Damming the Nation: How Engineers Transformed Rivers into Water Tanks for Modern South Korea
… more than a dozen large multi-purpose dams on rivers in the nation. The prevailing Korean narrative tends to regard the surge of large dam-building as the outcome of modern state authority. Rather than granting all agency to the state, this dissertation shifts focus to newly emerged water …

Inference of River Hydrodynamics and Ice Processes from Close-Range Remote Sensing
… and data collection in earth sciences and river engineering has transformed our understanding of river processes, leading to improved management and preservation of these vital resources. Remote sensing, particularly close-range remote sensing, has emerged as a useful tool for acquiring …

Estimating Flow Through Rock Weirs
… of large loose rock commonly found in ecological engineering design. By appearing more natural than concrete structures, rock weirs are preferred for use as hydraulic control structures in river engineering, stormwater management, and constructed wetlands. Rock weirs increase hydraulic head …

Quantifying the contribution of bank storage due to an alteration in stream stage
The desire to control rivers to reduce risks of flooding while providing water storage for municipal and agricultural uses has resulted in the disconnection of rivers from their floodplains. An important and often neglected outcome of this detachment is the loss of a plethora of important ecosystem …

Evaluation of hydraulic roughness routines and properties in the presence of vegetation
… needed in order to address the needs of modern river engineering. To this end, the objectives of this research were: (1) to evaluate methods for determining hydraulic roughness within open channels in the presence of vegetation, and (2) to advance understanding of the influence of vegetation on …

A study of aspects of the biology and distribution of freshwater crayfish in the Thames catchment
… have been made. The specific influences of river engineering works on populations of A. pallipes have been studied in more detail. Data concerning A. pallipes at the population level has been obtained by sampling a single lacustrine population. A comparison has been made with crayfish from a …

The effect of dikes on water surfaces in a mobile bed
… also referred to as groynes, have been used on rivers in both the U.S. and abroad to solve river engineering problems dating back to the nineteenth century. They are the prominent tool used to maintain navigation depths and prevent bank erosion on many major rivers in the world. A dike is …

Interaction of Clay Wash Load With Gravel Beds
… of wash load particles with gravel bed rivers. The effects of excess fine sediment loading to streams on general water quality, contaminant transport, and benthic organism mortality has been well examined. A fundamental assumption in fluvial geomorphology and river engineering is that …

Geomorphic Equations and Methods for Natural Channel Design
Natural channel design in river engineering is the philosophy and practice of designing stream channels by copying or mimicking the geomorphology of stable, self-formed streams. This dissertation presents methods and equations for incorporating the principals of natural channel design into river …

Hydrological assessment and modelling of the River Fani Catchment, Albania
… years. Rubik lies within the Catchment of the River Fani which is remote, ungauged and characterised by frequent flooding, erosion and deforestation. Over the years these processes have had a huge environmental and socioeconomic impact on the residents of Rubik. Aid In Action was concerned …

Velocity distribution prediction in rectangular and compound channels under smooth and rough flow conditions
Many practical problems in river engineering require predictions of velocity distributions in single and compound open channels. In this study, velocity distributions in rectangular and compound open channels under different flow regimes, in terms of roughness and turbulence conditions, were …

Under what conditions do parallel channel networks occur?
Geologists have long recognized that channel networks can deviate from a typical dendritic form when they develop under certain geologic or topographic constraints. One such deviation is the so-called parallel form, which is thought to develop when the pre-existing surface is sloping. The …

Utilizing archival data to assess historic changes in flood flow conveyance of the Mississippi River
The assessment of change in river systems requires reference conditions. However, most large navigable waterways in the United States and elsewhere around the world have a wealth of archival data because of past engineering projects and flood control efforts. For example, in the United States, …
