Live Webinar - Water Well Design & Site Selection
Bruce Lytle has been invited by Lorman Education Services to instruct an online webinar on Water Well Design and Site Selection on February 18, 2021, 11:00-12:05 MST.
This presentation will cover the fundamentals related to siting wells, well designs, and the design aspects of constructing wells, including materials and parameters related to the casing/screen string, gravel packing, grouting, well development, and testing.

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.
Series: Colorado Water Law Basics #22 - What is Transit Loss?
If you have been involved with a water rights augmentation plan in Colorado, you may be wondering how transit loss works. Who pays for transit loss, who determines transit loss, and does transit loss ever change? We have all those answers for you in today’s blog.
Series: Colorado Water Law Basics #21 - Assessment of a Futile Call
Last week’s LWS blog discussed “What is a Futile Call?”, but how can you evaluate if a futile call is appropriate? A lot has to do with the hydraulic interconnection between the stream channel and the associated alluvial sediments surrounding the channel.
Series: Colorado Water Law Basics #20 - What is a Futile Call?
Normally, when there is not enough water in an administered stream to satisfy all decreed water users’ rights, a “call” is placed on the stream. At these times, under the Doctrine of Prior Appropriation, a “call” is placed with the Water Commissioner, whereby the Commissioner ceases all upstream junior diversions to the extent that the most senior rights are satisfied with the water made available from the curtailment of upstream junior diversions…
Series: Colorado Water Law Basics #19 - Water Rights Abandonment List
Our LWS blogs have discussed how to obtain water rights at length, but we have not talked as much about how you can lose a water right. Outside of selling your water right, abandonment is the primary way water rights in Colorado are forfeited. An abandoned water right simply disappears.
What is Two-Phase Flow and Why is it Important to Avoid in Groundwater Wells?
There are three phases in substances: solid, liquid, and gas. If a mixture of gas and liquid phase flow is encountered in an aquifer, that is known as two-phase flow. Where two-phase flow happens in an aquifer, trouble ensues. There are a number of ways that two-phase flow can develop in aquifers, beginning with the completion and development of a well and continuing with the operation of the well.
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….
LWS and RockWare - A Constructive Collaboration
If a picture is worth a thousand words, what is the worth of a video? When making decisions about a site where the important constituents are hidden underground, a VIDEO is worth more than a picture and much more than words! Lytle Water Solutions (LWS) has found this to be the case in the world of hydrogeology where we are concerned with occurrences happening beneath the ground surface and where the ability to decipher what is going on, and also visualize it, is very beneficial.
Why are Aquifer Tests Important to Understand and Interpret?
Last week we discussed aquifer hydraulic characteristics and what they mean, this week LWS continues with more on that topic. Aquifer hydraulic characteristics are used for a number of reasons, including estimating…
