Structure of bubble plumes in linearly stratified environments
Bubble plumes in a linearly stratified ambient fluid are studied. Four well-defined flow regions were observed: an upward-moving bubble core, an inner plume consisting of a mixture of bubbles andExpand
Reductions in air conditioning energy caused by a nearby park
Abstract Field observations were carried out to determine the influence of a park on the urban summer climate in the nearby areas. The possibilities of reduction in air conditioning energy wereExpand
Heat storage of pavement and its effect on the lower atmosphere
Abstract Heat flux at the air/ground interface was observed and analyzed for various pavement materials on summer days. The surface temperature, heat storage and its subsequent emission to theExpand
Pan‐continental invasion of Pseudorasbora parva: towards a better understanding of freshwater fish invasions
The Pseudorasbora parva invasion has provided quantitative data for the development of 1) early warning systems across different spatial scales; 2) rapid eradication programmes prior to natural spread in open systems and 3) sound risk assessments with emphasis on plasticity of life history traits.

The Influence of Structural Complexity on Fish–zooplankton Interactions: A Study Using Artificial Submerged Macrophytes
This study separated the effects of swimming speed variation and of visual impairment, both due to stems, that led to reduced prey–predator encounters and examined how the reduction of the visual field volume may be predicted using a random encounter model. Expand
Building canopy model for the analysis of urban climate
Abstract For the purpose of practical application of CFD for urban climate planning, a building canopy model coupled with CFD was developed, and the effects of building planting were discussed forExpand
Dynamic modeling of the growth of Phragmites australis: model description
A dynamic model was developed to simulate the growth dynamics of a monospecific stand of Phragmites australis in freshwater ecosystems and showed that irrespective of the varying climatic conditions, the percentage of annual fluxes of an event remained almost same. Expand
Seasonal courses of nutrients and heavy metals in water, sediment and above- and below-ground Typha domingensis biomass in Lake Burullus (Egypt): Perspectives for phytoremediation
Abstract The present study was carried out in natural stands of Typha domingensis in Lake Burullus, Egypt, to investigate (1) nutrient dynamics and heavy metals accumulation in its organs, (2) theExpand
Modeling the effects of macrophyte growth and decomposition on the nutrient budget in Shallow Lakes
Abstract A numerical model was developed to illustrate the annual life cycle and the decomposition process of Potamogeton pectinatus L. Growth, decay, and their interactions were consideredExpand
Seasonal fluctuations in live and dead biomass of Phragmites australis as described by a growth and decomposition model: implications of duration of aerobic conditions for litter mineralization and
A model of Phragmites australis growth and decomposition was developed to evaluate the material budget and nutrient cycles of a reed stand in Neusiedlersee, Austria and found that the aerobic decomposition rate increased markedly, especially from spring to autumn. Expand
