The objective of this paper is to analyse the production and yield fine sediment in a small mountain catchment (10 km2), characterised by patches badlands (25% area) drained intermittent streams. study area located Southern Central Pyrenees. performed at multiple temporal scales further highlight: (i) effect pulses transfer water sediment; (ii) contribution from catchment; (iii) role drainage n...

This paper presents an experimental study on the microstructure and performance of stabilized earth bricks prepared from the Yellow River sediment. The sediment is modified by inorganic cementitious material, polymer bonding agent, and jute fibre. The results show that the sediment is preliminarily consolidated when the mixture ratio of activated sediment/cementitious binder/sand is 65/25/10. C...

Extended abstract 1- Introduction The Soil surface characteristics have significant effects on the erosion process. The wide areas of watershed soil surfaces are covered with considerable amounts of rocks and pebbles. Surface rock fragments, resulting in water connectivity, change during the erosion process. Rock fragments on the soil surface may increase the infiltration and reduce soil loss...

Turbidity and suspended-sediment changes from stream-crossing construction on a forest haul road in West Virginia, USA" (2013). USDA Forest Service / UNL Faculty Publications. Paper 247. A forested headwater watershed in West Virginia was monitored to examine changes to in-stream turbidity following the construction of a 0.92 km (0.57 mi) haul road. Due to the design of the study, most of the s...

[1] Understanding and quantifying the long-term suspended sediment discharge of drainage basins is a key goal of geomorphology, with important implications for the study of water quality, agricultural sustainability, and the evolution of landscapes and sedimentary basins over geologic timescales. Previous studies have highlighted the importance of relief/slope, precipitation, temperature, veget...

Based on a spatially-distributed sediment budget across the Murray Darling Basin, costs of achieving a range of sediment reduction targets were estimated for a number of locations. Four investment prioritization scenarios were tested to identify the most cost-effective strategy to control suspended sediment loads. The impacts of spatial heterogeneity of sediment transport and varying the spatia...

Desulfurivibrio alkaliphilus strain AHT2(T) is a strictly anaerobic sulfidogenic haloalkaliphile isolated from a composite sediment sample of eight hypersaline alkaline lakes in the Wadi al Natrun valley in the Egyptian Libyan Desert. D. alkaliphilus AHT2(T) is Gram-negative and belongs to the family Desulfobulbaceae within the Deltaproteobacteria. Here we report its genome sequence, which cont...

Community composition of the infaunal bivalve fauna of the St. Lucie Estuary and southern Indian River Lagoon, eastern Florida was sampled quarterly for 10 years as part of a long-term benthic monitoring program. A total of 38,514 bivalves of 137 taxa were collected and identified. We utilized this data, along with sediment samples and environmental measurements gathered concurrently, to assess...
