On 4 December , Ms. Professor Arthur Mynett and Prof. Ann van Griensven were her promotors. At the interface between terrestrial and aquatic ecosystems, the riparian zone plays an important role in nitrogen removal, despite the minor proportion of the land area that it covers.
Modelling herbicide movement from farm to catchment using the swat model
Estimating water balance of Tegona watershed in southeastern Ethiopia, using SWAT model
For model application, the watershed area was divided into 11 sub-watersheds. Available hydrological data i. The model was calibrated at Belkheri gauging site both on daily and monthly basis time scale. Nash and Sutcliffe Efficiency NSE was taken as the main objective function during calibration and validation.

Hydrology Research 1 June ; 50 3 : — Results indicate that streamflow simulation can be effectively improved by downscaling the precipitation datasets. The sensitivities of model parameters vary significantly with respect to different precipitation datasets and sub-basins.
Rattray, Danny James Modelling herbicide movement from farm to catchment using the swat model. While there are many land uses in these areas that contribute to the resultant water quality, of particular concern for the grains farming industry is the widespread detection in rivers of chemicals used by their industry, namely atrazine and metolachlor. A comparison of Hodgson Creek catchment South East Queensland, Australia herbicide data with national water quality guidelines shows that trigger values are frequently exceeded. That water quality trigger values are exceeded is expected for a highly modified catchment such as Hodgson Creek, and the Australian New Zealand Environment and Conservation Council ANZECC guidelines make provision that in such catchments, locally derived targets should be set. Natural resource managers therefore require skills in linking planned management with their ability to set or meet targets.
