2018-5-1 · A landslide is a movement of rock or debris down a slope along one or more distinct surfaces. Landslides range in speed from 1 m/day to as much as 300 km/hr. Rockfalls Rockfall (free fall of rock) is an extremely rapid process and occurs without warning. Rockfall is typically the result of frost wedging.
Abstract. For over a century, geomorphologists have attempted to unravel information about landscape evolution, and processes that drive it, using river profiles. Many studies have combined new topographic datasets with theoretical …
2021-1-4 · Concavity in the beach between the discharge point and the supernatant pond is common and a function of material segregation and tailings velocity variations as they flow down the beach. See the beach slope section for more information. Multiple outfall deposition (spigots) is the most common method used to fill a surface storage facility.

2021-7-18 · In this study, several artificial neural network (ANN) models were developed with the help of microstructural characteristics to predict uniaxial compressive strength (UCS) and elastic modulus (E) of migmatites. To this end, 51 migmatite samples were prepared and for each sample some microstructural characteristics along with UCS and E were determined. A semi …
Base-level fall at the mouth of a drainage basin can initiate an upstream-propagating wave of incision (e.g., Gardner, 1983).The manner by which incision migrates up a stream channel is an observation fundamental to understanding the process of river base-level evolution, especially in bedrock-dominated channels.
2004-5-10 · concavity from such plots is further complicated by their finding that rock erodibility varies as the square of tensile strength in laboratory experiments (Sklar and Dietrich, 2001), leading to the possibility that some lithologies can lower at rates in excess of even high long-term rock uplift rates (e.g., 1 cm/a). If so, higher short-term ...

2021-10-13 · Rock categorization based on the P-wave velocities is as accurate as the thin section analysis, which suggests that they can be used together to gain a more accurate initial understanding of the rock types before any laboratory testing. The quality of specimen preparation and rock–machine interaction greatly affect the test results.
Advanced Head Drawing. Master artist Steve Huston brings you his highly-anticipated advanced head drawing series. In the 4th installment, he shows you that the rigid and elastic parts of the face and head dictate their ability to move with a given expression. There are key points of the face that are pushed, and others that are pulled.

2002-8-8 · Visual processing has been subjected to a similar analysis (e.g. Marr, 1982). In general, today the dominant approach to human language and visual processing involves a series of specialized modules, whose internal workings are to some extent isolated from the outside. Each level of analysis is very complex indeed.

2018-2-12 · Active margin coastlines are distinguished by rock erosion that acts in two different directions: waves erode the coast horizontally or landwards, a process that creates sea cliffs; and rivers and streams erode the landscape vertically via channel incision. The relative rates of each process exert a dominant control on coastline morphology.
Academia is a platform for academics to share research papers.
Intrinsic concavity index is thus distinguished from the actual concavity index of the river profile which may be influenced by nonuniform uplift [Kirby and Whipple, 2001], nonuniform substrate lithology [Moglen and Bras, 1995], or downstream variations in sediment flux [Sklar and Dietrich, 1998; Slingerland et al., 1998], as discussed below.
2019-12-21 · rock. The main agents responsible for this process are exfoliation, unloading, erosion, freez-ing, and thawing. Chemical weathering causes both reductions in size and chemical alteration of the original parent rock. The main agents responsible for chemical weathering are hydra-tion, carbonation, and oxidation.

The embryo undergoes a process of flexion to accommodate the neural tube (Fig. 1.5a–c), and in so doing reorientates the primitive embryonic tissues and their relationship to each other.

2004-7-20 · [27] The 44 western, low-uplift channels have concavity indices that range between 0.34 and 2.1, with an average of 0.83 ± 0.06, a value well above both the theoretically predicted range (0.3–0.6) and results from field sites experiencing uniform rock type and rock uplift [Snyder et al., 2000; Kirby and Whipple, 2001].

Here we develop a simple theory for the impact of spatially variable rock-uplift rate on the concavity of bedrock river profiles. Application of the analysis to the Siwalik Hills of central Nepal demonstrates that systematic differences in the concavity of channels in this region match the predictions of a stream power incision model and depend ...
