Digital soil mapping using remote sensing indices, terrain attributes, and vegetation features in the rangelands of northeastern Iran
and spectral indices as auxiliary variables in digital soil mapping models to predict soil properties. A region with an area of 1225 ha located in Bajgiran rangelands, Khorasan Razavi province, northeastern Iran, was chosen. A total of 137 sampling sites, each...
Long term effects of deforestation on soil attributes: case study, Northern Iran
The objective of this study was to investigate the effects of land use change on soil properties in six different sites of Guilan province, northern Iran. The study sites were deforested approximately 40 years ago and changed to tea farms. Soil...
Evaluation of the effect of wastewater contamination on the geotechnical and electrical resistivity properties of a silty clay
Wastewater contamination of fine-grain soils in urban aquifers leads to considerable changes in chemical, physical, and strength properties of this type of soil. This phenomenon is important because the contamination of ...
Vegetation Cover Assessment Based on Soil Properties in Arid and Semi-arid Areas using Landsat Images: A Case Study in Neyshaboor Area
Remote sensing is generally accepted as a powerful technique for land surface studies in arid and semi-arid regions. This technique is also very useful for other environmental studies such as shallow and undeveloped soil properties. In this research...
Virtual Soil Tests for Determination of Particle Properties for Use in DEM Models from Measurable Bulk Properties
Using satellite data for soil cation exchange capacity studies
This study was planned to examine the use of LandSat ETM+ images to develop a model for monitoring spatial variability of soil cation exchange capacity in a semi-arid area of Neyshaboor. 300 field data were collected from ...
Investigation of the Relationships between Rainfall Erosion Processes, Slope and Antecedent Water Content in Semi-Arid Soils
بررسی ارتباط فرآیندهای فرسایشبارانی با درصد شیب و محتوای رطوبتی پیشین در خاکهای منطقه نیمهخشک
فرسایش بارانی نقشی مهم در تخریب خاک سطحی به ویژه در مناطق خشک و نیمهخشک ایفاء میکند. فرسایش ناشی از قطرات باران عامل عمده تخریب خاک مانند تراکم و مقاومت خاک و هدررفت خاک سطحی است. این پژوهش بهمنظور ارزیابی اثرات فرسایش ...
