![]() ![]() “The combination of climate change and development pressures has the potential to significantly increase the effects of flooding and erosion on coastal populations,” Ruggiero said. The model considered the effects of continuing current development policies, implementing only policies designed to combat environmental changes, realigning policies to be more consistent with a changing environment, and relaxing current policies such that development takes precedence over protecting coastal resources, beach access and everything else. Those measures include the construction of protective structures between the beach face and the shoreline adding sediment to beaches where access in front of those structures has been lost removing or relocating buildings repeatedly affected by coastal hazards and turning hazard zones into conservation areas constructing new buildings well above the base flood elevation established by the Federal Emergency Management Agency and preventing new development in hazard zones even if those areas are within urban/community growth boundaries. In a set of analyses involving many variables, the most important takeaway is the power of policy measures to positively or negatively affect a coastal community’s climate risk level, Ruggiero said. Using data from Tillamook County along the northern Oregon coast, the researchers plugged into Envision information on landscape characteristics, population growth, development, water level, coastal change models, policy narratives and climate change scenarios. Professor Peter Ruggiero of OSU’s College of Earth, Ocean, and Atmospheric Sciences and John Bolte, chair of OSU’s Biological and Ecological Engineering program, led the study, which employed a modeling platform known as Envision to quantify the expected effects of flooding and erosion on buildings and infrastructure as well as beach accessibility through the remainder of the 21 st century. The findings, published in the journal Water, provide an important framework for managing the interactions between human-made and natural systems in cities and towns along shorelines as the Earth continues to warm, the researchers said. – Coastal communities face increasing danger from rising water and storms, but the level of risk will be more closely tied to policy decisions regarding development than the varying conditions associated with climate change, new research by Oregon State University suggests. Notes:Before using this Flood Map application, please note that for various technical or non technical reasons the application is not guaranteed free of bugs or inaccuracies. Negative elevation means depth below sea level.ĭata Sources: Mazpzen, TNM, SRTM, GMTED, ETOPO1 The elevation layered on the map is in meters and is from sea level. By setting negative elevation, Bathymetry study is also possible.We also think that it can help in planning irrigation system and water management. ![]() It can help to perform elevation analysis of an area for any purpose like city/town planning, new construction etc.Global Warmin and Sea Levele Rise are the effects of Climate Change.Effect of sea level rise or sea level change can be seen on the map.It can also provide floodplain map and floodline map for streams and rivers.Corvallis, US Flood Map can help to locate places at higher levels to escape from floods or in flood rescue/flood relief operation.Corvallis, US Flood Map may help to provide flood alert/flood warning if flood water level at certain point is rising.Corvallis, US Flood Map may be useful to some extent for flood risk assessment or in flood management, flood control etc. ![]()
