To assess these changes over time remotely sensed imagery, mapping data as well as running HEC-GeoHMS for the years under study will be used. To determine how changes in land cover have impacted both the hydrological characteristics and the 2-year and 100-year discharge events through the use of remotely sensed images, historical map data as well as the HEC-GeoHMS models will be analyzed over the past 70 years. Changes will be assessed for each of the years 1934, 1954/55, 1965, 1979, 1995 and 2002. The main focus is the changes in land cover within the region of Coyle Creek as well as the changes in the 2-year and the 100-year drainage events. In order to complete this analysis on the change in characteristics of Coyle Creek many tools must be used. Geo-referenced air photos for all corresponding years will be used to identify the changes in land cover surrounding Coyle Creek and these will be displayed on a mosaic to detail these changes. Supervised classification of these air photos’ will be used to better detail how certain features within this area have changed. Using ESRI’s ArcGIS technology as well as AutoDesk’s AutoCAD technology a 3D model will be created for a better understanding of the dynamics of the Creek basin. Further, the HEC-GeoHMS models will be compared to the 3D model created using the data. Soils mapping will be integrated within the Geodatabase to display the soil types and characteristics that surround the Coyle Creek Watershed, establishing assessments throughout the data analysis. Running the US Army Corps of Engineering HEC-GeoHMS models scenarios for the 2-year and 100-year drainage events will also indicate how they have changed from year to year as well as changes in soil and hydrological characteristics. Potential risks may be technical problems, data compatibility issues, and trivial data. June 14th, 2010 has been set as the project completion date with the project commencing on January 11, 2010. The deliverables are broken down into milestones which are to be completed as follows: Milestone 1-March 7th, 2010, Milestone 2-March 29th, 2010, Milestone 3-April 21st, 2010 and Milestone 4- June 14th, 2010. The estimated cost for this project to be completed is $52,985.63 which includes labour at a rate of $75/h, physical resource costs as well as a 10% ($4,587.50) for any margin of error that may occur.

Stream banks are typically defined by the 2-year return frequency flow event, while the stream valley is defined by the 100-year return frequency event. Runoff will thus be a function of the soils, slopes and land cover within the watershed. Streams such as Coyle Creek within the Niagara Peninsula, have experienced much change within their tributary watersheds since human activities such as agriculture and urbanization have commenced. This change has most certainly manifested itself as a temporal change in flows within the stream channel. The main problem is determining to what extent human activities such as agriculture and urbanization have affect the 2-year and 100- year flow (see appendix 4). In turn causing changes to the soil characteristics, hydrological characteristics and flow characteristics of Coyle Creek. 1.2 Scope In order to reach the project goal which is to determine how human impacts, such as agriculture and urbanization have affected the 2-year and 100-year flow events and ultimately the stream morphology of Coyle Creek, certain tasks must be completed. These task consist of creating historical air photo mosaics for Coyle Creek (tributary to the Welland River) for 1934, 1954/55, 1965, 1978, 1995 and 2002, Undertaking an appropriate
