Spatial distribution of imperviousness and the space‐time variability of rainfall, runoff generation, and routing

摘要: [1] We study the relationship between spatial distribution of imperviousness and space-time variability rainfall, runoff generation, hydrologic response. For this we follow an analytical framework that is able to represent use it determine relationships for quantities commonly used in hydrology, example, amount rainfall excess, total from a storm, ratio developed land undeveloped use, mean time variance time. The are derived such runoff, response, their relative importance, can be identified compared. In addition, method allows separation pervious impervious contributions estimation influence on We illustrate available data apply them two cases. first case, its interaction with cover investigated. second examine impacts pattern relationships. find interact either increase or decrease average excess. also response depend form overall pattern. proposed useful tool identifying importance different components mixed pervious-impervious landscapes.
