Shallow Landslide Risk Assessment of the Westerly Bluffs of the 7.5-minute Freeland Quadrangle, Whidbey Island, Washington

Landslides often occur on slopes rendered unstable by underlying geology, geomorphology, hydrology, weather-climate, slope modifications, or deforestation. Unfortunately, humans commonly exacerbate such unstable conditions through careless or imprudent development practices. Due to local geology, geography, and climatic conditions, Puget Sound of western Washington State is especially landslide-prone. Despite this known issue, detailed analyses of landslide risks for specific communities are few. This study aims to classify areas of high landslide risk on the westerly bluffs of the 7.5 minute Freeland quadrangle based on a combined approach: mapping using LiDAR imagery and the Landform Remote Identification Model (LRIM) to identify landslides, and implementation of the Shallow Slope Stability Model (SHALSTAB) to establish a landslide exceedance probability. The objective is to produce a risk assessment from two shallow landslide scenarios: (1) minimum bluff setback and runout and (2) maximum bluff setback and runout. A simple risk equation that takes into account the probability of hazard occurrence with physical and economic vulnerability (van Westen, 2004) was applied to both scenarios. Results indicate an possible total loss as much as $32.6b from shallow landslides, given a setback of 12 m and a runout of 235 m.

The Nicaragua Canal. Is the Assessment in line with National Environmental Law?

In 2013, the Government of Nicaragua approved the concession for a 173-mile canal to the Hong Kong Nicaragua Canal Development Investment Group. As the Western Hemisphere's second poorest nation, Nicaragua is attracted the promises of economic growth that may come as a result of the Canal Project. However, potential economic benefits may be offset by environmental and social damages that would likely occur as a result of the project. The Canal would bisect 16 watersheds, 15 protected areas, and 25 percent of Nicaragua’s rainforest, which would have high impacts on biodiversity, watershed services, and indigenous communities. In 1996, Law No. 217 was enacted to standardize the use and conservation of the environment and natural resources of Nicaragua. My research compares the Environmental and Social Impact Assessment of the Nicaragua Canal to the Environmental provisions of Law No. 217. This analysis can help understand the legal viability of the ESIA under Nicaragua environmental laws.
