Ecologically-based Management Factors and criteria of River-Valleys in Tehran metropolis-Case Study: River-Valleys of Kan
Iran has seasonal rivers because of dry climate, low rainfall and different topography. These river- valleys have main role in forming, genesis, and sustainability of human settlements and provide different ecological services. The main services include beauty, store of green spaces, water supply, reduce and create temperature differences, local air flow and natural ventilation which are part o...
متن کاملThe Formation of Martian River Valleys by Impacts
We explore the role of large impacts in creating the Martian valley networks. Recent dating shows that some large impact basins are contemporaneous with the valley networks. The mass deposited (and volatiles released) by impacts is large, and comparable with the mass from the Tharsis volcanic construct. Steam atmospheres formed after large impacts can produce more than 600 m of rainfall, follow...
متن کاملPresenting a Geomorphological Conceptual Model of Construction of bridges in urban floodway- river valleys
Geomorphology is related to the shapes and processes of the earthchr('39')s surface, and any human activity, including planning, that changes the shape of the earth and can cause quantitative and qualitative changes in the movement and movement of materials and kinetic energy and affect the geomorphic system. The attention and involvement of geomorphologists are included. Geomorphology, as a s...

15 صفحه اولFormation of Fluvial Hanging Valleys: Theory and Simulation
Although only recently recognized, hanging tributary valleys in non-glacial landscapes are not uncommon in tectonically active regions. Standard river incision models do not allow for the formation of fluvial hanging valleys; these disequilibrium landforms present an opportunity to advance our understanding of river incision processes. In this work, we demonstrate that thresholds apparent in se...
