Impacts to Anadromous Fish through Groundwater Extraction
<p>California uses more groundwater than any other state in the United States in order to meet agricultural demand during the growing season when water is naturally least available due to the state’s Mediterranean climate. The state also hosts populations of anadromous fish that are otherwise found …

Land subsidence caused by pore pressure reduction due to a local groundwater extraction: A study on modelling approaches to predict and describe land subsidence caused by a local groundwater extraction
Land subsidence caused by the extraction of groundwater is a well known problem that could cause large and costly damages to the built infrastructure. This master’s thesis explores the land subsidence resulting from reduced pore pressure due to local groundwater extraction in Gothenburg, Sweden. …

Multi-agent system for future groundwater depletion scenarios using game theory
Groundwater is one of the most vital of all common pool resources throughout the world. More than half of groundwater is used to grow crops. This research models groundwater depletion patterns within a multi-agent system framework. Irrigators are modeled as agents in the multi-agent system. The …

Past And Present Hydrogeology Of The Atacama Desert, Northern Chile: Human And Natural System Interactions
… model. This single-cell model incorporates groundwater outflows such as flow to rivers, wetlands and springs, that depend on the water table elevation. These outflows are modeled as providing economic, social and environmental benefits. The model is applied to a case history of groundwater …

Analysis of sustainable water supply options for Kuwait
… relies heavily on desalination and brackish groundwater extraction. The options considered for increasing the flux of potable water into Kuwait include expanding the desalination capacity, importing water from other countries, expanding the uses of reclaimed wastewater, and rainfall …

Water security in refugee host communities: Syrian refugees in Jordan
… are scarce. I adapt a dynamic economic model of groundwater extraction to analyze the environmental impact of the Syrian refugee influx from 2013 onward on the Amman Wadi As-Sir aquifer in the northern region of Jordan. I then show that, given model assumptions, agricultural producers in the …

Three Essays in Environmental, Labor, and Education Economics
… is not. For instance, when farmers adopt groundwater extraction technology, they need to learn their private marginal cost and marginal benefit of extracting water. Comparing the extraction behavior of the owners of new wells with old wells, we explore the role of experience in shaping …

Assessing Various Technologies to Remediate a Hydrocarbon Contaminated Aquifer
Releases of nonaqueous phase liquids (NAPLs) to groundwater systems are a serious and widespread problem throughout the United States. Research was conducted to determine if numerical groundwater flow and transport models could evaluate the effectiveness of alternative remedial strategies to reduce …

A Numerical and Statistical Analysis of the Fractured Rock Aquifer System in Ploemeur, France to Quantify Local and Regional Recharge
Groundwater recharge is an essential metric for understanding and protecting groundwater resources. Quantifying this parameter remains extremely challenging due to the uncertainties associated with the extent to which the vadose zone affects groundwater movement and the highly heterogeneous nature …

Techno-Economic Evaluation of Conventional Activated Sludge and Membrane Bioreactor Systems for Textile Wastewater Treatment in Bangladesh
… rapid urban growth has caused an increase in groundwater extraction throughout industrial areas including Dhaka and Narayanganj. The environmental regulations now demand textile manufacturing facilities to install effluent treatment systems. The research evaluates Conventional Activated Sludge …

Field Investigation of Stream-Aquifer Interactions: A Case Study in Coastal California
… The aquifer is an important source of groundwater for cropland irrigation and for aquatic ecosystem support. The potential for groundwater pumping to deplete Scotts Creek stream flows is a source of serious concern for land managers, fisheries biologists, and regulatory agencies due to …

Behavioral responses and policy evaluation: Revisiting water and fuel policies
… <p>My first essay focuses on decreasing groundwater depletion through increasing irrigation efficiency in Mexico. I quantify the impacts of different sources of inefficiency on groundwater extraction, and I evaluate the effectiveness of alternative policies that aim to reduce the …

Advanced Fog Harvesting Techniques
… Traditional water sourcing methods—such as groundwater extraction, rainwater harvesting, desalination, and surface water diversion—often rely on significant infrastructure or existing water bodies. Atmospheric water harvesting (AWH) has emerged as a promising and adaptable alternative that …

Natural arsenic and uranium accumulation and remobilization in different geological environments
… German sediments and their potential impact on groundwater quality, let alone a systematic overview of the country´s natural occurrences. This work aims at characterizing accumulation processes in aquifers actually or potentially affected by elevated concentrations of As and/or U, and their …

Impact of climate variability and human activities on water resources.
… which the global driving forces (climate change, groundwater dynamics, etc.) and human activities (land-use/land-cover changes, dam construction, etc.) interact and affect the hydrological regime in some selected basins in the semi-arid region of southeastern Spain. To conduct a comprehensive …

Essays in water resource economics
… variables. Econometric analysis on well-level groundwater extraction data in Nebraska shows that farmers indeed respond nonlinearly to daily climate variables and thus that the use of time-aggregate climate variables is not desirable. Further, by comparing regression results on the real data to …

Bodenbewegungen infolge von Sümpfungsmaßnahmen für tiefe Tagebaue am Beispiel des Rheinischen Braunkohlenreviers
Lowering the groundwater table for the purpose of open-cast mining causes settlements over a wide area usually affecting the whole mining region and the surrounding areas. The lowering reduces the soil buoyancy in the affected layers thus causing settlements, while the reverse effect of the …
