A theoretical exploration of catchment-scale sediment delivery

A Catchment-Scale Model of Road Erosion and Sediment Delivery

Unsealed roads and tracks are potentially significant sources of diffuse pollutants, particularly sediment. Identifying critical diffuse pollutant sources and their transport potential can greatly improve catchment-scale water quality management. This study describes the application and ongoing development of a road erosion and sediment transport model in the Moruya-Deua and Tuross River catchm...

Sediment delivery to the three gorges: 1. Catchment controls

The paper examines sediment yield and its response to catchment disturbance and environmental variables in the Upper Ž . Yangtze basin, where the attention of environmentalists has been drawn to the Three Gorges Project TGP . Information about the source and conveyance of sediment from the catchment area to the Three Gorges Reservoir has implications for management strategies. Methodologies for...

Sediment delivery processes at basin scale

Abstract Since eroded sediments are produced from different sources distributed throughout a basin, sediment delivery processes at basin scale have to be modelled by a spatially distributed approach. In this paper a new theoretically based relationship is proposed for evaluating the sediment delivery ratio, SDR{, of each morphological unit, i, into which a basin is divided. Then, using the sedi...

Exploration of Risk Factors Threatening the Health of Mother, Fetus, and Infant in Cesarean Delivery: A grounded Theoretical Study

Background and Objectives: Given the great importance of mother and child health in the community, it is important to identify risk factors during cesarean delivery which is considered as one of the most common gynecological surgeries. Therefore, this study aimed to explore risk factors threatening the health of mother, fetus, and infant during cesarean delivery. Materials and Methods: This gr...
