Spatial Variability and Prediction Modeling of Groundwater Arsenic Distributions in the Shallowest Alluvial Aquifers in Bangladesh
Arsenic Bangladesh distribution spatial variability semivariogram prediction models
2015/8/13
Elevated arsenic in groundwater is the greatest environmental problem in Bangladesh. Spatial variability of arsenic in groundwater has been examined by semivariogram analysis that revealed high degree...
Prediction of Ground Water Vulnerability using an Integrated GIS-based neuro-fuzzy techniques
Geographic Information System GIS
2015/8/6
There is a need to develop new modeling techniques that assess ground water vulnerability with less expensive data and which are robust when data are uncertain and incomplete. Incorporation of Geograp...
Prediction of scour depth at culvert outlets using neural networks
Prediction scour depth culvert outlets neural networks
2009/12/4
Scour at culvert outlets is a phenomenon encountered world-wide. Research into the problem has mainly been of an experimental nature, with equations being derived for particular circumstances. These t...
An assessment of Bayesian bias estimator for numerical weather prediction
Bayesian bias estimator numerical weather prediction
2009/11/2
Various statistical methods are used to process operational Numerical Weather Prediction (NWP) products with the aim of reducing forecast errors and they often require sufficiently large training data...
DEVELOPMENT OF A STORM RUN-OFF PREDICTION MODEL WITH SIMULATED TEMPORAL RAINFALL DISTRIBUTION
STORM RUN-OFF PREDICTION MODEL SIMULATED TEMPORAL RAINFALL DISTRIBUTION
2009/10/29
The Yamuna catchment up to Kalanur is studied. The representative
character of limited pluviograph data was determined using the storm
index concept. After establishing a relationship between the li...
Satellite Potentials in Snowcover Monitoring and Runoff Prediction
Satellite Potentials Snowcover Monitoring Runoff Prediction
2009/10/29
Earth resources satellites have provided a means for the timely, efficient, and
accurate monitoring of watershed snowcovered area. Several techniques are
available for analysing the data ranging fro...
Snowmelt Prediction in a Subarctic Drainage Area
Snowmelt Prediction Subarctic Drainage Area
2009/10/28
Three prediction methods were tested against observed melt for their ability
to predict snowmelt in a variety of subarctic environments. Four melt environments
were defined according to vegetation c...

Watershed Bounded Network Model Runoff Prediction Large Basins
2009/10/28
Applicability of a nonlinear version of the watershed bounded network model
(WBNM) for large basins namely Shellbyville (1,246 km2), Columbia (3,129
km2), Centreville (5,304 kmz) and Hurricane Mills...
Estimation of Catchment Rainfall Uncertainty and its Influence on Runoff Prediction
Catchment Rainfall Uncertainty Influence Runoff Prediction
2009/10/27
Interpolation of spatially varying point precipitation depths introduces uncertainties
in the estimated mean areal precipitation (MAP). This paper describes
a geostatistical approach - the Kriging m...
THE PREDICTION OF DAILY OUTFLOW FOR AN UNGAGED MOUNTAINOUS BASIN
DAILY OUTFLOW rainfall period Generalized Flood Pattern Method
2009/10/19
To evaluate the daily outflow from a 212-km2 basin in a mountainous part of the downstream Amur river, which has no rain gages, a modeling approach is needed. The average basin rainfall during a rainf...
RETURN PERIOD ANALYSIS AS A TOOL FOR URBAN FLOOD PREDICTION IN THE NIGER DELTA: A CASE STUDY OF PORT HARCOURT CITY, NIGERIA
return period analysis urban areas flood prediction
2009/10/12
The study examined return period analysis as a tool for flood prediction in urban areas. This technique enables us to know when an event is expected to occur, be equaled, or be exceeded. When floods o...
