An ESTUARY that shows a small to moderate salinity change with DEPTH

اختلاط در دهانه رودخانه

مصب رودخانه که تغییرات آرام شوری با عمق را نشان می‌دهد 

In dealing with sediments and sedimentary rocks it is necessary that precise dimensions should be applied to such terms as CLAY, sand, pebble, etc. Numerous scales have been suggested, but in this work, the Wentworth-Udden scale is used, as it is widely accepted as an international standard. In the table which follows, particle size limits are shown, but within most groups further subdivision is possible; for example, sand may be described as very fine, medium, coarse, very coarse. particle size is normally determined by hand measurement of pebbles, cobbles, and BOULDERS, sieving of GRAVEL, sand and silt and ELUTRIATION of silt and CLAY

اندازه ذره-دانه‌بندی

تقسیم‌بندی رسوبات و دانه‌ها بر اساس اندازه آنها

The wave period determined by the inverse of the frequency at which the wave energy spectrum reaches its maximum

دوره اوج

پریود حداکثر موج

Beach material usually well-rounded and between about 4 mm to 64 mm diameter

ریگ-سنگریزه

مصالح ساحلی دایره‌ای شکل که بین 4 تا 64 میلی‌متر قطر آن‌ها می‌باشد

An elongated portion of land nearly surrounded by water and connected to a larger body of land, usually by a NECK or an ISTHMUS

شبه جزیره یا تنگه خاکی

یک بخش کشیده شده از خشکی که توسط آب احاطه شده است و از طریق یک باریکه به خشکی بزرگتر متصل می‌شوند

Due to the effect of the tides; such CURRENTS may be rotating rather than having a simple back and forth motion. The CURRENTS accompanying tides are known as TIDAL CURRENTS

متناوب

ناشی از اثر کشندها؛ چنین جریان‌هایی ممکن است بیشتر از یک جریان بازگشتی معمولی چرخش داشته باشند

constitute a part of the general ocean circulation. The term DRIFT CURRENT is often applied to a slow broad movement of the oceanic water

 پایدار و یا اقیانوسی

بخشی از چرخش کلی اقیانوس

The zone extending downward from the ocean surface within which the light is sufficient to sustain photosynthesis. The DEPTH of this layer varies with water clarity, time of year and cloud cover, but is about 100 m in the open ocean. It may be considered the DEPTH to which all light is filtered out except for about one percent and may be calculated as about two and one-half times the DEPTH of a SECCHI DISK reading

ناحیه فتوسنتز

منطقه‌ای در زیر اقیانوس که نور خورشید می‌تواند درآن وارد شود و فتوسنتز در آن رخ می‌دهد (تقریباً 100متر زیر سطح دریا)

A structure, usually of open construction, extending out into the water from the shore, to serve as a landing place, recreational facility, etc., rather than to afford coastal protection

اسکله-موج شکن

سازه روبازی که از ساحل به  داخل آب گسترده شده است

 EROSION of closed flow CHANNELS (tunnels) by the passage of water through soil; flow underneath structures, carrying subsoil particles, may endanger the stability of the structure

رگاب

فرسایش بواسطه عبور آب داخل خاک

An element of surface resulting from subdividing an image into the smallest identically shaped figures that give information about the location, intensity and perhaps color of the source, but such that no smaller subdivision will provide more information

پیکسل-جزئ تصویری

کوچک‌ترین جزء یک تصویر که موقعیت و رنگ قسمتی از تصویر را مشخص می‌کند

(1) (Geographical) an elevated plain, tableland or flat-topped region of considerable extent. (2) (Oceanographical) an ELEVATION from the bottom of the ocean with a more or less flat top and steep sides

فلات-جلگه مرتفع

(1) For a PLUNGING WAVE, the point at which the wave curls over and breaks. (2) The final breaking point of the waves just before the water rushes up the BEACH

نقطه شکست –نقطه پلانژِی

برای یک موج شیرجه‌ای نقطه‌ای که درآن موج  می‌چرخد و می‌شکند

A crest curls over air pocket; breaking is usually with a crash. Smooth splash-up usually follows

شیرجه‌ای

خمیدگی‌های تاج روی بسته‌ی هوا؛ شکست عموماً با یک درهم شکستن همراه است. معمولاً صدای چلب و چلوب  دلنوازی در ادامه‌ی آن می‌آید

A BEACH, usually small, between two headlands

 دریا کنار انبانه ای

ساحل کوچکی بین دو دماغه

(1) The extreme end of a CAPE, or the outer end of any land area protruding into the water, usually less prominent than a CAPE. (2) (SMP) A low profile SHORELINE PROMONTORY of more or less triangular shape, the top of which extends SEAWARD
