ASSESSMENT OF GROUNDWATER CONTROLS TO PROTECT OAKLAND ATHLETICS’ PROPOSED WATERFRONT BALLPARK
In 2019, the Oakland Athletics baseball club was proposing a new baseball stadium along the waterfront on the Inner Harbor of Oakland, which connects to the San Francisco Bay and is located north of Jack London Square. The proposed site was at the historic Howard Terminal, which has been used since the late 1800s for container cargo operations. The proposed stadium location was designed to revitalize the area while maintaining historical features that speak to the history of the Howard Terminal and the importance of maritime commerce in Oakland. LWS was retained to evaluate groundwater issues associated with the proposed stadium location.
Although the Athletics ultimately decided to move out of Oakland, the studies for the former proposed ballpark are unique and interesting….
Numerical Groundwater Flow Modeling, Part 4
In Part 3 (February 2, 2022) of the LWS series on numerical groundwater modeling, we described the basic elements of the groundwater flow equation. This week’s LWS blog describes the use of model grids to describe hydraulic properties.
Groundwater Flow Modeling - Methods
A model of any natural system is a simplified representation of that system. Groundwater models incorporate parts of the hydrologic cycle that effect groundwater. A groundwater model is a mathematical representation of a groundwater flow system. There are three main types of groundwater models…
Numerical Groundwater Flow Modeling, Part 3
The previous blog on numerical groundwater modeling described the process of selecting the model boundary or bounding the model domain. This week’s LWS blog describes what hydraulic properties are necessary for solving the groundwater flow equation.
Numerical Groundwater Flow Modeling, Part 2
This blog is the second in a series on numerical groundwater models. These blogs are meant to be informative on the basic approach to modeling groundwater and what makes a model a good tool. For a tool to be effective, it should be the correct shape and size for the user. This blog describes why model boundaries are important and necessary for a model budget.
Numerical Groundwater Flow Modeling, Part 1
This is the first in a series of blogs on the topic of numerical groundwater flow modeling. The concept of groundwater flow, introduced here, is fundamental to groundwater modeling. Groundwater flow is fairly easy to understand because it is analogous to heat flow, which we experience nearly daily….
Deep Bedrock Wells for Municipal Use: A Series on the Process - #7) Water Quality Testing
Welcome to the seventh and final installment in our well drilling series following the construction of Monument Well 10 by Layne, A Granite Company, and Lytle Water Solutions! In our previous blogs we covered the borehole drilling, geophysics/well design, well installation, gravel packing/grouting, well development, and well testing. Now we move on to the water quality testing of the well.
Deep Bedrock Wells for Municipal Use: A Series on the Process - #6) Well Testing
Welcome to the sixth installment in our well drilling series following the construction of Monument Well 10 by Layne, A Granite Company, and Lytle Water Solutions! In our first five blogs we covered the borehole drilling, geophysics/well design, well installation, gravel packing/grouting, and development. Now we will move on to the testing of the well.
Deep Bedrock Wells for Municipal Use: A Series on the Process - #5) Well Development
Welcome to the fifth installment in our well drilling series following the construction of Monument Well 10 by Layne, A Granite Company, and Lytle Water Solutions! In the first blog we talked about how the borehole for the well is drilled. In the second blog we discussed the basics of geophysical logging and well design. In the third blog we discussed the installation of the well itself in the borehole, while the fourth blog discussed the installation of the gravel pack and grout seal. Now we will move on to the development of the well in this fifth blog of the series.
Deep Bedrock Wells for Municipal Use: A Series on the Process - #4) Well Gravel Packing & Grouting
Welcome to the fourth installment in our well drilling series following the construction of Monument Well 10 by Layne, A Granite Company and Lytle Water Solutions! In the first blog we talked about how the borehole for the well is drilled. In the second blog we discussed the basics of geophysical logging and well design, and in the third blog we discussed the installation of the well casing and screen in the borehole. Now that the well has been set to total depth in the borehole, it is time to go over the process of finishing the well completion with the gravel packing and grouting process.
LWS Collaborative Work on Groundwater Modeling, Groundwater Hydrology and Surface Water Hydrology Projects
LWS’ areas of expertise include surface and groundwater supply development, water supply planning, surface and groundwater modeling, water rights, environmental permitting, and expert testimony. By collaborating with other small- to medium-size firms we are able to create work products normally produced by much larger engineering firms and with a lower overhead cost and a higher quality product.
