MODELING THE EFFECT OF SOIL, VEGETATION TYPE AND DENSITY ON SOIL MOISTURE AND SURFACE ENERGY FLUX
Soil moisture SURFACE ENERGY FLUX atmospheric dynamics
2009/10/12
Soil moisture plays a crucial role in hydrological modeling and land-atmosphere energy balance by controlling the amount of evaporation and thermal heat exchange between the land surface and overlying...
Uncertainty of solute flux estimation in ungauged small streams：potential implications for input-output nutrient mass balances at stream reach scale
nutrient retention hydrological conditions
2009/5/18
Input-output mass balances within stream reaches provide in situ estimates of stream nutrient retention/release under a wide spectrum of hydrological conditions. Providing good estimates of the mass b...
The impact of broadleaved woodland on water resources in lowland UK：II. Evaporation estimates from sensible heat flux measurements over beech woodland and grass on chalk sites in Hampshire
broadleaved woodland heat flux water resources chalk sites
2009/5/18
The impact on recharge to the Chalk aquifer of substitution of broadleaved woodland for pasture is a matter of concern in the UK. Hence, measurements of energy balance components were made above beech...
Water discharge and sediment flux changes over the past decades in the Lower Mekong River：possible impacts of the Chinese dams
suspended sediment concentration low water levels Lower Mekong River
2009/5/13
The Lower Mekong River has witnessed extremely low water levels over the past few years. There is speculation that the changes are a consequence of the construction and operation of the Chinese casca...
Metal contamination budget at the river basin scale：an original Flux-Flow Analysis (F2A) for the Seine River
Metal contamination river basin scale original Flux-Flow Analysis
2009/5/13
Material flow analysis and environmental contamination analysis are merged into a Flux-Flow analysis (F2A) as illustrated for the metal circulation in the Seine River catchment. F2A combines about 30 ...
Fluvial organic carbon flux from an eroding peatland catchment, southern Pennines, UK
dissolved organic carbon particulate organic carbon organic carbon
2009/4/29
This study investigates for the first time the relative importance of dissolved organic carbon (DOC) and particulate organic carbon (POC) in the fluvial carbon flux from an actively eroding peatland c...
Assessing environmental impacts on stream water quality: the use of cumulative flux and cumulative flux difference approaches to deforestation of the Hafren Forest, mid-Wales
Plynlimon stream Hore acid neutralisation capacity calcium
2009/3/17
A method for examining the impacts of disturbance on stream water quality based on paired catchment “control‿ and “response‿ water quality time series is described in relation to diagrams ...
Effects of human activities on the Yangtze River suspended sediment flux into the estuary in the last century
riverine sediment flux human activities
2009/3/11
The surface erosion area in the Yangtze River basin increased from 364×103 km2 in the 1950s to 707×103 km2 in 2001 due to a great increase in population. Based on the regression relationship between s...
