Anzali Wetland and morphological characteristics of the impact of changesin land use

Caspian basin after being removed from the open seas or lakes in Pliocene time, money andsince then a series of tectonic activity, fluctuating water levels, the effect of waves andcurrents of the river morphology and current as it created. Sediments along the shoreline toerosion and sedimentation caused severe changes in morphology are Anzali wetland.Morphological forms based on the manufacturer and type deposits occur in differentenvironments. Recognizing symptoms and morphological changes that could be a pivotal rolein coastal planning and coastal management have. Swamps and wetlands, Delta, tab, sand,sandy zones, sand dunes, marine terraces and flood plains, mud zones, alluvial Fans,landscape morphology are observed in different parts of the Caspian Sea and Anzali Wetland.Current status of the beach about 10 thousand years ago with the general trend of lowering thewater levels is. In recent decades, human factors, the coast is one of the basic parameters ofthe deformation. Margin morphology can identify shifts in the development and landuseplanning coastlines, coastal areas to be effective. In this research, studies, documents andsoftware using Ilwis, Autocad and photoshop and aerial photographs, geological maps,topographic1/ 20000 and 1/50000 and a method based on RS and GIS methods to separatethe units in the sedimentary environment they have been marked And the resulting changes inthe rate of water level changes and coastal morphology and sedimentary units, replacement ofthe final maps will be prepared. Anzali wetland in coastal sediments of the tab is made up ofcoastal and coastal barriers. Anzali lagoon behind the beach is one of the lakes that were oncepart of the Caspian Sea coastal waters. Anzali wetland in the past had a large spread butgradually by alluvial sediments - Sefidrood deltaic branches and rivers of Rasht region, Masaland Fouman is filled. Anzali indentation tectonics is derived from the Caspian Sea backwardsomewhat isolated from the sea and sand with a blade (the area between Anzali andKapurchal) is formed. Facies of Pleistocene marine and coastal areas indicates the presence ofPleistocene Sea coast at the foot of the Alborz. Gradually with the gradual retreat of the seaand tectonic activity has increased the extent of the coastal plain. Coastal facies, especiallyalong the asphalt road protrusion City - Friday Market (Friday Market on the northern sidereached a three-way road) that is visible is located in the south of Anzali wetland.
