Modeling floodplains and surface water design at landfills – should you use 1-D or 2-D?

Everyone knows that proper delineation of floodplain limits and design of surface water management controls is an important part of any landfill design, whether it’s an initial facility siting/design or an expansion. Part of that delineation usually requires use of computer modeling of existing and proposed surface water conditions. Over the years I’ve used both…

Thoughts from GWMS – New flares with higher turndown capacity benefit LFGTE operational flexibility and solid waste impacts of shale fracking

At the last Global Waste Management Symposium, I presented on the benefits of using landfill gas to power a flare, giving the end user more operational flexibility – say for landfill gas-to-energy or other beneficial reuse systems. I offered three case studies of situations where continuous biogas pilots worked well, along with costs for implementation….
