computing or determining the amount of maximum flood debit in watershed is one of the main important parts of hydrological research in river improvement. in this regard it is necessary to be distinguished peak of flood flow and its hydrograph for favorable return period. this needs to have long time statistic and leminograph tools in study research area. in this study with the comparison of ava...
Soil erosion can be considered as one of the most important obstacles in the way of sustainable development of agriculture and natural resources. The aim of this study is to estimate erosion and sediment yield of basin using Erosion Potential Method, in Gorganrud basin, north of Iran. The main factors in the EPM (slope average percent, erosion, rock and soil resistance, and land-use) were evalu...
a professional is someone whose work involves performing a certain function with some degree of expertise. but a narrower definition limits the term to apply to people such as teachers and doctors, whose expertise involves not only skill and knowledge but also the exercise of highly sophisticated judgment, and whose accreditation necessitates extensive study, often university-based as well as p...
One of the most important issues in watershed management is to determine priority for implementing managerial activities. According to the management and decision-making for selecting appropriate locations to implement watershed management projects and also, due to the cost and duration of watershed operations, using decision making methods are very useful. In this study, by using fuzzy SAW and...
[1] Spreading in the Adare Basin off north-western Ross Sea (43–26 Ma) and extension in the Victoria Land Basin (VLB, > 36 Ma) are used to constrain the pole of rotation for the Adare Basin, providing a rifting model for the region for the past 45 Ma. The offset from Northern Basin to VLB at about 74 S coincides with the linear Polar-3 magnetic anomaly, inferred to be caused by a major 48 34 Ma...
In a watershed, land use As one of the most effective factors in basin hydrologic response, Can have significant role in the hydrological cycle and water resources. The knowledge of the effects of land use change on basin hydrology responses can help to determine the appropriate strategy to achieve sustainable development of water resources and a management model. The purpose of this study is t...

chapters 1 and 2 establish the basic theory of amenability of topological groups and amenability of banach algebras. also we prove that. if g is a topological group, then r (wluc (g)) (resp. r (luc (g))) if and only if there exists a mean m on wluc (g) (resp. luc (g)) such that for every wluc (g) (resp. every luc (g)) and every element d of a dense subset d od g, m (r)m (f) holds. chapter 3 inv...
The temporal and spatial characteristics of droughts are investigated to provide a framework for sustainable water resources management in a semi-arid region. Using the Palmer Drought Severity Index (PDSI) as an indicator of drought severity, the characteristics of droughts are examined in the Conchos River Basin in Mexico. This basin is important to both the United States and Mexico, because t...
