The MODFLOW Lake Package is integrated into the FREEWAT GIS environment in order to simulate surface water - groundwater interaction using state of the art techniques for numerical simulations, thus allowing the improved consideration of surface water bodies for water resources management. Surface water bodies, both stationary and flowing, can strongly affect groundwater elevations and flow patterns which in turn may affect the qualitative and quantitative state of groundwater resources. With the advancement of numerical simulation techniques and increased model complexity, FREEWAT facilitates the usage of the lake package through existing QGIS tools to edit model layer geometry as well as an intuitive and simple user interface for the specification of constant and time variable lake properties as defined through MODFLOW.

Analysis of the Russian legislation novels aimed at implementation of norms of impact upon environment at the best available techniques level applied to surface water bodies has been presented. It is noted that acting regulations do not completely secure realization of the combined approach to water resources management. In particular, there are no mechanisms to create incentives for further reduction of pollutants discharge to water bodies in case when the best available techniques do not secure attainment of water quality norms or the water body status objectives, when surface water bodies water quality norms accounting their natural and anthropogenic features stipulated by the acting Russian legislation are not yet developed. Proposals on accounting of objectives concerning the surface water body status in the process of regulating impacts upon it on the basis of technological norms and norms of permissible discharge have been made: to calculate surface water bodies water quality objective with taking into account natural and unavoidable anthropogenic factors according the proposed algorithm; when calculating norms of permissible impact to use objectives instead of water quality norms till up to development and approval of the latter (in accordance with the standing legislation); when delivering integrated environmental permissions it is necessary to take into account the norms of permissible impact but not only to observe the technological norms. The recommended procedure of obtaining an integrated environmental permission and setting of provisionally permitted discharge volume for water users discharging waste water to surface water bodies has been described. Proposals on elaboration of the legislative basis have been made.

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.

The Observation Analysis Tool was developed for the FREEWAT GIS environment in order to integrate the data offered by state-of-the-art monitoring systems directly into numerical simulations for water resources management. 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. OAT enables time-series visualisation, pre-processing of data for model development, and post-processing of model results. The tool contains an expandable Python library of processes, incorporating a participatory approach to development. As well as processing MODFLOW results, OAT can act as a pre-processor for calibration observations, and will be expanded to incorporate its processing capabilities directly into the calibration process.
