Temporal and Spatial Variation Characteristics of Hydrodynamic Forces in Urban Shallow Lakes

Hydrodynamic Control of Plankton Spatial and Temporal Heterogeneity in Subtropical Shallow Lakes

Hydrodynamic forces and surface topography: Centimeter-scale spatial variation in wave forces

We measured the variability in hydrodynamic forces among locations separated by only centimeters along three horizontal transects on a steep rocky shore. Our results extend previous work showing that wave forces have the characteristics of 1/f-noise, in which variability in wave forces decreases exponentially with decreasing scales of measurement. Furthermore, our results suggest that protectio...

Measuring spatial - temporal of Yazd urban form using spatial metrics

Abstract Urban form can be affected by diverse factors in different times. Socio- economic, political and physical factors are among the main contributors. So, one of the most important challenges of urban planners is measuring and identifying urban development pattern in order to direct and strengthen it to sustainable pattern and right direction. The case study of the present paper is the ...

Spatial and Temporal Characteristics of Road Networks and Urban Expansion

Urban expansion has become a widespread trend in developing countries. Road networks are an extremely important factor driving the expansion of urban land and require further study. To investigate the relationship between road networks and urban expansion, we selected Beijing, New York, London, and Chicago as study areas. First, we obtained urban land use vector data through image interpretatio...

Temporal and spatial variation of the phytoplankton community in the Chahnime Reservoirs-Sistan

This study investigated seasonal changes in density and diversity of phytoplankton, chlorophyll a content, and some environmental characteristics in the Sistan region during 2014. Totally, we detected 28 genera that belonged to five groups of Chlorophyta (12 genera), Bacilloriophyta (7 genera), Cyanophyta (5 genera), Dinophyta (3 genera), and Euglenophyta (1 genus). We observed that Chlorophyta...
