Abstract: The velocity distribution of turbulent pipe flow is often described by the Coles log-wake law that is a superposition of the law of the wall due to the wall shear stress and the law of the wake due to the free turbulence ...

Abstract: Baseflow separation from rainfall and streamflow data is a fundamental problem in applied hydrology, unsolved despite extensive investigations. For example, a part of baseflow is interflow, which results from rainfall ...

Abstract: This research solves Chow’s linear hydrologic systems equations thoroughly to result in a theoretical instantaneous unit hydrograph (UH), which is a superposition of many (M) negative exponential functions. This implies ...

Abstract: Unit hydrograph (UH) is widely used for predictions of flood hydrograph from a known storm. Its concept and theory are simple and straightforward, but its practical applications are cumbersome because it is discrete and ...

Abstract: It is time to shift our paradigm of small watershed design from a graphic (or tabular) to a theoretical method, because (1) the recent general unit hydrograph (UH) model can convert a design hyetograph to a design ...

Abstract: Plane Couette flow between two parallel smooth walls is one of the classic wall-bounded shear flows. Analytical description of this flow is still limited to the linear law for laminar flow, the classic law of the wall, and ...

Abstract: When a sphere impacts a granular bed such as a sand bed, the penetration depth is often determined by empirical scaling laws or numerical simulations. This paper uses a unified force law for granular impact cratering to ...

Abstract: The Shields diagram is a classic method for quantifying sand incipient motion in sediment transport. It is often expressed by empirical or semiempirical equations. This research applies the Padé approximant to the data in ...
