Abstract
Vegetation growth along rivers may have effects on water resistance and velocity distribution. Roughness evaluation is crucial in constructing river stage-discharge curves, due to its great importance in river management and risk assessment. Usually, land managers mechanically remove vegetation to increase flow conveyance and reduce flooding risk, with negative effects on the riverine ecosystem and hydraulic risk downstream.
The study aims to implement a useful methodology for management planning along vegetated riparian zones through the development evaluation of both unmanaged and anthropically disturbed riparian ecosystems, using tree stands quantitative parameters required to estimate roughness caused by riparian vegetation.
For each watercourse, it was also possible to evaluate the equivalent roughness dependent on river morphology and the effective flow resistance over time.
The outputs of vegetation parameters analysis also may provide practical support in gentle maintenance interventions of Tuscan watercourses planning, to ensure positive effects both on water flow and on riverine ecosystem.
期刊介绍：
Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers.
Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
