The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination
This archetypal form of swale is a dug-out, sloped, often grassed or reeded "ditch" or "lull" in the landform. One option involves piling the soil onto a new bank on the still lower slope, in which case a bund or berm is formed, mitigating the natural (and often hardscape-increased ) risks to slopes below and to any linked watercourse from ...
The steep riverine landscape of both the Driftless Area proper and the surrounding Driftless-like region is the result of early glacial advances that forced preglacial rivers that flowed into the Great Lakes southward, causing them to carve a gorge across bedrock cuestas, [1] thereby forming the modern incised upper Mississippi River valley.
Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order ( anisotropy ) within soils.
In a 1994 assessment of soil erosion in the shire of Bacchus Marsh, Spinoso and Rollings used the Universal Soil Loss Equation to confirm identification in 1973 and 1985 by the Land Conservation Council of Victoria of "an appreciable erosion hazard on steep slopes increas[ing] in intensity in the low rainfall areas in the south east.
The gorge is a transitory Mediterranean climate, as it is located between the Central-European and Mediterranean climate zones. The Struma River cuts through the gorge and is a main geological feature. Near the riverbank are sediment soils which transition into shallow alluvial soil with maroon soil on the side. [4]
Part of the Bungonia Gorge and Bungonia slot canyon run through this park and such formations are characteristic of this type of sedimentary and volcanic activity which formed the original geology of the park. Soil in Bungonia is mostly shallow structured organic loams which lie atop of the limestone and basalt plates which form the main ...
In 2007, the state established the Zoar Valley Unique Area, a 1,492-acre (6.04 km 2) area [7] which further protects and preserves the entire state-owned length of the gorge's cliffs and bottomlands, in addition to a 300-foot (91 m) buffer area along the gorge's upper rim and along several larger side creeks, where sufficient state-owned land ...
