Abstract:
Morphometric analysis of Holocene pebbles from Sava River gravel in NW Croatia revealed shape distributions as observed along a 30 km long watercourse. Limestones, dolomites, and sandstones were identified as the major (>4%) and effusive magmatics in this alluvial aquifer system in Zagreb, with cherts and tuffs as minor pebble lithologies (up to 4%). Their distributions mainly indicate distant Alpine provenance for carbonate pebbles (limestone and dolomite) and local input for sandstones and minor lithotypes, laterally from the Samoborska Gora and Medvednica mountain. Carbonates are predominantly disc- and sphere-shaped, implying distant sources. Scattered distributions of pebble shapes (sphere, disc, blade, and rod) for sandstones and minor lithotypes possibly indicate multiple sources, some of them probably local. The tentatively interpreted “original sedimentary environments” for the main pebble lithotypes (calculated from their flatness ratios) possibly indicate that they are predominantly lake beach pebbles, followed by moraine and riverbed pebbles. However, these results should be strongly questioned.

Abstract:
The impact of the harbor built near the Mzymta river mouth on the pebble sediment transport along the coast and the coastal line transformation is assessed proceeding from the survey data comparison. Sediment accumulation in the wave chamber of the permeable southwestern barrier pier are considered and the possibility of its circumvention by pebble material is estimated. It is shown that the sediments transported along the pier penetrate into the numerous canyon openings and go deeper. As a result of the bottom erosion behind the port, the pebble beach in front of the shore-protective structure protecting the embankment from the waves has disappeared at the 1-km-long coast site, and its erosion continues. The absence of a wave-setting pebble beach poses a threat to the destruction of the coastal protection structure and the embankment.

Abstract:
ABSTRACT On January 31, 1988, the Amazzone spilled about 1,500 tons of a highly paraffinic medium fuel oil (having a pour point of 36°C) along a distance of 300 km off the coast of Brittany. Due to very rough sea conditions, no offshore recovery operation could be carried out. Most of the pollution was beached as scattered patches on numerous sites, including pebble beaches in south Finistère, which had been especially difficult to clean during previous spills. In this area, the pebble banks that protect the dunes are relatively exposed to erosion. It was therefore decided to try cleaning these pebbles on site using the mobile plant that was designed for washing polluted sands and tested in 1985. The plant prototype was put in working order and conveyed to the site on the Baie d'Audierne. The equipment was very easily adapted to washing the pebbles polluted by a mixture of sand and fuel oil emulsion. A total of 1,400 m3 was cleaned during 10 days at the end of March. The plant worked smoothly with a load of 20 to 25 m3 of pebbles per hour and using a petroleum solvent as a washing agent. Because the ambient temperature was rather low (around 5°C), cleaning was performed with warmed water. Compared to other techniques that could be used to clean polluted pebble beaches, the washing plant proved very effective (providing good cleaning and high throughput) and competitive (costing less than quicklime treatment, for instance). Another advantage of this technique is that cleaned pebbles are returned to the beach, helping the pebble bank to keep its anti-erosion function.

Abstract:
The Albany Beach Restoration Project was initiated with the goal of stopping landfill erosion into San Francisco Bay, while creating aquatic habitat, and nourishing a pocket beach at McLaughlin Eastshore State Park, Albany, California. The site contains an existing sandy pocket beach which is unique to San Francisco Bay, and was formed by construction of the Albany Neck and Bulb, which was created as a landfill. Coastal engineering analysis, numerical modeling of coastal processes, and pocket beach morphology modeling were performed to evaluate and protect against erosion on the Albany Neck and prevent contaminant entry to the Bay, evaluate potential enhancement alternatives for the sandy pocket beach, and develop design criteria for living shorelines structures/habitat elements. In addition, analysis was performed to evaluate the stability of living shoreline structures, including a crescent reef with oyster shell nourishment, a pebble beach and groin system, avian roosting islands/breakwater elements, and tidepools.

It’s difficult and uneconomic to promote the construction of sewer system in the areas with low population density, especially in rivers upstream with abundant agricultural activities. Without proper treatment, the sewage discharged into the surface water bodies may cause, different levels of water pollution, increase the environmental loadings, and deteriorate river water quality. In this light, the aeration biological attached-growth technique can be applied to improving the aquatic pollutant of the river upstream, especially for the sewage agricultural wastewater and surface runoff. Along the context, this study focused on the evaluation of the synthetic wastewater treatment capability of the aeration biological attached-growth technique at different operation conditions of, influent loadings at the carbon:nitrogen:phosphorus (C:N:P) ratio of 100:15:3. The result from this study indicated that the biochemical oxygen demand (BOD) removal efficiency ranged from 83.14% to 98.28%.The chemical oxygen demand (COD) removal efficiency was observed between 75.64% and 96.56%. The total organic carbon (TOC) removal efficiency was between 80.24% and 97%. All the observed results were at the experimental condition of 1, 2 and 3 hours hydraulic retention time, and influent COD concentrations no more than 250mg/L. When the influent COD concentration was 300mg/L at the hydraulic retention time of 1, 2, 3 hours, the BOD, COD and TOC removal reached 67%~81%, 63%~75%, and 68%~85%, respectively. Obviously, the removal rate may decrease when the influent COD was above 250mg/L implying that increase in hydraulic retention time was required when contamination loading is comparatively high. Another experimental study at the influent COD concentration of 200mg/L, 250mg/L, and 300mg/L at the C:N:P of 100:15:3 at 1, 2, 3 hours hydraulic retention time without aeration indicated that the un-aerated, system was demonstrated to have the BOD removal efficiency between 49% and 79%. For COD, the removal rates were 34% to 66%. For TOC, the removal rates were 55% to 82%. Less dissolved oxygen resulted in less contaminant removal rate. Generally, increase in hydraulic retention time may increase the contaminant removal rate. For organic contaminants, the microorganism digested the organic substrates through enzymatic reactions. For COD, better removal was observed as the hydraulic retention time increased since more contact time would favor the occurrence of physical interactions of sedimentation, filtration and sorption. The removal efficiencies of NH3-N were more than 95% in the tests of the elevated nitrogen and phosphorus content at the influent COD concentrations of 50mg/L, 100mg/L and 150mg/L. The NH3-N removal efficiencies were more than 76.56% when the influent COD concentrations were 200mg/L, 250mg/L and 300mg/L. However, at the same influent COD concentration, the tests with C:N:Pratio of 100:15:3 showed a higher nitrogen removal efficiency (ranging from 76.56% to 96.87 %) compared to those with C:N:P ratio of 100:5:1, which had the removal. more than 95.47% in general. With the same experimental conditions except for different nitrogen and phosphorus content, the removal efficiencies of NH3-N were more than 95.5% for both aerated and un-aerated systems. For the un-aerated system with influent COD concentrations of 250 and 300mg/L had the NH3-N removal rate between 72.48% and 88.05%, only the test with influent COD 200mg/L and 3 hours retention time had the, NH3-N removal of 96.9%. In general, the NH3-N removal rate shall increase at the hydraulic retention time increases.Meanwhile, no NO2--N and NO3--N were observed, suggesting that NH3-N might be removed through microbial adsorption, rather than nitrification process which might be inhibited in the environment where the pH was less than 5. The orthophosphate (PO43-) was removed effectively by the attached-growth biofilm system through microbial intake and adsorption. For the experiments at influent COD concentrations from 50mg/L to 250mg/L with the C:N:P ratio of 100:15:3, more than 90% removal was observed at the hydraulic retention time of 2 hours. Further increase in hydraulic retention time to 3 hours resulted in the 93% phosphorus removal. For the influent COD concentrations of 200mg/L, 250mg/L and 300mg/L and C:N:P ratios of 100:15:3 and 100: 5:1, the phosphorus removal was comparatively higher (ranging from 83.48% to 94.23%) while the C:N:P ratio was 100:15:3. The PO43- removal ranged from 90.07% to 97.71% when the C:N:P ratio was 100:5:1. The experiments for higher nitrogen and phosphorus content had the PO43- removal rate ranging from 90.07% to 97.71%. Similarly, better removal was observed for the system with longer hydraulic retention time. For the influent COD concentration of 200mg/L, 250mg/L and 300mg/L, C:N:P ratio of 100: 5:1, the removal efficiency of PO43- were more than 90% for the system with enhanced aeration, and the removal rate of PO43- ranged between 82.79% to 96.55% for the un-aeration system. The PO43- removal rate for un-aeration systemwas significantly lower than that with aeration. The microbial community in the biofilm system was quite complex, and it may vary as the environmental conditions changes. In the study, one biofilm sample was collected for microbial identification. The strain identified Enterobacter sp. FC1, was a Gram-negative bacteria with bacilli, and moves by its flagellum. Enterobacter is an anoxic/anaerobic bacterium and can ferment lactose quickly (e.g., colibacillus and Klebsiella bacilli). They exist in wastewater treatment system and is distributed extensively as a common musculomyces.

Abstract:
The pebble is on the beach, once more, unmarked by its brief contact with human sentience. Almost unmarked. The fingerprints that it lightly bears will, however, be washed away by the next tide. It has a long future, still, but probably not as a pebble—though quite how long it remains as a pebble may well depend on human action. Not on immediate, direct human action—whether it is scooped up by a digger and converted into concrete for a sea-front esplanade, for instance, or even collected as a souvenir by some passing tourist. Either of these fates should cause only a brief deflection from its long-term future (the esplanade is, after all, only a cliff to be attacked by the elements, while beach souvenirs are soon discarded). A larger perturbation of its trajectory more probably hinges on wider human effects—but more of that anon. We might assume, first, that nature runs its course. A pebble on a beach, its natural environment, is changing all the time. Not long ago, it was part of a slab of slate in a cliff, then it briefly became an angular chunk of rock, before the waves and water smoothed it down. They are still smoothing it, wearing away at it, making it smaller. Even the contact with human hands probably removed a grain or two. A pebble has the appearance of permanence, but it is not permanent. How long does it take to wear down a pebble? This can happen astonishingly quickly. Even over a single tide, being washed backwards and forwards by every incoming wave, a pebble can become detectably lighter—by less than one tenth of one per cent, admittedly, but that weight difference can easily be measured using modern electronic scales. Over a season, on an exposed part of the coast, a pebble can lose between a third and a half of its mass. The rates will vary—on a stormy day the banging of pebbles against each other can produce distinct percussion marks on their surfaces, while on a calm day the attrition rate will drop markedly. Night and day, though, the pebble is disintegrating.

Abstract:
Some things are just infuriatingly difficult to pin down in geology. For instance, just how deep was our pebble sea, the Silurian sea of the Welsh Basin at the spot that became, some 400 million years later, the beach beneath our feet? Well, one can estimate some kind of minimum depth. It was deeper than the depth to which waves and tides can leave a trace on a sea floor, because no traces of these phenomena have been found in the pebble stuff or—rather more convincingly as evidence—in any of the strata of those Welsh cliffs from which the pebble could have been derived. As a rule of thumb, that means that the sea was more than a couple of hundred metres deep, that being the depth to which the very biggest waves of the very biggest storms on a wide open sea can stir the sea floor. Now, if strata have been deposited above that level, then one can make some reasonable estimates of ancient water depth. Thus, if one finds fossilized beach-strata, that is an obvious signal that those rocks were formed virtually at sea level. And below that, we can make a distinction between those shallow sea floors that are stirred pretty well all the time, even by the small waves of a fair-weather day (on this kind of sea floor, mud is winnowed away, and only sand and pebbles can settle); and those deeper sea floors only affected by the biggest storms (where thick muddy layers can settle in between major storms that may have been a decade—or a century—apart). But below even that? It is, in practical terms, hard to tell from the rock strata whether the ancient sea floor on which they were laid down was 300m or 3000m deep, or perhaps even more. So it is with the pebble rock. This Welsh sea floor was deep in general terms, but its precise depth remains a mystery—working out even a reasonably imprecise depth remains as a puzzle for future generations of geologists to solve.

Abstract:
Before any great expedition, there is a gathering of all of the forces—of the clans, the troops, the mercenaries—from near and far, by various routes. Once met, they will then travel en masse, their fortunes from then to be bound together, for good or ill. Sediment particles of the future pebble were gathering, around the shores of Avalonia, in the Silurian Period, for a journey that would take them to a resting place, one where they would not see the light of day for something over 400 million years. The grains of sand and flakes of mud, with all their variety and histories, were being washed into some long-vanished shoreline by Avalonian rivers, rivers that have not yet been discovered, or charted, or named, by modern-day explorer–geologists. Likely these rivers never will be charted, for in flowing they eroded themselves away, washing away their own tracks, as Avalonia was being dismantled, grain by grain, by the eternal, tireless action of the weather. All that is left is the freight they carried, the baggage of sand, mud and pebbles. The ancient shoreline lay not much more than 50 miles away from what is now our pebble beach in west Wales. It lay to the south, around what is now Pembrokeshire in South Wales. What did it look like, that ancient coastline? Well, it may even have resembled the rugged Pembrokeshire coastline of today, though it faced north rather than south, looking across an area of open sea that was later transformed into the Welsh mountains. For the pebble stuff, the passage across that coastline marked the entrance into a new realm. As the river waters entered the sea, their onrush slowed. The sediment grains, no longer driven by river flow, would have piled up around river mouths as deltas, or within silting-up estuaries. They would not have been stilled for long though, for coastlines are places where energy is exchanged. New forces acted on these sediment particles: wind and tides and waves, the forces that nowadays mariners need to respect, and understand, and predict.

Abstract:
What is a pebble? It is a wave-smoothed piece of rock, and a complex mineral framework, and a tiny part of a beach, and a capsule of history too. All these guises have their own stories, and these we shall come to. But from yet another viewpoint the pebble is a collection of atoms of different kinds—of many, many atoms—and that might be the best way to start. Considering it at this level, it is a little like taking the equivalent of a large sack of mixed sweets and separating them out into their different types. How big a sack, though? Or, to put it another way, how many atoms in our pebble? There is a simple formula for estimating the number of atoms in a piece of anything. The basic idea was first glimpsed by Amadeo Avogadro, Count of Quereta and Cerreto in Piedmont, now Italy: scholar, savant and teacher (though his teaching was briefly interrupted because of his revolutionary and republican leanings—a little impolitic when the king lives nearby). Avogadro was interested in how the particles (atoms, molecules) in matter are related to the volume and mass of that matter. Years later, his early studies were refined by other scientists and the upshot, a century or so later, came to be called Avogadro’s constant. Thus, in what is called the mole of any element there are a little over 600,000 million million million—or, to put it more briefly, 623—atoms. A mole here is not a small furry burrowing quadruped, or a minor skin blemish, but the atomic weight of any element expressed in grams. For oxygen a mole would therefore be 16 grams, as 16 is its atomic weight, an oxygen atom having a total of 16 protons and neutrons in its nucleus. The kitchen scales tell us that our pebble weighs some 50 grams. About half of it is made up of oxygen, and much of the rest is silicon (atomic weight 28) and aluminium (atomic weight 27) with a scattering of other elements, most somewhat heavier. A judiciously averaged atomic weight might therefore reasonably be something like 25.

Abstract:
In Barra De Cazones, Veracruz, we ordered Modelos at an empty beach­front restaurant, La Palapa de Kime, on a muggy July afternoon. A handful of vacationers were scattered on the expansive, pebbled, brown sand beach. This was not the tropical paradise of Cabo San Lucas brochures—with expensive hotels and fine white sands—but the scarcity of tourists in this beautiful and serene Gulf Coast village was puzzling at first glance. The roads into town are good—pleasant, twisting runs through a remote and picturesque rainforest, in fact—and a couple of medium-sized cities and an airport are within an hours’ drive. We later learned that the electricity in town was sporadic and that the hotel accommodations were expensive but shoddy. And along the downtown strip, half-constructed buildings seemed frozen in their incompleteness, as if they were as ambivalent about the future as the inhabitants were. Roofless, these cinderblock buildings stood mute and abandoned alongside the central beachfront road, rusting rebar jutting out of the tops of their gray walls. In front of them, stacks of bricks lay idly on the sidewalk. This quiet fishing and farming village of a few thousand would like to reinvent itself as a tourist destination. Government efforts to create fishing cooperatives and plants for processing and freezing fish expanded Mexico’s annual catch in the 1970s and 1980s, but today Mexico’s coasts are dominated by U.S., Canadian, and Japanese boats, which catch ten times what Mexican boats do. Small-scale fishermen in places like Barra de Cazones fetch low prices for their fish, and high fuel prices take a sizable chunk of their meager earnings. With fishermen struggling, little investment in infrastructure, high interest rates, and few jobs, this lonely town’s main business, like that of the nearby villages of Volador and Agua Dulce, is out-migration. Archimedes, a proud and boisterous local entrepreneur, was frying several freshly caught fish in a wide skillet and extolling their virtues in a theatrical baritone.

Abstract:
We are on more familiar ground in this chapter, looking at processes and materials found in the world all around us. Even the names of sedimentary rocks are well known—sandstone, shale, limestone, and so on. Clearly, these materials are highly relevant to vineyard geology because more than three-quarters of the land surface is sedimentary in origin: most of the world’s vineyard areas are underlain by sedimentary rocks. Sediment is the detritus produced from the weathering of already existing rocks. (I explore the process in Chapter 9.) Usually, wind, ice, or water soon moves the debris away, eventually to be deposited and then buried beneath further sediment and with time hardened into sedimentary rock. Weathering can also dissolve material, later to be precipitated. And, needless to say, all the sediment in question here is of geological origin; it has nothing to do with the organic sediment that is thrown, say, in a bottle of vintage port! Wind and flowing water may be able to pick up sediment and move it, depending on the size of the fragments. Faster-moving currents can carry bigger particles: it’s to do with energy, as discussed in the context of rivers in Chapter 8 (see Figure 8.8). The result is sediment sorting. We can easily see the results on a beach—a sandy spot here, a pebbly patch there—because the tides and shore currents have moved the sediment around and sorted it. Thus, most detrital sediments have a characteristic grain size, and we use this to classify the material. The terms for the different sizes are pretty much in line with everyday language: sand, silt, clay, and so on (Figure 5.1). Clay is the finest sediment. It’s composed mainly of the tiny clay minerals that we met in Chapter 3 and has the smooth, slippery feel and handling properties we’re all familiar with; the individual constituent particles are far too fine to see, even with a powerful hand lens. Imagine: if we scaled up a grain of sand to the size of a wine cask, then an individual clay flake would be smaller than a coin.

Abstract:
The Imeretinsky lowland – the central fragment of a large Black Sea terrace of the Caucasian coast of Russia, is located in interfluve the rivers Mzymty and Psou. In its central and western part large sports complexes of the winter Olympic Games "Sochi-2014" and the Olympic village are under construction. It has led to necessity of engineering protection of coast from the constructed port Imeretinsky to east board of cape of Konstantinovsky. In the report the site located from the Southern pier of port to the western board of cape of Konstantinovsky is considered. On a site the underwater canyon Novuy is located. To provide stability of a shore, the project of coastal protection now is realized. This project provides building in a surface part of a beach ferroconcrete grille on piles and a slope from concrete cubes. Before should be fill an artificial pebble beach in width not less than 50 m. As has shown inspection of coastal protection constructions, rates a beach lag behind rates of its washout. The width of a surface beach makes now no more than 13 m. For scoping executed embankments sandy a material comparison bathymetric shootings before port building (2007) has been made and April, 2012. By comparison is established that slept pebble the material is at the bottom and doesn't move waves on coast. Thus, massed filling the pebble material, coasts of Imeretinsky lowland spent recently on a considered site, haven't led to formation of a steady surface beach in design width of 50 m. On this site, and also on a site around Konstantinovsky's canyon updating of design decisions is required.

Abstract:
Within the framework of the monthly monitoring the study of qualitative and quantitative composition and distribution of micro- and small macroplastic on sandy and pebbly beaches of Sevastopol is initiated. Microplastics and small macroplastic abundance was estimated from surveys on two of the most popular Sevastopol sandy beaches of the Crimea Black Sea Coast (Omega beach and Uchkuyevka beach). The samples were collected during March - April 2016 from the top 5 cm of the numerous square areas (1×1 m) placed on 20 m long transects perpendicularly 100-meter lines along the shore line. Three type of stainless steel sieves were used: mesh sizes 5 mm, 1 mm and 0,3 mm. In the laboratory, the collected sediments were introduced into a glass tank with a high concentration solution of sodium chloride (NaCl) 140 g l-1, the floating plastic particles recovered, sorted and categorized by type, usage and erosion level. The mean microplastics densities on Omega and Uchkuyevka Beach were 4,2 ± 0,95 and 2,6 ± 0,95 items m-2, accordingly. Most of micropastics items were rigid fragments (60%), polystyrene (25%) and polyethylene (15%). Number of macroplastic particles (size of 5-100 mm) by 1 m-2 ranged from 2.35 to 57, the mean abundance on Omega and Uchkuyevka beaches were 10,1 ± 0,95 and 7,3 ± 0,95, accordingly.
