This winter, extreme flooding and erosion may be on the way for B.C’.s coastal communities.
A new study says El Nino and La Nina will have an impact on the province this winter.
UVic geography professer Ian Walker is co-author of the study, published in Nature Geoscience today.
“It’s not just El Nino we should be concerned about,” says Ian Walker, UVic geography professor and co-author of the study. “Our research shows that severe coastal erosion and flooding can occur along the BC coast during both El Niæo and La Nina storm seasons, unlike further south in California. We need to prepare not only for this winter, but also for what could follow when La Niæa comes.”
Walker is the co-author of the study and also says infrastructure needs upgrading.
“Critical infrastructure and coastal development is in low lying, flood prone areas. A lot of this infrastructure needs serious upgrading. As we begin to do that we need to start preparing for and understanding that climate variability, whether it’s El Nino or coastal storms, is part of the picture that we should be planning for.”
Due to our coastal location, we could face increased storm surges and erosion.
Typically, impacts from El Nino are experiencedd mot during the late fall through early spring months.
