The Power of Models and Modeling Essay

Models provide the physical testing and proof of a hypothesis by exploring the extent to which the two factors relate within the given hypothesis. It puts a theory into action, to see if the theory is corrected causes and effects.

Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample. The variable in this information is nitrogen concentration (mg nitrogen/l water).

A mass curve and double mass curve were created for the Red Deer basin at Drumheller in 1964. Precipitation data was collected from the city of Drumheller, which is approximately 0.6 km from the river measurement. On average the greatest amount of precipitation occurred in May, June, and July, but there was a large spike in precipitation in the month of September. The lowest amount of precipitation occurred in January, February and October. The double mass curve for this basin has a large gradual increase. Runoff for this basin is always greater than precipitation, but there is an area of large run off and storage during the end of the curve. This could be due to the large amount of precipitation that occurred in September, and storage

Background (1 ¶): What is the Duck Creek Watershed? What problems is it facing? What is being done so far to remedy these problems? Who is working on this problem?

To apply the computational methods to estimate the fate and transport of pollutants in Leon River and Navasota River watersheds of Brazos River watershed.

Relationships of rocks and their qualities are apparent ubiquitously and are comparable between Clear Creek a nearby Valley Wall. Comparability between Clear Creek and a nearby Illinois River location also display an ever-present relationship of their discharge. Through USGS, the discharge of streams and springs correlate two water types; karst development.

What is a watershed? A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. You think every creek is the same but in reality they’re not. In this essay we are comparing San Mateo and San Juan creek.

Civica will first create the model for future conditions based on the calibrated model. This will involve adding proposed ponds and changing parameter values to reflect the future developments (e.g. imperviousness and curve number).

Exercise behavior is the study of theories which work to explain actions and phenomenon’s that occur when looking at peoples perspectives of exercise. One overall theory called The Transtheoretical model (TTM), includes elements from “across a variety of theories and models behavior, some of which are social-cognitive in nature and some of which are not” (79). The TTM describes five stages of behavior change: Precontemplation, contemplation, preparation, action and maintenance. By using TTM as the base of multiple theories, a greater picture of exercise behavior is created to understand how individuals become interested and continue to make a life style that involves normal exercise.

A watershed is a land area that drains rain and other water into creeks, rivers, lakes, oceans, etc.

It is irrefutable that the formulation of the Transtheoretical Model (TTM), has efficaciously contributed to current perspectives in health psychology, allowing for a greater understanding in facilitating healthy behaviour change (Adam & White, 2003). TTM is a comprehensive six-stage theory which logically describes behaviour change as a process rather than a single event, providing the pathway to a more enduring and successful outcome (Adam & White, 2003; Prochaska, 2008). These stages include: pre-contemplation, contemplation, preparation, action and maintenance, which occur cyclically in the event of relapses, until temptation is no longer present, resulting in termination (Marshall & Biddle, 2001; Prochaska, 2008).

Decisions! Decisions! Decisions! How do you make decisions? Have you ever asked yourself, “How did I make that decision?” Whether big or small, important or not so important, decision making is a process. Some people way the pros and cons while others may just flip a coin. Are decisions based on feelings, outcomes or information? Often times if we just go with our gut feeling will be miss out on important information that should be included in our decision.
