Abstract. Salmon habitat is enhanced by the wide valleys and channel heterogeneity created by landslides. Earthflows, which are slow moving and fine-grained mass movements, can further potentially alter habitat by constricting valleys and sustaining delivery of debris and fine sediment. Here, we examine the influence of earthflows on salmon habitat in the Teanaway River basin, central Cascade Range, Washington. We mapped earthflows based on morphologic characteristics and relatively dated earthflow activity using a flow directional surface roughness metric called MADstd. The relative MADstd ages are supported by six radiocarbon ages, three lake sedimentation ages, and 20 cross-cutting relationships, indicating that MADstd is a useful tool to identify and relatively date earthflows, especially in heavily vegetated regions. Our age and MADstd distributions reflect a period of earthflow activity in the mid-Holocene and some sustained movement through the late Holocene that is primed by regolith production in the Pleistocene and early Holocene and triggered by a warm and wet climate during the mid-Holocene. The timing of earthflows is coincident with stabilization of salmon habitat and abundant salmon populations, indicating the fine sediment from earthflows did not negatively impact habitat. Wide valleys formed upstream of valley-constricting earthflows have added habitat zones, which may be of increased importance as climate change causes lower flows and higher temperatures in the Teanaway basin over the next century.


Welcome to the reimagined and contemporary international journal of Ekistics and the New Habitat: the problems and science of human settlements. On behalf of the international board of editors, it is with great pleasure that I welcome you to this very special edition led by Professor Dr. Derya Oktay, Professor of Architecture and Urban Design Maltepe University, Istanbul, Turkey. Professor Oktay’s Special Issue is a fitting volume of work identifying the many dimensions of contemporary and emerging habitat development pressures in Turkey. We invite scholars, students, practitioners, lay citizens, politicians and entrepreneurs to read the works of authors developed in this issue. The ideas and context of investigations contained in Turkey, Urbanism and the New Habitat are fresh, and exemplify the direction the Editorial Board seeks to reimagine Ekistics for our emerging millennia. The Editorial Board has many issues in production including, but not limited to: • India & Jugaad – The impact of innovation by the resilient Indian mind on habitat – Guest Editor Prof. Brinda Somaya. • Cities and Transport in the Mediterranean Region – Guest Editor Prof. Dr. George Giannopoulos • Saudi Vision 2030 - Habitats for Sustainable Development – Guest Editor Assist. Prof. Dr. Yenny Rahmayati • The Global Pacific: Island and Coastal Human Habitats – Guest Editor Assist. Prof. /Lecturer Dr. Ian Fookes. • Tribute to the late Panayis Psomopoulos who along with Constantinos Doxiadis, assured Ekistics remained very well regarded in over 46 countries and at all UN Habitat presentations and the majority world countries up until his passing. • Special issue on new theories and propositions in Ekistics led by a team with Prof. Dr. Ray Bromley, Catharine Nagashima and Prof. Dr. Christopher Benninger among others. • Regular Issues and new back issues previously unpublished.

This chapter analyzes of two types of social and cultural development in the context of peripheral regions. The projects analyze a library, Biblioteca España (2007-2015), and a cultural center, La Casa de La Lluvia (2013-present). The library was designed by El Equipo Mazzanti, a design firm, as part of the social urbanism policy framework that characterized the city of Medellin between 2004 to 2007. The cultural center was built by Arquitectura Expandida, a design collective that has been in operation since 2010 and whose headquarters is located in the city of Bogota. This analysis is unique in how it applies a sociological analysis to two architectural projects. It also seeks to demonstrate how two cultural models of habitat development that seem to be incompatible, in regard to their design and implementation, share a common goal: attain the social wellbeing of the communities living in peripheral regions.
