International Projects

Lynker has worked with many international clients over the years on interesting climate topics. Lynker staff serve in a variety of roles in this field. Inter-American Development Bank, Climate Change Technical Lead, climate change impacts in central America, Inter-American Development Bank (IADB, 2014-2015). Developed climate change scenarios for future precipitation extremes to help IADB quantify […]

Citizen Science Initiative on the Yakima River

While directing a watershed science research team (RGIS-CSI Pacific Northwest) at Central Washington University (CWU), Lynker’s Graeme Aggett won a USDA-CSREES grant to develop a citizen science initiative on the Yakima River to gain better understanding of the impacts of agricultural use and master-plan development land use changes on a reach of the Yakima River, […]

Design for Restoration of James Creek between Jamestown and Left Hand Creek Confluence

Lynker, working with a team comprised of Otak, Ecos and Amec, developed a 30% stream restoration design for James Creek that supported a CDBG-DR implementation funding application and provided clear direction for detailed engineering and specifications. Lynker developed a conceptual model that describes and illustrates past, present and potential future conditions of the study sites […]

Lefthand Creek Watershed Master Plan

Lynker developed a watershed master plan to serve as a road map for rebuilding roads and bridges in the Left Hand Creek watershed, restoring the stream and protecting against future flood events. The plan included conceptual-level designs to illustrate recommendations for different river styles including headwater, confined valley with bedrock controlled floodplain pockets, limited floodplain, […]

Llandegfedd Reservoir Optimization

Llandegfedd Reservoir is an off-channel reservoir operated by Welsh Water, located in Wales, United Kingdom. The reservoir is filled by pumping from the nearby River Usk and was operated to maintain full storage throughout the year, to maximize water supply availability. However, Welsh Water was interested in changing the reservoir operating rules to allow for […]

Carlsbad Hydrologic Unit – Lagoon TMDL Monitoring

A monitoring program was developed for the quantification of phosphorus, nitrogen, chlorophyll-a, sediment, and bacteria within four lagoons located in the Carlsbad hydrologic unit in San Diego County. Water quality samples were collected throughout the duration of the one year monitoring period during dry weather conditions as well as wet weather storm events to accurately […]

Statistical Modeling to Study Climate Change Impacts on Municipal Stormwater Intensities

Lynker conducted modeling using the R statistical language to evaluate the effect of climate change on the Intensity-Duration-Frequency (IDF) curves used by Prince Edward Island to assess their municipal stormwater system.  Lynker obtained data and correlated specific climate variables with recorded storm intensities.  Once the ideal variables were selected, future projections of these variables from […]

Development of Synthetic Hydrologic Records for Modeling Shasta Temperature Management

Lynker was tasked with developing synthetic streamflow records to be used for input to the National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service (NMFS) Winter-run Life Cycle Model (WRLCM). A synthetic record of annual flow for the Sacramento River Index is needed for this application in order to construct a hydrology dataset that […]

Colorado Decision Support Systems

Lynker staff have completed a number of contracts related to the development and implementation of decision support systems for the State of Colorado’s Water Conservation Board (CWCB). Among these efforts are the 1) Water Rights Model of Colorado Water District 6 for the South Platte DSS, a DSS component that captures the hundreds of water […]

Lynker creates the Future Avoided Cost Explorer: Colorado Hazards (FACE:Hazards)

In the past two decades, Colorado has experienced wildfires, sustained droughts, and intense flood events – natural hazards that have had significant impacts on the Colorado economy. The State of Colorado recognizes that these hazards can be exacerbated as climate change intensifies the severity of events, and a growing population puts more people into harm’s […]
