Desert Landforms

Desert topography We were taken to a desert area about 20 kilometers away from the backdrop of Jeddah. When arriving, we are asked to conduct a physical investigation of the landscape and landscape of the nearby area and to find evidence of the river process and the resulting landscape such as erosion, traffic, weathering and sedimentation It was. These surveys were conducted in the valley between the dry season ("Wadi Valley") which is an intermittent waterway. In order to carry out our measurements we previously designed the following equipment: * Tiltmeter and its cross section (long profile) to measure the gradient along "dry river".

Ecological landscape known as desert, which is defined by very dry low precipitation and high evaporation conditions, includes rich mountains, plains, plateaus and canyons including unique desert topography variants. These include gravel plains, sand dunes, dry lake bottom and so on. Many natural factors, especially current and past climatic conditions, contribute to the formation of the desert. California's Mojave Desert consists of 1.6 million acres of landscapes that have undergone millions of years of change, including mountains, valleys, volcanic areas and dry lake basins. This area is in a huge inland basin, ancient lakes flow into adjacent valleys and finally flow into Death Valley. After being depleted in the area, it exposes the dry lake bottom to wind erosion

Plains are the most prominent topography in the desert. In the basin surrounding mountains and hills, the drainage path faces the center of the basin and as the sediments at the edge of the basin gradually accumulate, a nearly flat plain forms in the center of the basin. In the case of sufficient water, the plain is covered with shallow water. Such shallow lakes are called games. The plain of plaque covered with salt is called an alkali surface. Weathered mantle from rock and naked soil is blown off by continuous wind movement in one direction. This process can result in shallow depression called deflationary depression. The surface of the rock is subject to shock and wear of sand and sand, creating the first shallow indentation called blowout.
