Irreversibility in river flow

Wilsonian vs. 1pi Renomalization Group Flow Irreversibility

We present a line of reasoning based on the analysis of scale variations of the Wilsonian partition function and the trace of the stress tensor in a curved manifold which results in a statement of irreversibility of Wilsonian renormalization group flow for unitary theories. We also analyze subtleties related to subtractions in the case of the 1PI effective action flow. e-mail: [email protected]...

River Flow

This chapter presents a range of key concepts that enable natural rivers to be understood as complex flows of water and sediment that interact and often result in changes to the channel shape. The implications for salmon fisheries and invertebrates are also considered. Rivers are linear features and so it might be supposed that the flow hydraulics would be unidirectional and relatively simple t...

River Flow Simulation Using SWAT Physically Based Model in Barandouzchay of Urmia Lake River Basin

Nowadays, there are too many models in the world for simulation of hydrological processes, such as the SWAT physically based model. The SWAT model is a continuous and physically based hydrologic model that is the smallest unit in this model is Hydrologic Response Unit, and all hydrological processes are simulated in each of these units. This model can simulate runoff, sedimentation, erosion and...
