Regulations increasingly require monitoring to detect changes caused by land management activities. Successful monitoring requires that objectives be clearly stated. Once objectives are clearly identified, it is important to map out all of the components and links that might affect the issues of concern. For each issue and each component that affects that issue, there are appropriate spatial an...

We study the morphology of watersheds in two and three dimensional systems subjected to different degrees of spatial correlations. The response of these objects to small, local perturbations is also investigated with extensive numerical simulations. We find the fractal dimension of the watersheds to generally decrease with the Hurst exponent, which quantifies the degree of spatial correlations....

This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. These images are freely avail...

Climate change and its impact on surface runoff in the upper Blue Nile basin sub-basins have been widely studied future climate projections. However, extreme flow events of rivers is barely investigated discretely. In this paper, temperature rainfall under Representative Concentration Pathway (RCP) highest emission scenario (RCP 8.5) high low simulated by Soil Water Assessment Tool (SWAT 2012) ...

planning of watersheds is indispensable in terms of sustainable development and landscape management. therefore, watershed prioritization and morphometric characterization are important to identify hydrological behavior of the basin for conducting management strategies. in this study, geospatial-statistical approach was used for identifying critical and priority sub-watersheds in the golestan w...
