Abstract:

The objective of this study is to estimate 2-D spatial distribution of hydraulic conductivity (Ks) of Zhuoshui River alluvial fan, Taiwan, using groundwater level data from 88 wells and stream stage data from 4 gauging stations. In order to accomplish this analysis, wavelet analysis is first carried out to investigate the periodic cycles of groundwater level, precipitation, and stream stage. The results of the analysis show that variations of groundwater level and stream stage are highly correlated in terms of seasonal and annual periods. Subsequently, seasonal variations of groundwater level

Abstract:

Alluvial fan surfaces in the Atacama Desert of northern Chile preserve evidence of recent, precipitation-driven, surface flows. Determining the hydrologic characteristics of these flows is important for understanding the effects of rare yet significant storms in the region. Flow reconstruction, runoff analysis, and comparison with climatological data yield surface activation recurrence intervals of ~1-20 years for three small fans and associated catchments proximal to Iquique and Antofagasta. Relatively short-lived and intense precipitation events (1-3 hour, > 4 mm/hr) are required to mobili

Aims of this Ph.D. were addressed processing a digital elevation model (DEM) of the study area in a GIS platform to define the several alluvial fans, and thus to examine their history and palaeohydrology. Three OSL dates in the youngest parts of the fans show ages ranging from 74 - 31 ka. Howe

A minor eruption of Mount Saint Helens in Washington State U. S. A. in 1984, triggered the formation of a debris flow in the headwaters of the North Fork Toutle River. As the debris flow progressed downstream it transformed through the incorporation of water and the loss of sediment and within 34 kilometres became a muddy flood. The deposits produced by the transforming flow and associated recessional flows that followed in its wake, exhibited a coarse grained depositional continuum from debris flow to stream flow, including deposits with intermediate sedimentological characteristics termed "h

Abstract:

Alluvial fans represent small-scale coupled transport/depositional systems that provide the opportunity to undertake detailed studies of non-equilibrium landform behaviour. Previous interpretation of fans in the field has tended to emphasize the importance of external controls on their evolution (climate, tectonics and base-level change). Recent investigations, however, have shown that internal process-driven feedbacks may be equally important. This thesis presents results from a series of laboratory experiments designed to quantify the role of internal feedbacks as controls on alluvial fan ev

Discrete formations historically have not been distinguished near the uplift, but this study identified several separate successions in the Richardson Amphitheater. Research at the Richardson Amphitheater, ~12 km southwest of the uplift and ~30 km northeast of Moab, Utah, led to a systematic subdivision of the Permian Cutler Formation

The eastern California shear zone (ECSZ) and Walker Lane belt represent an important inland component of the Pacific-North America plate boundary. Current geodetic data indicate accumulation of transtensional shear at a rate of ~9.2 ± 0.3 mm/yr across the region, more than double the total geologic rate (<3.5 mm/yr) for faults in the northern ECSZ over the late Pleistocene [Bennett et al., 2003, Kirby et al., 2006, Lee et al., 2009, Frankel et al., 2007].

Several hundred meter thick alluvial fans are dominating the landscape of semiarid plains of north-eastern Iranian mountain-talus. These fans developed since Miocene times and are still prograding today. They are storing and transporting major amount of weathered debris from the mountain ranges and sediments are directed to the depressions of the endorheic basins. In this course, the debris gets increasingly weathered and abraded to sand silt and clay fractions, which finally constitute the fine loamy layers of the typical central playa lakes and playas.

碩士<br>國立成功大學<br>資源工程學系碩博士班<br>100<br>This research used PCA (Principle Component Analysis) to analyze month average groundwater level from 2007 to 2010 at Choshui River alluvial fan. The four principle components were extracted from the groundwater level of each aquifer of Choshui River alluvial fan. These components were used to compare to the local hydrology phenomenon and to conjecture the driving force of groundwater level change. The PCA was also applied to analyze the short-term groundwater level change during each typhoon at Choshui River alluvial fan. Thirteen rainfall intense from

碩士<br>國立成功大學<br>資源工程學系碩博士班<br>101<br>During the 1970s, the agriculture and aquaculture in Choushui river alluvial fan grew dramatically. Due to the lack of sufficient surface water, most amount of groundwater has been pumped from well, resulting in subsidence. In recent years, the main subsidence areas gradually move inland, causing the security issues of Taiwan High Speed Rail. In order to reduce groundwater pumping, Changhua and Yunlin upcoming construct artificial lakes and reservoir separately. The purpose of this study is simulating groundwater flow and subsidence in Choushui river alluvi

碩士<br>國立臺北科技大學<br>土木與防災研究所<br>100<br>Groundwater is one of the most important water resources. To compare with surface water, groundwater has the advantage of cheap cost, stable temperature and yield, excellent water quality and convenient acquisition. Nowadays, the substantial amount of groundwater has been still extracted to supply agriculture, aquaculture, household and industry needs in many southwestern Taiwan. If groundwater is polluted, the balance of regional water resources supply may be broken and polluted groundwater poses a threat to human health. Therefore, groundwater resources c

Groundwater level changes during earthquakes were recorded widely. The groundwater monitoring network established by the Water Resources Bureau to the west side of Chelungpu fault recorded the groundwater level changes during the Chi-Chi earthquake. In this research, records of six wells were chosen for simulation from Jhuoshuei River alluvial fan study area. They are Hao-Hsiu, We

碩士<br>國立中央大學<br>應用地質研究所<br>104<br>Land subsidence due to groundwater exploitation is an urgent environmental problem in Chou-Shui river alluvial fan in Taiwan. Aquifer storage and recovery (ASR), where excess surface water is injected into subsurface aquifers for later recovery, is one promising strategy for managing surplus water and may overcome water shortages. The performance of an ASR scheme is generally evaluated in terms of recovery efficiency, which is defined as percentage of water injected in to a system in an ASR site that fulfills the targeted water quality criterion.

Abstract:

碩士<br>臺灣大學<br>生物環境系統工程學研究所<br>98<br>The groundwater resource is abundant in Taiwan and it is making a critical issue to exploit groundwater resource properly. Groundwater resources could be well managed and utilized if the storage and movement of groundwater is rationally evaluated. The continually declining groundwater level in Chou-shui river alluvial fan is mainly caused by the unregistered pumping by private wells due to enormous water demand from agriculture and aquaculture, in turn leading to land subsidence and soil salination. In addition, the construction of Taiwan High Speed Rail (TH
