FREEWAT is an ongoing GIS environment to serve as pre- and post-processor for running simulations of surface-/groundwater interaction, with the possibility to activate several features accounting for the different water stresses. This paper reports the capability related to address water resource management problems, by activating management tools available in the MODFLOW-OWHM code. The latter is integrated in FREEWAT, which appears as composite plugin of the well-know QGIS software (QGIS, 2016). Therefore, all the necessary pre- and post-process procedures can be run effectively within QGIS, also in conjunction with the several tools for GIS analysis already included in QGIS. It turns out a simple and intuitive user interface to manage the simulation of complex problem in which the mutual interaction among surface waters, groundwaters and anthropic water demand/supply terms can be handled. The development phase of such tools is already at an advanced stage, while next work will be focused on producing real-world applications to serve as tutorial for interest Users.

Time-series are an important aspect of environmental modelling, and are becoming more available through the requirements of the water framework directive as well as more important with the advancement of numerical simulation techniques and increased model complexity. For this reason, within the H2020 FREEWAT project, which aims at facilitating the adoption of modeling for water resource management, the integration of a tool for time-series analysis and processing has been foreseen. As a result the Observation Analysis Tool was developed to enable time-series visualisation, pre-processing of data for model development, and post-processing of model results. Observation Analysis Tool can act as a pre-processor for calibration observations, and will be expanded to incorporate its processing capabilities directly into the calibration process. The tool consists in an expandable Python library and in an interface integrated in the QGIS FREEWAT plug-in which include a large number of modelling capabilities, hydro-chemical data management tools and calibration capacity. The tool has been extensively used and tested in different european institutions, to collect a number of indications to drive the future development.

Abstract Chemical pollution of water bodies is a complex problem around the globe. When described by the extremes of the range of problem definitions, water bodies can be chemically polluted by a single compound that is emitted from a point source or an incidental spill, or by chronic diffuse emissions from local and upstream land uses. The resulting mixture exposures can vary in space and time, e.g. due to the use of pesticides in the crop growing season. The environmental management objectives are commonly to protect and restore surface waters against human influences. Currently, chemical pollution is globally judged for a selected set of compounds, by judging each of these individually in comparison with protective environmental quality standards. Research has provided a novel assessment paradigm (solution-focused risk assessment) and novel data, measurement methods and models to improve on current practices. Their adoption and application require establishing novel linkages between the diverse problem definitions and the novel approaches. That would assist water quality professionals to select the most effective option or options to protect and restore water quality. The present paper introduces the RiBaTox (River Basin Specific Toxicants assessment and management) web tool. It consists of short descriptions of the novel approaches (made available as Additional file 1) and a decision tree for end-users to select those. The overview of novel approaches collated in RiBaTox is relevant for end-users ranging from local water quality experts up till strategic policy developers. Although RiBaTox was developed in the context of European water quality problems, the methods provided by RiBaTox are relevant for users from (inter)national to local scales. This paper is part of a series of Policy Briefs from the EU-FP7 project SOLUTIONS (http://www.solutions-project.eu), which provide backgrounds on chemical pollution of surface waters and policy practices and proposed improvements.

Optimal site selection of a dam is one of the crucial tasks in water resource management. In this study, a dam suitability stream model (DSSM) is utilized to identify potential sites for constructing multi-purpose dams. In DSSM, each input parameter is weighted using the analytic hierarchy process (AHP), and then weighted overlay analysis is performed in a Geographical Information System (GIS) environment. Compared to the previous studies, this study showed different results based on the crucial parameter that is “stream order”. Two resultant site suitability maps are prepared to differentiate the importance of stream order. Each of the resulting maps visualizes four classes of suitability from highly suitable to least suitable. The proposed sites will store water for a variety of uses at the local and regional level and reduce flood risk, which can be very useful for hydrologists and disaster risk managers.

In this study, GIS technique and remote sensing data have been integrated to createa suitability map for the probable sites of water harvesting in Badrah-Wasit, EasternIraq.Hydrological analysis used to find the potential water-harvesting sites, as well as to improve the water resource management. In this research, five criteria have been used, which is astream order, slope, distance to roads, rainfall and Normalized Difference Vegetation Index. These thematic layerswere evaluated with the multi-criteria analysis method, then combine and process together using weighted overlay method, then assigned suitable weights and integrated into a GIS to generate a suitability map.As a result, the region has been classified into three zones: high suitability zone (2%), moderate suitability zone (27%), and low suitability zone (35%) depending on the specific criteria used for this purpose and have high potential in terms of their suitability for water harvesting.

Virtual reconstruction of an urban historical landscape over a relatively large area requires the reconstruction of historical land surfaces. To solve this problem one needs to obtain a detailed spatial data on the Earth surface elevation for a certain historical period as well as the information about the way it changed over time. The reconstruction can be performed using different software. One of the convenient options is to use geographic information systems (GIS) since this approach assumes work with georeferenced data “by default” thus providing for easier combinations with other reconstruction components. The article describes the creation of digital relief models (DRMs) of the eastern part of Moscow Bely Gorod reflecting the state of the land surface in the 16th, 17th and 18th centuries via GIS software (MAG, SAGA, QGIS). Input data for this research are contours from 1:2000 topographic plans and generalized materials of archaeological sources. Using this basis as well as GIS analysis methods, three gridded DRMs (one for each epoch) have been constructed. These DRMs are suitable for use within the GIS environment and for export to other software.

The Srepok river basin (28,600km2) is located in the Central Highlands of Vietnam. There are many critical issues for soil and water resource management in the basin. Therefore, to make suitable adaptation plans, decision makers need to understand the extent of the potential impact of both climate change and human activity on local soil and water resources. The objective of this chapter was to investigate changes in stream flow, sediment load, and hydrological processes resulting from land use change and climatic variation. Plausible scenarios of land use change developed in a GIS environment based on current conditions, information from the area, and climate change scenarios were built on outputs of GCMs from the SEA-START. These changes were then inputted into SWAT model to project future hydrological variables. Results demonstrated that stream flow was predominant, followed by evapotranspiration. Groundwater was more predominant than surface water. This has been one of the best outstanding advantages in the Srepok watershed.
