“…Similar parameters for sensitivity ranking were found in other Mediterranean catchments (Galván et al, 2009;Mateus et al, 2014;Salmoral et al, 2017). As in the present study, they also found that the GW_DELAY parameter is one of the most sensitive during the streamflow calibration process.…”

“…In the case of LCFG, although the values found are lower, it is still considered a "good" class streamflow performance. Similar values of NSE and R 2 were also found in several SWAT hydrological calibration studies in Mediterranean watersheds (Dechmi et al, 2012;Galván et al, 2009;Mateus et al, 2014;Salmoral et al, 2017). For the quality model assessment, the PBIAS is considered good if its value is in the ± 25% range (Abbaspour, 2011).…”

“…A calibration based on a seasonal scheme is needed (Ricci et al, 2018) and differentiated dynamic baseline flow could provide a strategy to follow (Arnold et al, 1995). Although there are some studies that report very low flows in regulated rivers in Europe (Kirkby et al, 2011), or in Spain (Martinez -Capel et al, 2011Salmoral et al, 2017), no discussion about this condition related with PBIAS is provided.…”

Simulation of flow processes in hyper-regulated Mediterranean watersheds is critical when examining general water demand and established ecological flows of River Basin Management Plans. Weather dynamics in the Mediterranean zone in recent decades have been characterised by a natural variation of drought cycles. In addition, exacerbated climate change proves that water fluxes must be estimated with more exhaustive models. The aim of this study is to assess the water balance of the Cega-Eresma-Adaja (CEA) watershed, including a detailed assessment of land uses and management practices to quantify agricultural water demand for the time period 2004-2014. We used the Soil and Water Assessment Tool (SWAT), given that it is a widespread tool that involves complex processes of the water cycle on a basin scale, providing information on water dynamics related to land use as a fundamental characteristic for water balance calculation. The Nash-Sutcliffe coefficient efficiency value, the main index of calibration and validation performance, was 0.86 for the Eresma-Adaja River and 0.67 for the Cega River. This presents a good result considering the large-scale watershed studied. Analysing dry hydrological years, we found that the estimation of ecological flows for sub-arid zones needs to consider the shallow aquifer-river relationship. During spring-summer periods, with very low flow, monitoring the shallow aquifer levels ensures a good ecological status. The study reveals that aspects such as crop rotation, soil management and their associated measures in Mediterranean basins are key factors for water resource management during drought periods. These results are expected to serve stakeholders and river basin authorities in conducting better-integrated water management practices in the watershed.

Long‐term simulations of agricultural watersheds have often been done assuming constant land use over time, but this is not a realistic assumption for many agricultural regions. This paper presents the soil and water assessment tool (SWAT)‐Landuse Update Tool (LUT), a standalone, user‐friendly desktop‐based tool for updating land use in the SWAT model that allows users to process multi‐year land use data. SWAT‐LUT is compatible with several SWAT model interfaces, provides users with several options to easily prepare and incorporate land use changes (LUCs) over a simulation period, and allows users to incorporate past or emerging land use categories. Incorporation of LUCs is expected to provide realistic model parameterization and scenario simulations. SWAT‐LUT is a public domain interface written in Python programming language. Two applications at the Fort Cobb Reservoir Experimental Watershed located in Oklahoma and pertinent results are provided to demonstrate its use. Incorporating LUCs related to implementation of recommended conservation practices over the years reduced discharge, evapotranspiration, sediment, total nitrogen, and total phosphorus loads by 59%, 9%, 68%, 53%, and 88%, respectively. The user’s manual is included in this article as Supporting Information. The SWAT‐LUT executable file and an example SWAT project with three land use rasters and the user’s manual are available at the United States Department of Agriculture‐Agricultural Research Service Grazinglands Research Laboratory website under Software. Editor’s note: This paper is part of the featured series on Optimizing Ogallala Aquifer Water Use to Sustain Food Systems. See the February 2019 issue for the introduction and background to the series.

“…The sustainability of the water resource from a local perspective is already presented in a few literature studies: a particular emphasis is given to the necessity of reaching a sub-basin scale, however, they focus on a single river basin [9,10] or irrigation district [11]. A recent work [12] proposes a comprehensive approach including efficiency and equity of the water use applied to the Latin American and Caribbean area.…”

Abstract:The aim of this study is to monitor the water use over the national territory and evaluate water flows by economic sectors across regional boundaries. The sustainability level is evaluated in terms of water scarcity (the ratio between water consumption and water availability). Publicly-available geo-referenced maps containing the annual average volume of available and consumed water for different economic activities, pollution loads, and land cover are elaborated with geographic information system (GIS) software. Different administrative and geographic boundaries (regional, river basin, and hydrogeological complex) are used to produce a statistical overview of the sustainability level in water use over the Italian territory. Water footprint indicators are set up for the blue and grey components, while the sustainability of the green component is preliminarily evaluated from land use. The effective impact on the water resource is assessed in terms of water scarcity for all the three components. Water availability data refer to annual average computed between 1990 and 2010. Water consumption and land cover refer to reference year 2006. Results are shown as annual averages and they are used to establish a baseline of the national water use that is expected to be particularly relevant for next-coming analyses, including virtual water flows associated to import/export activities and trending reports for future periods.
