This paper presents the result of our research in testing the applicability and performance of the AGNPS (Agricultural Non-Point Source) model to estimate sediment yield of a small tropical catchment....
The nature of the bed sediment material distribution in the Mosul dam reservoir is studied. A total of 37 bed sediment samples from the reservoir were collected. The laboratory analysis revealed that ...
Rising levels of atmospheric carbon dioxide and the concomitant increased uptake of this by the oceans is resulting in hypercapnia-related reduction of ocean pH. Research focussed on the direct effect...
In view of the requirement of a well-characterized and easily available aquatic sediment reference material, a comprehensive analysis comprising of fifty major, minor and trace elements as well as Sr-...
Sediment oxygen concentration profiles and benthic microbial oxygen consumption rates were investigated during an IODP site survey in the South Pacific Gyre. Primary production, particle fluxes and se...
Coastal hypoxia and sediment biogeochemistry     Coastal hypoxia  sediment biogeochemistry       font style='font-size:12px;'> 2010/1/20
The intensity, duration and frequency of coastal hypoxia (oxygen concentration <63 μM) are increasing due to human alteration of coastal ecosystems and changes in oceanographic conditions due to globa...
The subarctic Tanana River basin, Alaska, is occupied by ca. 5.6% glacierized region and the other discontinuous permafrost region. Time series of discharge, suspended sediment concentration (SSC) and...
The Tuztaşı Au-Ag mineralized system was discovered within the Kazdağ dome using BLEG (bulk leach extractable gold) and 180-µm stream sediment geochemical data collected across th...
The Gildirli Formation is the oldest Neogene rock unit in the Adana Basin and was formed prior to the regionally extensive Early Miocene marine transgression. These coarse clastic red-beds provide imp...
During the first leg of R/V Meteor cruise M44 in February 1999, geoscientific studies in two areas in the Sea of Marmara were carried out. The studies mainly focused on cool fluid and gas (mainly met...
Sediment Concentration in Lakes Where the Natural Sediment Balance Have Been Changed.
Suspended sediment sources in the Upper Severn catchment are quantified using a composite fingerprinting technique combining statistically-verified signatures with a multivariate mixing model. Composi...
A new approach for estimation suspended sediment yield     sediment yield  sediment routine  sediment concentration       font style='font-size:12px;'> 2009/5/26
A semi-distributed conceptual model, HBV-SED, for estimation of total suspended sediment concentration and yield at the outlet of a catchment was developed and tested through a case study. The base of...
In actively eroding landscapes, fluvial abrasion modifies the characteristics of the sediment carried by rivers and consequently has a direct impact on the ability of mountain rivers to erode their be...
Short-term changes in the flux of particulate matter were determined in the central north western Mediterranean Sea (near DYFAMED site) using drifting sediment traps at 200 m depth in the course of th...
