This study presents a multi-disciplinary approach for investigating the interactions between groundwater and surface water in the semi-arid Hailiutu catchment in the Erdos Plateau, Northwest China. The study consists of statistical detection of river flow regime shifts at the basin level; multiple in-situ measurements for quantifying groundwater discharges using hydraulic, hydrochemical and temperature methods at a local scale; analysis and simulation of impacts of different land use scenarios on groundwater and surface water interactions at the sub-catchment scale; and the quantification of temporal and spatial groundwater and surface water interactions with hydrochemical tracers and modelling methods at the basin scale. The study found that the river flow consists of mainly groundwater discharges at all scales. The river flow regime has been intensively altered by human activities, such as the construction of reservoirs, water diversion, groundwater exploitation, and reforestation. Water use by plants and crops consumes majority of the precipitation. Groundwater sustains vegetation growth and feeds river discharges. The water resources and ecosystem management priority should reduce evaporative water uses by promoting dry resistant plant species for vegetating sand dunes and lower irrigation demand crops for socio-economic development. Furthermore, the Hailiutu River catchment must manage the groundwater recharge for water resource conservation and the maintenance of healthy ecosystems.

To promote scientific understanding of surface processes in East Asia, we have published details of the CMADS dataset in the journal, Water, and expect that users around the world will learn about CMADS datasets while promoting the development of hydrometeorological disciplines in East Asia. We hope and firmly believe that scientific development in East Asia and our understanding of this typical region will be further advanced.

This dissertation investigates groundwater-surface water interactions and stakeholder engagement for an unconfined aquifer in the Central Sands region of Wisconsin, USA. The study focuses on two surface water systems, the Little Plover River and Long Lake, which over the last several decades received much public attention related to consecutive years of low flows and water levels. The dissertation is comprised of four papers. The first paper applied collaborative modeling and scenario analysis using soil water balance and groundwater flow models to simulate stakeholder-identified water management scenarios in the Little Plover River basin under historically-informed dry, average, and wet weather conditions. The process provided a forum for solution-based discussion between multiple interest groups. Results compared impacts of ten scenarios on the Little Plover River and showed that scenarios must be applied in combination to have significant impacts on stream flows. The second paper applied qualitative research methods - group meetings, surveys, and individual interviews - to investigate stakeholder perspectives of groundwater flow models and the scenario analysis process in the Little Plover River basin. Narrative inquiry, a qualitative method that has not been applied to water resources research, elucidated key tensions that can be the focus of future collaborative modeling efforts. The third paper developed a method for reconstructing a long-term record of lake levels using personal photos along with aerial photos and available, but limited, monitoring data. The method resulted in reconstruction of an 80-year lake level record (1938-2017) showing a long-term lake level fluctuation of 9.4 feet over the record. The approach could be used to create datasets in areas that have little to no monitoring data. In addition, visual documentation of personal photos and aerial photos can build stakeholder trust in reconstructed long-term records. The final paper investigated lake-aquifer connectivity of Long Lake. Methods characterized the local hydrostratigraphy, calculated groundwater flow with a stable isotope water budget, and analyzed lake and groundwater levels and vertical gradients. Results from all methods showed the lake is well-connected to the surrounding aquifer, and how using multiple lines of evidence is a useful approach for investigating lake-aquifer connectivity.

Watershed management issues are among the many challenges facing natural resource managers in British Columbia. This assessment, combined with a compilation of relevant research and data/information sources for northeast British Columbia, forms the basis for developing an applied research strategy to support sustainable water resource management in this region. This report presents the data collection methods used in the survey, a profile of the respondents, the ranking (High, Moderate, Low) of key research needs by topic area within each theme, and a summary of the written comments for each of the five main topical themes.--Includes text from document.

Rapid population growth and climate variability have been posing pressure on groundwater management, especially in regions dominated by irrigation agriculture. Effective management practices require a better understanding of groundwater dynamics and its contributing factors, such as recharge, groundwater-surface water interactions, soil and unsaturated zone characteristics. Although groundwater models can provide valuable insights into these questions, these models are often nonexistent or cost prohibitive. The purpose of this study is to use a data-driven approach to understand the spatiotemporal dynamics of groundwater level observations. Using the Platte River Basin in Nebraska as the study area, I examined explanatory factors (e.g. precipitation, pumping and streamflow) that may be associated with the dynamics of groundwater table using data mining techniques. Groundwater level data from 14 wells during the time period of 2000-2018 was used for this study. Two different approaches for examining the spatial and temporal datasets were employed and compared. In the first approach, I used the principal component analysis (PCA) and a cluster analysis to group the wells into three different clusters. A cross-correlation analysis was then used to associate the clusters with explanatory variables. In the second approach, I used multivariate singular spectrum analysis (MSSA) to decompose the time series into three components, including trends, seasonal and other oscillatory signals. Then a time series clustering method was adopted to divide the wells into different groups. The oscillatory signals from the MSSA and time-series clustering were used to examine temporal dynamics of each group of wells. Both approaches were found to be useful in understanding the spatial pattern and explanatory factors influencing the groundwater level variations. The spatiotemporal variations in groundwater levels in the Platte River Basin were found to be influenced by groundwater pumping, natural recharge and hydrological connection with the Platte River and its tributaries in varying degrees. This study shows that data mining is a useful tool to understand groundwater resource dynamics.

"Flooding can have devastating impacts on peoples livelihood, economy and the environment. One way to minimize flood losses is using floodplain maps, which assist land planners and local authorities in identifying flood-prone areas, and provide useful information for rescue and relief agencies for their operations. Developing floodplain maps often involves flood inundation modeling. This typically requires precipitation and stream flow data, topographic information, the selection of a hydraulic model and the calibration of its parameters. A common representation of floodplain map is based on a single outcome without an explicit consideration of all the sources of uncertainty in the modeling process. The research presented in this thesis addresses the uncertainty in the flood inundation modeling, which may arise from input data and hydraulic modeling approach. The study area is the Sungai Johor basin in Johor, Malaysia, which is an agricultural dominated area.By using a set of sample data for Sungai Johor Basin, the case study show the uncertainties arising from an estimation of design flow, terrain data sets, geometric description in hydraulic models and different modeling approaches.The intent of the research in flood inundation maps is to emphasize the impact of uncertainties in flood inundation maps that not only provide useful results but also suggested further research and improvement of flood inundation mapping practices."--Provided by publisher.
