The main impacts on the wetlands in the area are associated with historic land use. They include drainage channels and furrows that modify wetland hydrology and reduce their functionality. Eight wetlands in the area were identified for rehabilitation intervention. Concrete and gabion structures are used to stabilize erosion and help to maintain wetland health. The wetland

RETAINING WALLS AND REINFORCED SOIL SLOPES Retaining walls and reinforced soil slopes are used in areas where free-standing (natural) earth slopes are undesirable‚ usually because of space restrictions. These walls have‚ in the past‚ normally been poured reinforced concrete (gravity or cantilever)‚ timber‚ steel‚ or precast concrete cribbing‚ stone-filled wire-basket gabions‚ timber or steel sheeting‚ or steel soldier pile and lagging walls‚ all of which provide external support to the

One of the most unique factors of Death Valley is its thoroughly different geological characteristics. There is volcanic activity‚ occurrences of erosion and deposition‚ as well as interesting types of landforms‚ minerals and rocks that all makes up Death Valley’s complicated‚ but interesting geological history and features. The current aspect of the geology of Death Valley as well as the shape of its future is all but dull‚ but how did Death Valley get this‚ both intriguing and beautiful‚ landscape

1207‚ Bangladesh ABSTRACT: Bangladesh is likely to be one of the most vulnerable countries in the world to climate change. This paper discusses the possible impacts of climate change in Bangladesh through tropical cyclones‚ storm surges‚ coastal erosion and back water effect. The possible increase in cyclone frequency in the Bay of Bengal‚ lying south of Bangladesh‚ due to climate change is looked at by analyzing the cyclone data for 119 yr. Both qualitative and quantitative discussions are made

1-Drainage system- A drainage system is the pattern formed by the streams‚ rivers‚ and lakes in a particular drainage basin. They are governed by the topography of the land‚ whether a particular region is dominated by hard or soft rocks‚ and the gradient of the land. 2-Drainage basin-A drainage basin is an extent or an area of land where surface water from rain and melting snow or ice converges to a single point‚ usually the exit of the basin‚ where the waters join another waterbody‚ such as a

types of sand found on Hawaiian beaches are black‚ green‚ red‚ and white sand. They are all different in their compositions because of the ways that they were formed. For example‚ the black sand is from lava or the erosion of black volcanic rocks‚ and the red sand is formed from the erosion of a cinder cone. 16.
