This presentation was made at the 2012 ASCE-EWRI Hydraulic Measurement and Experimental Methods conference in August 2012 at Snowbird, Utah. The presentation describes the spatial variability of surface water characteristics at Big Creek Lake during a four-week study in October 2011. These data were collected as part of Dr. Whelton and Dr. Webb\'s Field Analysis and Sampling Techniques in Civil Engineering (FAST CE) course.

A research paper published in the Proceedings of the National Academy of Sciences. The paper evaluated the level of methane in groundwater in Colorado going back 25 years. It finds the rate of groundwater methane did not change after the introduction of horizontal drilling combined with high-volume hydraulic fracturing in 2010. That is, fracking does not increase methane migration.

This presentation was given as part of the EPA-funded Catchment Science and Management Course focusing on Integrated Catchment Management, held in June 2015. This course was delivered by RPS Consultants. If you have any queries or comments, or wish to use the material in this presentation, please contact catchments@epa.ie
It is increasingly being recognised internationally that integrated catchment management (ICM) is a useful organising framework for tackling the ongoing challenge of balancing sustainable use and development of our natural resource, against achieving environmental goals. The basic principles of ICM (Williams, 2012) are to:
• Take a holistic and integrated approach to the management of land, biodiversity, water and community resources at the water catchment scale;
• Involve communities in planning and managing their landscapes; and
• Find a balance between resource use and resource conservation
ICM is now well established in Australia, New Zealand, and the United States. In Europe the ICM approach has been proposed as being required to achieve effective water and catchment management, and is the approach being promoted by DEFRA for the UK, where it is called the “Catchment Based Approach” (CaBA). The principles and methodologies behind ICM sit well within the context of the Water Framework Directive with its aims and objectives for good water quality, sustainable development and public participation in water resource management. In Ireland it is proposed that the ICM approach will underlie the work and philosophy in developing and implementing future River Basin Management Plans.
Numerical modeling in support of the characterization and remediation of impacted sediments can be a challenging task, particularly in environments where multiple physical processes influence sediment fate and transport. The interaction of various controls is particularly complex in estuarine settings, where riverine input, water levels, waves, and other coastal processes combine to create a seasonally dynamic environment. Modeling of such environments requires a comprehensive and integrated approach such that the effects of each process can be assessed individually, as these processes can be allowed to interact to reproduce the natural environment as faithfully as possible
Approach and Activities
This contribution describes the development and calibration of an integrated Delft3D numerical model that includes flow, sediment transport, wave processes, and vegetation. The model boundary conditions are based on data collected during a comprehensive field program. Field data were also used to calibrate various model input parameters (such as bed and vegetation roughness). The model was used to understand erosion and deposition during both low and high flow regimes, and thus to aid in understanding important controls on sedimentary dynamics during these predominant regimes.
Results and Lessons Learned
The integrated numerical model predictions capture important sedimentation, erosion, velocity, and water level patterns. Model predictions indicate that during periods of low riverine input, velocity patterns and sediment transport associated with periodic water level changes dominate. During riverine flood conditions flow and sedimentation patterns are controlled by the river itself. Integrated modeling of this setting, including calibration to field data provides a valuable tool for assessment of future conditions, and thus for remediating impacted sediments.

8. PWC-based Mapping System HMEM 2012
PWC Mapping
Overview
The PSK system analyzes water
continuously, but only reports a
sample about every 10 seconds
Each sample is automatically geo-
referenced and synchronously
saved to the onboard computer
ADCP surveys were conducted
first, then the study area was
covered at high speed ~15 m/s
Each deployment was completed in
~2 hours
8 Webb & Whelton
10. Results HMEM 2012
• Study results:
Overview – Results consistent
Some data show a statistical
significance between the WQ east
– Lake generating TOC
and west of the raw water intake
• PWC-based results:
Relationship of WQ for Hamilton
Creek and raw water intake is – Comparison to other
inconclusive for most parameters
methods
WQ characteristics at raw water
intake likely constitutes a mixture – Statistical segregation of
of water to its east and west, but
influence of Hamilton Creek is study area
clear for some parameters
– Comprehensive WQ
TOC values statistically similar
within lake, but unique from mapping
streams
10 Webb & Whelton
23. Conclusions HMEM 2012
• Base flow conditions
• Method agreement
• Statistical significance
east/west
• Conductivity always
significantly higher @
Hamilton Creek
• Lake generates TOC
• Intake water exhibits
characteristics of
east/west WQ

24. Future Work HMEM 2012

Future work at Big Creek
