Worldwide Testing of the Snowmelt Runoff Model with Applications for Predicting the Effects of Climate Change
Worldwide Testing Snowmelt Runoff Model Effects of Climate Change
2009/10/26
The Snowmelt-Runoff Model (SRM), a simple degree-day model, has been
applied to over 50 basins in 15 countries around the world. Where results have
been reported, the average R' has been 0.84 and th...
The Effect of Climate Change on River Flow and Snow Cover in the NOPEX Area Simulated by a Simple Water Balance Model
Climate Change River Flow Snow Cover NOPEX Area
2009/10/23
Within the next few decades, changes in global temperature and precipitation

Hormozgan province rainfall-runoff flood simulation
2009/10/13
Frequent flood occurrences in the Hormozgan province in the south of Iran cause immense damage to infrastructure, parts of cities and numerous villages, and also claim a number of lives. To study floo...
COUPLED WAVELET-AUTOREGRESSIVE MODEL FOR ANNUAL RAINFALL PREDICTION
autoregressive Wavelet - AR Model ANNUAL RAINFALL
2009/10/12
Because rainfall is one of the most significant parameters in a hydrological model, several stochastic models have been developed to analyze and predict the rainfall process. In recent years, wavelet ...
