Temporal and spatial distribution of water components in watersheds, estimation of water quality, and uncertaintiesassociated with these estimations are important issues in freshwater studies. In this study, Soil and Water AssessmentTool (SWAT) model was used to estimate components of freshwater availability: blue water (surface runoff plus deepaquifer recharge), green water flow (actual evapot...
Investigating of rainfall behavior in the spatial-temporal dimension and determining the tolerance thresholds of different geographical areas with respect to vegetation, animal life and human activities, is essential for any decision in the environment. Therefore, precipitation data of 27 stations were received from the Meteorological Organization during the 60-year period and After the data we...
Abstract The extention of Snow cover and its spatial and temporal changes considered as a basic parameter in climatic and hydrologic studies. Data from satellite images due to the low cost and the large extention of cover are, effectively help the identifying of the snowy basins. Since the satellites are able to imaging a surface at different times, this will allow snow survey studies to inves...
the objective of this study was to determine the effects of different heel heights on selected gait parameters in a sample of young nigerian females. a purposive sample of eighty apparently healthy undergraduates of nnamdi azikiwe university, nnewi campus participated in the study. their mean age, height, and weight were 21.98± 1.83 years, 1.65±0.06 meters, 59.50±9.34 kilograms respectively. an...
Background: The aim of the study was to assess the effect of an 8-week balance exercise program for enhancement of gait function on temporal and spatial parameters of school aged children with intellectual disabilities. Method: Forty young people with intellectual disabilities were assigned either to the balance exercise program for enhancement of gait function group (BG group, n=19) or the ...
introduction atmosphere health is an important environmental issue and air pollution is not a local problem in a given area of the world. particles produced by either humans or the nature enter the atmosphere and return the earth’s surface at local, regional, or global scales after physico-chemical interactions. according to the reports by who, each year 2.4 million people lose their lives worl...
Multi site modeling of rainfall is one of the most important issues in environmental sciences especially in watershed management. For this purpose, different statistical models have been developed which involve spatial approaches in simulation and modeling of daily rainfall values. The hidden Markov is one of the multi-site daily rainfall models which in addition to simulation of daily rainfall...
Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...
