TREE ROOT ENCROACHMENT ON LEVEE DRAINAGE SYSTEM
… were to estimate the influence of roots on the drainage facilities associated with the levees along the middle Rio Grande (MRG), and to suggest an appropriate drainage design. This study consists of three research elements: (1) GIS-based analysis in estimating root distribution along levees, (2) …

Correlation of laboratory and installed drainage system solid transport measurements
… transport of solids in 'horizontal' above ground drainage pipes was the subject of an investigation, based upon the measurement of both sterile 'model' solid velocity and 'live' waste load velocity, aimed at the establishment of a sound basis for the development of a comprehensive empirical …

Development of DRAINMOD-based VBA model for evaluating drainage system response
… that incorporates climatological data, crop drainage requirements and drainage theory into a viable design procedure. The design of subsurface drainage systems is affected by climatic variables such as temperature and precipitation. Climatic conditions are likely to change in the coming …

Modelling the subglacial drainage system of Petermann Glacier, north-west Greenland
… can raise the pressure in the subglacial drainage system as meltwater input increases and the system fails to efficiently evacuate it. Some studies suggest that increased temperatures and meltwater input will slow glaciers down by causing earlier channelization, allowing stable conduit …

Evaluation of sewer leakage into the stormwater drainage system in Singapore
… source of fecal contamination in the stormwater drainage system in Singapore. A two-step study was designed and implemented. First, water samples were collected from the downstream reaches of the stormwater drainage system to the upstream reaches in two high-density residential neighborhoods: Toa …

Biofilms as sources of fecal bacteria contamination in the stormwater drainage system in Singapore
… originating from within the stormwater drainage system in Singapore. The extent of fecal bacteria presence in storm drain biofilms was evaluated as a pathway for fecal bacteria contamination. In the research, biofilms were evaluated as reservoirs for fecal indicator bacteria (FIB), FIB …

Understanding uplift of the Ethiopian Plateau from longitudinal profile analysis of the Blue Nile drainage system
<p>The Ethiopian Plateau is one of the few tectonically-active regions on Earth that is situated in continental rift zones. About 1.6 km deep gorge of the Nile was carved by the Blue Nile River on the Ethiopian Plateau, as the plateau has been experiencing continuous uplift and exhumation in the …

The critical success factors for landscape management of operations on sustainable urban drainage system (SuDS) projects
… management, referred to as Sustainable Urban Drainage Systems (SuDS), which describes a strategic sustainable approach to the management of stormwater quality and quantity. Various typologies are used individually or in configurations to form a treatment train with engineered and landscape …

An investigation of leaky sewers as a source of fecal contamination in the stormwater drainage system in Singapore
… sewer lines in Singapore. The island's drainage channels flow into catchment reservoirs that are used to store water for future supply needs. Singapore's Public Utilities Board wishes to open up the reservoirs for recreational purposes and requires the water quality in the reservoirs to …

Inferring subglacial hydrology from investigations of supraglacial lake drainages and meltwater plumes at Store Glacier, West Greenland
… Tidewater glaciers each have unique subglacial drainage systems and discharge meltwater into adjacent fjords differently. However, studies of the subglacial hydrology of individual tidewater glaciers have been limited, largely due to the difficulty in obtaining direct measurements. The input of …

Urban hydrological modeling of the Malden River using the Storm Water Management Model (SWMM)
… which has degraded the water quality and ecosystem of the River. Following years of water quality testing, community groups are concerned about the River's current state of ecological health and its safety for recreational use. A first step to understanding the River's current state is to …

Characterization of the basal hydraulic system of a surge-type glacier : Trapridge Glacier, 1989-92
… We describe an investigation of the water drainage system beneath Trapridge Glacier, a surge-type glacier in Yukon Territory, Canada. We take two different approaches to characterizing the basal hydraulic system of the glacier. The first approach is borehole response testing, which involves …

A comprehensive environmental and economic sustainability assessment of roadway drainage systems
The primary goal of roadway drainage systems is to quickly remove water from the roadway area to keep driving lanes safe; therefore, these systems are designed to quickly convey water that enters as runoff. However, this runoff carries pollutants (largely originating from vehicles) that travel …
