Variability in Photosynthesis: Impact on DO Models
Publisher: American Society of Civil Engineers
Abstract: A methodology for quantifying the net contribution by algae to the oxygen resources of rivers is presented. The approach recognizes natural variation in incident light as a key factor mediating the character and magnitude ...
Calculation of Daily Average Photosynthesis
Publisher: American Society of Civil Engineers
Abstract: It is important to integrate net photosynthesis over depth and time to obtain accurate estimates of daily average net photosynthetic rates. Three different methods for calculating daily average net photosynthesis in a water ...
Partitioning Phosphorus Loads: Implications for Lake Restoration
Publisher: American Society of Civil Engineers
Abstract: An extensive tributary monitoring program was undertaken to evaluate phosphorus loads to Onondaga Lake—a hypereutrophic water body near Syracuse, New York. The resulting phosphorus budget indicates that diversion of treated ...
Determination of Reaeration Coefficients: Whole-Lake Approach
Publisher: American Society of Civil Engineers
Abstract: Onondaga Lake, N.Y., experiences a marked annual dissolved oxygen depletion over the entire water column at fall turnover. Depletion occurs as a result of the entrainment of reduced substances that have accumulated in the ...
Optimal Cost Control Strategies for Attached Algae
Publisher: American Society of Civil Engineers
Abstract: This paper presents a cost‐benefit analysis for alternative programs intended for the control of the nuisance growth of an attached alga
Dual Discharge Approach to Accessing Assimilative Capacity: Probabilistic Analysis and Management Application
Publisher: American Society of Civil Engineers
Abstract: A dual discharge strategy has been proposed for management of the effluent from the Syracuse Metropolitan Treatment Plant (Metro). The approach involves routing the discharge to the Seneca River when assimilative capacity ...
Sed2K: Modeling Lake Sediment Diagenesis in a Management Context
Publisher: American Society of Civil Engineers
Abstract: The development of a vertically-segmented, mechanistic mass balance model (Sed2K) for particulate organic matter (POM) diagenesis in lake sediments is described. The model is parsimonious in its requirements for input data ...
Validation of Water-Quality Model for Seneca River, N.Y.
Publisher: American Society of Civil Engineers
Abstract: The validation of a water-quality model for the Seneca River, a deep, stratifying, slow-moving river located in central New York, is documented. Model validation is supported by comprehensive field monitoring and kinetic ...
Modeling Effects of Sediment Diagenesis on Recovery of Hypolimnetic Oxygen
Publisher: American Society of Civil Engineers
Abstract: Diagenesis of particulate organic matter in sediments can have important effects on the dissolved oxygen (DO) resources of lakes and delay potential benefits from reductions in phosphorus (P) loading. A sediment diagenesis ...
Accessing Assimilative Capacity through a Dual Discharge Approach
Publisher: American Society of Civil Engineers
Abstract: The historical development of environmental stressors in the watershed of Onondaga Lake (N.Y.) and the adjoining Seneca River is outlined as a prelude to the presentation of a novel approach for accessing assimilative ...
