“…The instream retention is lower -11 and 14%, respectively (Vassiljev and Stålnacke 2005). The study made by Trepel and Palmeri (2002) in Germany shows that nitrogen removal efficiency in surface flow wetlands varies between 22 and 77%.…”

The assessment of the type of human activity in a basin area that may cause an impact on the status of a water body is needed for successful implementation of the EU Water Framework Directive. Lack of necessary information often makes it difficult to perform the task. Therefore, the statistical MESAW model based on export coefficients approach has been used in this study for evaluation of the impact of different sources of nutrients and organic matter on the water quality in the Merkys River in southern Lithuania. The model was tested on the basis of data from 5 water quality monitoring sites with corresponding subbasin data on land use, point sources and atmospheric deposition. Nonlinear regression was used for simultaneous estimation of the export coefficients and retention. The results revealed that the impact of anthropogenic sources accounted for 73% of COD, 56% of BOD, 90% of N tot and 78% of P tot loads measured in the Merkys River. Forest and wetlands contribute from 9.5 to 44% to the corresponding load. The retention in the Merkys River, Basin was found to be high for nitrogen and phosphorus and low for organic matter.

“…The decay rate value for the channels in this watershed was assumed to be similar to those of Florida canals because of similarity in gradient and humid coastal location. Higher values of 0.1 day −1 for natural processes (Heatwole et al, 1987) and 0.12 for a surface flow wetland (Trepel and Palmeri, 2002) have been suggested. The value used herein also falls within the in−stream loss rate range of total N recently compiled by Alexander et al (2000) for streams of Chesapeake Bay.…”

“…It is recognized that this method of quantifying in−stream changes is approximate, but it is easy to apply and has been used successfully in those studies. The relationship for exponential decay of concentration was assumed to be equally valid for nutrient load, which is a product of the concentration and flow rate, as was shown by Trepel and Palmeri (2002). Therefore, the nutrient load delivered from field i to the watershed outlet (L i ) is defined as:…”

“…This practice has received considerable attention as an effective alternative for reducing sediment and nitrate loads from upland agricultural fields to downstream water bodies (Crumpton et al, 2006). However, the efficiency of wetlands in peak flow reduction and in trapping sediments and nitrate depends on their physical characteristics and location within the watershed (Tanner and Kadlec, 2013;Trepel and Palmeri, 2002). Similar to riparian vegetative buffers, wetlands promote reduction of surface flow velocity and consequently flow dispersion and deposition of sediment and attached nutrients and pesticides.…”

“…Methods for determination of potential wetland placement in agricultural watersheds have been proposed using different sources of spatial information. Trepel and Palmeri (2002) proposed a methodology for placement of wetland restoration based on a suitability index calculated from a set of eight geospatial layers: soil type, land use, relief features, terrain slope, distance to stream, socio-economic acceptability, elevation, and spatial location of historical wetlands. In their methodology, individual scores for each geospatial layer were calculated based on further discretization of each layer and varying weights assigned to multiple classes within that category.…”
