The choice of sampling methods is a crucial step in every field survey in herpetology. In countries where time and financial support are limited, the choice of the methods is critical. The methods used to sample snakes often lack objective criteria, and the traditional methods have apparently been more important when making the choice. Consequently researches using not-standardized methods are ...
Since vegetation is closely related to a variety of hydrological factors, the condition during drought greatly affected by moisture supply or demand from atmosphere. However, since feedback between and climate in event very complex, it necessary construct joint probability distribution that can describe investigate interrelationships them. In other words, required understand interaction terms p...
This study assesses the contribution of LIDAR altimetry, multi-return and intensity information, and aerial photos to coastal wetland investigation. Aerial photos in this area work as reference data to assess the accuracy of the experiment. The performance of Lidar data resources was tested alone with the adaptive TIN algorithms to separate ground points. Multi-return information was employed t...
Polar areas are among the regions where climate change occurs faster than on most of other Earth. To study effects vegetation, there is a need for knowledge its current status and properties. Both classic field observation methods remote sensing based manned aircraft or satellite image analysis have limitations. These include high logistic operation costs, limited research areas, safety risks, ...
Although groundwater resources have long been selected as a safe choice for resolving human water requirements, overexploitation of them, especially at Ardabil plain, has promoted a decrease in the quality and quantity of these resources. One of the significant solutions is to identification of the groundwater potential zones and exploitation of them according to their potentials. The aim of th...
