Storm-Related Suspended Particulate Matter In Little Westham Creek, John R. Jordan
Storm-Related Suspended Particulate Matter In Little Westham Creek, John R. Jordan
Master's Theses
Properties of a watershed regulate the amount of suspended particulate matter (SPM) in a stream. The present study examined relationships between storm-related SPM and impervious area and tree cover in the suburban watershed of Little Westham Creek, Richmond, Virginia during Summer and early Fall, 1999. SPM concentration, SPM discharge, and turbidity due to clay, silt and sand, and the areas of impervious surface and tree stand cover in the watershed were measured at three sites. SPM concentration, SPM discharge, and turbidity due to clay were greater upstream than downstream. The percentages of watershed area covered by impervious surfaces and tree …
The Quality Of Storm Runoff From Different Kinds Of Land Surfaces In The Drainage Basin Of Westhampton Lake, Richmond, Virginia, Margaret Emil Coppedge
The Quality Of Storm Runoff From Different Kinds Of Land Surfaces In The Drainage Basin Of Westhampton Lake, Richmond, Virginia, Margaret Emil Coppedge
Master's Theses
Samples of runoff were collected during storms from four different areas within the drainage basin of Westhampton Lake, Richmond, Virginia, between October, 1977, and January, 1978. The areas were a residential area, concrete street gutter, asphalt parking lot, and broadleaf forest.
The samples were analyzed for pH, levels of reactive phosphate, nitrate, and turbidity, and their effects on the growth of algae from Westhampton Lake.
The pH of runoff from the residential area, gutter, and forest usually ranged between 6-7 and the parking lot usually ranged between 4-5. Levels of turbidity varied considerably between storms and areas. Runoff from the …
A Survey Of Fresh-Water Oligochaeta And Their Commensal Ciliates From The Richmond, Virginia Area, Elsa Queen Falls
A Survey Of Fresh-Water Oligochaeta And Their Commensal Ciliates From The Richmond, Virginia Area, Elsa Queen Falls
Master's Theses
The distribution of North American aquatic oligochaetes and the ciliates inhabiting their guts have received very limited attention. For this reason, the present study was initiated to survey fresh water oligochaetes of the families Aeolosomatidae, Naididae, Opistocystidae, and Lumbriculidae in four bodies of water of the Richmond, Virginia area and to determine the incidence of commensal ciliates within the gut .
