Floristic Composition of Plankton in Shitalakhsya River, Narayanganj, Dhaka

Flood Hazard Mapping of Dhaka-narayanganj-demra (dnd) Project Using Geo-informatics Tools

Dhaka-Narayanganj-Demra (DND) Project is one of about 700 water sector projects built by Bangladesh Water Development Board (BWDB) in Bangladesh. It was a successful project from all considerations. But during 1998 flood, there was overtopping and breaching of embankment. At that time BWDB was able to stop much inundation by doing emergency work. Still many people are building their houses and ...

Geological control of floristic composition in Amazonian forests

AIM: Conservation and land-use planning require accurate maps of patterns in species composition and an understanding of the factors that control them. Substantial doubt exists, however, about the existence and determinants of large-area floristic divisions in Amazonia. Here we ask whether Amazonian forests are partitioned into broad-scale floristic units on the basis of geological formations a...

Floristic study on the algae of Siahdarvishan River in Guilan Province, North Iran

In the present study the freshwater algae of Siahdarvishan River were sampled on a montly basis from December 2007 through November 2008. Three sampling stations (Gaght roudkhan , Shahkezr dame and Talab laleh ) were chosen in the river. Some physical and chemical parameters (water temperature , total hardness , nitrate , nitrite, phosphate and pH) of water samples were measured. A to...
