The scope of the journal includes: (a) Water Resources and Waste Management: This topic includes (i) waste and sanitation; (ii) environmental issues; (iii) the hydrological cycle on the Earth; (iv) surface water, groundwater, snow and ice, in all their physical, chemical and biological processes, their interrelationships, and their relationships to geographical factors, atmospheric processes and climate, and Earth processes including erosion and sedimentation; (v) hydrological extremes and their impacts; (vi) measurement, mathematical representation and computational aspects of hydrological processes; (vii) hydrological aspects of the use and management of water resources and their change under the influence of human activity; (viii) water resources systems, including the planning, engineering, management and economic aspects of applied hydrology. (b) Constructions and Environment: Buildings and infrastructure constructions (bridges/footbridges, pipelines etc) are part of every urban area. In recent years there is a growing interest in seeking rationality of construction systems, in balance with environmental adequacy and harmony in an urban area. This involves, among others, adequacy of structural systems (shapes, functionality, rational design etc), use of alternative materials for construction (recycled, environmentally friendly materials etc) and solutions seeking energy efficiency. (c) Urban Design: This topic covers the arrangement, appearance and functionality of towns and cities, and in particular the shaping and uses of urban public space (e.g. streets, plazas, parks and public infrastructure), including also urban planning, landscape architecture, or architecture issues (e.g. thermic and acoustic comfort). (d) Transportation Engineering: This topic covers such area as Traffic & Transport Management, Rail Transport, Air Transport, International Transport, Logistics/Physical Distribution/Supply Chain Management, Management Information Systems & Computer Applications, Motor Transport, Regulation/Law, Transport Policy, and Water Transport.

Its performance, however, is not extensively tested in medium and large watersheds. Here, we applied DWSM to Upper Oneida Creek watershed located in central New York, USA with an area of 311 km² by dividing it into topographically connected 42 overland elements and 21 channel sections. Field-measured water discharge and sediment concentration data during two storm events, one on 9/30/2010 and the other on 6/28/2010, were used to test the performance of DWSM. Model simulation was performed by calibrating the key adjustable parameters in the input file till the best outcomes were achieved. The final results showed that during calibration for the 9/30/2010 event, DWSM successfully predicted the peak water discharge and its arriving time with the errors of 3.3% and 0%, respectively, and peak sediment discharge and its arriving time with the errors of 0.6% and 0.03%, respectively. For the whole event, DWSM under-predicted total water volume and event sediment load by 10.7% and 22.3%, respectively. Sensitivity analysis indicated that DWSM is most sensitive to the curve number adjustment factor, as well as factors representing flow resistance and flow detachment ability. During validation using the 6/28/2010 event, DWSM showed even better performance in predicting not only the peak values, but also event total values. These results showed that DWSM has the potential of successfully predicting event hydrology and sediment transport in the study watershed.

With more than half of the area used for agriculture (e.g., The complex transport processes of suspended sediment dairy farms and cultivated lands) and urbanization, the at the watershed scale may be more efficiently watershed supplies significantly high sediment loads characterized by physically-based watershed models than other sub-watersheds to Oneida Lake and serves as (Borah and Bera, 2004; Singh and Frebert, 2006). the main source of sediment pollution to the Lake. Among various existing watershed models, Dynamic Quantifying sediment load and its variation is essential Watershed Simulation Model (DWSM) is the one of for the design and implementation of sediment-related relatively high efficiency with a relatively simple best management practices (BMP). The middle and model structure that involves a set of overland elements upper sections of the Oneida Creek watershed were and the connected stream segments (Borah, 2011; Borah selected as the study watershed (Fig. 1) to take and Bera, 2004). It uses several mathematical equations advantage of hydrological data available in a gauging to characterize
