The Bradshaw model aims to show how different characteristics of a river change from the source to the mouth in a simplistic method that can easily be understood (greenfield geography‚ 2012). A geographical model is “an attempt to understand natures is high complexity. Therefore geographers try to develop simplified models of it” (Waugh‚ D. 2009). The model shows a series of triangles and each one represents a different fluvial characteristic. On the left is the source and on the right is the mouth

urban settlements. To cope with urbanization within a drainage basin‚ urban development and deforestation are carried out‚ which affect flows to and within a river channel. Other factors like drainage density‚ climate‚ area of drainage basin and gradient of slope can also affect flows to and within a river channel. Flows to and within a river channel also include overland flow‚ infiltration‚ through flow and base flow. Overland flow is the movement of rainwater over land. It occurs when either the

In particular my report will focus on 3 sub questions; 1. How does the cross-sectional area of the river Caerfanell change with distance downstream? 2. How does the velocity change with distance downstream? 3. How does channel efficiency change with distance downstream? Figure 1: Bradshaw Model shows the changes of river from Upstream

Besides that‚ the damped rivers also being made as one of the destination for tourism like Tasik Kenyir in Terengganu. The process of constructing the reservoir is being made by damping of a river. We always think that these reservoirs will give us a lot of benefit‚ but how about the negative effect of the existence of this reservoir? Do you know that the construction

reminder of life. In ancient complex river societies water provided a beginning and advancement opportunity in agriculture in that it cared for plants‚ provided for animals‚ replenished drinking water‚ and was a beacon for trade and vocation. One main use of water was providing fertile silt and fresh water for agriculture and planting necessary fruits and vegetables. Due to the excessive flooding and heavy rain falls that were common to the complex river societies in ancient Egypt‚ Asia‚ and

sediment release in a dam removal project anywhere in the world. Because of the amount of sediment behind large dams like the Elwha‚ the demolition must be done gradually over time to ensure that there is not an overflow of sediment rushed down the river which could cause significant damage to the landscape and the organisms which inhabit it. At the time of the dam removal the Elwha was holding behind it 15‚000‚000 cubic yards of silt. Sediment buildup isn’t the only thing that dams can change about

While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt‚ these changes in size are unlikely to be considered significant unless they flood property or drown domestic animals.
