REMOTE SENSING DATA ASSIMILATION IN WATER QUALITY NUMERICAL MODELS FOR SIMULATION OF WATER COLUMN TEMPERATURE
data assimilation numerical model water temperature
2015/1/16
Numerical models are important tools for simulating processes within complex natural systems, such as hydrodynamics and water quality processes within a water body. From decision makers’ perspectives,...
A Method for Extracting Stream Channel Flow Paths from LiDAR Point Cloud Data
Streams Channels Delineation
2015/1/9
Traditional methods of delineating stream channel networks use gridded raster elevation data. Direct use of LiDAR point clouds, without first creating a raster or grid, could improve efficiency and ac...

wetlands remote sensing mapping, delineation
2015/1/7
Overarching goal of this paper was to evaluate automated and semi-automated methods of
mapping wetlands using Landsat ETM+ and SRTM data.
Automated methods consisted of: (a) slope derived from SRTM,...
Modeling and Understanding the Relationship between Vegetation and Rainfall of a Tropical Watershed using Remote Sensing Data and GIS
NDVI rainfall modelling calibration verification
2015/1/7
A model is developed to understand the relationship between satellite-derived NDVI and rainfall
data in a large tropical catchment. Two Fourier-based modeling techniques with a seasonal
component, v...
Estimation of aquifer hydraulic characteristics from electrical sounding data: the case of middle Imo River basin aquifers, south- eastern Nigeria
Dar - Zarrouk parameters Resistivity Imo River Basin Nigeria
2015/1/6
We have used the concept of Da - Zarrouk parameters (transverse unit resistance (R) and longitudinal conductance (C)) in porous media to determine aquifer hydraulic characteristics within the middle I...
Performances of Stochastic Approaches in Generating Low Streamflow Data for Drought Analysis
monthly-minimum daily discharge stochastic model
2015/1/5
This study analyzed the monthly-minimum daily discharge data of each month from three gauge stations on Cekerek Stream for forecasting using stochastic approaches. Initially non-parametric test (Mann-...
GIS Integration of Remote Sensing and Electrical Sounding Data for Hydrogeological Exploration
Groundwater GIS Remote Sensing
2014/11/12
Interpretation of hydrogeological data frequently involves assimilating information from many
sites each with a unique geographical location. Interpretation of these data requires that the
spatial l...
