Book Description
A single linear reservoir (SLR) model is presented which provides a simple means for developing runoff hydrographs for small, urban watersheds. The model only requires one parameter, K, which can be estimated from watershed and precipitation characteristics. Several methods for estimating K and the results of testing the model on various watersheds are presented. (Author).

Book Description
This paper overviews the general features of computer program 'HEC-5, Simulation of Flood Control and Conservation Systems', with emphasis on the capabilities of the most recent release of HEC-5, Version 7.2, dated March 1991. HEC-5 can simulate the essential features and operation goals and constraints of simple or complex systems with simulation intervals ranging from minutes to one month. Single event flood analysis and period of record conservation analysis may be accomplished with the model. Flood control analysis includes balanced system operation for downstream damage centers with consideration of forecasted local flows and hydrologic routing. In addition, induced surcharge operation based on spillway gate regulation schedules can be simulated. Hydropower analysis may include run-of-river, peaking, and pumped storage plants as well as system power operation. Water supply simulation can include reservoir and downstream flow requirements in addition to divers ions and return flows. Water Quality analysis can include simulation of temperature, dissolved oxygen, up to three conservative and up to three nonconservative constituents. Computer Programs, Simulation, Reservoirs, Flood Control, Reservoir Yield, Hydroelectric Power, Water Supply, Water Quality.

Book Description
Values have recently been recognized as a variable that may aid in explaining food behaviour. Further, values are being increasingly considered by nutrition educators as a factor which may affect an individual's participation in educational programmes and his/her adoption of beliefs related to the programme. A group of 50 independent-living individuals over 59 years of age participated in a study designed to measure, and determine the relationships between, food-related value-orientations and diet quality. Research instruments included a questionnaire with 55 value-orientation statements and 7 demographic questions, and a 3-day food record. Years of education and former occupation prestige were combined as an index of socio-economic status. There was agreement (p=0.01) among the seniors as to the hierarchal ranking of the 7 value-orientation scales (-=0.70 to 0.87) derived from the value-orientation statements. Familism was ranked higher, and religion ranked lower, than health, education, economics, convenience, and social-psychological uses (p=0.05). Guttman scalogram techniques were applied to develop a 7-step scale of diet quality (C.R. = 0.93; C.S. = 0.66) following comparison of mean food group intake to that recommended by Canada's Food Guide (revised 1977). While 96 percent of the subjects reached step 2 (bread and cereals), only 6 percent reached step 7 (milk and milk products). Neither the hierarchal ranking pattern of value-orientations nor the scoring of individual value-orientations were related to diet quality. Socio-economic status level was negatively related to the value-orientations education, economics (p=0.01), and religion (p=0.05). Concomitant study of attitudes, beliefs, knowledge, values, and demographic factors is necessary to more fully understand the interaction of these variables in relation to the food consumption decision.
