Modeling and Understanding the Relationship between Vegetation and Rainfall of a Tropical Watershed using Remote Sensing Data and GIS
NDVI rainfall modelling calibration verification
2015/8/13
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, viz...

Performance high-resolution X-band radar rainfall measurement Netherlands
2010/2/20
This study presents an analysis of 195 rainfall events gathered with the X-band weather radar SOLIDAR and a tipping bucket rain gauge network near Delft, The Netherlands, between May 1993 and April 19...
Rainfall-runoff modelling using adaptive neuro-fuzzy systems
Rainfall-runoff modelling adaptive neuro-fuzzy systems
2009/12/4
Two important applications of rainfall-runoff models are forecasting and simulation. At present, rainfall-runoff models based on artificial intelligence methods are built basically for short-term fore...
Rainfall and runoff forecasting with SSA–SVM approach
Rainfall and runoff forecasting SSA–SVM approach
2009/12/4
Real time operation studies such as reservoir operation, flood forecasting, etc., necessitates good forecasts of the associated hydrologic variable(s). A significant improvement in such forecasting ca...
An adaptive neuro-fuzzy inference system for the post-calibration of weather radar rainfall estimation
adaptive neuro-fuzzy inference system post-calibration weather radar rainfall estimation
2009/12/4
An Adaptive Neuro-Fuzzy Inference System, based on a jack-knife approach, is proposed for the post-calibration of weather radar rainfall estimation exploiting available raingauge observations. The met...
Neural network rainfall-runoff forecasting based on continuous resampling
Neural network rainfall-runoff forecasting continuous resampling
2009/12/4
Most neural network hydrological modelling has used split-sample validation to ensure good out-of-sample generalisation and thus safeguard each potential solution against the danger of overfitting. Ho...
A multiple linear regression GIS module using spatial variables to model orographic rainfall
multiple linear regression GIS module spatial variables orographic rainfall
2009/12/4
This paper aims to document the development of a new GIS-based spatial interpolation module that adopts a multiple linear regression technique. The functionality of the GIS module is illustrated throu...
Chaos in rainfall:variability,temporal scale and zeros
Chaos in rainfall variability temporal scale zeros
2009/12/4
A recent study on rainfall observed at the Leaf River basin reports that the presence of a large number of zeros in the data significantly underestimates the correlation dimension. The present study a...
Comparative rainfall data analysis from two vertically pointing radars,an optical disdrometer,and a rain gauge
rainfall data analysis vertically pointing radars optical disdrometer rain gauge
2009/11/2
The authors present results of a comparative analysis of rainfall data from several ground-based instruments. The instruments include two vertically pointing Doppler radars, S-band and X-band, an opti...
Quantification of tillage,plant cover,and cumulative rainfall effects on soil surface microrelief by statistical,geostatistical and fractal indices
tillage plant cover cumulative rainfall effects soil surface microrelief
2009/11/2
Changes in soil surface microrelief with cumulative rainfall under different tillage systems and crop cover conditions were investigated in southern Brazil. Surface cover was none (fallow) or the crop...
The lysimeter installation described comprises 36 concrete tanks each with
a soil surface of 4 m2.. The installation is useful for plant growth experiments
under natural conditions involving differe...
FILLING IN GAPS IN RAINFALL RECORDS BY SIMULATED DATA
GAPS RAINFALL RECORDS SIMULATED DATA
2009/10/29
The concept of the rainfall coincidence rate is introduced and is used as
a tool lor corrccting the errors in the rainfall rccords which are due to
shifts. A method of simulating missing rainfall da...
