Hydrological Effects

<p>Surface runoff rates in torrents are driven by land use and climate changes. Moreover, the effects of control works, such as the check dams, can modify these rates. In the Mediterranean semi-arid watersheds (e.g., in Southern Italy and Spain), this forcing may sum to local factors, such as steep slopes, small drainage areas and heavy and short-duration rainstorms. Therefore, it is important to evaluate the hydrological effects of each action (presence of check dam, land use changes and future climate forcing), in order to control flash floods, soil erosion and landslides at the watershed scale. To this aim, this study evaluates the annual runoff rates in two headwaters of Southern Italy, mainly forested and agricultural, using a modeling approach. More specifically, the well-known Soil and Water Assessment Tool (SWAT) model is applied to Vacale (12.5 sq. km) torrent, regulated by check dams built in ‘1950-1960, and Serra torrent (13.7 sq. km), not regulated. Both sub-watersheds experienced an increase in forest cover up to 70%, while the agricultural land decreased by about 30% of the total area in the period after the construction of the control works until now. Previously, the model was calibrated in a third torrent (Duverso, 12.5 sq. km, gauged for runoff measurements), with the same climatic and geomorphological characteristics, using the automatic calibration by the SWATCUP program. After calibration, SWAT simulated the hydrological response under different land uses (forest, pasture and bare soil, the latter simulating total deforestation) and climate change scenarios (applying a Global Circulation Model, under 2.6 and 8.5 Representative Concentration Pathways) throughout the next 80 years. The results of this modeling experience showed that: (i) the presence of check dams noticeably reduced the hydrological response of the regulated headwater compared to the torrent without check dams; (ii) the vegetal cover of the forestland has been the most important factor in mitigating the surface runoff rate in comparison to the other land uses; (iii) under the future climate change scenarios, the surface runoff will increase with increasing mean temperatures and precipitation intensity. The model outputs help supporting a better understanding on the impacts of control works as well as land use and climate changes on the runoff generation capacity in Mediterranean torrents. These indications are useful to watershed managers in the adoption of the most effective strategy to mitigate flash flood hazards and heavy erosion risks in similar environmental contexts. </p><p>Acknowledgement: This research was funded by ERDF/Spanish Ministry of Science, Innovation and Universities-State Research Agency (AEI) /Project CGL2017-84625-C2-1-R; State Program for Research, Development and Innovation Focused on the Challenges of Society.</p><p> </p>

In river basins, the deep interrelationships between land-use changes, soil erosion and rivers and shoreline dynamics are clearer than at a national or regional scale. Southern Italy is an ecologically fragile, desertification-prone territory where land-use changes in the last decades were significant. Notwithstanding this, studies dealing with multidecadal land-use changes in large-sized river basins of Southern Italy and their implications on soil erosion are missing. In this study, we assessed the land-use changes that occurred between 1960 and 2012 in the 3245 km2-wide Sele River basin. We carried out GIS-aided comparisons and analysis of two land-use maps and interpreted the results in terms of soil erosion intensity based on a detailed review of the scientific literature. The results confirmed the trend of the inner areas of Italy and, in particular, of the Campania region moving towards more pristine conditions, with an increase in forest cover, mainly at the expense of grasslands. Agricultural areas remained substantially unchanged, while the area of urban settlements increased. The diffuse afforestation of slopes suggested an overall decrease in soil erosion intensity, which was fully coherent with the geomorphological evolution of both the Sele River and local shoreline reported in literature.

Abstract. Bantul Regency is a part of Yogyakarta Special Province Province which experienced land use changes. This research aims to assess the changes of shape and level of land use, to analyze the pattern of land use changes, and to find the appropriateness of RTRW land use in Bantul District in 2011-2015. Analytical methods are employed including Geoprocessing techniques and analysis of patterns of distribution of land use changes with Spatial Autocorrelation (Global Moran's I). The results of this study of land use in 2011, there are thirty one classifications, while in 2015 there are thirty four classifications. The pattern of distribution of land use change shows that land use change in 2011-2015 has a Complete Spatial Randomness pattern. Land use suitability with the direction of area function at RTRW is 24030,406 Ha (46,995406%) and incompatibility of 27103,115 Ha or equal to 53,004593% of the total area of Bantul Regency.Keywords: Geographical Information System, Land Use, Geoprocessing, Global Moran's I, Bantul Regency. Abstrak.

Interest in land-use changes (LUC) research has been growing rapidly in recent years. This topic has already become the subject of a separate scientific discipline – land use science (or land change science). In order to formulate relevant future policy and develop appropriate land-use management tools, it is crucial to know how the LUC шьзфсе the environment and society condition. For Ukraine, where the structure of land use and the system of land resources management have significantly changed during the years of post-socialist transformation of land relations, the study of the LUC on a modern methodological basis is especially actual. The paper, based on a critical analysis of publications in leading international journals over the last thirty years, identifies key directions of LUC studies and analyzes their methodological features. There is a significant increase of the number of works based on the results of meta-studies and the use of a wide range of methods for modeling the LUC processes, their causes and possible consequences. The great "synergistic potential" of integration of the selected directions is noted, which makes it possible to accelerate the development of the general theory of land use and increase its use efficiency in substantiation of management decisions in the sphere of land use and modernization of the mechanisms of state land, spatial and ecological policies with consideration of existing and potential globalizing challenges. In this context, the key role of the land use integrated planning methodology at regional and local levels is emphasized. This methodology would require close cooperation between government, business and the public in developing a common vision for the implementation of specific land use plans and projects based on the principles of subsidiarity, participativity and shared responsibility.
