This document discusses wetland and stream restoration techniques used following an oil spill from Enbridge's Line 6B pipeline into Talmadge Creek and the Kalamazoo River in Marshall, Michigan in July 2010. Design concepts included creating representative cross sections, assessing shear stresses and plant communities, and using coir logs, backfill, seed mixes, and other materials. Implementation involved restoring creek banks and installing structures like rock chutes, ramps, and wildlife habitat features. Post-restoration monitoring showed regrowth of vegetation and stabilization of restored areas over time. Unique techniques addressed heavy groundwater flows and unconsolidated soils.

The document summarizes a regional geologic evaluation of the Pierre Shale formation for its potential to host a repository for high-level radioactive waste and spent nuclear fuel. The Pierre Shale has desirable properties like its depth, large extent, high clay content, and stable tectonic setting. The evaluation assesses available data on the formation's stratigraphy, hydrogeology, seismic activity, and other features to evaluate its suitability for long-term repository performance. The Pierre Shale is representative of clay-rich Cretaceous formations that warrant further review for a deep geologic repository.

The document provides an overview of streams and stream restoration. It defines what a stream is and discusses fluvial geomorphology and forms. Key concepts covered include meandering streams, bankfull stage, stream ecosystems and functions. The effects of urbanization on streams and symptoms of "urban stream syndrome" are outlined. Factors that contribute to a healthy stream are identified, such as bed stability, sediment transport balance, in-stream habitat, bank stability, riparian buffers, active floodplains, and watershed health. Stream restoration planning and components involving channel morphology, floodplain structure, hydrologic analysis, in-stream structures, habitats and vegetation are summarized. Case studies of stream restoration projects are presented.
The work of rivers
Rivers erode, transport, and deposit material as they flow across the landscape. There are four main types of erosion by rivers: abrasion, attrition, hydraulic action, and solution. Transportation occurs through traction, saltation, suspension, and solution. Deposition takes place when the river's speed or volume decreases, such as when entering a lake or plain. A river's work depends on its energy, which is determined by the volume of water and flow speed according to the gradient.

This document discusses various components of stream restoration including:
1. In-stream structures like logs, rocks, and vanes that provide bank protection, habitat, and sediment transport.
2. Streambank stabilization techniques including temporary matting, root wads, and bioengineering with living plants.
3. Riparian buffers of grasses, wetland plants, shrubs, and trees along the stream banks.

Ridges have lower rates of erosion than coves, resulting in thinner soils and depleted rock-derived minerals. This leads to shorter trees that branch closer to the ground. Coves have higher erosion rates, replenishing soils with minerals and allowing taller trees to grow without branching. Soil samples along hillslopes in El Yunque Forest, Puerto Rico showed decreasing secondary mineral content from coves to ridges, supporting the hypothesis that topography controls forest structure by regulating erosion and soil nutrients.

This document summarizes a study assessing bank stability in Garvin Brook in Minnesota using Rosgen's BEHI/NBS method. The stream was divided into 5 sections and field measurements were used to calculate BEHI ratings, which ranged from moderate to low downstream. NBS ratings throughout were low to moderate. Channel migration rates derived from aerial photos did not correlate well with BEHI/NBS ratings. While Rosgen's method provided some insight, more data like a bank pin study may be needed to fully evaluate bank stability in this stream.

A healthy stream has stable banks and sediment transport, with diverse in-stream habitat and flows. Key factors include stable streambeds and natural floodplains, as well as vegetated riparian buffers. Unstable streams can aggrade or degrade from changes in watershed runoff, sediment loads, slopes, and floodplain or riparian disturbances. Assessing stability uses metrics like entrenchment ratios, meander widths, and bank erosion hazard indices.

This document discusses stream restoration and healthy stream ecosystems. It notes that streams should have a stable bed and banks, allow sediment transport, and have diverse habitat and flows. Unhealthy streams may be straightened and lack buffers. Restoration aims to improve habitat, hydrology, and resilience. Successful projects meet ecological standards and assessment, and have measurable improvements. Design approaches include threshold channels or alluvial channels based on reference reaches, equations, or models to set dimensions, pattern, and profile.
Stream Restoration 101
This document discusses stream restoration and provides guidance on key considerations. It defines restoration as returning a stream to a healthy, functional state. The order of restoration priorities are listed as protect, maintain, restore, and enhance. Successful restoration requires understanding the natural complexity and dynamics of stream systems as well as meeting objectives for stability, function, and accommodation of changes over time. Careful data collection and analysis of hydrology, sediment transport, and geomorphology are crucial to restoration design. Implementation requires attention to construction techniques, habitat enhancements, and transitioning restored areas.

This document provides an overview of the Rosgen stream classification system. It describes the key factors that influence stream morphology and outlines the major stream types according to their physical characteristics such as channel geometry, slope, and landscape position. These include A, B, C, E, F, and G stream types that vary in terms of incision, width, depth, slope, and valley confinement. The Rosgen system involves measuring field parameters like entrenchment ratio, width-to-depth ratio, and substrate to classify streams.
Paper 1 revision 29.5.13 bv
Volcanic eruptions can be monitored and potentially predicted using various methods. Earthquake activity, ground deformation measured by tiltmeters and GPS, changes in magma temperature, and gas emissions are monitored in real-time. Seismometers are also used to analyze earthquake waves. By studying patterns of past eruptions, including the timing of flows and gaps between events, volcanologists aim to improve predictions. However, volcanic eruptions often remain unpredictable.
Spring Green 2008 Flooding and Flood Control Options
1) The 2008 Spring Green flooding was caused by record snowfall and rainfall over wet ground in late 2007 and early 2008, with no outlet for flood waters. This led to over 4,400 acres flooded and damage to homes, businesses, and infrastructure.
2) Modeling showed that constructing drainage basins and outlets could reduce the depth, area, and duration of future flooding, but would require overcoming numerous permitting challenges and coordinating with various stakeholders.
3) Allowing temporary flooding of agricultural fields for a few days was found to be important to implementing a feasible drainage system with multiple constructed outlets to the Wisconsin River.

The document discusses the formation of waterfalls and meanders. It explains that waterfalls form where bands of hard and soft rock create overhangs that eventually collapse, deepening the plunge pool. Meanders form an asymmetrical cross-section due to faster, deeper flow on the outside bend eroding a river cliff, while slower, shallower flow on the inside deposits alluvium in a slip-off slope. Ox-bow lakes form when meander loops are cut off during floods.

This document summarizes a study evaluating passive managed aquifer recharge in the Mississippi River Valley Alluvial Aquifer of northeast Arkansas. Overpumping has caused severe groundwater declines in the aquifer. Common managed aquifer recharge methods like surface spreading and direct injection are difficult due to a confining clay layer. The study is testing infiltration galleries as a potential recharge method. Preliminary results from geophysics, sampling, and modeling indicate galleries could recharge 35-130 liters per minute. Pilot galleries will be constructed and monitored to evaluate recharge rates, water quality impacts, and feasibility of wider implementation.

Glacial System & Environmental Change in Himalaya : Case studies from Nepal
Glacial systems and associated sedimentation processes are changing due to environmental factors like warming temperatures. This causes glaciers to retreat, exposing more sediment. Glacier retreat also forms new lakes that can flood catastrophically if lake dams fail. Several dangerous glacial lakes in Nepal have been identified and studied, including Imja Lake and Tsho Rolpa Lake, which have had water levels lowered to mitigate flood risks. Slope movements also increase hazards and were exacerbated by the 2015 Gorkha earthquake in Nepal. Monitoring, mapping, and risk reduction measures help manage these glacial and paraglacial hazards.

This document describes a project to improve water yields for villages in Tanzania through rainwater harvesting and artificial groundwater recharge. A 1989 water scheme was experiencing declining yields, so from 2006-2014 monitoring and pilots were conducted. A strategy of increasing groundwater recharge through rainwater infiltration was tested. A hillside dam and infiltration pits successfully recharged an estimated 2.5 million liters, increasing dry season yields from 0.3 to 0.8 liters/second. Proper maintenance and community involvement were important to the project's sustainability. While challenges remain, the results demonstrate that rainwater harvesting can significantly improve rural water supplies.7 - Keep Tahoe Blue Lecture Spring semester
Lake Tahoe is an oligotrophic alpine lake located on the border of California and Nevada. It was formed over 2 million years ago and is renowned for its deep blue waters and forested shoreline. However, human activities over the past century have accelerated the natural eutrophication process and reduced water clarity. Increased development, pollution from urban runoff, and the introduction of invasive species have all negatively impacted the lake's ecology. Ongoing restoration efforts focus on improving water quality and clarity through projects that reduce sediment and nutrient loading into the lake. The long-term goal is to restore Lake Tahoe's clarity to the historical depth of 97 feet.

2012 FEPA Presentation: Donald Morris
Safety is a shared responsibility across all levels in a multi-employer worksite. Project owners, general contractors, subcontractors, and employees each play a role. An effective safety culture requires accountability from management to set clear expectations and empower workers. Incidents often stem from organizational and cultural failures, not solely human error. All parties must prioritize safety over other objectives like schedules and costs.
2012 FEPA Presentation: Erik Kirkpatrick

2012 FEPA Presentation: Jeff Didas
This document discusses issues that can arise when pipelines and HVAC power lines are collocated within the same right of way. It describes three main types of interference between pipelines and AC power: electrostatic coupling causing nuisance effects, conductive coupling resulting in fault currents, and inductive coupling producing steady-state induced AC voltages. Mitigation of these interference effects typically involves installing grounding devices to discharge AC current away from the pipeline in order to reduce coating stress and induced voltages below safety and corrosion thresholds. Computer modeling can assess mitigation options, but has limitations due to assumptions. Field testing provides direct measurements of conditions.
2012 FEPA Presentation: Richard Musgrove
The document discusses Florida's statewide environmental resource permitting (ERP) program. It provides three purposes of the ERP program: to protect water quality, manage water quantity and flood protection, and protect wetland functions and other environmental resources. It also discusses the legislative intent of the statewide ERP rule to simplify and streamline the permitting process, increase consistency, and retain regional differences. The statewide ERP rule will consolidate the existing regional rules into a single rule and standardize permitting thresholds and criteria.
2012 FEPA Presentation: Ted Huck
This document discusses issues that can arise when pipelines and HVAC power lines are located near each other in the same right of way. It describes three main types of interference: electrostatic coupling causing nuisance voltages, conductive coupling producing high fault currents, and inductive coupling generating steady induced AC voltages. Mitigation often involves installing grounding devices to discharge currents and reduce voltages. Modeling of interference is complex, while field testing and risk assessments can also provide useful information for evaluating corrosion and safety risks from alternating currents.
2012 FEPA Presentation: Don Thorn
The document discusses safety culture in the pipeline industry, defining it as the behaviors and beliefs developed through training that result in preventing incidents, injuries, and losses. It emphasizes that safety must be a core value, not just the number one priority, and that all accidents are preventable by focusing on safe behaviors and decision making through improved training, education, and coaching of the workforce from management. The purpose is to provide methods for observing worksites to identify and correct unsafe behaviors and conditions through casual, special, and formal observations coupled with coaching employees to ensure their safety.
2012 FEPA Presentation: Danny Kilcollins
The State Emergency Operations Center (SEOC) coordinates Florida's response to emergencies and disasters. For minor emergencies, the SEOC monitors the situation with limited staff, but activates more fully for major events. The SEOC receives information, identifies resource needs, and keeps officials and partners informed. It provides direction, executes response strategies, and adjusts operations as needed. The State Watch Office within the SEOC is staffed 24/7 to communicate with counties and respond to routine issues, assessing resource needs and coordinating the initial response. Local governments own response and recovery efforts, with state and federal support when needed, such as during a 1998 natural gas pipeline explosion in Perry, Florida.
2012 FEPA Presentation: Charlie Hall
This document discusses integrity management and external corrosion direct assessment (ECDA) over a 10 year period. It provides an overview of ECDA as a 4 step process including pre-assessment, indirect inspection, direct examination, and post assessment. Congress required pipeline operators to implement integrity management programs, including conducting baseline assessments using methods like ECDA, to help prevent pipeline failures and protect public safety. ECDA aims to locate potential corrosion issues to prioritize repairs and reassess pipelines over time. The document outlines each step of ECDA and emphasizes following the full process is important for ensuring pipeline integrity.
2012 FEPA Presentation: Berne Mosley
The document summarizes Berne L. Mosley's presentation at the 23rd Annual Summer Symposium of the Florida Energy Pipeline Association on July 19, 2012. The presentation discusses trends in the natural gas pipeline industry driven by increased shale gas production, including changes in pipeline flow patterns, pending and approved pipeline projects, LNG export terminal status, and applications to export domestically produced LNG. The presentation also summarizes a DOE/EIA study finding that increased LNG exports would lead to higher domestic natural gas prices but also increased domestic production and reduced consumption.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
