Stormwater remains the sole source of aquifer recharge in Gaza strip, which should be utilized properly through artificial infiltration. The study objective is to investigate and analyze infiltration efficiency three large exiting basins strip (Alamal, Asadaqa, Waqf) using different techniques. technique applied Ala-mal basin natural surface spreading stormwater while Asadaqa used combined with...

As stormwater flows are intermittent, the requirement to store urban runoff is important to the design of a stormwater re-use scheme. In many urban areas, the space available to provide storage is limited and thus the need to optimise the storage volume becomes critical. This paper will discuss the advantages and disadvantages of two different approaches of providing storage: 1) a single storag...

The contribution of atmospheric deposition to emissions of trace metals in stormwater runoff was investigated by quantifying wet and dry deposition fluxes and stormwater discharges within a small, highly impervious urban catchment in Los Angeles. At the beginning of the dry season in spring 2003, dry deposition measurements of chromium, copper, lead, nickel, and zinc were made monthly for 1 yea...

Pollution from highway stormwater runoff has been an increasing area of concern. Many structural Best Management Practices (BMPs) have been implemented for stormwater treatment and management. One challenge for these BMPs is to sample stormwater and monitor BMP performance. The main objective of this study was to evaluate the feasibility of using polyurethane foam (PUF) passive samplers (PSs) f...

Stormwater management has significant consequences for urban hydrology, water quality, and flood risk, and has changed substantially over history, but it is unknown how these paradigm shifts play out at the local scale and whether local changes in stormwater infrastructure use follow similar trajectories across cities. This research addressed: (1) How does current infrastructure use and past in...

Infiltration of stormwater through green surfaces is an important means groundwater recharge. However, the increase in constructed impervious area caused by intensive urbanization has led to a reduction rainwater infiltration over past decade. The rapid system (CRIS) with ample open space plays role This study aims explore influence (roof runoff) concentration on table and quality CRIS. Groundw...

Understanding the complexity of dissolved organic matter (DOM) in stormwater has drawn a lot of interest, since DOM from stormwater causes not only environmental impacts, but also worsens downstream aquatic quality associated with water supply and treatability. This study introduced and employed high-performance size exclusion chromatography (HPSEC) coupled with an ultraviolet-visible (UV-vis) ...

There is the need to re-configure current urban water systems to achieve the objective of sustainable water sensitive cities. Stormwater represents a valuable alternative urban water source to reduce pressure on fresh water resources, and to mitigate the environmental impact of urban stormwater runoff. The selection of suitable urban stormwater harvesting sites is generally based on the judgeme...

For stormwater harvesting to achieve its full potential in mitigating water scarcity problems and restoring stream health, it is necessary to evaluate the human and environmental health risks and benefits associated with it. Stormwater harbors large amounts of pollutants and has traditionally been viewed as a leading cause of water-quality degradation of receivingwaters. Harvesting stormwater f...

Stormwater management has traditionally focused on the use of conveyances to quickly move stormwater runoff from urban centers into nearby rivers, streams, and lakes. The increased flow caused by impervious surface cover (ISC) leads to runoff rates that are amplified by kinematic processes as they travel through the municipality’s stormwater system. Elevated runoff volumes and rates lead to hig...
