This research was initiated with the objective of investigating the potential of constructed wetlands covered by duckweeds and connected to the branches of Bahr Hadous drain on its salinity, and subsequently, its discharge into El-Salam canal. Primarily, literature was reviewed. Data was assembled and analysed. The water quality model QUAL2K was used in this investigation. Moreover, electrical ...

karun river is the largest and most watery river in iran. this river is the longest river which located just inside iran and ahvaz metropolis drinking water supplied from karun river as well (fa.alalam.ir). karun river as the main source of water treatment plants in ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

Human activities in the recent years have considerably increased the rate of water pollution in many regions of the world. In this case study, the main sources of wastewater discharging into the Gargar River were identified. Using river and point source flow rates and water quality parameters measured along the river, the river water quality was simulated using a commonly used, one-dimensional ...

In recent years, water quality degradation associated with rapid socio-economic development in the Taihu Lake Basin, China, has attracted increasing attention from both the public and the Chinese government. The primary sources of pollution in Taihu Lake are its inflow rivers and their tributaries. Effective water environmental management strategies need to be implemented in these rivers to imp...

The optimal Waste Load Allocation (WLA) problem, in general, is a mathematical model incorporating a water quality simulator within the framework of multi objective optimization. The goals are defined as to improve the water quality and minimize the total treatment cost of dischargers. The fraction removal levels of the dischargers are the decision variables. This paper explores the capabilitie...

This paper describes the usage of linked models for assessment of water quality in a river basin. River water quality model QUAL2K and the Wennerblom (Älvsborg) diffused pollution model were simultaneously applied for water quality and land-based pollution estimations. A software tool was developed to control the data flow between these models and databases. This tool provides automatic formati...
