Effect of natural land covers on runoff and soil loss at the hill slope scale
Erosion plots were selected for characterizing the effects of main natural factors on runoff and soil loss in a semi-arid region. These erosion plots with an area of 40 m2 are located in the Kakhk experimental watershed in Gonabad County of Khorasan-e Razave Province in the north-eastern Iran. Data acquired from 2008 to 2015 include slope, aspect, soil texture and land covers (canopy...

متن کاملWatershed conservation prioritization using geomorphometric and land use-land cover parameters
Geomorphometric features and land use/land cover are essential in the context of watershed prioritization for resources conservation and protection. Watersheds in tropical regions like the Philippines are under threat of degradation due to the combined effects of uncontrolled agricultural activities in the uplands and frequently increasing erosive precipitations brought about by climate change....
متن کاملInvestigation on anthropogenic and natural share of heavy metals in surface sediments of Shadegan wetland
Accumulation of trace metals in sediment can cause severe ecological impacts. The present study determines the elemental concentrations and chemical partitioning of heavy metals in surface sediment of Shadegan wetland. Shadegan wetland is one of the most important wetlands in southwest of Iran and it is in Ramsar-listed wetlands. For this purpose, 7 sampling stations were selected for sediment ...
متن کاملPolarimetric Coherence for Land Covers Classification
Synthetic Aperture Radar (SAR) data is extensively used in recent decades for Earth surface monitoring. Advantages of SAR are well-known: good resolution, all-weather, day-and-night etc. SAR Interferometry (INSAR) is a well-established technique which has a lot of applications, e.g., topography mapping, change detection, estimation of surface displacements, thematic mapping. Repeat-pass interfe...
