This webinar will showcase three successful EPA Prize Competitions, discuss their results, and share opportunities to get involved. 111-358), EPA has conducted over 40 prize competitions that benefit the federal government by allowing agencies to, (a) pay only for success, (b) shift technological and other risks to prize participants, (c) increase the number and diversity of participants, (d) stimulate private-sector investment and maximize the return on taxpayer dollars, and (e) inspire the public to help tackle scientific, technical, and societal problems. Since the passage of the America COMPETES Reauthorization Act of 2010 (P.L. Prize Competitions are a powerful tool that can spur and democratize innovation and identify cost-effective solutions faster than traditional approaches. How can EPA make use of prize competitions and crowdsourcing to improve environmental outcomes? By tapping into the ingenuity and creativity of crowds, EPA’s Challenges and Prizes program uses the power of the public to develop tools and find solutions to pressing environmental problems. Register for the Opportunity for Prize Competitions at EPA webinar! JanuWebinar The Opportunity for Prize Competitions at EPA Webinar dates and topics are subject to change. Closed-captioned recordings of the webinars are provided below for later viewing and as a training resource certificates cannot be provided for viewing webinar recordings. Acceptance of certificates is contingent on organization requirements-EPA cannot guarantee acceptance. NOTE: Attendees have the option of receiving a certificate of attendance. In addition, the EPA Tools and Resources Training Webinar Series provides in-depth overviews and step-by-step tutorials on popular EPA science-based models and tools.
#Water quality modeling in mike 21 series
In the high water period, about 70% of the pollution ejected in the lake was automatically flushed out in the lake the Atlantic Ocean.Free webinars typically held the third Wednesday of every month from 3:00-4:00 PM (ET).ĮPA's Office of Research and Development (ORD) hosts this monthly public webinar series to translate EPA research and share research resources and information that are useful, practical/applied and available to meet research needs of states/territories and other entities, such as tribes, local governments, and communities. In this period tidal flushing evacuated about 20% of the pollution ejected. This accumulation increases in amplitude as one moves away from the Atlantic Ocean towards the north of the lake. Simulation of the dispersion of nutrient point source pollution indicated that there was an accumulation of pollution at the bottom of the lake during low water periods. During flooding, despite the large inflow of fresh water, more than 60% of the water at the bottom of the lake had concentrations greater than 8. Water quality simulations indicated that the seawater intrusion from the Atlantic Ocean into Lake Nokoué occurred from the bottom to the surface towards the surface of the lake. The water level in the delta showed a water increase of 0.6 m, in seven days, for a water flow of 725 m3/s at Bonou and a water increase of 1.3 m, in seven days, for a water flow of 1100 m3/s at Bonou. 70% of the land in the delta of Ouémé, between the Ouémé River and the So River (also a tributary of Lake Nokoué), are flooded against 90% for a river flow of 1100 m3/s. The results from the HD simulation indicated that for a flow of 725 m3/s at Bonou on the Ouémé River, a tributary of Lake Nokoué. The data used covered the hydrological period of 2013. The Hydrodynamics (HD) module simulated water level variations and flows in response, while the ECO-Lab module has been used for water quality modelling. The choice of the Mike 21 was motivated by the long practice that decision-makers in Benin have with this software.
To understand the salinity dynamic at the outlet of Lake Nokoué and to simulate the nutrient flushing from this lake into the Atlantic Ocean, a 2D hydrodynamic model was designed with Mike 21.
