Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims
Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This article presents a new method for estimating changes in depth to groundwater at a yearly, county level and incorporates these estimates as the dependent variable of econometric models for the High Plains aquifer. The High Plains (Ogallala) aquifer underlies eight states in the central United States and is the primary source of irrigation water for this large food producing region. The stock of groundwater is a finite, non-renewable resource with minimal recharge in most areas. Many fields of study, including hydrology and agricultural economics, are interested in depth to groundwater changes because they serve as a proxy for estimating …

Cockatoo Sands In The Victoria Highway And Carlton Hill Areas, East Kimberley: Hydrogeology, Aquifer Properties And Groundwater Chemistry, D L. Bennett, John Andrew Simons, Richard J. George Dr, Paul Raper
Resource management technical reports
Cockatoo Sands are recognised as potentially suitable for irrigated agriculture because they are generally well drained and not subject to waterlogging or inundation. These characteristics allow them to be cultivated and prepared for planting various crops during the wet and dry seasons of northern Australia. Expanding agricultural production onto the Cockatoo Sands around Kununurra will increase opportunities for agriculture by increasing the overall scale of agriculture, allowing year-round agricultural enterprise, new crops and new market opportunities.
DAFWA has assessed the soil characteristics and agriculturally suitable areas of Cockatoo Sands in the Victoria Highway and Carlton Hill areas near Kununurra. Potential …
Hydrogeological Conceptual Model Of La Villa River Watershed, Republic Of Panama, Maria G. Castrellon Romero
Hydrogeological Conceptual Model Of La Villa River Watershed, Republic Of Panama, Maria G. Castrellon Romero
Honors Scholar Theses
Groundwater in Panama is a valuable and poorly understood resource. Its exploitation has increased 75% in the past decade, reaching a total value of 700,000 m3/day or 185 million gallons per day (MGD). Climate change has caused a lengthening of the dry season, which has reduced precipitation and streamflow, resulting in surface water scarcity during this period. Nevertheless, it has not been possible to determine the extent to which groundwater sources have been affected by these factors since systematic monitoring of groundwater levels has not been implemented in Panama. With support from National Institution of Drinking Water Supply …

Resource management technical reports
Land capability review for the Swan Valley.
The land capability review of the Swan Valley examined and updated previous soil and capability studies done in the area, which are still considered highly relevant for the planning requirements of the Swan Valley. As a result we have updated information on the potential for irrigated agriculture in the Swan Valley which will guide decision-making in the future.
This review uses a modified version of a new approach to presenting information for land use planning, developed by DAFWA in the Mid West region.
The main findings of the review include:
- The alluvial terraces …
Comparison Of The Chemical And Isotopic Composition Of Groundwater And Surface Water In The South Sound Region, Andrew H. Oberhelman
Comparison Of The Chemical And Isotopic Composition Of Groundwater And Surface Water In The South Sound Region, Andrew H. Oberhelman
Summer Research
This project seeks to characterize the chemical and isotopic compositions of groundwater and surface water in portions of Pierce and King Counties, with the goal of using these results to determine the water sources of local lakes. Specifically of interest are lakes studied by Puget Sound students over the past ~10 years where water analyses appear to define a mixing line, likely between surface runoff and the shallow groundwater (Figures 1, 2, and 3). Existing data pertain only to surface water from the lakes while data pertaining to groundwater is patchy or nonexistent and includes only a few of the …

Resource management technical reports
Dryland salinity is a hydrologically driven land degradation hazard in the south-west agricultural region of Western Australia (WA). Shallow-rooted annual crops and pastures transpire significantly less water than the native vegetation they replaced, leading to an increase in recharge, rising groundwater levels and the development of shallow watertables in areas where often none existed previously. Rising groundwater levels mobilise soluble salts, naturally stored at high concentrations in the regolith. These salts can be concentrated in the root zone of vegetation by evapotranspiration.
Fast Neural Network Surrogates For Complex Groundwater Flow Models, Niels Schütze, Tirthankar Roy
Fast Neural Network Surrogates For Complex Groundwater Flow Models, Niels Schütze, Tirthankar Roy
International Conference on Hydroinformatics
Surrogate modeling approach has been adopted in the study to replace computationally expensive physical-based numerical flow and transport model. Two approximate surrogate models namely, Artificial Neural Network (ANN) and Gaussian Process Model (GPM) are developed individually using a scenario database generated from the density dependent numerical flow and transport model OpenGeoSys (OGS). The state-space surrogates have the flexibility to move freely from one point to another within a time frame of decades and also to allow for moderate extrapolation in the case of extreme abstractions. The performance of the GPM was better in many cases with a little compromise on …
Optimization Of Groundwater Remediation With New Efficient Parallel Algorithm For Global Optimization, Min Pang, Christine A. Shoemaker
Optimization Of Groundwater Remediation With New Efficient Parallel Algorithm For Global Optimization, Min Pang, Christine A. Shoemaker
International Conference on Hydroinformatics
Application of optimization algorithm to PDE modeling groundwater remediation can greatly reduce remediation cost. However, groundwater remediation analysis requires a computational expensive simulation, therefore, effective parallel optimization could potentially greatly reduce computational expense. The optimization algorithm used in this research is Parallel Stochastic radial basis function. This is designed for global optimization of computationally expensive functions with multiple local optima and it does not require derivatives. In each iteration of the algorithm, an RBF is updated based on all the evaluated points in order to approximate expensive function. Then the new RBF surface is used to generate the next set …

Hydrogeological Modelling Of Contaminated Area In Tegal, Indonesia, Sapari Dwi Hadian, Syarif Ali, Rifky Meisa, Nursiyam Barkah
International Conference on Hydroinformatics
Small and Medium Enterprises metal smelting in Tegal has been existed since more than 50 years ago. This metal smelting process produces heavy metal waste such as zinc, iron, aluminum and copper which exceed the limit and contaminate the water. These hazardous and toxic wastes are disposed directly into the environment without adequate treatment to remove harmful compounds, thus alleged to have a high level of pollution to groundwater and surface water. The aim of the study is to obtain geological and hydrogeological condition of the study area, so that would be obtained the groundwater impurity pattern in the study …
Does The Risk Of Groundwater Depletion Drive Tube-Well Technology Adoption: A Case Of Pakistan, Arif Watto, Amin Mugera
Does The Risk Of Groundwater Depletion Drive Tube-Well Technology Adoption: A Case Of Pakistan, Arif Watto, Amin Mugera
International Conference on Hydroinformatics
We employ a moment-based approach to empirically analyse farmer’s decisions about adoption of tube-well technology under depleting groundwater resources using a farm level data from 200 farming households in the Punjab province, Pakistan. The results indicate that the higher the expected profit the greater the probability of adoption. Similarly, with increasing variance the probability of adopting tube-well increases significantly indicating that farmers choose to adopt tube-well technology in order to hedge against production risks. Statistical non-significant the third moment i.e., skewness indicates that farmer generally do not consider downside yield risk when decide to adopt tube-well technology whereas highly significant …
Levels Of Data Interoperability In The Emerging North American Groundwater Data Network, Boyan Brodaric, Nate Booth, Eric Boisvert, Jessica Lucido
Levels Of Data Interoperability In The Emerging North American Groundwater Data Network, Boyan Brodaric, Nate Booth, Eric Boisvert, Jessica Lucido
International Conference on Hydroinformatics
The Canadian Groundwater Information Network (GIN) and the US National Ground-Water Monitoring Network (NGWMN) connect data from a variety of sources including states, provinces and federal agencies. Data heterogeneity is a major challenge faced by these networks, one that must be overcome at five distinct levels: systems, syntax, structure, semantics, and pragmatics. This paper discusses approaches taken at each of the five levels to ensure interoperability between the Canadian and American networks. The result is an emerging North American Groundwater Data Network, which enables users to access data transparently and uniformly on either side of the shared border.

Addressing Water Resource Issues In Barbados Through An Isotopic And Atmospheric Characterization Of Precipitation Variability, Veronica Hall
Masters Theses & Specialist Projects
Numerous studies have analyzed isotopic variation of meteoric and dripwater in karst environments for paleoclimate reconstructions or aquifer recharge capacity. What is poorly understood is how the isotopic signal of δ18O and δ2H is transferred through the hydrologic cycle based upon storm type, frequency, intensity, and teleconnection activity in the tropical karst areas. At Harrison’s Cave, Barbados, a Hobo Onset event data logger was attached to a tipping bucket rain gauge to count the tips and record the total rainfall every 10 minutes. In the cave a Hobo data logger was used to record relative humidity …

Groundwater Flow Across Spatial Scales: Importance For Climate Modeling, Nir Krakauer, Haibin Li, Ying Fan
Publications and Research
Current regional and global climate models generally do not represent groundwater flow between grid cells as a component of the water budget. We estimate the magnitude of between cell groundwater flow as a function of grid cell size by aggregating results from a numerical model of equilibrium groundwater flow run and validated globally. We find that over a broad range of cell sizes spanning that of state of the art regional and global climate models, mean between cell groundwater flow magnitudes scale with the reciprocal of grid cell length. We also derive this scaling a priori from a simple statistical …
