Geology of kilgard Creek: As with many geographic features it is geology that determines the behaviour and rate of change the stream can have or cause. The mineral hardness, or variety of the bedrock, and type of soil determine the erosion rates, sediment constitution and ultimately dictates the shape, grade and chemistry of a stream. Often one can determine the geologic constituents of an area by examining the stream bed and types of rocks it includes, however, snce Kilgard creek parallels a well-traveled road, most of the interesting rocks have been imported by road crews to ensure the stability of the bank and side slopes. The velocity of stream water determines how much sediment and the size of sediment a stream can carry, this quantity is called 'load' and streams with high load capability have devastating erosion potential. kilgard creek was found to have a velocity of      , and a discharge or       , which is a relatively insignificant erosion hazard. The size of rocks found in a stream bed often indicate what sort of discharge extremes a creek is capable of. At Kilgard, the rocks ranged in size from sand to boulder with the majority being cobble sized rocks. The percent coverage was found to be between 10 and 25% and the embeddedness was varied in that there was sections in slow moving eddies where there was a large amount of sediment cover, however in the faster moving water the rocks were mainly large cobble with little to no embeddedness. As one see the geologic component effects many physical factors of a stream, such as fluid dynamics or the 'load' capacity of the stream.
