The phrase "abrupt slope" is correct and usable in written English.
It can be used to describe a steep or sudden change in elevation or angle, often in geographical or mathematical contexts.
Example: "The hikers struggled to navigate the abrupt slope of the mountain trail, which made the ascent particularly challenging."
Alternatives: "steep incline" or "sharp gradient".
This was due to an abrupt slope collapse after long-term scouring effects.
The results can be applied in the transport of fluid-solid mixtures and, in the engineering design of ducts with abrupt slope changes.
Generally the slope fluctuates around a mean value but in certain cases (sites with low seasonal effect) abrupt slope changes are derived and the slope becomes strongly unstable.
The Kalman filter is extended for the background noise filtering, the varying slope adaptation and the non-causal extension for an abrupt slope change.
Our results show that a structural discontinuity in the catchment (i.e. abrupt slope decrease at the junction between piedmonts and the alluvial plain from 2 to 10% to < 0.1%) could be compensated by functional continuity during floods.
Laterally confined laboratory experiments show that when dense surge-like particulate flows travel over abrupt slope reductions their deposits may have an asymmetric bell-shaped thickening near the break of slope.
The sonic attributes of those randomized to RAS enhancement resulted in significantly higher peak frequencies, more abrupt slopes of peak frequencies, selected higher peak volume frequencies relative to baseline and lower frequency levels at peak frequencies (Additional file 3).
In the limestone areas the characteristic landscape consists of karst formations (i.e., precipitous slopes, abrupt, protuberant mountains, caverns, and subterranean streams).
Beyond that belt, known as the Mangyshlak Bank, the middle Caspian, 53,250 square miles (137,917 square km) in area, forms an irregular depression with an abrupt western slope and a gentler eastern gradient.
Abrupt changes in slope occur frequently in some marine environments.
Hence, it is capable to model the abrupt changes of slope (the first derivative of displacement) across a crack.
