An Improved Spatio-Temporal Kriging Interpolation Algorithm and Its Application in Slope

open access: yesIEEE Access, 2020
Slope stability analysis based on the deformation monitoring data has been commonly used to predict and warn slope disasters. However, due to breakdown of the monitoring equipment or restrictions and interferences of internal and external factors in the ...

Comparison of sensitivity of interpolation methods by rain gauge network density [PDF]

open access: yesعلوم و مهندسی آبیاری
Different interpolation methods, each with their own strengths and weaknesses, are used to temporal and spatial estimation of precipitation. The accuracy of this estimate depends on the density of point data measured at rain gauge stations. In this study,
