Changes in the physical structure of urban streams can occur abruptly due to flashy high-flow events and subsequently alter stream processes, including transient storage and nitrate uptake. We examined temporal variability in transient storage and nitrate uptake by exploring the effects of altered physical characteristics resulting from a single high-flow event in three reaches of Spring Creek,...

Networks of marine protected areas (MPAs) are being adopted globally to protect ecosystems and supplement fisheries management. The state of California recently implemented a coast-wide network of MPAs, a statewide seafloor mapping program, and ecological characterizations of species and ecosystems targeted for protection by the network. The main goals of this study were to use these data to ev...

Kuhbanan fault system, as one of the intracontinental faults of central Iran, is recognized by considerable seismogenic activities and modern morphotectonics evidences with a strike-slip (reverse component) motion. According to the geometric and kinematics data, Kuhbanan fault has been divided into 5 segments (S26, S27, S28, S29, S30) in Bahabad region. Measured geomorphic indices of ratio of v...

This study includes a general description of the Earth’s karst types based on literary data and field observations. An improved classification distinguishes main group, subgroup; and, division involves type, subtype, variety, non-individual type. The relation between type area is described. role various characteristics karsts in development primary, secondary, tertiary analyzed. Their structure...

In the context of molecularly-dated phylogenies, inferences informed by ancestral habitat reconstruction can yield valuable insights into the origins of biomes, palaeoenvironments and landforms. In this paper, we use dated phylogenies of 12 plant clades from the Cape Floristic Region (CFR) in southern Africa to test hypotheses of Neogene climatic and geomorphic evolution. Our combined dataset f...

Theoretical assumptions, research methodologies and results applications of innovative geological and geomorphological mapping for landslide hazard evaluation in the alpine environment are presented in the paper. Case studies from the Italian NW-Alps highlight the role of Geomatics techniques in enhancing the accuracy of multitemporal reconstructions of geomorphic processes and landforms. Aeria...
