A Numerical Study On Hydraulic Characteristics In The Ice Harbor-Type Fishway, Seojun Kim, Kwonkyu Yu, Byungman Yoon, Yoonsung Lim

Journal Articles

Recently various types of fishways have been developed and constructed in order to preserve diversity of fish species and restore the riverine ecological system. Some of the fishways in Korea, however, seem to be designed and installed without careful study on their functions and swimming characteristics of target fishes. The present study aims to elucidate proper hydraulic characteristics of the Ice Harbor-type fishway. In the present study, we analyzed the hydraulic characteristics depending on changes in the spans of walls in the Ice Harbor-type fishways, by using Flow-3D, a three dimensional numerical simulation program. Two physical experiments were performed to …

As Unidades De Conservação E A Floresta Ombrófila Mista No Estado Do Paraná, Paulo Dt Dl Pires, Douglas Magnus Zeni Jr, Debora Gaulke

Daugherty Water for Food Global Institute: Faculty Publications

O intenso processo de ocupação territorial, uso desordenado dos recursos naturais e destruição de áreas verdes iniciadas no século XIX, são os principais motivos da intensa devastação das Florestas com Araucárias. Como meio de efetivação da proteção e desenvolvimento florestal, o Brasil adotou em sua política ambiental a criação do Sistema de Unidades de Conservação nas categorias, de proteção integral e uso sustentável. Uma alternativa viável é a regulação dos estoques de madeira no Estado por meio de Unidade de Conservação de Uso Sustentável. O que se pretende a partir deste ponto é analisar a possibilidade da criação de regulamentação …

Application Of A K-Nearest Neighbour Weather Generator For Simulation Of Historical And Future Climate Variables In The Upper Thames River Basin, Leanna M. King

Electronic Thesis and Dissertation Repository

Climate change has the potential to significantly alter the hydrologic cycle, changing the frequency and intensity of precipitation events in an area. It is necessary to quantify these effects to effectively manage water resources in the future. Atmosphere-Ocean coupled Global Circulation Models (AOGCMs), often used in climate change research, have spatial resolutions that are too large to capture the local climate characteristics of a watershed. As a result, several downscaling tools have been developed, including stochastic weather generators. A methodology for the simulation of historical and future climate data using a nonparametric K-Nearest Neighbour block resampling weather generator with perturbation …

Reports have been issued annually since December 2001. The text of the statute applicable to this report follows: “The Department of Environmental Quality shall prepare a report outlining the extent of ground water quality monitoring conducted by natural resources districts during the preceding calendar year. The department shall analyze the data collected for the purpose of determining whether or not ground water quality is degrading or improving and shall present the …

Development Of A Low Cost Instrument For Tidal Flow Measurement, Thomas Daly

Theses

This project examines current technology for the production of energy from wave and tidal sources and the pros and cons of the different types of technology available. It also looks at the possibility of producing energy from tidal streams on a micro scale for local use. It identifies some of the barriers to this and attempts to solve one of those barriers by developing a low cost instrument which would be capable of assisting in the surveying of possible sites for micro tidal energy production in a cost effective way.

As part of this process an off the shelf marine …

Numerical Modelling Of The River Bandon, Stephen Finn

Theses

Numerical modelling involves the use of data from the physical environment and mathematical equations to achieve predictive solutions to many engineering problems including for river engineering. The field data is surveyed, sampled, recorded and tested before it is entered into the numerical modelling program for analysis. The numerical modelling program contains various mathematical equations that solve the data that has been entered. Numerical modelling is an important tool for predicting the consequences of future events. It can be used for predicting the damage of a 1 in 100 year flood event in a river system. Numerical modelling is used by …

Hydraulic Conductivity Of Environmentally Controlled Landfill Liner Test Pad, Camila Maldonado Soria Galvarro

Civil Engineering Undergraduate Honors Theses

Laboratory and field hydraulic conductivity tests have been conducted on soil samples to develop and verify the zone of acceptance for liner placement. Compaction testing and flexible wall hydraulic conductivity tests were performed on fifteen (15) samples to determine the dry unit weight, molding water content, and laboratory permeability. Five of the fifteen samples were compacted at Standard proctor energy, five were compacted at 75 percent of Standard proctor energy, and five were compacted at 50 percent of Standard proctor energy. The results obtained from the laboratory portion of the testing program (the zone of acceptance) are presented. A ten …

Hydroclimatic Forecasting In The Western United States Using Paleoclimate Reconstructions And Data-Driven Models, Christopher Allen Carrier

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis investigated climate variability and their associated hydrologic responses in the western United States. The western United States faces the problem of water scarcity, where the management and mitigation of available water supplies are further complicated by climate variability. Climate variability associated with the phases of oceanic-atmospheric oscillations has been shown to influence streamflow and precipitation, where predictive relationships have led to the possibility of producing long-range forecasts. Based on literature review, four oceanic-atmospheric oscillation indices were identified in having the most prominent influence over the western United States including the El Niño - Southern Oscillation (ENSO), Pacific Decadal …

Technical Note: Friction Factor Diagrams For Pipe Flow, Jim Mcgovern

Articles

This technical note describes diagrams of friction factor for pipe flow that have been prepared using, mainly, the equations that Lewis Moody used to prepare his famous diagram in 1944. The preparation of the new diagrams was prompted by the need for vector graphics versions that could be used for teaching purposes and that could be distributed freely to students and others under a Creative Commons Attribution-Share-Alike license. Using a structure very similar to that of Moody's diagram, variants with the Darcy friction factor and the Fanning friction factor have been prepared. In addition, variants have been prepared that include …

A Three-Dimensional Hydro-Environmental Model Of Dublin Bay, Zeinab Bedri, Michael Buen, Aodh Dowley

Articles

This paper compares a 3-dimensional hydro-ecological model with a 2-dimensional model simulating the distribution and fate of Escherichia Coli (E.Coli) discharges from a sewage treatment plant discharging into Dublin Bay, Ireland. Before being discharged, the effluent from the sewage treatment plant is mixed with cooling water from a thermal generation plant resulting in a warm buoyant sewage plume that can be 7 − 9oC higher than the ambient water in the Bay. The mixing of the stratified plume is complicated by the tidal currents which transport the plume into and out of the estuary. These processes have a direct impact …

The Green, Blue And Grey Water Footprint Of Crops And Derived Crop Products, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

Abstract. This study quantifies the green, blue and grey water footprint of global crop production in a spatially-explicit way for the period 1996–2005. The assessment improves upon earlier research by taking a high-resolution approach, estimating the water footprint of 126 crops at a 5 by 5 arc minute grid. We have used a grid-based dynamic water balance model to calculate crop water use over time, with a time step of one day. The model takes into account the daily soil water balance and climatic conditions for each grid cell. In addition, the water pollution associated with the use of nitrogen …
