The shear stress at the bed of a channel influences important benthic processes such as sediment transport. Several methods exist to estimate the bed shear stress in bare channels without vegetation, but most of these are not appropriate for vegetated channels due to the impact of vegetation on the velocity profile and turbulence production. This study proposes a new model to estimate the bed shear stress in both vegetated and bare channels with smooth beds. The model, which is supported by measurements, indicates that for both bare and vegetated channels with smooth beds, within a viscous sub-layer at the bed, the viscous stress decreases linearly with increasing distance from the bed, resulting in a parabolic velocity profile at the bed. For bare channels, the model describes the velocity profile in the overlap region of the Law of the Wall. For emergent canopies of sufficient density (frontal area per unit canopy volume a >/= 4.3m⁻¹ ), the thickness of the linear-stress layer is set by the stem diameter, leading to a simple estimate for bed shear stress.

Повний текст джерелаThis review paper addresses the structure of the mean flow and key turbulence quantities in free-surface flows with emergent vegetation. Emergent vegetation in open channel flow affects turbulence, flow patterns, flow resistance, sediment transport, and morphological changes. The last 15 years have witnessed significant advances in field, laboratory, and numerical investigations of turbulent flows within reaches of different types of emergent vegetation, such as rigid stems, flexible stems, with foliage or without foliage, and combinations of these. The influence of stem diameter, volume fraction, frontal area of stems, staggered and non-staggered arrangements of stems, and arrangement of stems in patches on mean flow and turbulence has been quantified in different research contexts using different instrumentation and numerical strategies. In this paper, a summary of key findings on emergent vegetation flows is offered, with particular emphasis on: (1) vertical structure of flow field, (2) velocity distribution, 2nd order moments, and distribution of turbulent kinetic energy (TKE) in horizontal plane, (3) horizontal structures which includes wake and shear flows and, (4) drag effect of emergent vegetation on the flow. It can be concluded that the drag coefficient of an emergent vegetation patch is proportional to the solid volume fraction and average drag of an individual vegetation stem is a linear function of the stem Reynolds number. The distribution of TKE in a horizontal plane demonstrates that the production of TKE is mostly associated with vortex shedding from individual stems. Production and dissipation of TKE are not in equilibrium, resulting in strong fluxes of TKE directed outward the near wake of each stem. In addition to Kelvin–Helmholtz and von Kármán vortices, the ejections and sweeps have profound influence on sediment dynamics in the emergent vegetated flows.

Повний текст джерелаIl mio progetto di dottorato si è focalizzato sulla caratterizzazione, dal punto di vista biochimico ed elettrofisiologico, di una proteina denominata TPK3 che è predetta di funzionare come canale selettiva per il potassio (K+) ed essere localizzata nei cloroplasti nelle piante superiori,. Questa proteina appartiene alla famiglia dei canali TPK (da Tandem-Pore K+ channels) e mostra omologia di sequenza a un altro canale del K+ studiato nello stesso nostro laboratorio, denominato SynK (Zanetti et al., 2010), a localizzazione tilacoidale ed appartenente al phylum dei Cianobatteri. È stato dimostrato in più esperimenti che il canale SynK è fondamentale per la regolazione della fotosintesi nei Cianobatteri, in considerazione del fenotipo fotosensibile mostrato dai mutanti per il gene synk. Visto la localizzazione predetta del TPK3, è stato ipotizzato in partenza che TPK3 potesse svolgere un ruolo simile nelle piante superiori. Finora nulla si conosceva sulle proprietà di TPK3, ne sui suoi ruoli fisiologici, ne su di un suo eventuale coinvolgimento nella fotosintesi nelle piante superiori; il lavoro contenuto nel progetto presentato ha cercato di chiarire alcuni aspetti salienti delle funzioni di TPK3. Dopo studi di localizzazione subcellulare condotti con tecniche di biochimica e microscopia confocale, il canale TPK3 è stato espresso in E. coli per la successiva caratterizzazione elettrofisiologica in bilayer lipidico planare allo scopo di determinare la sua funzione come canale di K+. L’assenza di mutanti commerciali per il gene tpk3 ha necessitato la messa a punto del suo silenziamento tramite RNA interference del messaggero per la proteina suddetta, al fine di analizzarne i possibili ruoli fisiologici. Le piante silenziate risultanti, sottoposte a differenti condizioni di crescita, sono state studiate in vari esperimenti atti a determinarne vari parametri inclusi quelli fotosintetici. Contemporaneamente allo studio del TPK3, quello di maggior rilievo nel mio dottorato, ho seguito anche altri due filoni di ricerca principali, riguardanti l’uno l’approfondimento delle funzioni di due membri dei Recettori di Glutammato vegetali (GluRs) e l’altro la caratterizzazione degli omologhi del recentemente identificato MCU (Mitochondrial Calcium Uniporter) di Mammiferi. Nella presente tesi è inoltre incluso un manoscritto (Checchetto et al., 2012) per il quale ho collaborato nell’espressione eterologa del canale di K+ calcio-dipendente (SynCaK) di Cianobatteri.
