Experimental Setup for Splash Erosion Monitoring—Study of Silty Loam Splash Characteristics [PDF]

, 2020
An experimental laboratory setup was developed and evaluated in order to investigate detachment of soil particles by raindrop splash impact. The soil under investigation was a silty loam Cambisol, which is typical for agricultural fields in Central ...

Dripping Rainfall Simulators for Soil Research—Design Review

Water, 2022
Dripping rainfall simulators are important instruments in soil research. However, a large number of non-standardized simulators have been developed, making it difficult to combine and compare the results of different studies in which they were used. To overcome this problem, it is necessary to become familiar with the design and performances of the ...

Local generalised method of moments: an application to point process-based rainfall models [PDF]

, 2015
Long series of simulated rainfall are required at point locations for a range of applications, including hydrological studies. Clustered point process-based rainfall models have been used for generating such simulations for many decades.

Automated rainfall simulator for variable rainfall on urban green areas [PDF]

Hydrological Processes, 2019
AbstractRainfall simulators can enhance our understanding of the hydrologic processes affecting the total runoff to urban drainage systems. This knowledge can be used to improve urban drainage designs. In this study, a rainfall simulator is developed to simulate rainfall on urban green surfaces.

SimKat: a virtual laboratory to explore the impact of rainfall variability associated with the A2 climate change scenario on the Western Australian wheat-belt [Abstract] [PDF]

, 2009
The wheat-belt of Western Australia is one of the most vulnerable regions to climate change in Australia (DAFWA, 2007). Over the last century, the landscape is Western Australian has changed drastically with almost 20 million hectares of native ...

Restauração da estrutura do solo por sequências culturais implantadas em semeadura direta, e sua relação com a erosão hídrica em distintas condições físicas de superfície Restoration of the soil structure by crop sequences established in no-till, as related to water erosion in distinct surface physical conditions

Revista Brasileira de Ciência do Solo, 2010
A estrutura do solo desempenha papel de destaque no crescimento de plantas e no controle da erosão e, por conseguinte, na produção de alimentos e na conservação do solo e da água. Considerando isso, realizou-se este trabalho com o objetivo de implementar

Were rivers flowing across the Sahara during the last interglacial? Implications for human migration through Africa. [PDF]

, 2013
Human migration north through Africa is contentious. This paper uses a novel palaeohydrological and hydraulic modelling approach to test the hypothesis that under wetter climates c.100,000 years ago major river systems ran north across the Sahara to the ...
