All images were adjusted using radiometric correction, geometric correction, image enhancement and masking. The results indicate the following: (1) NDVI analysis explained the patterns of adjustment to the new base level; (2) LULC classification showed that significant changes occurred during the study period, and five classes were distinguishable as: the southern dry basin (evaporation ponds) by17km2, the surface water bodies (mainly the Dead Sea), decreased by −34km2, exposed area increased by 20 km2, vegetated area increased by 9 km2. The rate of urban changes between 1984, 2003 and 2015 was calculated; it is indicated that the rate of urban growth...

Ordinary kriging (OK), genetic algorithm based on artificial neural network (GA-ANN), adaptive network fuzzy inference system (ANFIS), and conditional simulation (CS) have been used for spatial distribution modeling. A total number of 80 surface sediment samples were collected in the year 2007 in Caspian Sea and Volga Delta in framework of the Caspian Ecosystem Program (CEP) which focuses on contaminants survey. As part of these samples, five countries of Iran (18 samples), Azerbaijan (16 samples), Turkmenistan (21 samples), Kazakhstan (13 samples), and Russia (12 samples). Results indicate that the CS realizations yields interpolation values such that the parsimony principle can not be kept. Simulated maximum and minimum values based on the CS method, is less and more than corresponding observed values, respectively. The OK realization smoothed out spatial variability and extreme measured values between the range of observed minimum and maximum values for all of the contaminants. The GA-ANN model has been capable of simulating the minimum values of contaminants as well. ANFIS, GA-ANN and OK are capable simulate the average values of contaminants, as well, except Cd and Hg. The results of spatial distribution modeling of Cd, Cu, Hg, Pb, and Zn show that the maximum concentrations of these contaminants are distributed in the south of Caspian Sea, near the boundary of Azerbaijan and Iran. In the case of As, maximum concentration is found in the north and south of the study area. Finally, comparison between the four interpolated techniques, GA-ANN model is the best model in keeping the statistical characteristics of the observed data for all contaminants, however ANFIS model is the best model with least simulation errors.

DEM is a computerized representation of the Earth's relief, and is used in many applications such as hydrology, climatology, geomorphology and ecology. There are some important differences in assessing the accuracy of digital elevation models for specific applications. The purpose of this study is to investigate the errors in digital elevation models obtained globally from DEMs 90 m, 30 m ground resolution, and the extracted DEM from a topographic map by digitized contour lines of 1:50,000 scale in a rugged mountainous region and a heterogeneous landscape, using KS (kernel smoothing) interpolation method. For validation purposes, datasets of 250-GCPs (ground control points) distributed over the study area were used to evaluate and compare the accuracy of the two global Dems and the DEM extracted from TM. The main results showed that the 30 m resolution global (DEM) is the most accurate one among the three. According to the validation results, SRTM with maximum (+) and minimum (-) error elevation is-10_9. M, with mean deviation of KS is-0.00238667, and RMS (root-mean-square) error of 0.98, and currently the most accurate model is 30 m DEM of the study area with no significant differences compared with DEM 90 m.

The Zarqa river basin has been affected by water scarcity, frequent drought conditions which lead to the decadence of the discharge level of the Jordan River, which form the base level. The studied area is part of Jordan Rift Valley (JRV), and located 40 km from king Talal dam (KTD), and reach about 4 km in length. The data used for the analysis was the digital elevation model derived from SRTM and historical Air photo and topographic maps from 1963 and 1978. The interpretation was aimed to determine the changes patterns of the channel and valley characteristics that caused by the large reduction of water flow, and the increase of sediment concentration in the bed river. Parameters of analysis that has been taken place in the river properties were grouped into three categories as follows: (1) The Channel length, width, and meandering level. (2) The centerlin...

Based on Topographic Position Index (TPI), and depend upon Shuttle Radar Topography Mission (SRTM) data for preparing digital elevation model (DEM) which is available with 30*30 m ground resolution. By using the TPI, the landforms were classified into both Slope Position index and landform types. Landform categories were generated by combined two TPI grids at different scales (neighborhoods: (a 1km radius and 2km radius). TPI defended as: algorithms of Weiss and Jenness used to measure the topographic slope positions and automated landform classifications. TPI values are depended upon the cell size, type, elevation, and the standard deviation (SD) of TPI. By using TPI, the study area classified into slope position index with 6 classes; Valley, Lower slope, Flat slope, Model Slope, Upper Slope, Ridge, and the Landform categories with 10...

The primary goal was to create a more accurate map to estimate vegetation criteria (above ground biomass AGB), soil organic matter, soil texture, and the hydrothermal coefficient using Landsat 8 satellite imagery. The analysis used Landsat 8 imagery from the 2016 summer season with a resolution of 30 meters, time series MODIS vegetation products (MOD13, MOD15, MOD17) averaged over 16 days from June to August 2000-2016, an SRTM DEM with a resolution of 30 meters, and a field survey of measured biomass and soil data. In total, 6 main factors were classified and quality evaluation criteria were developed for 17 criteria, each with 5 levels. In this research the spatial MCDM (multi-criteria decision-making) method and AHP based GIS were applied. This was developed for each criteria layer's value by multiplying parameters for each factor obtained from the pair comparison matrix by the weight addition, and by the suitable evaluation of several criteria factors affecting cropland. General accuracy was 88%, while PLS and RF regressions were 82.3% and 92.8%, respectively.
