Article
Full-text available
Transport of water between the coast and the deeper ocean, across the continental shelf, is an important process for the distribution of biota, nutrients, suspended and dissolved material on the shelf. Presence of denser water on the inner continental shelf results in a cross-shelf density gradient that drives a gravitational circulation with offsh...
Article
Evaporation and cooling during autumn and winter in south-western Australia results in denser water near the coast and a cross-shelf density gradient. These conditions drive a gravitational circulation, with offshore transport of higher density water along the seabed, defined as dense shelf water cascades (DSWCs). A field experiment with data colle...
Article
Full-text available
Along the majority of Australian shallow coastal regions, summer evaporation increases the salinity of shallow waters, and subsequently in autumn/winter, the nearshore waters become cooler due to heat loss. This results in the formation of horizontal density gradients with density increasing toward the coast that generates gravity currents known as...
Conference Paper
Full-text available
High evaporation during the summer and cooling during autumn/winter along the coastal regions of the Australian North-West Shelf (NWS) results in a cross-shelf density gradient. This drives a gravitational circulation with the offshore transport of higher density water along the sea bed, defined as Dense Shelf Water Cascades (DSWC). Ocean glider da...
Article
Full-text available
Transport of inshore waters and suspended material off the continental shelf by Dense Shelf Water Cascades (DSWC) has important ecological and biogeochemical implications in Australian waters. Because of high rates of evaporation, denser saline water along the sea bed occurs in the shallow coastal regions around Australia, setting up horizontal den...

Thesis
Full-text available
Along Australian continental shelves, high evaporation during summer and cooling during winter result in a cross-shelf density gradient that drives gravity currents transporting denser water along the sea bed offshore. This process is defined as Dense Shelf Water Cascade (DSWC). Multi-year transects (192) of ocean glider data from eight contrasting...

In this paper, the fundamental properties of flows in an open channel with a dead zone was studied through the three–dimensional numerical simulation using two types of dead zones: one was rectangular side cavity and another one was the dead zone created at the downstream of channel with width enchroachment (i.e. sudden enlarged zone). A non-linear...

Bangladesh is a disaster prone country, and the effect of climate change magnifies the governing factors of the disasters. In this paper, firstly the temporal changes of pattern of different disasters in Bangladesh are discussed based on their occurrence rate, number of people killed, and exposure to human and economic loss. The paper is mainly con...

In this study the water samples were collected from different depth and width wise locations in Shiromoni and Raligate Point of Bhairab River. Using a dataset up to twelve months long in the Bhairab River, the variability of suspended sediment concentration at different temporal scales (monthly) is analyzed. The water samples were collected in thr...

Urban solid waste management is currently been regarded as one of the most immediate and serious issues for city authorities according to the rapidly growing cities of developing countries. Due to inadequate and often inefficient solid waste management and visible environmental degradation, solid waste has also become an important environmental iss...

Drainage system is important for any urban areas to drain out storm water and used water comes from the human being. An improved drainage system can act on this role perfectly. An area's drainage system is directly related to rainfall intensity of that area. In urban drainage design one of the required steps is to determine the rainfall event. The...

Freshwater species of many taxa are declining due to increased stresses placed on freshwater resources from human populations. Habitat destruction and alteration have been identified as the primary reason for the decline of myriad fish species and other aquatic organisms. For this reason small fish production faces a horrible danger and it also aff...

Three–dimensional numerical simulation is carried out to study the fundamental properties of flows in an open channel with a dead zone. In this paper, the flow field in two types of dead zone have been studied: one is rectangular side cavity and another one is the dead zone created at the downstream of channel with width enchroachment (i.e. sudden...

Bhairab River is one of the tidal rivers in Bangladesh, which is the branch of Gorai River that originated from Ganga River. In the region of Rupsha in Khulna city, its name is Rupsha River. The flow of Bhairab River depends on upstream flows comes from Gorai River which plays an important role on its suspendedsediment concentration. The characteri...

In this paper, firstly the temporal changes of pattern of different disasters in Bangladesh are discussed based on their occurrence rate, number of people killed, and exposure to human and economic loss. The paper is mainly concentrated on temporal variation of floods in Bangladesh. The decadal change in return period and probability of low, moder...

The floodplain encroachment in a river is generally created due to construction of hydraulic structures such as embayment, spur-dykes etc. along the river for flood protection, navigation, bank protection, protection of bridges etc. The obstructed flow field in the downstream of a single spur-dyke or the flow field enclosed by two consecutive groy...

Geographically, Bangladesh is situated at the tip of a funnel through which huge amount of rain water discharged in monsoon to the ocean flushing over the country. Depression on the ocean, cyclones, tides and storm surges can easily affect the country through the unprotected shore.Therefore, Bangladesh is a disaster prone country. Effect of Climate...
