چکیده
One main source of information were cartographic maps of the “Esteros del Iberá” developed by the Military Geographic Institute (IGM, Instituto Geográfico Militar). Nineteen maps in the scale 1:100000 were required to cover the study area. The main information retrieved from the maps were the Level Curves (LC). We decided to use the LC in order to define the limits of the watershed by using a Geographic Information System (GIS). Hence, our first step was to digitalize the LC and use the GIS functions to define the watershed.

Analysis of the dynamic behavior of the car user in the irregular terrain
Many people experience vibration effects on whole-body throughout their lives frequently. Vibrating energy absorbed is exposed all-body caused with vibration hazard in the vertically on body and biodynamic responses from body in speed 2.37 to 5.14 m/s could captivate with car seat on user body, so the vibration energy transferred to a seated people body. In this paper, the human body is modeled...
متن کاملبررسی رابطه بین تولید گندم و خصوصیات پستی و بلندی زمین در منطقه اردل استان چهارمحال و بختیاری
Crop yield, soil properties and erosion are strongly affected by terrain parameters. Therefore, knowledge about the effects of terrain parameters on strategic crops such as wheat production will help us with sustainable management of landscape. This study was conducted in 900ha, of Ardal district, Charmahal and Bakhtiari Province to develop regression models on wheat yield components vs. terrai...
متن کاملAssessment of Terrain and Land Use/Land Cover Changes of Mine Sites using Geospatial Techniques in Plateau State, Nigeria
In this paper, we report a geospatial assessment of the selected mine sites in the Plateau State, Nigeria. The aim of this work is to determine the impact of mining on the terrain as well as the Land Use/Land Cover (LULC) of the host communities. The Shuttle Radar Topographic Mission (SRTM) is used for the terrain mapping. The derived impact of mining on LULC between 1975 and 2014 is determined...

متن کاملA Numerical Investigation on Aerodynamic Coefficients of Solar Troughs Considering Terrain Effects and Vortex Shedding
Recently, increase in the cost of fossil fuels and taking into consideration the environmental effects of exploiting them, caused many researchers and governments to find some ways to make use of renewable energies more cost-effectively. Solar energy is a category of renewable energies which could be harvested via several technologies. One of the most practical methods is using parabolic trough...
متن کاملPresenting a Morphological Based Approach for Filtering The Point Cloud to Extract the Digital Terrain Model
The Digital terrain model is an important geospatial product used as the basis of many practical projects related to geospatial information. Nowadays, a dense point cloud can be generated using the LiDAR data. Actually, the acquired point cloud of the LiDAR, presents a digital surface model that contains ground and non-ground objects. The purpose of this paper is to present a new approach of ex...
