Abstract

Estimation of quality and quantity of natural phenomena is very time consuming and expensive. So INTERPOLATION methods are the suitable ways used to estimate in no sampling locations. There are a lot of common estimation methods and it sounds low differences between them. In the other hand, every planning has been done on the basis of these estimations and if estimation is weak it will cause imprecise decision making. This study conducted to compare some INTERPOLATION methods such as (Nearest point, MOVING AVERAGE, Moving Surface, Trend Surface and KRIGING) to estimate some properties of soil surface. After sampling and measuring variables of gravel, sand, silt and organic matter, these variables were interpolated with above INTERPOLATION methods for some part of MEHR WATERSHED. These methods were tested for three categorizes of site sample including 25, 45 and 70. For every category 30 samples that have not entered in INTERPOLATION were used for determining of accuracy assessment of INTERPOLATION methods. Finally, for every varjable error mean and mean square error indices calculated by actual and estimated data were used for estimate of accuracy and precision of prediction. The results of this research showed that Nearest Point for low sample data and Mean Average (Inverse Distance) for high sample data have more precision. For variables with medium sample, Moving Surface method (Linear Decrease) in comparison of to other methods is nearly more precious that it needs more research in this case.
