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...
متن کاملGully 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 ...
متن کاملThe 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...
متن کاملGreen Facility Location - A Case Study
“Green logistics” is a popular catchword, not only in public and among companies, but also in academia. In this paper we apply the concept of green logistics to the facility location problem: Optimizing the locations of facilities in the general pmedian model. This is based on CO2 emissions generated through transportation rather than traditional cost measures, such as physical transportation c...
متن کاملA Lagrangian Decomposition Algorithm for Robust Green Transportation Location Problem
In this paper, a green transportation location problem is considered with uncertain demand parameter. Increasing robustness influences the number of trucks for sending goods and products, caused consequently, increase the air pollution. In this paper, two green approaches are introduced which demand is the main uncertain parameter in both. These approaches are addressed to provide a trade-off b...
