Subsequently every watershed along this coast is assigned a number using the Pfafstetter Coding System. This implies that the four largest watersheds are selected and receive numbers 2,4,6, or 8. The watersheds in between the large systems receive numbers 3, 5, and 7. Numbers 1 and 9 are used for the small watersheds on the edges of the strait.
Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary.

Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
The Cibolo Nature Center claims 1,300 acres (5.3 km 2; 2.0 sq mi) of the watershed, to protect the water quality from the hazards of rapid development and population growth. [ 3 ] Several streams serve as distributaries and tributaries of Cibolo Creek, and are included in the watershed.
If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Texas templates]] to the <includeonly> section at the bottom of that page.
Texas has five minor estuaries interspersed among its seven major estuary systems. These are smaller, less complicated estuaries with less significance to the state's hydrology, ecology, and economy. Several of these are simply the lower tidal reaches of particular rivers, without barrier islands or embayments to separate them from the Gulf of ...

In the Permian geologic period, North-Central Texas was a part of the western coastal zone of equatorial Pangea, a super-continental land mass. [1] Nearby uplifts and mountainous regions, such as the Muenster Arch and Red River Uplift, the Wichita, Arbuckle, and Ouachita mountains developed by the end of the Pennsylvanian, [2] providing elevated topography to the north and east during the Permian.
