Estimating water quality in river basins using linked models and databases
نویسندگان
چکیده
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 formation of a river model calculation scheme and assessment of river flow rates in every segment. The Pärnu River basin was chosen for testing the tool. Comparison with the measured data demonstrated an adequate behaviour of the linked models. Model simulations indicated that the diffused load forms an essential part in the total sea load and plays a significant role in the formation of river water quality.

Abstract Erosion and sedimentation are the most complicated problems in hydrodynamic which are very important in water-related projects of arid and semi-arid basins. For this reason, the presence of suitable methods for good estimation of suspended sediment load of rivers is very valuable. Solving hydrodynamic equations related to these phenomenons and access to a mathematical-conceptual mode...

متن کاملA New Hydrological Method for Estimating the River Bed and Drainage Basin Components of Erosion and Suspended Sediment Fluxes in River Basins
This paper uses the results of river suspended sediment flux (SSF) analysis to propose a new hydrological method for quantitatively estimating the river bed and drainage basin (sheet erosion, rill and gully erosion) components of total erosion intensity in river basins. The suggested method is based on the establishment of the functional power connection between mean monthly water discharges (W...

Nowadays, there are too many models in the world for simulation of hydrological processes, such as the SWAT physically based model. The SWAT model is a continuous and physically based hydrologic model that is the smallest unit in this model is Hydrologic Response Unit, and all hydrological processes are simulated in each of these units. This model can simulate runoff, sedimentation, erosion and...
