After the Last Gully Washer

Gully Erosion after Wildfire

Predicting runoff and erosion from watersheds burned by wildfires requires an understanding of the spatial structure of both hillslope and channel drainage networks. We investigate the small-scale and large-scale structures of drainage networks using field studies and computer analysis of 30-m digital elevation model. Topologic variables were derived from a composite 30-m DEM, which included 14...

The ELx405TM Washer A Family of Washer to Meet the Diverse Needs of Biological Screening

To address the diversity of microplate washing requirements, BioTek has developed the ELx405TM, a family of microplate washers that provides versatility, as well as dedicated capabilities. The ELx405 Select Microplate Washer uses a patented manifold design which provides independent control of aspirate and dispense tube location and height enabling bubble free fluid dispense and overflow protec...

Gully Formation on Mars and Earth: the Transition from Glacial Activity to Gully Depositional Phases

Introduction: The discovery of gullies on Mars [1,2] resulted in a wide variety of proposed candidate mechanisms for formation but ensuing analyses have shown very strong latitude and orientation dependencies on their distributions [3-6]. These constraints have been interpreted to require: 1) a volatile on or near the surface as a source of liquid water, and 2) insolation and slope orientation ...

The Gully Erosion Effect On the Environment

The paper contains data about the destructive effects of gully erosion on the environment. It provides general information about the gully erosion in several countries around the world including Romania and is considered a case study for a river basin located in the Semenic Mountains (Bârzava drainage area). The case study is based on the following assumptions: the presence of different types o...
