Porous concrete can be used as a drainage system that allows rainfall to percolate into the ground, reduce stormwater runoff, and recharge groundwater. consists of coarse aggregate cement paste. Stone mining waste in river, namely medium-sized gravel which is often called blondos stone, has not been optimally building material. Based on these reasons, it tried use stone porous concrete. Three v...

In this paper, a planning analysis of implementing low impact development (LID) type of stormwater best management practices (BMPs) for urban runoff control is presented. The Beijing Olympic Village (BOV) residential area in China was used as a case study. The original BOV stormwater system incorporated some LID BMPs such as porous pavements, green roofs and rainwater cisterns. After the 2008 O...

Constructed Floating Wetlands (CFW) for stormwater treatment are increasingly used to treat urban runoff. However, studies of large-scale systems and the long-term evaluation of their treatment efficiency are scarce. This article presents the final results of a two-year study of the pollutant removal performance of a CFW in a stormwater pond capturing runoff from a low-residential catchment in ...

The use of decentralised, sustainable urban drainage systems (SUDS) for the treatment of stormwater runoff is becoming increasingly prevalent in Germany. Decentralised SUDS can offer a viable and attractive alternative to end of pipe treatment systems for stormwater runoff from urban areas. However, there is still some uncertainty regarding the long-term performance of SUDS, and the general leg...

Analyses of regional-scale synoptics and air-mass trajectories, local-scale atmospheric measurements (wind direction and speed, air temperature, dust load, SO 2 and NO x concentrations in the air, rain amount and intensity), and chemical and isotopic compositions of rainwater collected in the coastal city of Ashdod, Israel, were used to identify the various contributing sources to rainwater sal...

The U.S. Environmental Protection Agency (EPA) requires that stormwater be controlled to the maximum extent practicable through the use of stormwater control measures. These regulations are enforced by state and local governments, who often require the use of SCMs to comply with total maximum daily loads (TMDLs). State and local governments also provide guidance on SCM design and assign load re...

The design of three stormwater treatment facilities, aiming at implementing and demonstrating technologies that efficiently reduce diffuse urban pollutant loads onto receiving waters is presented. The designs aim at reducing not only particulates, but also dissolved pollutants and pollutants associated with colloids. Unit operations that are efficient in this respect are discussed. Different te...

Urbanization has been found to impact stormwater runoff quantity and quality. A study catchment with mixed land use, residential and industrial were investigated and the water quality discharged from the catchment were sampled and tested for four basic water quality parameters; BOD5, NH3-N, NO3-N and P. One dry weather flow and several stormwater runoff were sampled. Results were compared to th...

Estimating the spatial and temporal patterns of groundwater recharge through integrated water balance modeling plays an important role in sustainable resource management. Such effort is particularly essential for data-scarce regions, such as Rift Valley Lake basin Basement Complex Ethiopia, which has shallow aquifers, a proliferation wells, poor monitoring networks. A spatially distributed mode...

Highway stormwater runoff represents a significant source of dissolved copper to surface 4 waters. It is well established that even low concentrations of dissolved copper can be toxic to many 5 aquatic organisms. In the Pacific Northwest of the United States, recent research has focused on the 6 effects of low-level copper exposure to salmonids listed as threatened or endangered under the 7 End...
