Hard shoreline engineering is the use of non-organic reinforcing materials, such as concrete, steel, and plastic to fortify shorelines, stop erosion, and protect urban development from flooding. However, as shoreline development among coastal cities increased dramatically, the detrimental ecological factors became apparent.
Sustainable Materials Management is a systemic approach to using and reusing materials more productively over their entire lifecycles. It represents a change in how a society thinks about the use of natural resources and environmental protection. By looking at a product's entire lifecycle new opportunities can be found to reduce environmental ...
Concrete work is efficient and controlled as CCS functions as ready-made forms; CCS with concrete forms a flexible slab that accommodates minor subgrade movement and prevents cracking. In medium and low flow-velocities, CCS with geomembranes and gravel cover can be used to create impermeable channels, thereby eliminating the need for concrete.
A sand dam is a reinforced concrete wall (or a similarly robust and impermeable weir) built 1–5 metres high across a seasonal sand river.. When it rains the dam captures soil laden water behind it – the sand in the water sinks to the bottom, whilst the silt remains suspended in the water.
Unlike most other concrete applications, AAC is produced using no aggregate larger than sand. [25] Quartz sand (SiO 2), calcined gypsum, lime (mineral) and/or cement and water are used as a binding agent. Aluminum powder is used at a rate of 0.05%–0.08% by volume (depending on the pre-specified density).
Retention ponds such as this one in Dunfermline, Scotland, are considered components of a sustainable drainage system. Sustainable drainage systems (also known as SuDS, [1] SUDS, [2] [3] or sustainable urban drainage systems [4]) are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure ...
The way to prevent this is to insert above the ground level but below the floor level, either a course of vitrified stoneware made on purpose, or two layers of slates laid in cement, or some equally effective impervious material, the intervention of which between two courses of brickwork bars will prevent the further upward progress of the damp ...
This allows for further stabilization of sand dunes. These larger plants, along with wooden sand fences, footpaths, Dutch ladders and boardwalks help to catch windblown sand. [18] Stabilizing sand dunes with plants is a common practice and can be implemented on private and public beaches.
