Note on recent Gully Erosion [PDF]

New Zealand Journal of Geology and Geophysics, 1964
Abstract During recent high rainfalls in Canterbury a small mountain stream that had been diverted over a rock-defended terrace eroded a gully 150 yd long, 50 yd wide, and 25 ft deep during a period of a few hours.

Gully cut- and- fill cycles as related to agromanagement : a historical curve number simulation in the Tigray Highlands [PDF]

, 2015
Gully cut-and-fill dynamics are often thought to be driven by climate and/or deforestation related to population pressure. However, in this case-study of nine representative catchments in the Northern Ethiopian Highlands, we find that neither climate ...

Measuring Strategic, Tactical, Complex and Simple Changes to Farm Systems

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Agriculture is under increasing pressure to redesign farm systems. Governments are increasingly seeking to halt or reverse the damaging effects of agriculture on the environment. Adapting to climate change requires reconfiguring farm systems to withstand more variable, and historically more extreme, seasonal conditions and the constant demand ...

Highly Reversible and Safe Zinc‐Metal Anodes Enabled by a Functional and Antibacterial Interfacial Layer

SusMat, EarlyView.
A functional artificial interfacial layer, containing special carbonyl oxygen groups, is spontaneously constructed in situ on Zn anode by an etching method with malic acid and achieves the long‐term stability of aqueous ZIBs. The carbonyl oxygen with high nucleophilicity and strong zincophilicity can inhibit the side reactions, while enhancing ion ...

Gully erosion in semiarid regions

Procedia - Social and Behavioral Sciences, 2011
AbstractGully erosion, as one of the most critical and destructive water-made types of erosion, results in displacement of huge mass of soil, sedimentation, and degradation. By considering importance of the subjects and with regard to the fact that studied region contains large and extensive gully which introduces potential hazard for croplands and ...

Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Reconstructing long-term gully dynamics in Mediterranean agricultural areas [PDF]

Hydrology and Earth System Sciences, 2017
Gully erosion is an important erosive process in Mediterranean basins. However, the long-term dynamics of gully networks and the variations in sediment production in gullies are not well known. Available studies are often conducted only over a few years,

MERGE: modelling erosion resistance for gully erosion – a process-based model of erosion from an idealised linear gully [PDF]

Soil Research, 2020
Gullies are responsible for as much as 40% of the accelerated erosion impacting the Great Barrier Reef lagoon. Consequently, to protect the reef from the impacts of poor water quality associated with eroded sediment, the remediation of gullied landscapes is important.

Quantifying slope-channel coupling in an active gully and fan complex at Tarndale, Waipaoa catchment, New Zealand [PDF]

, 2010
Two RIEGL LMS‐Z420i scanner surveys (November 2007 and November 2008) of the Tarndale Gully complex and its associated fan were used to generate a digital elevation model (DEM) of difference in order to quantify gully‐fan‐channel connectivity.

Who Makes the Far Right? Exploring Membership Application Data of the National Front of Australia

Australian Journal of Politics &History, EarlyView.
This paper addresses a problem for scholars examining the question of who supports far right political parties or movements. Due to the semi‐clandestine or oppositional nature of far right groups, historians, as well as those in adjacent disciplines, have often been unable to gain access to sufficient records or data to conduct analysis of who supports
