Dredging has a significant effect on sediment transportation, water quality and flow conditions in river channel. However, often the effects of dredging are not studied carefully advance. One reason for this is lack suitable study approach. Studies dynamics require high geometric models riverbed, banks floodplain. Accurate terrain bathymetric data also crucial components reliable hydraulic mode...

Conventional dredging of ditches and streams to ensure agricultural drainage flood mitigation can have severe environmental impacts. The aim this paper is investigate the potential benefits an alternative, nature-based two-stage channel (TSC) design with floodplains excavated along main channel. Through a literature survey, investigations at Finnish field sites expert interviews, we assessed pe...

Abstract Context Landscape modification alters the condition of ecosystems and structure terrain, with widespread impacts on biodiversity ecosystem functioning. Seafloor dredging a diversity flora fauna in many coastal landscapes, these processes also transform three-dimensional terrain features. The potential ecological significance changes urban seascapes has, however, not been investigated. ...

In randomized experiments, it is often of interest to characterize treatment effect heterogeneity in terms of baseline covariates. Usually, the aim is to identify subpopulations likely to have particularly positive or negative (or neutral) responses to treatment. The process of searching for such subpopulations after the completion of an experiment (without pre-specifying which subpopulations w...

After Typhoon Morakot, dredging engineering was conducted while taking the safety of humans and structures into consideration, but partial stream reaches were formed in the multiple-channel sections in Cishan Stream because of anthropogenic and natural influences. This study mainly explores the distribution of each fish species in both the multipleand single-channel sections in the Cishan Strea...

effects of sound on Aquatic life Current expansion of offshore industrial activities has led to concern about the impact of man-made sounds upon marine animals (Southall et al., 2007; Hastings, 2008; Popper and Hawkins, 2012, 2014). Offshore oil and gas exploration and developments, wind farm construction and operations, other renewable energy sources, dredging, construction activities, naval s...
