The main objective of this work is to better quantify lunar surface minerals (agglutinate, clinopyroxene, orthopyroxene, plagioclase, olivine, ilmenite, and volcanic glass), particle sizes and the abu...
Effect of land use-based surface roughness on hydrologic model output
land use-based surface roughness hydrologic model coefficient Manning parameter sensitivity watershed runoff responses
2015/1/8
The Manning’s roughness coefficient (n) is commonly used to represent surface roughness in lumped and distributed hydrologic models. Model parameter sensitivity studies identify runoff response to be ...
Estimating Limiting Nutrient Loadings in an Interacting Surface and Ground Water Basin
sediment Snake River Basin Idaho
2015/1/6
Watershed management requires the determination of both point and non-point sources of pollution within a watershed. The primary non-point source pollutants in a typical watershed are nutrients (mainl...
Hydrology and Water Balance of Devils Lake Basin: Part 2 - Grid-Based Spatial Surface Water Balance Modeling

2015/1/6
In this part of the study, grid-based spatial water balance approach was used to estimate the annual water balance of Devils Lake basin, hydrologically closed lake located in the Red River of the Nort...
Hydrology and Water Balance of Devils Lake Basin: Part 1 - Hydrometeorological Analysis and Lake Surface Area Mapping
Geographic Information System GIS runoff
2015/1/6
The spatial distribution of stocks of water is useful in studying flood, water pollution and water supply problems. Flood prone and closed basin watersheds benefit from spatial water balance studies i...
Mapping surface soil moisture over the Gourma mesoscale site (Mali) by using ENVISAT ASAR data
Mapping surface soil moisture Gourma mesoscale ENVISAT ASAR
2011/3/15
The potentialities of ENVISAT ASAR (Advanced Synthetic Aperture Radar) multi-angle data for mapping surface soil moisture (SSM) in Sahelian rangelands are investigated at medium scale (30 000 km2). Th...
Cross-evaluation of modelled and remotely sensed surface soil moisture with in situ data in southwestern France
surface soil moisture situ data southwestern France
2010/12/22
The SMOSMANIA soil moisture network in Southwestern France is used to evaluate modelled and remotely sensed soil moisture products. The surface soil moisture (SSM) measured in situ at 5 cm permits to ...
Less rain,more water in ponds:a remote sensing study of the dynamics of surface waters from 1950 to present in pastoral Sahel (Gourma region,Mali)
remote sensing study dynamics surface waters pastoral Sahel
2010/3/5
Changes in the flooded area of ponds in the Gourma region from 1950 to present are studied by remote sensing, in the general context of the current multi-decennial Sahel drought. The seasonal and inte...
