Simple Method for Relating Local Stage and Remote Discharge
Publisher: American Society of Civil Engineers
Abstract: A simple method is proposed for reconstructing the discharge hydrograph at a river section where only water level is monitored and discharge is recorded at another upstream section. The method, which is based on the ...
Formulation of the Entropy Parameter Based on Hydraulic and Geometric Characteristics of River Cross Sections
Publisher: American Society of Civil Engineers
Abstract: The linear entropic relation between mean flow velocity
Accuracy of Kinematic Wave Approximation for Flood Routing. II. Unsteady Analysis
Publisher: American Society of Civil Engineers
Abstract: The applicability of the kinematic wave (KW) approximation was investigated for unsteady flow in prismatic channels. Each of the 16 cases analyzed under steady flow conditions by Moramarco et al. (2008) was now perturbed ...
Accuracy of Kinematic Wave and Diffusion Wave Approximations for Flood Routing. I: Steady Analysis
Publisher: American Society of Civil Engineers
Abstract: The applicability of the kinematic wave (KW) and diffusive wave (DW) approximations was investigated for steady flow in prismatic channels by using a second-order two-step Lax-Wendroff numerical scheme coupled with the ...
Genetic Algorithm-Based Discharge Estimation at Sites Receiving Lateral Inflows
Publisher: American Society of Civil Engineers
Abstract: The genetic algorithm (GA) technique is applied to obtain optimal parameter values of the standard rating curve model (RCM) for predicting, in real time, event-based flow discharge hydrographs at sites receiving significant ...
Estimation of Mean Velocity in Natural Channels Based on Chiu’s Velocity Distribution Equation
Publisher: American Society of Civil Engineers
Abstract: The applicability of the linear relationship between the mean and the maximum flow velocities, based on the entropy concept, was investigated using data collected during a period of 20 years for four gauged river sections ...
Analytical Solution for Channel Routing with Uniform Lateral Inflow
Publisher: American Society of Civil Engineers
Abstract: Distributed hydrologic models describe both hillslope and channel processes. The presence of a large number of hillslopes requires that flood routing through a channel network be computationally efficient and able to account ...
A New Empirical Formulation of the Areal Reduction Factor for Design Rainfalls Applied to the Umbria Region in Central Italy
Publisher: ASCE
Abstract: A reliable estimate of the areal reduction factor (ARF), useful for implementing the upscaling procedure of point rainfall information, is of crucial relevance in many hydrological applications aimed at hydraulic structures ...
Relating Local Stage and Remote Discharge with Significant Lateral Inflow
Publisher: American Society of Civil Engineers
Abstract: The development of a simple model for reconstructing the discharge hydrograph at a river site where only the stage is monitored and the discharge is recorded at another upstream section, is outlined. The model is designed ...
Multilinear Muskingum Method for Stage-Hydrograph Routing in Compound Channels
Publisher: American Society of Civil Engineers
Abstract: A multilinear stage-hydrograph routing method based on time distribution scheme is analyzed. The framework of the multilinear method is based on the Muskingum-type routing method, which is used as the linear submodel. The ...
