本研究的目的是提出一个分布式水文模型，特别是专门用于城市集水区，并能够代表水文过程中通常被忽视的城市建模，如蒸散，渗透在道路上，或直接渗透的土壤水在下水道。这个模型，被称为城市径流分支结构（URBS）的分布考虑到土地利用的空间变异性，这是众所周知的，由于城市数据库管理的GIS。生产函数在每个地籍地块尺度上都有详细说明，产生的径流通过一个简单的传递函数进行路由。该模型的输入参数的估计主要是基于物理的考虑，该模型被应用于郊区集水区在南特（法国），以评估的利益的水文变量的分布。
The objective of this study is to present a distributed hydrological model especially dedicated to urban catchments, and able to represent hydrological processes usually neglected in urban modelling, such as evapotranspiration, infiltration in roads, or direct infiltration of soil water in sewers. This model, called URBS (as Urban Runoff Branching Structure) is distributed considering the spatial variability of land use which is well known thanks to urban databanks managed by GIS. The production function is detailed at each cadastral parcel scale, and the runoff produced is routed by a simple transfer function. The estimation of the input parameters of the model is mostly based on physical considerations, and the model is applied on a suburban catchment in Nantes (France) in order to evaluate the interest of the distribution of the hydrological variables.
