Transformations in hydrological resilience: Unraveling the impact of landscape hydric potential on flood dynamics: A case study, Drwinka catchment (Poland).

Flooding remains a critical issue in urban catchments, driven by complex interactions between land use changes, hydrological dynamics, and environmental factors. This study aims to investigate how modifications in Landscape Hydric Potential (LHP) affect flood behavior in the Drwinka River catchment in Krakow, Poland. Given the rapid urbanization and its impacts on hydrological systems, understanding these changes is essential for effective flood management and mitigation.

Possibility of using the STORAGE rainfall generator model in the flood analyses in urban areas.

In this investigation, we evaluated the applicability of the Stochastic Rainfall Generator (STORAGE) as a data source for deriving design hydrographs in urban catchments. This assessment involved a comparison with design rainfall calculated using Intensity-Duration-Frequency (IDF) curves derived from observed time-series data. The resulting design rainfall values from both methods were incorporated into a hydrodynamic model of the storm sewer network.

Blue-green roofs as nature-based solutions for urban areas: hydrological performance and climatic index analyses.

The water-regulating capacity of nature-based solutions (NBSs) plays a crucial role in providing a full range of ecosystem services and enhancing the resilience of urban systems. This work focuses on the hydrological performance of a particular NBS, the so-called blue-green roof (BGR). The BGR is designed to collect infiltrated rainfall in a water storage layer beneath the soil to support vegetation maintenance, enhance evapotranspiration and cooling, and minimize runoff and drainage system load.

Investigating runoff formation dynamics: field observations at Cape Fear experimental plot.

In this paper, we explore the dynamics of surface runoff formation in an outdoor experimental plot, Cape Fear, by reporting the relationships among rainfall, runoff, and soil moisture for 101 rainfall-runoff events observed in the time span of more than five years (January 2014-March 2019). Cape Fear is a recently developed 7 × 7 m experimental plot that combines features from both small scale facilities and catchment-scale experimental hillslopes, thus leveraging observation of major hydrological variables at high temporal and spatial resolution. Despite the small dimension and simplicity of the plot, the relations among hydrological variables are unexpectedly quite spread.

Assessment of stormwater runoff management practices and BMPs under soil sealing: A study case in a peri-urban watershed of the metropolitan area of Rome (Italy).

By 2006, almost 100,000 km of EU soil (2.3% of the whole territory) had been sealed, with a per capita quota of 200 m of sealed surface for each EU citizen. Italy, in 2016, recorded a soil sealing rate of 2.

Cape Fear: monitoring basic hydrological processes in an outdoor hillslope plot.

Cape Fear is an outdoor 7 × 7 m hillslope laboratory located at the University of Tuscia, Viterbo, Italy, and is equipped with real-time monitoring sensors used to analyse runoff generation. In this paper, hydrological phenomena that occurred during Cape Fear's first 2 years of operation are reported to provide insight into the basic dynamics underlying the hydrological response at the hillslope scale. Based on our findings, surface and subsurface runoff are likely driven by rainfall-threshold phenomena, and evapotranspiration phenomena account for more than 70% of rainfall water input.

Integrated system of phytodepuration and water reclamation: A comparative evaluation of four municipal wastewater treatment plants.

In dry regions, water resources have become increasingly limited, and the use of alternative sources is considered one of the main strategies in sustainable water management. A highly viable alternative to commonly used water resources is treated municipal wastewater, which could strongly benefit from advanced and low-cost techniques for depuration, such as the integrated system of phytodepuration (ISP). The current manuscript investigates four Italian case studies with different sizes and characteristics.

Integrated System of Phytodepuration for Agroindustrial Wastewater: Three Different Case Studies.

The effluents deriving from agricultural industries are sources of wastewater sensibly different from common civil wastewater treatment plants effluents, because they are characterized by significant amounts of nutrients and organic load. Agricultural industries require considerable water volumes for processing the farm products, in doing so generating huge volumes of wastewater, with high concentration of chemical oxygen demand (COD), nitrogen (N) and phosphorus (P). Advanced and low cost techniques for water depuration are required in such circumstances, as the use of Integrated System of Phytodepuration (ISP).

The Integrated System of Phytodepuration of Sile River Natural Park.

The water conservation topic is likely to become increasingly important and alternative water resources employment should be considered as one possible response to the challenges of fresh water demand and environmental protection; among alternative water sources, municipal wastewaters represent one of the most profitable source but in order to reuse them they need adequate and advanced depuration techniques, such as the use of Integrated System of Phytodepuration (ISP). Across a 3-year sampling period, the performances of an ISP within the Natural Park of the Sile River in the Northern Italy were evaluated, analyzing raw wastewater and final effluent characteristics according to the recommendations of European and Italian legislation. The investigated ISP represents one of the first attempts designed in Italy to improve the efficiency of an existing wastewater treatment plant, able to serve 8000 equivalent inhabitants.

Linking phosphorus export and hydrologic modeling: a case study in Central Italy.

Soil erosion is an open topic, not only because soil fertility is lost, but also because nutrients are spilled into water bodies, thereby causing pollution. Research carried out in this field has amply described this process, but the interaction between these factors is complex and experimental research is needed to understand the production of loads of nutrients for different land uses. This paper describes a long-term monitoring case study using high-resolution rainfall data and runoff samples, carried out in the Lake Vico basin (Central Italy) to determine the phosphorus (P) export during erosive rainfall events.
