Bioswales are a naturally inspired alternative to manage stormwater and runoff from roads and parking lots. The bioswale is a vegetated ditch, trench, or plant bed that absorbs roadway pollutants and oils using plant vegetation. This allows for a decreased runoff and less harmful effluent to be sent downstream to be treated further. This project investigated what they are and how one could be integrated into Clemson's campus. This project increased my passion for using natural systems to accomplish a known goal and my collaboration skills and ability as a presenter. I could better pinpoint an issue and apply my knowledge gained in research and completing this project.

The presentation will provide an overview of each of the bayous and stream and river systems including the issues that are particular to each of them as well as a discussion of the upcoming bond issue and a discussion of key upcoming issues.

City of Houston: Beyond Recovery

juliekannai

Richard Vella, City of Houston Peter McStravick, Houston First Tom Smith and Hussein Moussa, ARUP Houston’s history has included several storm events, including Allison, Ike, Rita and most recently Harvey. Harvey’s record breaking rains resulted in flooding that became an inevitable reality. Now, Houston has made the conscience decision to build back in a more resilient way, thereby minimizing damages in subsequent events. Recovery and restoration efforts were aided by the lessons learned during these previous events. This panel session will feature representatives from City of Houston and Houston First describing how they rebuilt and restored their building operations following the Harvey storm. Those discussions will be expanded to highlight some of the key design and planning considerations that will be adopted moving ahead with this work.

Washington DC has developed a city-wide Climate Plan to address resiliency issues; speakers will describe the process of creating the plan, and how well it is working more than a year after it was implemented.

An Urban Bayou Education

juliekannai

Michelle Old, Kirksey Architecture and Scott McCready, SWA Landscape Architecture This session will take a look at the multi-faceted design approach to education carried out by the newest UHD campus addition. The University of Houston Downtown Sciences and Technology building not only provides an opportunity of formal education, but the design of the building also lends itself to an educational experience for both students and faculty alike. Throughout the project, educational and sustainable moments are showcased within the design, allowing the program to practice what it teaches. The site is designed to react to the flood plain by the use of paving quantities and site location, and a resilient landscape is achieved through the use of native plants as well as a water filtration system that is made of existing recycled concrete. Through the project, water flow can be traced from the building, through the site and ultimately into the bayou. The school’s program ties into the design by using native plants as learning opportunities as well as educational graphics that are located throughout the project. As a downtown campus, the building is connected to the existing hike and bike trail adjacent to the bayou, as well as the downtown urban edge along Main Street. This location enhances pedestrian activity through the project’s site and increases health and wellness.

Preparing for a Black Swan: Planning and Programming for Risk Mitigation in E...

juliekannai

Scott Tucker and Verrick Walker, Page A Black Swan is an event that appears random, is extremely difficult to predict, and usually occurs unexpectedly—with a huge impact. The flooding from Hurricane Harvey in 2017 was Houston’s Black Swan. Unfortunately, we seldom think of disastrous flooding in our commercial buildings, bioterrorism in our health care facilities, blasts in our mission critical facilities, or wildfires overcoming our civic infrastructure, until another black swan dominates the news. Over the past two decades, Page has formally helped owners and operators of critical facilities and infrastructure to plan and organize programs to harden and protect assets from a wide range of common and not-so-common threats, both natural and artificial. Beginning in 2001, we implemented a flood mitigation solution for Baylor College of Medicine’s campus in the Texas Medical Center after Tropical Storm Allison. Since that first project, we have helped academic, corporate, and government clients safeguard their facilities against fires, hurricanes, earthquakes, explosions, terrorist attacks, and even nuclear detonations. Through our work, we have developed a useful analytical framework for exploring resilient design options that applies to all types of threats, responses, and recovery efforts. This approach focuses on planning and programming for system-wide robustness, based on generalizing threats to buildings, rather than using actuarial data or calculated risk analysis. This presentation outlines a practical methodology for architects to evaluate facility vulnerabilities throughout the programming and design phases. We will share our threat matrix, a tool developed to summarize and prioritize risks, case studies of how we have implemented this process, and the resulting robust solutions. We also will discuss operational steps that can be taken before, during, and after extreme events in conjunction with designed solutions to maximize resilience.

Game of Floods

juliekannai

Alex Westhoff, Marin County Department of Public Works Role-playing time! Marin County’s "Game of Floods" is a fun, engaging activity to help officials and citizens confront the complexities and challenges of adapting to Sea Level Rise. The simulated, fictitious island game board addresses nature-based protections, building retrofits, land use policy changes, and traditional engineering to solve for future sea level rise. Marin County developed the Game because an educated citizenry is critical to successful planning and implementation. This small group activity involves 4-6 participants tasked with developing a vision for the hypothetical island landscape that highlights conditions that will be experienced in coming years with sea level rise and increased storm impacts causing the loss or deterioration of homes, community facilities, roads, beaches, wetlands, and other resources.

Nine Natives

juliekannai

Jaime Gonzales, the Nature Conservancy, and Beth Clark, Clark Condon Landscape Architects The Coastal Prairie Partnership, Katy Prairie Conservancy, Houston Native Prairie Association of Texas, and Clark Condon Associates came together to introduce a simple palette of native plants that is commercially available for the community to use in their landscapes. The Nine Natives were selected to work together to give a beautiful show in the garden throughout the year. Species were selected for their extended or repeat blooms, interesting foliage, contrasting colors and textures. All were chosen for the benefit to butterflies, hummingbirds, birds, beneficial insects and other wildlife in the garden and ethnobotanical value. The program includes example plans for formal and informal home gardens and street median plantings and a plan to demonstrate a multi-speciesplanting to create a native pocket prairie. While some species are strong enough in monoculture, others may be more effective in mixed groupings. The Nine Natives were judged to be a collection that would be appealing to local gardeners - easy to grow - and with a height and habit acceptable to the residential garden or street median. Most of the species are available through local specialty growers, if not local nurseries. The collection is a mix of grasses and forbs, perennials, or re-seeding annuals. Some flowers may give a quick show of brilliant color and others may carry the show throughout spring into the summer and fall long enough to contrast with the soft bloom and foliage of the native grasses in the palette. These Nine Native species may be used to incorporate natives in lieu of, or in addition to, horticultural (non-native) species. Used individually, planted in landscape beds in groups, or mixed together to make a prairie - no matter how they are used - these Nine Natives will add to the beauty and enjoyment of our gardens and neighborhoods.

Economic Resilience in the Houston Galveston Region

juliekannai

Joshua Owens, Houston-Galveston Area Council Economic resilience is the ability to prevent and withstand disruptions to the economy. The most common types of disruptions include downturns in economy or in a key industry; the closure or exit of a major employer; and natural or manmade disasters. Creating a resilient economy requires the ability to anticipate risk, evaluate how risk can impact economic assets, and building the capacity respond to disruptions. The Houston-Galveston region has one of the most robust economies in the nation with major economic assets including the energy, agriculture and medical industries; international ports; and new plant expansions. The region is also vulnerable to wide range of natural hazards, including flooding, tornadoes, tropical storms and hurricanes; as well as potential manmade threats such as chemical releases. Local economies throughout the region can be impacted by a downturn in major industries or the loss of important employers. By identifying potential economic disruptions in the region, and conceptualizing economic resilience, creates the means to enhance the region’s economic resilience, through developing a vision for resilient regional economy.

Communicating Flood Risk Using Esri Story Maps

juliekannai

Bradley Dean, Coastal Scientist, Michael Baker International Communicating about flood risk and hazard mitigation is challenging and requires storytelling. Our brains are wired to discount facts and the future. During this session, Coastal Scientist Bradley Dean CFM, CE, will explore three use cases for story maps focusing on best practices for communicating flood risk and mitigation initiatives: • Annapolis, Maryland needed a platform where residents and stakeholders could visualize and interpret the city’s flood mitigation efforts. • FEMA’s Cooperating Technical Partners’ Recognition Program wanted to showcase award recipients, San Antonio River Authority and Illinois State Water Survey, for their outstanding efforts in a unique way. • FEMA’s Risk MAP Program needed to increase awareness of non-regulatory flood risk products and their associated benefits for a broader audience. The solution was to develop story maps which utilize maps, narrative text, and multimedia content to increase accessibility and engage their target audiences. The applications are designed to be attractive and usable by anyone, which makes them great for education and outreach, either to the general public or to a specific audience. Story maps are an excellent resource to increase local awareness of current and future flood risk and interpret, prioritize, integrate, and implement solutions that reduce risk to enhance community resilience.

Promoting Resilient Communities with the SITES Rating System

juliekannai

Danielle Pieranunzi, SITES Program Specialist, GBCI Too often, landscapes are seen as an afterthought – something to be altered and shaped once elements like buildings and roads are finalized. Modeled originally after LEED, the SITES program has shifted the focus beyond the building to reveal the necessity of healthy, functioning landscapes and green infrastructure in achieving overall sustainability and community resilience. High-performance sites provide a variety of benefits and can create ecologically resilient places better able to withstand and recover from catastrophic events. This session will frame the importance of land design and development by exploring the SITES v2 Rating System and relevant case studies.

Post Harvey Flood Data and the Future of Resilient Infrastructure

juliekannai

John Blount, Harris County Engineer In late August, a downgraded tropical storm Harvey, which made landfall as a category 4 hurricane just days before, stalled over southwest Texas causing torrential flooding throughout the region. Unincorporated Harris County alone was inundated with in excess of a trillions gallons of storm water over 4 days, enough to fill the Astrodome 3200 times. In the aftermath of the unprecedented event, local officials were left to shepherd constituents through recovery and back to a sense of normalcy. In this presentation, the county engineer, John Blount, gives a detailed account of the after events of Hurricane Harvey and its effects on the environment, infrastructure and community. Mr. Blount will analyze flood data yet to be released to the public, in order give the audience a perspective of just how devastating Harvey’s flood waters were. This session will breaks down the county facilities destroyed by Hurricane Harvey and John’s vision to respond with resilient solutions instead of temporary fixes because with the frequency and severity of recent storms, this could be the new normal.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...

MMariSelvam4

The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet. Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies. By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet. In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Open Access Research Paper

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

JulietMogola

Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
