Modeling the Effects of Land Use Change on FloodingAdam Nayak
Due to population growth, urban areas in Oregon have been expanding, leading to increases in impervious surfaces and net losses in wetlands, riparian vegetation, and forestation in the Northwest. Utilizing ArcGIS and NOAA’s C-CAP imagery, this study classifies and analyzes urban land use changes between 1996 and 2010. These findings shed light on the importance of land use management in urban settings and are being used by local watershed councils to advocate for changes within their stream basins.
Integration of the MODFLOW Lak7 package in the FREEWAT GIS modelling environmentMassimiliano Cannata
The MODFLOW Lake Package is integrated into the FREEWAT GIS environment in order to simulate surface water - groundwater interaction using state of the art techniques for numerical simulations, thus allowing the improved consideration of surface water bodies for water resources management. Surface water bodies, both stationary and flowing, can strongly affect groundwater elevations and flow patterns which in turn may affect the qualitative and quantitative state of groundwater resources. With the advancement of numerical simulation techniques and increased model complexity, FREEWAT facilitates the usage of the lake package through existing QGIS tools to edit model layer geometry as well as an intuitive and simple user interface for the specification of constant and time variable lake properties as defined through MODFLOW.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
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.

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.

"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.

Problem Statement: A Collaborative Effort
• SWMM – answers the questions about how Low Impact Development (LID)
strategies affect end of pipe flows
• Our challenge:
• Do LID strategies really work?
• Where do they work?
• Geology, topography, depth to water table
• How effective?
• How much water can a LID strategy handle?
• Which LID work best where
• When – temporal questions?
4. 4
The Earthfx LID Approach
• Case study: A planned development with an existing storm-water
management model used to assess the effectiveness of storm water manage
facilities in mitigating erosion in stream channels
• Additional questions were raised on the impacts development would have to
wetlands, streams, and groundwater resources
• Earthfx was then brought in from a groundwater perspective, as we had a
working groundwater model in the area
• Our solution: GSFLOW
• Fully-distributed, multi resolution, variable temporal resolution
groundwater/surface water model
• Full LID support
• High resolution prevents the lumping of parameters over large areas and
answers specific/local questions about LID function
• Overland flow scheme provided a means to communicate hydrological
processes to the existing erosion model

GSFLOW Outputs:
• Hydrographs: all flow components (baseflow, unsaturated flow, direct runoff)
• Streamflow: total flow routing, flow accumulation, groundwater discharge to
streams and wetlands
• Identifying high-volume recharge areas
• Backward particle tracking from any feature
• Topographic controls on recharge
• Swales
• Road ditches
• High recharge at geological boundaries
• Water table drawdown under land development
• LID implementation vs No LID implementation
• Feature-based waterbudgets and hydroperiod analysis
• Animations
21. 21
Low Impact Development Strategies and Development Scenarios
• Cell-based land use distribution can be utilized to assess alternate development plans
(i.e., land use changes)
• GSFLOW has the ability to account for the positioning of separate LID stores placed
on a cell-by-cell basis
• Feature based water budgets: e.g., groundwater vs. surface water component,
hydroperiod, etc.
• LID components used in GSFLOW are comparable to that of SWMM:
• Surface Layer
• Soil Layer
• Storage Layer
• Under drain/pervious redistribution
• Pavement Layer*
• Many LID strategies can be modelled:
• Porous Pavement
• Infiltration trenches and galleries
• Rain Barrels and Cisterns
• Green roofs
• Downspout disconnect
22. 22
Low Impact Development Strategies
A Case Study
• Questions were raised whether there exists an impact to wetlands, streams, and
groundwater resources due to the proposed development
• Many LID strategies were applied: green roofs, downspout disconnect, pervious
paving, bio-swales, infiltration gallery, and increase top soil depths
• Preliminary analysis demonstrated that the existing development plans would
lower the groundwater table 4.5m using a loosely-couple steady-state groundwater
model
• An infiltration gallery was used to attempt to mitigate this drawdown.
• Simulated runoff from the GSFLOW model were easily applied to the existing storm
water management model that was already in use to assess potential erosion and
storm water management facilities

Low Impact Development Strategies
Case Study Results
• Placement and effectiveness of infiltration gallery is highly dependent on geology
and depth to water table
• When compared with planned development without LID implementation, LID
strategies demonstrated significant improvements:
• reduced groundwater drawdowns by 86%
• regained groundwater discharge to streams by 42%, and
• reduced the increased runoff generated by 80%
26. 26
Conclusions and Future Directions
• Potential exists for collaborative modelling efforts to provide a holistic solution for
various stakeholders, able to answers questions such as:
• Which LID strategies work, and how well?
• Where does the positioning (and sizing) of LID mechanisms make them most
efficient?
• How does LID impact ecologically sensitive features and the sustainability of
our water resources?
• Site details are important, and they can be represented at high resolution
• Limitless scenarios can bee applied
• Impose land-use changes to elevation (need to modify topography)
• Allowing for development to occur during a continuous simulation would provide
for an impact assessment during the construction phase
