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...

Based on a digital elevation model (DEM) and GIS technology, we extracted analyzed stream geomorphic indices—such as the slope, relief degree of land surface (RDLS), hypsometric integral (HI) channel steepness index (ksn)—of Cangshan Piedmont Fault, Fengyi–Dingxiling Fault Midu Basin Margin in northern segment Red River Zone. This work indicates that all indices show higher values, with highest...

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...

Morphotectonic investigations were carried out by the use of morphometric indices which serve as a tool of identification in regions with active tectonic warp. Landforms in active deformation area are produced from relations of tectonic and surficial processes. One of the most significant landforms underground is rivers that are extremely responsive to tectonic movements mainly uplift and tilti...

The Gulf of Suez area represents one the most famous tectonic structures in Red Sea, with a long history low-, moderate-, and high-intensity earthquakes. This paper provides geomorphic analytics fault-initiated mountain front sinuosity (Smf) stream gradients that cross various segments fault scarps. results from index valley floor width to height ratio (Vf) suggest different levels activities a...

Abstract Rock landslides are generally controlled by a series of discontinuous interfaces formed damage to complex structural rock masses that is related folds, faults, and shear zones, which provide potential failure boundaries. Based on detailed case study, the authors illustrate not only affects 3D boundaries but also significantly controls initiation mode. In this paper, six large triggered...
