Title

THE EFFECT OF LAND USE ON WATER INFILTRATION CHARACTERISTICS IN SOME SOILS OF ARDABIL AND ZANJAN PROVINCE

Pages

Abstract

 Background and Objectives: Study of soil quality indicators are considered as a useful method in the LAND USE management. Changing the LAND USE affect soil hydrological processes such as water infiltration process. Spatial variation of water infiltration in soil plays a very important role in hydrologic processes. Variability of this process is affected by the inherent and non-inherent characters of the lands. In order to prevent land degradation and soil and water pollution, realizing the respective processes and quantifying their relationships is unavoidable.Infiltration process is one of the most important components of the hydrological cycle. Due to high changes in soil moisture, providing a suitable model for the accurate estimation of infiltration is important. The aim of this study is to evaluate the infiltration characteristics due to LAND USE changes and to determine the best water infiltration model.Materials and Methods: Therefore, water infiltration into soil was measured in seven areas of Zanjan province and one area of Ardabil province at three agricultural, horticultural and bare LAND USEs. Measurement of the water infiltration rate in each LAND USE was conducted by DOUBLE RING method with three replications and at times 0.16, 0.33, 0.5, 0.66, 0.83, 1, 2, 3, 4, 5, 7, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 70, 80, 90, 100, 110, 120, 135, 150, 165, 180, 195 and 210 minute. Also KOSTIAKOV, KOSTIAKOV-Lewis, Horton and Soil Conservation Service of America models were used to estimate soil water infiltration rate. In order to choose a suitable model, RMSE (root mean square error) and R2 (determination coefficient) criteria were determined for each model. Cumulative infiltration and FINAL INFILTRATION RATE were determined for each LAND USE.Results: The results showed that in all three users, all models used in this study could estimate cumulative infiltration water in the soil with acceptable accuracy and low RMSE and high R2.This study suggests estimation of infiltration using models and interpretation of them as logical for all areas study. Also the results showed that the estimated cumulative infiltration of the bare LAND USE by Horton model had maximum R2 (0.999). But in cultivated and horticultural LAND USE by KOSTIAKOV-Lewis model maximum R2 (0.997) was achieved. According to results the cumulative infiltration and FINAL INFILTRATION RATE in cultivated and horticultural LAND USE were higher than those of bare lands. This was mainly due to role of plant, causing more disturbance of the soil surface layer, thus infiltration in the cultivated and horticultural LAND USE is higher than bare lands (in which human factors were less effective).Conclusion: Generally the results of this study showed that cumulative infiltration means in cultivated and horticultural LAND USE were higher than those of bare lands. Also estimation of infiltration using models and interpretation of them is suggested to be logical for all study areas and Horton model to the rest of the models with high accuracy.
