A Nitrate-N Leaching Index (NLI) is calculated and the results indicate that nitrogen loss in the study area occurs through both leaching and surface runoff. A non-linear regression model of trapping efficiency was combined with a first order decay model to examine the impact of soil...

This paper compares the performance of a wide range of approaches to testing the martingale difference hypothesis in economic and financial time series. An extensive Monte Carlo experiment is conducted to evaluate and compare the alternative tests under a martingale difference null hypothesis,...

The plausible association between climate change and the variability of water resources in the Tarim River basin, west China is investigated in this study. The long-term trend of the hydrological time series including temperature, precipitation, and streamflow are detected by using both...
