Prestressed concrete pipe piles have been increasingly used as deep foundation structures for decades. Despite the availability of a limited number of well-instrumented load test results, pile designers would like to know the general performance of such piles in case of lacking adequate experience. An attempt is made in this study to establish a database composed of more than one thousand of pile tests. All piles are founded in silty soil that is one of the competent bearing geomaterials. Short and medium-length piles with slenderness ratios ranging from 20 to 80 are most widely used. The capacity of pile increases with increasing the pile slenderness ratio until a limiting value is achieved. Use of very long piles to reduce settlement is unfavorable and the rebound rates for piles with various lengths are similar. An independent case study is also conducted to witness the success of employing the empiricism-based analyses in the preliminary design of concrete pipe piles.

Land managers are currently faced with a nexus of challenges, both ecological and social, when trying to govern natural open spaces. While social media has led to many challenges for effective land management and governance, the technology has the potential to support key activities related to habitat restoration, awareness-raising for policy changes, and increased community resilience as the impacts of increased use and climate change become more apparent. Through the use of a case study examining the work of the Central Arizona Conservation Alliance’s social media ambassadorship and its app-supported community science projects, we examine the potential and realized positive impact that technology such as social media and smartphone apps can create for land managers and surrounding communities.
