Relationships between cataclysmic flood-generated landforms and flood hydraulics were investigated along Box Canyon, an 11 km long bedrock gorge of the lower Big Lost River. Geomorphic mapping along Box Canyon indicates that a cataclysmic flood completely inundated the gorge, resulting in large-scale erosional and depositional features on the adjacent basalt upland. Step-backwater hydraulic mod...

Introduction: Most studies of martian erosion have focused on crater statistics, aeolian landforms and deposits, and valley network morphology. Previous workers have noted that the martian crater population is deficient in craters less than ~30 km in diameter, presumably due to erosion [1], and that ancient martian craters were subjected to different erosional processes than craters on airless ...

The roots of riparian vegetation can reduce fluvial streambank erosion by increasing soil resistance to or altering the applied hydrodynamic force flowing water; however, relative importance these mechanisms is unknown. To assess physical and biological effects plant on erosion, laboratory-scale testing was conducted using a mini Jet Erosion Testing (JET) device. Data analysis three treatment g...

Abstract. Modeling glacial landform evolution is more challenging than modeling fluvial evolution. While several numerical models of large-scale erosion are available, there only a few erosion, and their application over long time spans requires high effort. In this paper, simple formulation which similar to the stream-power model presented. The reproduces occurrence overdeepenings, hanging val...

River science and management often require a design or reference discharge. The common (and sometimes unavoidable) use of such discharges may, however, obscure the fact that the magnitude and frequency of critical flows can differ due to various hydrological, geomorphological, and ecological criteria. Threshold stages and discharges were identified for six lower Brazos River, Texas gaging stati...

Vegetation cover is an important factor influencing the occurrence and movement of rainfalltriggered landslides, and changes to vegetation cover often result in modified landslide behaviour. However, it is difficult to relate the occurrence of landslides directly to variations in land use, especially in some European countries. In contrast, New Zealand provides a good opportunity to investigate...

In addition, one of the following statements should be included. Abstract The Piceance Basin, CO is a type locale for unconventional tight-gas sandstone in the Rocky Mountains (Law, 2002). Productive Williams Fork sandstones are extremely heterogeneous fluvial to marginal marine reservoirs that have very low permeability (<0.1 md) that typically require expensive hydraulic fracturing with 10-20...

Stream channel development in forested areas is profoundly influenced by large organic debris (logs , limbs and rootwads greater than 10 cm in diameter) in the channels. In low gradient meandering streams large organic debris enters the channel through bank erosion , mass wasting, blowdown, and collapse of trees due to ice loading. In small streams large organic debris may locally influence cha...

Soil erosion is one of the most challenging environmental issues in world, causing unsustainable soil loss every year. In South Africa, several episodes gully have been documented and clearly linked to presence Quaternary colluvial deposits on Drakensberg Mountain footslopes. The aim this study was identify assess triggering factors upper Mkhomazi River basin KwaZulu-Natal, Africa. We compiled ...
