Available in PDF, EPUB and Kindle. Book excerpt: Numerical simulation of surface runoff is used to understand and predict watershed sediment transport and water quality and improve management of agricultural watersheds. However, models currently available are either simplified or parameterized for efficiency. In this chapter, CCHE2D, a physically based hydrodynamic model for general free surface flow hydrodynamics, was applied to study watershed surface runoff and channel flows. Multiple analytical solutions and experimental data were used to verify and validate this finite element model systematically with good results. A numerical scheme for correcting the bilinear interpolation of the water surface elevation solutions from the cell centers to the computational nodes was developed to improve the model. The correction was found necessary and effective for the sheet runoff simulations over the irregular bed topography. The modified numerical model was then used to simulate storms in a low-relief agricultural watershed in the Mississippi River alluvial plain. This physically based model identified the channel networks, watershed boundary automatically, and helped to develop rating curves at the gage station of this complex watershed. The numerical simulations resolved detailed runoff and turbulent channel flows, which can be used for soil erosion and gully development analyses.

Available in PDF, EPUB and Kindle. Book excerpt: Runoff plays an important role in the agricultural and urbanized environments. Surface runoff is determined primarily by the amount of precipitation and by infiltration characteristics related to soil type, soil moisture, antecedent rainfall, land cover type, impervious surfaces, and surface retention. In this study, CCHE2D, a numerical model for free surface flow hydrodynamics, is applied to study the rain induced runoff and channel flow mixed problems. The main goal of this study is to incorporate rainfall as an input into the existing free surface flow model, CCHE2D; to verify and validate the CCHE2D model’s runoff simulation capability using analytical solutions and experimental data so that the model is proven to be accurate and capable of simulating rainfall induced flow and runoff; and to simulate runoff process in complex watershed using high resolution data such as LiDAR topography to validate that the model can be applicable to problems with a variety of spatial scales and complexity. Infiltration and subsurface flow is not considered throughout the study. The model’s capability of simulating the rainfall generated runoff processes is tested using analytical solutions, experimental data and field data. Comparison of numerical solutions with both analytic solutions and observed overland flows resulting from unsteady rainfalls is satisfactory. To validate the applicability of the shallow water model CCHE2D, research has been conducted using very high resolution LiDAR data in a small real world agricultural watershed in northwestern Mississippi, USA, in the Mississippi River Alluvial Plain known as the Mississippi Delta. The fine resolution of the numerical simulations resolved detailed runoff patterns in watersheds. This capability can be used for soil erosion and agro-pollutant transport and flood impact studies.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the results of several years of experimental work - much of it never before published - in drainage basin evolution, hydrology, river-channel morphology and sedimentology. These investigations are related to real-world applications, particularly geological exploration and mapping. The book shows how awareness of natural phenomena can improve management of the natural environment, such as the control of rivers and eroding gullies.

This book was released on 2014-06-23 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical model for simulation of surface-water integrated flow and transport in two (horizontal-space) dimensions is documented. The model solves vertically integrated forms of the equations of mass and momentum conservation and solute transport equations for heat, salt, and constituent fluxes. An equation of state for salt balance directly couples solution of the hydrodynamic and transport equations to account for the horizontal density gradient effects of salt concentrations on flow.

Book excerpt: Rivers form one of the lifelines in our society by providing essential services such as availability of fresh water, navigation, energy, ecosystem services, and flood conveyance. Because of this essential role, mankind has interfered continuously in order to benefit most and at the same time avoid adverse consequences such as flood risk and droughts. This has resulted in often highly engineered rivers with a narrow set of functions. In the last decades rivers are increasingly considered in a more holistic manner as a system with a multitude of interdependent processes. River research and engineering has therefore added to the river fundamentals also themes like ecohydraulics, consequences of climate change, and urbanisation. River Flow 2020 contains the contributions presented at the 10th conference on Fluvial Hydraulics, River Flow 2020, organised under the auspices of the Committee on Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). What should have been a lively physical gathering of researchers, students and practitioners, was converted into an online event as the COVID-19 pandemic hindered international travelling and large gatherings of people. Nevertheless, the fluvial hydraulics community showed their interest and to be very much alive with a high number of participations for such event. Since its first edition in 2002, in Louvain-la-Neuve, this series of conferences has found a large and loyal audience in the river research and engineering community while being also attractive to the new researchers and young professionals. This is highlighted by the large number of contributions applying for the Coleman award for young researchers, and also by the number of applications and attendants to the Master Classes which are aimed at young researchers and students. River Flow 2020 aims to provide an updated overview of the ongoing research in this wide range of topics, and contains five major themes which are focus of research in the fluvial environment: river fundamentals, the digital river, the healthy river, extreme events and rivers under pressure. Other highlights of River Flow 2020 include the substantial number of interdisciplinary subthemes and sessions of special interest. The contributions will therefore be of interest to academics in hydraulics, hydrology and environmental engineering as well as practitioners that would like to be updated about the newest findings and hot themes in river research and engineering.
