Areas sometimes included when referencing the Appalachian region. Northern section is generally not included. Environmental issues in Appalachia, a cultural region in the Eastern United States, include long term and ongoing environmental impact from human activity, and specific incidents of environmental harm such as environmental disasters related to mining.
The lower reaches of the stream are on Leck Kill soil and the rest of the stream is on Hazleton soil. [3] A small hill known as Bunker Hill is located near Cranberry Run. Catawissa Mountain is also in the vicinity of the stream. [7] Very few areas along the stream are prone to flooding. [3] Cranberry Run has a high gradient of 86.8 meters per ...
Wind throw is the toppling of a tree due to the force of the wind, this exposes the root plate and adjacent soil beneath the tree and influences slope stability. Wind throw is a factor when considering one tree on a slope; however, it is of lesser importance when considering general slope stability for a body of trees as the wind forces involved represent a smaller percentage of the potential ...
These contour line furrows create a water break, reducing the formation of rills and gullies during heavy precipitation and allowing more time for the water to settle into the soil. [1] In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally furrows that curve around the land and are level.
The water hardness of the creek's waters 2.90 miles (4.67 km) upstream of its mouth is 24 milligrams per liter (8.7 × 10 −7 lb/cu in). [ 2 ] At 1:00 P.M. on June 26, 1997, the air temperature in the vicinity of Little Catawissa Creek 8.90 miles (14.32 km) upstream of its mouth was 28 °C (82 °F).
SWAT (soil and water assessment tool) is a river basin scale model developed to quantify the impact of land management practices in large, complex watersheds.SWAT is a public domain software enabled model actively supported by the USDA Agricultural Research Service at the Blackland Research & Extension Center in Temple, Texas, USA.

The Soil and Water Conservation Act (RCA) is a 1977 law (P.L. 95-192) that requires the United States Department of Agriculture (USDA) to periodically prepare a national plan for soil and water conservation on private lands based on an inventory and appraisal of existing resource conditions and trends.

The Liquid Limit is the water content at which the soil behavior transitions from a plastic solid to a liquid. The Plastic Limit is the water content at which the soil behavior transitions from that of a plastic solid to a brittle solid. The Shrinkage Limit corresponds to a water content below which the soil will not shrink as it dries.
