantities of groundwater to wells and springs.
Aquifer_S | Feature Type | An underground layer of water-bearing permeable rock or unconsolidated materials (for example: gravel, sand, silt, or clay). | It may yield economically significant quantities of groundwater to wells and springs.
Gully_C | Feature Type | A deep ditch or channel cut into the terrain that results from erosion due to surface water runoff. | -
Gully_S | Feature Type | A deep ditch or channel cut into the terrain that results from erosion due to surface water runoff. | -
InlandWaterbodyBank_C | Feature Type | The region along the edge of an inland water body that lies between the water and the first break in slope. | -
InlandWaterbodyBank_S | Feature Type | The region along the edge of an inland water body that lies between the water and the first break in slope. | -
InlandWaterbody_C | Feature Type | A body of water that is entirely surrounded by land. | It may occur in a natural terrain depression in which water collects, or may be impounded by a dam, or formed by its bed being hollowed out of the soil, or formed by embanking and/or damming up a natural hollow (for example: by a beaver dam). Inland waterbodies have many uses such as: a source of water for irrigation, industrial processes, human consumption, and recreation. Impounded inland waterbodies may also be used for flood control.
InlandWaterbody_P | Feature Type | A body of water that is entirely surrounded by land. | It may occur in a natural terrain depression in which water collects, or may be impounded by a dam, or formed by its bed being hollowed out of the soil, or formed by embanking and/or damming up a natural hollow (for example: by a beaver dam). Inland waterbodies have many uses such as: a source of water for irrigation, industrial processes, human consumption, and recreation. Impounded inland waterbodies may also be used for flood control.
InlandWaterbody_S | Feature Type | A body of water that is entirely surrounded by land. | It may occur in a natural terrain depression in which water collects, or may be impounded by a dam, or formed by its bed being hollowed out of the soil, or formed by embanking and/or damming up a natural hollow (for example: by a beaver dam). Inland waterbodies have many uses such as: a source of water for irrigation, industrial processes, human consumption, and recreation. Impounded inland waterbodies may also be used for flood control.
InundatedLand_S | Feature Type | A tract that is exceptionally covered by water, excluding tidal waters. | It may be caused by either uncontrolled inundation (for example: flooding due to a river overflowing its banks or low-lying regions accumulating standing water following severe rainfall) or controlled inundation (for example: flooded by the regulation of the level of a reservoir).
LandSubjectToInundation_S | Feature Type | A tract periodically covered by flood water, excluding tidal waters. | -
NaturalPool_P | Feature Type | A naturally formed pool of water. | It is usually fed by surface drainage from the surrounding region and/or water arising from an underground source (for example: a spring or a resurgence).
NaturalPool_S | Feature Type | A naturally formed pool of water. | It is usually fed by surface drainage from the surrounding region and/or water arising from an underground source (for example: a spring or a resurgence).
Rapids_C | Feature Type | Portions of a stream with accelerated current where it descends rapidly but without a break in the slope of the bed sufficient to form a waterfall. | The surface is usually broken by boulders and rocks.
Rapids_P | Feature Type | Portions of a stream with accelerated current where it descends rapidly but without a break in the slope of the bed sufficient to form a waterfall. | The surface is usually broken by boulders and rocks.
Rapids_S | Feature Type | Portions of a stream with accelerated current where it descends rapidly but without a break in the slope of the bed sufficient to form a waterfall. | The surface is usually broken by boulders and rocks.
RiceField_S | Feature Type | A tract that is periodically covered with water and is used for growing rice. | -
River_C | Feature Type | A natural flowing watercourse. | -
River_S | Feature Type | A natural flowing watercourse. | -
Thalweg_C | Feature Type | An imaginary line connecting the points of lowest bed elevation in a watercourse. | It usually marks the line of maximum flow in the watercourse.
Thalweg_S | Feature Type | An imaginary line connecting the points of lowest bed elevation in a watercourse. | It usually marks the line of maximum flow in the watercourse.
VanishingPoint_P | Feature Type | The location at which a watercourse disappears into the terrain. | -
WaterWell_C | Feature Type | A shaft sunk into the ground to reach and tap a supply of water intended for uses other than power generation, heating or the extraction of minerals. | May be, for example, drilled to tap deep underground reservoirs or dug to reach a shallow water table. Dug wells are typically circular, lined with masonry, have a stone border and a structure built above then for lowering and raising a bucket.

Dug wells are typically circular, lined with masonry, have a stone border and a structure built above then for lowering and raising a bucket.
Waterfall_C | Feature Type | A vertically descending part of a watercourse where it falls from a height (for example: over a rock or a precipice). | In place names, commonly shortened to 'fall' or 'falls', for example, 'Niagara Falls'.
Waterfall_P | Feature Type | A vertically descending part of a watercourse where it falls from a height (for example: over a rock or a precipice). | In place names, commonly shortened to 'fall' or 'falls', for example, 'Niagara Falls'.
