Reduction of Waste Water in Erhai Lake Based on MIKE21 Hydrodynamic and Water Quality Model

Reduction of Waste Water in Erhai Lake Based on MIKE21 Hydrodynamic and Water Quality Model

In order to study the ecological water environment in Erhai Lake, different monitoring sections were set to research the change of hydrodynamics and water quality. According to the measured data, MIKE21 Ecolab, the water quality simulation software developed by DHI, is applied to simulate the water quality in Erhai Lake. The hydrodynamics model coupled with water quality is established by MIKE2...

Understanding selenium distribution in Lake Mead using a three-dimensional hydrodynamic based water quality model

Three-dimensional hydrodynamic and water quality model for TMDL development of Lake Fuxian, China.

Lake Fuxian is the largest deep freshwater lake in China. Although its average water quality meets Class I of the China National Water Quality Standard (CNWQS), i.e., GB3838-2002, monitoring data indicate that the water quality approaches the Class II threshold in some areas. Thus it is urgent to reduce the watershed load through the total maximum daily load (TMDL) program. A three-dimensional ...

Water quality assessment of Vasileva Lake based on diatoms influences by tourism, fishing and recreation

Surface waters in recent years are under the great influence of industrial and anthropogenic factors. Vasileva Lake has been impacted by anthropogenic factors. It has been exploited by people for recreation, vacation and fishing, which exposed Vasileva Lake to occurrence of pollution. Purpose of this work was to evaluate the status of water quality in this artificial lake, using algae-diatoms a...

Evaluation of Gorganrood river water quality based on surface water quality indicators in Gonbad Kavous

Background and Objective: Increased untreated wastewater and unsustainable development of agriculture has deteriorated water quality of rivers. The aim of this study was to determine the quality of water in Gorganrud River basin using NSFWQI IRWQISC and Liou Pollution Index and compare them with the global standards. To do this, GIS software.was used Materials and Methods: In this study, 5 sam...
