Water Quality Protection Studies of Alborz Dam Upstream

درباره پرژوه

In order to achieve adequate information about river and reservoir quality of Alborz Dam in Savadkooh city, 6-stage sampling and testing of parameters physicochemical, pollution and bio-activity in water and sediment were defined by Regional Water Company of Mazandaran province. The study was performed by Asarab Consulting Engineers Co. and the quality status of springs and entering river and reservoir of Alborz Dam, point and non-point sources of pollutants at the catchment area were completely analysed.

Actual services:

• Consultancy services for establishing a qualitative laboratory for purchasing and equipping the laboratory with spectrophotometer, IC, GC, microbial and biological devices
• Technical specifications of water and sediment sampling devices including CTD device, Multimeter, Niskin, grab, Surber, plankton net, Secchi disk and other devices required for monitoring water bodies
• Gathering basic data of hydrological status in the study area including surface and ground water, pollution sources and climate
• Identification of salinity and land formation as a background pollution sources in the basin
• Identification of point and non-point sources of pollution including agricultural, livestock and industrial centers and its impacts on the water quality of the basin
• Water quality modelling using 2-D Ce-Qual-W2 Model
• Sampling and identification of plankton, macrobenthos, fish and fish parasites
• Providing a temporary monitoring network for the basin (reservoir and inlet rivers)
• Sampling and analysis of the pollution parameters in water and sediment including Total Petroleum Hydrocarbons (TPH), detergents, chlorinated pesticides and microbial parameters in the 9 stations in the dam over 6 months and in the rivers over a year
• Reviewing defined development plans in the basin’s upstream including agricultural and livestock centers, and aquaculture, tourism, industrial and urban development plans
• Impact assessment of the development plans on the surface water quality and eventually reservoir dam
• Zoning of pollution concentrations in the upstream of the basin and the reservoir based on the water quality standards
• Measurement of river flow, sampling and analysis of physicochemical and nutrient parameters
• Provision of structural and non-structural solutions for the watershed (long-term solutions) and in the reservoir (mid-term solutions)
• Delineation of quality buffer zone of dam reservoir and its main stream of the river for each land-uses
