Nine synthetic bands processed as input data identified most effective for Artificial Neural Network (ANN) classification procedure implemented case study. To assess possible hydrological...

Devastating floods are observed every year globally from upstream mountainous to coastal regions. Increasing flood frequency and impacts affect both major rivers their tributaries. Nonetheless, at the small-scale, lack of distributed topographic hydrologic data determines tributaries be often missing in inundation modeling mapping studies. Advances Unmanned Aerial Vehicle (UAV) technologies Digital Elevation Models (DEM)-based can address this crucial knowledge gap. UAVs provide very high...

Airborne remote sensing systems are increasingly used in engineering geology and geomorphology for studying monitoring natural hazardous scenarios events. In this study, we two techniques, i.e., light detection ranging (LiDAR) unmanned aerial vehicles (UAV) to analyze the kinematic evolution of Montescaglioso landslide (Basilicata, Southern Italy), a large rain-triggered that occurred December 2013. By comparing pre- post-event LiDAR UAV DEMs orthomosaics, delineated morphological features...

Monitoring ephemeral and intermittent streams is a major challenge in hydrology. On-site inspections may be impractical difficult-to-access environments. Motivated by the latest advancements digital cameras computer vision techniques, this work, we describe development application of stage-camera system to monitor water level ungauged headwater streams. The encompasses consumer-grade wildlife camera with near-infrared (NIR) night capabilities white pole that serves as reference object...

The growing concentration of population and the related increase in human activities coastal areas require numerical simulations to analyze effects flooding events that might occur susceptible order determine effective management practices safety measures safeguard inhabited areas. reliability analysis is dependent on correct evaluation key inputs such as return period events, vulnerability exposed assets, other risk factors (e.g., spatial distribution elements at risk, their economic value,...

Soil erosion during rainfall events is affected by several factors, such as topography, soil type, land management, and vegetation cover. In this study, a series of tests investigates the influence selected perennial herbaceous plants with deep strong rooting system, called MC1, on runoff generation erosion. The investigated nature-based solution have been performed in Cape Fear experimental hillslope natural artificial for different heights. For all experiments, runoff, moisture, data were...

The complex interplay between landscape connectivity, climate fluctuations, and land use transformations profoundly affects ecosystem health, functionality, human well-being on a global scale. However, these interconnected issues are often not addressed collectively in studies, conservation strategies, or plans, particularly at the This paper introduces, for first time CCL Nexus - an integrated approach to studying Connectivity, Climate, Land use/cover change relationship better understand...

Landscape restoration projects are among the most extensive conservation actions at global level that have been promoted in last three decades. Such projects, however, cannot exclusively be based on of natural and semi-natural ecosystems, but should focus a cultural landscape approach balancing environmental socio-economic needs. One largest realized five years was World Bank’s Burundi Restoration Resilience Project (PRRPB). PRRPB utilized an integrated to restore social-ecological systems...

The monitoring of small headwater catchment represents a major issue in hydrology, especially remote areas, where gathering real-time hydrological data is often prohibitive due to the limited availability power and connectivity. However, recent advances non-contact computer vision informatic technology offer an opportunity fill such technical gap. In this regard, we designed developed MagicHydroBox prototype (MHB), all-in-one camera processing unit system aimed at water level rivers. tasks...

One of the main issues arising during rapid filling a pipeline is pressure transient which originates after entrapped air has been expelled at release valve. Because difference in density between water and air, impact column. Many authors have analyzed problem, both from theoretical experimental standpoint. Nevertheless, mainly vertical or horizontal pipelines analyzed, whereas real field applications, pipe profile sequence ascending descending pipes, with release/vacuum valves high points....

Aim of the study: Arid and semi-arid lands often face a shortage freshwater due to uncontrolled runoff. In arid regions Africa, rainwater harvesting is promising solution that can be implemented for multiple purposes such as agriculture, recreation, flood control, drinking water. This study highlighted numerous benefits bridge gap between water demand availability. Although scarcity remains major constraint life economic development, it an obvious fact Africa are slowly adopting effective...

Rainfall-runoff modelling in small and ungauged basins represents one of the most common practices hydrology. However, it remains a challenging task for researchers practitioners, particular climate change context areas subject to drought risk. When discharge observations are not available, empirical or event-based approaches commonly used. these schemes can be affected by several relevant assumptions. In last years, continuous models have been developed order address major drawbacks...

Estimating economic losses caused on buildings and other civil engineering works due to flooding events is often a difficult task.
