Rivers have energy this means that they can do work.Write down 3 works that rivers do. 1. Erosion 2. Transport 3. Deposition Attrition : Material being carried by a a river becoming rounder and smaller as they constantly collide with each other.

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

The administration also began to educate farmers on soil conservation and anti-erosion techniques‚ including crop rotation‚ strip farming‚contour plowing‚ terracing‚ and other improved farming practices. In 1937‚ the federal government began an aggressive campaign to encourage farmers in the Dust Bowl to adopt planting and plowing methods

The river erosion processes involved in the formation of waterfalls are hydraulic action‚ abrasion and solution. Hydraulic action is the force of moving water on the land. Fast flowing water forces out looses rock and soil from the river bed and bank. Soft rock is eroded faster than hard rock (differential erosion) and overtime the bank will collapse. Abrasion is the wearing away of the river bed by its load. Stones carried by the river smooth the river channel deepening & widening it. Solution

Introduction Cabbage tree creek and its catchment runs from the foothills of Ferny Hills to Sandgate and terminates at Shorncliffe before emptying into Moreton Bay. Cabbage tree creek is known for its intact riparian and the high percentage native vegetation that lines the creek. . Cabbage tree creek is well looked after by its community‚ and is considered to be very healthy‚ with a high rating for Abiotic and biotic indicators; although it has its a few low quality zones e.g. the waterway under

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

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
