The lack of vegetation also does not act as a sieve to capture the soil. Muddy water also created an environment where the water temperature increases killing any micro organisms that feed at the river bed. Faster movement of water also creates deeper channels and creates wider rivers during storms. (Sotir, 1998) Excessive run off and soil are creating downstream flooding conditions that have been unprecedented when compared to the past. Homes and businesses have been significantly impacted by the new problem as insurance rates and the cost of maintaining a house or business is also on the rise.
Birds and animals that depend on the river's ecosystem are also impacted by the new stream flow and quality of water. Excessive silting of rivers might cause flooding in traditional nesting locations of migratory birds. Often, birds select these locations for life and then lose generations of chicks due to flooding. Contamination in the soil as a result of fertilization upstream also creates toxic levels higher than expected. Wildlife that survives on dependent organisms tends to get affected as well. Phosphorous which is used as a growth aid for land plants also does the same for aquatic plants. Algal blooms in lakes and rivers further deplete the oxygen levels in the water.
The unchecked soil is also creating havoc with ports. Most significant ports are located at or near the mouth of the rivers and the soil often get deposited at these locations. Dredging of ports is often a necessity to maintain the depth of the port to allow larger vessels to enter the port. It is observed that better engineering upstream of dams and reservoirs can help reduce the problems down stream. (ScienceDaily, 2008) Many tests have been undertaken to find out conditions that work the best. Amongst the most significant observations were the compacting of soil and controlling the gradient of the water flow.
Experts in the field, scientists and members of the local populations are all realizing the direct and the indirect impacts of soil erosion. Many costs can be directly measured as in the increase of insurance on home close to sea, along rivers and cliffs and the reduction of...
Rainfall Simulation Studies to Estimate Soil Erosion as Influenced by Rainfall Intensity and Slope in Four Distinct Soils (1) To investigate the effect of slope angle and rainfall intensities on soil erosion under controlled conditions using four (4) distinct soil types; (2) To compare this data with that for a cropped plot; and (3) To highlight an approach at estimating erosion risk and nutrient loss. Soil erosion or the wearing away of
Clay and materials similar are more readily subject to the environmental and atmospheric meteorological conditions that can impact the sustainability of a clay-based foundation. Another problem that can cause problems for a foundation subject to weak soil characteristics is "subsidence" (Shabha, Kuhwald, 1995). According to Shabha & Kuhwald (1995), "Subsidence can be defined as a downward movement or a soil on which buildings stand from causes unconnected with loading from
Weathering and erosion are similar processes that occur over time, impacting the nature and appearance of landscapes. The two processes both affect rocks. Erosion is defined by the movement of air, water, or ice on rock formations, or on the force of gravity on rocks as in landslides. On the other hand, weathering simply breaks down or even chemically changes the composition of rocks without necessarily moving them. Weathering and
Rural poverty is a concerning matter in many areas mainly because farmers there have had access to limited education concerning attitudes they need to employ in order to be successful in their field of work. Conserving soil is not only beneficial for the environment, as it also plays an important role in helping individuals in rural areas. "Reducing land degradation is more likely to be achieved by supporting NGOs that
lowland Maya decimation is much more than at any time before, and there are currently several studies that concentrate on the period from roughly A.D. 750 to A.D.1050. Previously, researchers have had a tendency to sum up clarifications of the decimation from individual locales and areas to the marshes in totality. Later methodologies push the extraordinary differences of changes that took place over the swamps amid the Terminal Classic
Agriculture practices have significant impact on both marine and terrestrial environment. All over the world many agriculture practices are creating negative impact on tropical forest and on wild life. This study shows the negative impacts of banana, coffee and pineapple plantation on the marine and terrestrial environment in Costa Rica. Many agriculture practices are creating negative impact on the tropical rainforest. This study also describes the issue of mono culture
