Spatially Varied Flow Profiles in a V-Shaped Side-Channel

Boundary shear stress in spatially varied flow with increasing discharge

The distribution of the wall shear stress on the bed and sidewalls of an open channel receiving lateral inflow was obtained from experimental measurements of the distribution of the velocity in the viscous sublayer using a laser doppler velocimeter. The experiments were conducted in a 0.4 m wide by 7.5 m long flume. Lateral inflow was provided into the channel from above via sets of nozzles pos...

instability in a spatially periodic open flow

Laboratory experiments and numerical computations are conducted for plane channel flow with a streamwise-periodic array of cylinders. Well-ordered, globally stable flow states emerge from primary and secondary instabilities, in contrast with other wall-bounded shear flows, where instability generally leads directly to turbulence. A two-dimensional flow resembling TolhnienSchlichting waves arise...

Educational Investments in a Spatially Varied Economy

This paper presents a simple two-period, dual economy model in which migration options may affect the informal financing of educational investments. When credit contracts are universally available and perfectly enforceable, spatially varied returns to human capital have no effect on educational investment patterns. But when financial markets are incomplete and informal mechanisms subject to imp...

Spatially varied soil erosion under different climates

The spatial variability of the factors of the universal soil loss equation is examined on the mediterranean basin of Conca de Tremp covering 43.1 km in Spain. The evaluation of the rainfall erosivity R and the soil erodibility K is relatively straightforward and spatially-averaged values of these parameters can be applied to the entire basin. Conversely, the spatial variability of annual soil e...
