Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...

Curved channels and aquatic vegetation are commonly present in the riverine environment. In this study, effects of density distribution on hydrodynamic characteristics a mixed layer developed over 180-degree curved channel were investigated through flume experiments. Wooden sticks used to simulate rigid distributed along half side channel, 200 Hz acoustic Doppler velocimeter (ADV) was employed ...

The paper discusses the application of a chain mathematical models for calculating glacial debris flow. Modeling was carried out Bodomdara River valley case an outburst Lower Lake (Gorno-Badakhshan Autonomous Region, Tajikistan). FLOVI program, written in Python programming language, applied; it combines equations lake hydrograph and characteristics flow during its formation. To calculate flood...

Present study examines turbulent structures of a rough bed open-channel flow in the context of deterministic approach. Instantaneous velocity field is measured in different hydraulic conditions using two dimensional Particle Image Velocimetry (PIV) in vertical plane and Stereoscopic PIV in horizontal plane. Different techniques and quantities such as swirl strength, two-point and cross-correlat...

The effectiveness of three simple flood operating rules in reducing the peak flow is compared for four simplified hydrograph shapes. The Minimize Flood Peak rule uses available flood storage capacity to store peak flows from an accurate hydrograph forecast. The less demanding Minimize Flooding Frequency operating rule releases water at or below channel capacity until the flood storage pool is f...

Separating surface flow (SF) from subsurface (SSF) based on direct runoff measurements in river gauges is an important issue hydrology. In this study, we developed a simple and practical method, coefficient (RC), for separating SF SSF. RC depends mainly soil texture, land use cover, but also considered the effect of slope rainfall intensity. We assessed our RC-based method three different types...

In the current study, five different atomistic water models (AWMs) are implemented, In order to investigate the impact of AWMs treatment on the water velocity profile and density number. For this purpose, Molecular dynamics simulation (MDS) of Poiseuille flow in a nano-channel is conducted. Considered AWMs are SPC/E, TIP3P, TIP4P, TIP4PFQ and TIP5P. To assessment of the ability of each model in...

Abstract. The distributed unit hydrograph (DUH) method has been widely used for flow routing in a watershed because it adequately characterizes the underlying surface characteristics and varying rainfall intensity. Fundamental to calculation of DUH is velocity. However, currently velocity formula assumes global equilibrium ignores impact time-varying soil moisture content on velocity, which thu...
