Ecohydrology. 2017;10:e1813. https://doi.org/10.1002/eco.1813 Abstract The use of green infrastructure for reducing stormwater runoff is increasingly common. One under‐studied component of the green infrastructure network is the urban forest system. Trees can play an important role as the “first line of defense” for restoring more natural hydrologic regimes in urban watersheds by intercepting r...

one of the most important problems in schematization and watershed management is determining the watershed measures impacts on flow distribution. flow distribution algorithms grouped into two main types include single flow direction (sfd) algorithm and multiple flow direction (mfd) algorithms. in many package of gis use the single flow direction to runoff routing. in this research studied water...

Stormwater management using water sensitive urban design is expected to be part of future drainage systems. This paper aims to model the combination of local retention units, such as soakaways, with subsurface detention units. Soakaways are employed to reduce (by storage and infiltration) peak and volume stormwater runoff; however, large retention volumes are required for a significant peak red...

Stormwater source control regulations are rapidly diffusing in many countries. Most of these are provisions that limit runoff rates at the parcel-scale, although some references indicate some negative side effects, at the catchment-scale, for this form of regulation. In this paper, we compare, at that scale, the effects of several runoff rate and runoff volume provisions, using a hydrological m...

Uncontrolled urbanization is a frequent cause behind the local flooding of catchment areas. This also results in degradation water quality receivers, as well causing disruption natural cycle catchment. Classical solutions, such retention, do not prove to be sufficient under all conditions. An alternative solution application low impact development (LID), which, analysed case, takes form rain ga...

The rational method is derived as a special case of kinematic wave flow. The definition of runoff coefficient is expanded from the flow-based ratio into volume-based ratio between the volumes under runoff hydrograph and rainfall hyetograph. The new method presented in this paper provides a dimensionless approach to theoretically derive the runoff coefficients for both the conventional two-flow ...

There have been many studies of hydrologic processes and scale. However, some researchers have found that predictions from hydrologic models may not be improved by attempting to incorporate the understanding of these processes into hydrologic models. This paper quantifies the effect of simplifying watershed geometry and averaging the parameter values on simulations generated using the KINEROS2 ...

Emerging technologies of remote sensing and GIS were integrated to estimate runoff for watershed basins in China Taipei and Florida. Two basins were selected in each region, with each pair representing a static and a developing case. Remotely sensed images from the Landsat 4, 5, and 7 satellites were used to develop land cover maps of the study areas for the years 1990, 1995, and 2000. GIS anal...
