Rainwater Utilization To Reduce Flooding In Low-Lying Areas Of Taipei City, Taiwan, Andrew Lo

Journal of Marine Science and Technology–Taiwan

She-Zih is a low-lying area in Taipei City where the Tanshui River and Keelung River meet. Average elevation is about 2.5 m. Perennial flood events occur very often. The only flood prevention facility is the 6 m levee built around the perimeter to overcome 20-yr flood events. The main cause of the flooding problem is the instantaneous extreme high rainfall events that often exceed the drainage capacity of She-Zih. Current solutions to relieve this water hazard, suggested by the Water Resources Agency, include channel widening and many water pumping installations. At present, all emergency facilities are insufficient to combat unexpected …

Early-Summer Ichthyoplankton Biodiversity Associated With Oceanic Factors On The Continental Shelf Of The Southern East China Sea, Wen-Yu Chen, Yi-Chen Wang, Ming-An Lee

Journal of Marine Science and Technology–Taiwan

Ichthyoplankton communities associated with oceanic factors on the continental shelf of the southern East China Sea were studied in early summer 2009. Temperature and salinity of the stations in this survey respectively varied 13.78~ 27.86°C and 33.14~34.77 psu. In total, 1204 fish larval individuals belonging to 62 families and 120 taxa were identified. Using a cluster analysis, the spatial distributions of larval fish were classified into 3 groups: a coastal group, a shelf group, and an offshore group. The offshore group was further divided into 2 subgroups: a mixed shelf group and a Kuroshio group. The coastal group consisted of …

Quantification Of Carbon Emission Reduction By U-Transportation Service Effect: A Case Study Of Dongtan U-City, Tae-Woong Jung, Mu-Wook Pyeon, Jee-Hee Koo

Journal of Marine Science and Technology–Taiwan

With the emergence of the response to climate change as a global agenda, UNFCCC member countries must report their Greenhouse Gas (GHG) emissions and absorptions. With conventional carbon emission estimation methods such as the IPCC Guideline, however, it is impossible to measure reduction of carbon emissions by U-City services. Therefore, this study proposed estimating carbon emission reductions by using U-transportation services as a model because this service appears to be the most effective among U-City services in terms of carbon emission reduction. This approach which is unique in Korea has also attempted to quantify the reduction of carbon emissions by …

Open Source Remote Sensing:Introspect And Prospect, Sanggoo Kang, Hee Young Yoo, Kiwon Lee

Journal of Marine Science and Technology–Taiwan

It is noteworthy that open source applications have been developed and studied in various fields as well as remote sensing field. Open sources for GIS have long history related to open standards over three decades, but those of remote sensing do relatively short. Moreover, there are still no summary reports for open sources for remote sensing. In this study, we summarized characteristics of open source applications for remotely sensed image processing and discussed their strengths and weaknesses at first. Based on the summary, two open source applications for InSAR Processing and Geographic Object-Based Image Analysis are practically implemented to introspect …

Journal of Marine Science and Technology–Taiwan

The Great East Japan Earthquake on 11 March 2011 triggered an extremely destructive tsunami that hit the Tohoku region of Japan severely. According to data from the Ministry of Agriculture, Forestry, and Fishes of Japan, Tohoku accounted for 27.59% of Japan’s rice yield in 2010. It is an impact to a country that relies on rice as its main food source. This paper utilizes remote sensing techniques to estimate the disaster losses in rice field and yield in Fukushima and Miyagi, the most severely damaged coastal prefectures of the Tohoku region, by using a developed Rice field Identification and riCe …

An Object-Oriented Analysis For Characterizing The Rainfall-Induced Shallow Landslide, Kuan-Tsung Chang, Jin-King Liu, Chu-I Wang

Journal of Marine Science and Technology–Taiwan

Landslides are natural phenomena for the dynamic balance of the earth's surface. Because of frequent occurrences of typhoons and earthquakes in Taiwan, mass movements are common threats to people's lives. In this paper, the interpretation of knowledge is quantified as recognition criteria. Multisource high-resolution data, for example, a SPOT satellite image, 20 m × 20 m Digital Terrain Model (DTM) reduced from Light Detection And Ranging (LiDAR) data, and aerial orthophotos were used to construct the feature space for landslide analysis. Landslides were recognized by an objectoriented method combining edge-based segmentation and a Supported Vector Machine (SVM) method. The classification …

Stream-Associated Amphibian Habitat Assessment In The Portland-Vancouver Metropolitan Region, Andrew Evans Dietrich

Dissertations and Theses

This study assessed the influence of landscape development on stream-associated amphibians in forested riparian areas within the Portland-Vancouver metropolitan region. Human alteration of landscapes may dramatically affect the ecology of neighboring aquatic systems. It was hypothesized that lotic amphibians would be negatively associated with greater amounts of landscape development and positively associated with forested area within the surrounding watershed. Thirty-seven 1st-3rd order streams were sampled between June 21st and September 21st in 2011. Streams potentially providing adequate habitat for stream-obligate amphibians were randomly selected. Amphibians were surveyed along 30-meter stream transects using an active-cover search (ACS). Environmental variables associated with …

Water Consumption In Southern Nevada, Paul Conyers

Anthropology 100: Feast and Famine In a Global World Poster Assignment

With its massive hotels, casinos, restaurants, and dramatic architecture it can be easy to forget that Las Vegas resides in the middle of a desert receiving just 4.5 inches of rain per year. Its population has grown immensely to nearly 2 million as of 2012 and that is without including the more than 30 million tourists visiting every year. With this growth more and more water is needed to keep yards and golf courses green, to keep the fountains of Bellagio flowing, to support the habitats of Mandalay Bay and the Flamingo, and to allow Las Vegas to maintain its …

Anthropology 100: Feast and Famine In a Global World Poster Assignment

Southern Nevada is located in the arid Mojave Desert, which averages about 4 inches of rain each year. Southern Nevada gets about 90% of its water supply from the Colorado River. Seven western states and Mexico share the river. This means that The Colorado River provides water to 25 million people.

A Watershed Scale Evaluation Of Selected Second Generation Biofeedstocks On Water Quality, Gurdeep Singh

Graduate Theses and Dissertations

This study compares a novel simulation approach to the conventional Soil and Water Assessment Tool (SWAT) modeler's approach for targeting biofuel crop production on marginal lands. In conventional SWAT modeling approach, non-spatial definition of hydrological response units (HRUs) results in the simulation of biofuel crops on both marginal and non-marginal land. This study provides an alternative approach in which a marginal-land raster was integrated into the land use and land cover (LULC) raster in such a way that the land uses were divided into marginal and non-marginal components. This modified LULC was used for model setup which resulted in marginal …

The Use Of Tree Rings To Study The Impacts Of Stream Flow And Climate Variability On Native And Invasive Woody Species Along A Semi-Arid Riparian Ecosystem In The Great Plains, Usa, Kristen M. Skolaut

School of Natural Resources: Dissertations, Theses, and Student Research

Forested riparian areas of the Northern Great Plains have historically been dominated by the native Populus deltoides L. vegetation type. Changes in climate, stream flow, groundwater, and management practices in the past few decades have promoted the expansion of the upland native woody species Juniperus virginiana L. and the invasion of the non-native Elaeagnus angustifolia L. into these riparian ecosystems. This study aims at using dendrochronology, or the study of tree rings, to assess the impacts of intra- and inter- annual climatic variability and stream flow over the past decades, on the annual tree ring growth, oxygen and carbon isotopic …

Autumn Migration Of Mississippi Flyway Mallards As Determined By Satellite Telemetry, David George G. Krementz, Kwasi Asante, Luke W. Naylor

United States Geological Survey: Staff Publications

We used satellite telemetry to study autumn migration timing, routes, stopover duration, and final destinations of mallards Anas platyrhynchos captured the previous spring in Arkansas from 2004 to 2007. Of those mallards that still had functioning transmitters on September 15 (n = 55), the average date when autumn migration began was October 23 (SE = 2.62 d; range = September 17–December 7). For those mallards that stopped for .1 d during migration, the average stopover length was 15.4 d (SE = 1.47 d). Ten mallards migrated nonstop to wintering sites. The eastern Dakotas were a heavily utilized stopover area. The …

Scientific Basis For Safely Shutting In The Macondo Well After The April 20, 2010 Deepwater Horizon Blowout, Stephen H. Hickman, Paul A. Hsieh, Walter D. Mooney, Catherine B. Enomoto, Philip H. Nelson, Larry A. Mayer, Thomas C. Weber, Kathryn Moran, P. B. Flemings, Marcia Mcnutt

Center for Coastal and Ocean Mapping

As part of the government response to the Deepwater Horizon blowout, a Well Integrity Team evaluated the geologic hazards of shutting in the Macondo Well at the seafloor and determined the conditions under which it could safely be undertaken. Of particular concern was the possibility that, under the anticipated high shut-in pressures, oil could leak out of the well casing below the seafloor. Such a leak could lead to new geologic pathways for hydrocarbon release to the Gulf of Mexico. Evaluating this hazard required analyses of 2D and 3D seismic surveys, seafloor bathymetry, sediment properties, geophysical well logs, and drilling …

National Drought Mitigation Center: Faculty Publications

As the climate in the midwestern United States becomes increasingly variable because of global climate change, it is critical to provide tools to the agricultural community to ensure adaptability and profitability of agricultural cropping systems. When used by farmers and their advisors, agricultural decision support tools can reduce uncertainty and risks in the planning, operation, and management decisions of the farm enterprise. Agricultural advisors have historically played a key role in providing information and guidance in these decisions. However, little is known about what these advisors know or think about weather and climate information and their willingness to incorporate this …

This presentation will consider the implications of the November 6th election on short and long-term climate policy initiatives.

Climate Change And The Water Crisis In Israel, Lauren Deutsch

Natural Resources Management and Environmental Sciences

Israel’s water crisis is controlled by the availability and location of water resources that are affected by climate change and geopolitics in southwest Asia. Conflict between Israel and the Palestinian occupied territories in the Gaza Strip and the West Bank have put strains on the allocation of water recourses. The goal of this research was to model how much a change in climate will affect the amount of available freshwater in Israel. Intensive research taken from Israel and the occupied territories was carried out to understand how the amount of precipitation, rainfall, and the rate of evaporation is affected by …

Water: Conserving Our Most Precious Resource, John Holmes Gcvo, Kbe, Cmg

Reports (USI)

This was a thoughtful discussion on a vital and still neglected issue. While there was enough fresh water in the world overall, its distribution did not match that of the global population. Climate change, continuing population growth, urbanisation and altered dietary habits were all exacerbating existing problems of fresh water availability. But there was little new action at national or international level, though local and private sector decisions were making a difference in some places. In the end we might have to take the water to the people rather than expecting the people to go to the water, as had …

Tornado Warnings In Three Southern States: A Qualitative Analysis Of Public Response Patterns, William Donner, Havidan Rodriguez, Walter Diaz

Sociology Faculty Publications

Recent research in three Southern states supplied data describing the role community structure and culture played in shaping public response to tornado risks. The following study identifies and describes how residents received, made sense of, and ultimately used information to make decisions about responding to warnings. In addition to a range of theoretical concerns, research was also intended to develop a set of safety policies derived from what the data reveals about the social psychology of risk perception, economic constraints to shelter, and the cultural aspects of response.Data analysis reveals a diverse set of social factors governing community response to …

Fecal Indicator Bacteria In Knitting Mill Creek With A Comparison Of Methods Used To Enumerate E. Coli, Manju Nagarajan

OES Theses and Dissertations

This research seeks to evaluate the impact of an urban, multi-use neighborhood on the bacteriological quality of water in Knitting Mill Creek, a blind arm of the Lafayette River, a sub-estuary of the lower Chesapeake Bay. A principal objective was to determine the effects of rainfall, a surrogate for run-off, on water-column concentrations of fecal-indicator bacteria (FIB). I collected water samples weekly (September 2009-December 2010) and biweekly (January 2010-December 2011) at a storm-sewer outfall and a nearby marina and quantified their E. coli and enterococci concentrations using Colilert-18 and Enterolert, most-probable-number assays. In addition, I took monthly samples for these …

Nantucket Shellfish Management Plan, Matthew Herr, Frank Dutra, Tara Riley, Sarah Oktay, Peter Boyce, Doug Smith, Carl Sjolund, Jake Kritzer, Cormac Collier, Dave Fronzuto, Kristin Uiterwyk, Jack Wiggin, Dale Leavitt, Steve Bliven, Allison Novelly, Dan Hellin

Urban Harbors Institute Publications

Nantucket’s shellfisheries are significant both locally and nationally. Locally, commercial and recreational shellfishing are critical to the Island’s history, culture, and economy. Nationally, the Island’s largest commercial shellfishery — the Nantucket bay scallop fishery is one of the last wild-harvest bay scallop fisheries in the country, but there is growing concern over the health of the overall population and the sustainability of the fishery. Given the importance of the shellfisheries on Nantucket and the drastic decline of bay scallop populations elsewhere along the Atlantic coast, there is a compelling interest in ensuring that the Town’s shellfish are managed to sustain …

Catching Air - Those Magnificent Jumping Suwannee Sturgeons, Ken Sulak

United States Geological Survey: Staff Publications

It starts deep at the bottom of the dark silent river, three to four powerful tail beats and three sharp acoustic clicks. Then, a sudden upturn of the body and the fish explodes upward, 100 pounds going vertical, catching air, lots of air. A good jump can power a big fish, six to nine feet into the air. You have to be quick to get a photo, hang time is only about a second, but an accomplished jump by a big old Suwannee River Gulf Sturgeon is impressive; a magnificent display of power. The exit is almost vertical. The tail …

Planning For Sea Level Rise In Portland, Maine Using Robust Decision Making As A Guide, Sadie Lloyd

Muskie School Capstones and Dissertations

This paper evaluates the potential for Robust Decision Making (RDM) to guide communities preparing for the impacts of climate change, using sea level rise planning in Portland, Maine as a case study. RDM is a problem solving process that considers multiple outcomes and an uncertain future, and focuses on decisions that provide benefits regardless of which future scenarios develop, allowing for the adjustment of decisions over time to accommodate changes in the future. The flexibility of RDM makes it an appropriate model for decision makers and stakeholders unsure how to address impacts of climate change, an issue complicated by numerous …

Impacts Of Climate Change On The Surface Water Balance Of The Central United States, 1984–2007, Bo Dong

School of Natural Resources: Dissertations, Theses, and Student Research

The climate system and the hydrologic cycle are strongly connected with each other. Understanding the interactions between these two systems is important, since variations in climate can trigger extensive changes in the hydrologic cycle, with significant impacts on agriculture, ecosystems, and society. Observations over the central U.S. in recent decades show numerous changes in climatic variables. This includes decreases in cloud cover and wind speed, increases in air temperature, and seasonal shifts in precipitation rate and rain/snow fraction. To assess the impacts of these variations in climate on the regional water cycle, a terrestrial ecosystem/land surface hydrologic model (Agro-IBIS) is …
