The experiment was organized as a block design with four replications of each land use treatment.
The human activities have significantly changed the distribution and quantities of each land cover types in surrounding of Plastiras reservoir.
To assess ecosystem composition we used ArcGIS 10.0 to measure the percent area and the total area of each land cover type.
Within each climatic zone, the volumetric WY for each land cover type was highly dependent on its area of each land cover.
Chambers and EC measurements were combined to provide estimates of the continuous contributions of each land cover to the total methane emissions of the wetland.
Combining the area of each land use in the small watershed, the SDR of 0.40 is obtained in the past four decades.
Then, the LCLU maps were integrated with basic grid cell data to represent the proportion of each land cover category within a grid cell area.
We examined the difference in hydrological properties between the catchments using the non-parametric Firedman test, and differentiated the role of each land use in governing watershed hydrology using a numerical analysis technique.
Finally, the indices of the contribution to UHI intensity (CUHII) were constructed and calculated to quantify the effects of each land use change trajectory on the UHI during urbanization.
It was observed that while the hydrological response of the catchment was sensitive to the percentage of each land use type, the sedimentary response was more dependent on the spatial distribution of land use.
Thus, for such a grid-based urban hydrological model, the estimation of the Impervious Area Ratio (IAR) of each land use classification is a crucial factor for accurate runoff analysis in urban watersheds.
