Increasing the hydrophobic monomer (FAD) content up to 50 wt% in the copolymer resulted in longer erosion, whereas further increases up to 70wtt% decreased the erosion period.
Thereafter, control works and the diversion of water decreased the erosion rate, which is presently so slow at the American Falls that large blocks of dolomite accumulate at the base of the falls, threatening to turn it into rapids.
In erosion studies, 15 mg kg−1 of alcohol (IMS) extracted EPS polymer (in 5 g kg−1 IMS precipitate, equivalent to approximately 5 g salt kg−1 sediment dry weight) decreased the erosion threshold of cohesive sediments whereas 30 mg kg−1 (in 10 g kg−1 IMS precipitate, approximately 10 g salt kg−1 sediment dry weight) had no effect compared to controls.
Our results demonstrate that organic farming can potentially decrease the soil erosion risk for row crops because it supports weed development in the furrows, but it can also produce higher erosion rates when crop yields are reduced as a consequence, outweighing the protective effect of the weeds.
He brought forward the ecological balance theory of forest in order to keep the local ecological system beneficial to forestry agriculture, farming and animal husbandry, and to decrease the soil erosion caused by flood.
To decrease the risk of erosion in competitive swimmers, the degree of dental hydroxyapatite saturation should be a controlled parameter in pool water.
Thus, the degree of dental hydroxyapatite saturation should be a controlled parameter in pool water to decrease the risk of erosion in competitive swimmers.
Kitchen Creek is now too steep for its present amount of water flow, and over time erosion will decrease the creek's slope and make it less steep.
Tillage operations performed during the sugarcane replanting (~ 5 years) had a short-term positive effect on soil physical quality, although over time it further decreased the resistance to erosion and structural degradation.
