Estimating the Spatial & Temporal Distribution of Snow Water Equivalent Within a Watershed

Abstract:-

This is Civil engineering thesis project on “Estimating the Spatial & Temporal Distribution of Snow Water Equivalent Within a Watershed” and the goal of this analysis was to develop a spatial-temporal model to forecast the snow water equivalent (SWE) inside a watershed. This model outlined the connection between the physical parameters of a watershed and therefore the spatial distribution of SWE inside that watershed. Several models of snow melt runoff accept snow depletion curves, that describe the seasonal decline of snow coated fraction and SWE, presumptuous some inter annual uniformity of basin response.

 

Estimating the Spatial & Temporal Distribution of Snow Water Equivalent Within a Watershed

 

The null hypothesis related to this analysis was that the spatial and temporal variability of SWE inside a watershed could be a random method that’s freelance of the physical characteristics of the watershed. A abstract model of spatially distributed SWE accumulation and depletion which will be label and valid with spatially distributed observations was created.

The results of the physical variables and parameters on the SWE distribution inside a watershed were incontestible, and each vital and insignificant physical variables and parameters were known. however information were employed in the calibration/validation of the model was incontestible, as well as showing the advantage of extra information on model accuracy. Finally, the right activity associate degreed validation of the model mistreatment an actual watershed was incontestible on 3 totally different watersheds.

Results of the analysis were mixed in terms of acceptive or rejecting the null hypothesis. Created SWE maps and satellite pictures of the higher river Watershed visually prompt that similar SWE patterns exist for this watershed. Associate degree analysis of the info from the SNOTEL sites inside the higher river Watershed conjointly prompt the existence of comparable interannual SWE patterns inside the watershed. This analysis supports the Depletion Curve Theory.
