soil moisture is one of the critical parameters in climatic, ecological and hydrological modeling and vegetation growth. soil moisture is important for environmental studies but due to ground-based point measurement of soil moisture is expensive and impractical for watershed measurement, this parameter is not be used widely to simulate and predict models. overall and uniform view on different p...
The water yield produced at the outlet of a sub-basin is combination multiple interacting land uses. In majority previous research, while accounting for effect use and cover (LULC) on yield, hydrologic components watershed have been attributed to dominant class within that sub-basin. We adopted an approach investigate interaction LULC (WYLD) using Johnson–Neyman (JN) method. soil assessment too...

We conducted a 5-year study on the impact of nutrients, depending on stream and season. grazing on stream-channel bare ground and erosion, and a © CSA 3-year study of cattle-trail erosion on intermittent stream channels draining grazed oak (Quercus)-woodland 450. Correlations of stocking with the cryptogamic soil watersheds. These studies were conducted on the San crust of a semi-arid rangeland...
The context for watershed analysis Lands to be analyzed Prioritization of watersheds for analysis Relation of the interagency approach to other watershed analysis methods The concept of interagency watershed analysis Goals of watershed analysis Watersheds as analysis units The issue focus Time required for a watershed analysis Consistency and standardization Interagency participation Federal wa...
As the largest service industry in the world, tourism plays a special role in sustainable development. Geomorphic tourism is known to be a segment of this industry with lower environmental impact and underlying causes that explain lower demand; therefore, it is essential to study, identify, assess, plan, and manage natural tourist attractions. As such, the present study assesses the ability of ...

Interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. To protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. As main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. Ecologically, functional parameters such as stab...
