Internal Phosphorus Loading In Spring Lake: Year 2, Dr. Alan Steinman, Dr. Rick Rediske, Mrs. Lori Nemeth

Scientific Technical Reports

Experimental and desktop studies were conducted during 2004 to better understand the factors affecting internal phosphorus (P) loading in Spring Lake, Michigan. A prior study in 2003 resulted in estimates that between 55 and 65% of the total phosphorus entering the water column of Spring Lake, on an annual basis, originated via internal loading from the sediments. The results from the current study indicated the following:

Phosphorus release rates were no different at alum concentrations of ≥ 15 mg alum/L compared to 24 mg/L. However, the higher alum concentration is likely to provide greater spatial coverage over the sediments in …

Lower Grand River Watershed Management Plan, Fishbeck, Thompson, Car & Huber, Inc.

Watershed Management Plans and Reports

A Watershed Management Plan (WMP) considers many aspects of water usage and functions, and coordinates them into a comprehensive plan for managing the activities that govern how our natural resources are utilized or viewed. A WMP is developed to provide direction and prioritize how resources are used for the management, protection, or restoration of a watershed. A watershed approach is ideal for managing water resources since they cross jurisdictions and political boundaries. Often this fluid nature of water is overlooked or taken for granted. Water flows over the ground and picks up pollutants before reaching a lake, stream, wetland, or …

State-To-State Rotational Relaxation Rate Constants For Co+Ne From Ir-Ir Double-Resonance Experiments: Comparing Theory To Experiment, David A. Hostutler, Tony C. Smith, Gordon D. Hager, George C. Mcbane, Michael C. Heaven

Peer Reviewed Articles

IR-IR double-resonance experiments were used to study the state-to-state rotational relaxation of CO with Ne as a collision partner. Rotational levels in the range J_i=2-9 were excited and collisional energy transfer of population to the levels J_f=2-8 was monitored. The resulting data set was analyzed by fitting to numerical solutions of the master equation. State-to-state rate constant matrices were generated using fitting law functions. Fitting laws based on the modifed exponential gap (MEG) and statistical power exponential gap (SPEG) models were used; the MEG model performed better than the SPEG model. A rate constant matrix was …
