As such, in order to prepare pollution prevention plans and measures or to set-up timely remedial options, especially in the early stages of pollution incidents, simulation tools are of great help for authorities, with specific reference to environmental protection agencies and river basin authorities. In this paper, we present the development and testing of the ORGANICS plugin embedded in QGIS. The plugin is a first attempt to embed surface water solute transport modelling into GIS for the simulation of the concentration of a dissolved substance (for example an organic compound) in surface water bodies including advection dispersion and degradation. This tool is based on the analytical solution of the popular advection/dispersion equation describing the transport of contaminants in surface water. By providing as input data the con...

Climate change impact assessment on Veneto and Friuli plain groundwater. Part I: An integrated modeling approach for hazard scenario construction
Science of the Total Environment, 2012
Climate change impacts on water resources, particularly groundwater, is a highly debated topic wo... more Climate change impacts on water resources, particularly groundwater, is a highly debated topic worldwide, triggering international attention and interest from both researchers and policy makers due to its relevant link with European water policy directives (e.g. 2000/60/EC and 2007/118/EC) and related environmental objectives. The understanding of long-term impacts of climate variability and change is therefore a key challenge in order to address effective protection measures and to implement sustainable management of water resources. This paper presents the modeling approach adopted within the Life+ project TRUST (Tool for Regional-scale assessment of groUndwater Storage improvement in adaptation to climaTe change) in order to provide climate change hazard scenarios for the shallow groundwater of high Veneto and Friuli Plain, Northern Italy. Given the aim to evaluate potential impacts on water quantity and quality (e.g. groundwater level variation, decrease of water availability for irrigation, variations of nitrate infiltration processes), the modeling approach integrated an ensemble of climate, hydrologic and hydrogeologic models running from the global to the regional scale. Global and regional climate models and downscaling techniques were used to make climate simulations for the reference period 1961-1990 and the projection period 2010-2100. The simulation of the recent climate was performed using observed radiative forcings, whereas the projections have been done prescribing the radiative forcings according to the IPCC A1B emission scenario. The climate simulations and the downscaling, then, provided the precipitation, temperatures and evapo-transpiration fields used for the impact analysis. Based on downscaled climate projections, 3 reference scenarios for the period 2071-2100 (i.e. the driest, the wettest and the mild year) were selected and used to run a regional geomorphoclimatic and hydrogeological model. The final output of the model ensemble produced information about the potential variations of the water balance components (e.g. river discharge, groundwater level and volume) due to climate change. Such projections were used to develop potential hazard scenarios for the case study area, to be further applied within climate change risk assessment studies for groundwater resources and associated ecosystems. This paper describes the models' chain and the methodological approach adopted in the TRUST project and analyzes the hazard scenarios produced in order to investigate climate change risks for the case study area.

The aims of this work are (a) to reconstruct the channel adjustments that have occurred during the last decades and (b) to analyse the present condition of the river in terms of bedload transport and sediment sources. The study reach, which is 23 km long, was investigated using historical maps, aerial photographs, 12 monumented cross-sections, laser altimetry data and field survey. Bedload transport rates were estimated by a morphological approach, which allows the construction of a sediment budget.Dramatic channel adjustments have occurred in response to an alteration of sediment fluxes caused by different human interventions (gravel mining, dams, torrent-control works). Major channel adjustments, specifically incision (up to 8–9 m) and narrowing, took place between the 1950s and the 1980s. On the other hand, widening has become the most important process, and incision has continued only in the upper part of the study reach in more recent times (about the last 20–25 years).The estimate of bedload transport rates for the period 1984–1997 was carried out starting from the erosion and deposition volumes of the single sub-reaches. Such an estimate has shown that (a) a high spatial variability of gravel transport rates exists (from 0 up to 73 200–85 400 m3/year) and (b) most of the bedload is supplied by local sources. Bank erosion is the main source of sediments for bedload transport and its contribution can be estimated as from 9 up to 20 times higher than the upstream contribution. Finally, from a practical point of view, results from this study should be taken into account in addressing maintenance, sediment management and restoration along a dynamic and unstable river such as the Brenta.
