“…Simulating hydrologic and biogeochemical cycles at a watershed scale with a physical process-based model is challenging because numerous processes and linkages govern dynamics of water and nutrients, and uncertainties arise from simplified representation of processes or a lack of climatic stations to represent spatial variability of rainfall in the watershed (Abbaspour et al 2007;Bieger et al 2012). The most extreme flood peaks were underestimated by the calibrated SWAT model (Fig.…”

The impacts of climate change on water and nitrogen cycles in arid central Arizona (USA) were investigated by integrating the Second Generation Coupled Global Climate Model (CGCM2) and a widely used, physical process-based model, Soil and Water Assessment Tool (SWAT). With statistically downscaled daily climate data from the CGCM2 as model input, SWAT predicted increased potential evapotranspiration and decreased surface runoff, lateral flow, soil water, and groundwater recharge, which suggests serious consequences for the water cycle in this desert catchment in the future. Specifically, stream discharge is projected to decrease by 31 % in the 2020s, 47 % in the 2050s, and 56 % in the 2080s compared to the mean discharge for the base period (0.73 m 3 /s). A flowduration analysis reveals that the projected reduction of stream discharge in the future is attributable to significant decreases in mid-range and low-flow conditions; however, flood peaks would show a slight increase in the future. The drier and hotter future also will decrease the rate of nitrogen mineralization in the catchment and ultimately, nitrate export from the stream. Since mean mineralization rate would decrease by 15 % in the 2020s, 28 % in the 2050s, and 35 % in the 2080s compared to the based period (9.3 g N ha −1 d −1 ), the combined impact of reduced catchment mineralization and reduced streamflow would predict declining nitrate export: from today's mean value of 30 kg N/d, to 20, 15 and 12 kg N/d by the 2020s, 2050s, and 2080s, respectively.

“…Flow calibration was focused on monthly simulations using the SWAT Calibration Uncertainty Procedures (SWAT-CUP) version 5.1.6.2. In this paper, we apply the calibration using the Sequential Uncertainty Fitting procedure (SUFI-2) (Abbaspour et al, 2007), based on streamflow data from January 1995 to December 2008, using the data from a gauging station at Vitória de Santo Antão.…”

“…Surface runoff contributes to pointsource pollution, particularly after a storm, as well as diffuse pollution from industries such as agriculture. Models, such as SWAT (soil water assessment tool) developed by Abbaspour et al (2007), can be used to simulate the flow and transport of pollution, as well as physical characteristics such as river discharge and sediment concentration at the watershed scale. These types of tools can increase the understanding of the relationship between land use and runoff (Hundecha and Bárdossy 2004) and enhance initiatives aimed at managing the impacts of different land uses on the watershed.…”

Integrated watershed management: evolution, development and emerging trends

et al. 2016

Watershed management is an ever-evolving practice involving the management of land, water, biota, and other resources in a defined area for ecological, social, and economic purposes. In this paper, we explore the following questions: How has watershed management evolved? What new tools are available and how can they be integrated into sustainable watershed management? To address these questions, we discuss the process of developing integrated watershed management strategies for sustainable management through the incorporation of adaptive management techniques and traditional ecological knowledge. We address the numerous benefits from integration across disciplines and jurisdictional boundaries, as well as the incorporation of technological advancements, such as remote sensing, GIS, big data, and multi-level social-ecological systems analysis, into watershed management strategies. We use three case studies from China, Europe, and Canada to review the success and failure of integrated watershed management in addressing different ecological, social, and economic dilemmas in geographically diverse locations. Although progress has been made in watershed management strategies, there are still numerous issues impeding successful management outcomes; many of which can be remedied through holistic management approaches, incorporation of cutting-edge science and technology, and cross-jurisdictional coordination. We conclude by highlighting that future watershed management will need to account for climate change impacts by employing technological advancements and holistic, cross-disciplinary approaches to ensure watersheds continue to serve their ecological, social, and economic functions. We present three case studies in this paper as a valuable resource for scientists, resource managers, government agencies, and other stakeholders aiming to improve integrated watershed management strategies and more efficiently and successfully achieve ecological and socio-economic management objectives.
