19 The relationship between meroplankton distribution and spatio-temporal variability of coastal 20 mesoscale hydrological structure was investigated in the northern Bay of Biscay, North-East 21 Atlantic. For the three coastal polychaetes studied, i.e., Pectinaria koreni, Owenia fusiformis, 22 Sabellaria alveolata, the highest larval abundances were sampled in low salinity, low density and 23 h...
In the future, the frequency and the intensity of cyanobacteria blooms in urban lakes are expected to increase in response to climate change and expanding urbanization. In order to study the impacts of watershed changes on cyanobacteria dynamics in urban lakes, a modelling approach, in which an ecological lake model is connected to a hydrological watershed model, is proposed. To validate this a...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
In spatial database, geographic information system (GIS) technology and system engineering theory, the hydro-ecological spatial database was built, and the corresponding hydro-ecological spatial database management information system was designed and developed. From aspects of the data organization and classification, the overall structure of the database, database construction processes and da...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
The complex interactions and feedbacks between humans and water are critically important issues but remain poorly understood in the newly proposed discipline of sociohydrology (Sivapalan et al., 2012). An exploratory model with the appropriate level of simplification can be valuable for improving our understanding of the co-evolution and self-organization of socio-hydrological systems driven by...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
