Mudboils In Tully Valley

Mudboils cause structural failures since they are suspensions of gravel, clay, silt and fine sand creating an unstable surface. Since the beginning of persistent mudboil activity in the 1970’s, natural landscapes and engineered features have become subject to land-subsidence as mudoils continually deteriorate the areas in their path (Tresohlavy 2003, pp. 27). Petroleum pipeline rerouting, telephone cable burials, and the collapse of bridges have demonstrated the true capabilities of mudboil persistence and destruction (Kappel & McPherson, 1998). These impacts have created a motive for truly solving the problems of mudboils within the Tully Valley. Portions of underground pipeline have become exposed due to the land subsidence issues

This parallels the process of ecological engineering as it involves designing the ecosystem to benefit humans and the environment. The only controversial aspect involves humans original presence in creating these issues (salt brining). The question arises on whether this truly does involve ecological engineering, something to be decided on a personal view and opinion. Even though this occurrence was caused in part by human influence, solving the issue needs to correlate to environmental needs along with human benefit. For example, the use of depressurizing wells creates a system of water flow that should be existent within the system, but instead is compromised by the artesian pressure underground. Customizing solutions to reverse environmental problems involves the use of human input and could re-establish natural ecosystem …show more content…
Natural disasters throughout the world can cause various effects on these pressures causing the creation of structures similar to the mudboils of Tully Valley. Globally, mudboils occur in various conditions and change the composition of their ecosystems. Earthquake activity has caused incidents of complete landfall and extended ejections of up to 250 miles (Kappel 1996, pp. 5). Also, tectonic forces have caused marine sediment deposits that create extremely high pore-water pressures along with longer lasting sand springs (Kappel 1996). Varying conditions of geologic activity are the main culprits behind these spewing sediment formations. These conditions affect not only the ecosystem, but humans within those areas. Severity of natural disasters can depend on the scale of effects exhibited within a certain area and whether human intervention has caused these occurrences. The quality of life for humans decreases as these issues become more prominent. The inconvenience of relocating presents as the only other option than to have a residence seemingly sink into the land. Quality of life varies throughout the planet, but a large determinant of this standard is the natural environment surrounding humans. Mudboils affect the quality of living for local residents, as does those who live along contaminated rivers, agricultural land, or
