Potential of high-resolution detection and retrieval of precipitation fields from X-band spaceborne synthetic aperture radar over land
high-resolution detection retrieval precipitation fields X-band spaceborne synthetic
2011/3/15
X-band Synthetic Aperture Radars (X-SARs), able to image the Earth's surface at metric resolution, may provide a unique opportunity to measure rainfall over land with spatial resolution of about few ...

scaling characteristics observed simulated spatial soil moisture fields
2009/10/30
By providing continuous high-resolution simulations of soil moisture fields, distributed hydrologic models could be powerful tools to advance the scientific community's understanding of the space-time...

Assessment of soil moisture fields from imperfect climate models with uncertain satellite observations
Assessment soil moisture fields imperfect climate models uncertain satellite observations
2009/9/11
We demonstrate that global satellite products can be used to evaluate climate model soil moisture predictions but conclusions should be drawn with care. The quality of a limited area climate model (LA...
Hydrological processes and water resources management in a dryland environment II：Surface redistribution of rainfall within fields
Surface redistribution rainfall within fields Soil water movement
2009/5/26
Soil water movement was studied within fields on two different soil types, a red clay soil and a duplex soil of sand over clay, at the Romwe Catchment in southern Zimbabwe. Each study site comprised t...
Clustering of heterogeneous precipitation fields for the assessment and possible improvement of lumped neural network models for streamflow forecasts
rainfall-runoff Clustering
2009/5/13
This work addresses the issue of better considering the heterogeneity of precipitation fields within lumped rainfall-runoff models where only areal mean precipitation is usually used as an input. A me...
Comparison of soil moisture fields estimated by catchment modelling and remote sensing：a case study in South Africa
soil moisture catchment modelling remote sensing
2009/5/4
The paper compares two independent approaches to estimate soil moisture at the regional scale over a 4625 km2 catchment (Liebenbergsvlei, South Africa). The first estimate is derived from a physically...
Identifying erosive periods by using RUSLE factors in mountain fields of the Central Spanish Pyrenees
erosive periods rainfall volume Central Spanish Pyrenees
2009/4/29
The Mediterranean environment is characterized by strong temporal variations in rainfall volume and intensity, soil moisture and vegetation cover along the year. These factors play a key role on soil...
CO2 and H2O Fluxes Ratio in Paddy Fields of Thailand and Japan
H2O Fluxes CO2 flux Paddy Fields
2009/4/13
Measurements of CO2 flux (FCO2) and H2O flux (FH2O) were carried out on paddy fields of Thailand and Japan during the 2004, 2005 and 2006 growing seasons using the Bowen ratio technique. The objective...
The runoff of suspended, substances, nitrogen, and phosphorus by enforced draining during the ploughing season Experiments in paddy fields
enforced draining Lake Biwa nitrogen paddy field phosphorus SS
2009/4/2
The runoff of suspended substances (SS), nitrogen, and phosphorus by enforced draining during the ploughing season was calculated from experiments in two paddy fields. The area of a paddy field was 30...
