Collection of storm water runoff and forcing it into the groundwater is the need of the hour to sustain the ground water table. However, the runoff entraps various types of sediments and other floating objects whose removal are essential to avoid pollution of ground water and blocking of pores of aquifer. However, it requires regular cleaning and maintenance due to problem of clogging. To evalu...

Groundwater is the source of all tap water in Kumamoto City, Japan. However, concentration nitrate nitrogen (NO3−-N) tends to increase every year due influences overfertilization, field disposal livestock manure, and inflow domestic wastewater. A heterotrophic nitrification–aerobic denitrification (HN-AD) system an attractive approach for nitrate-nitrogen removal. In this study, Rhodotorula gra...

Moderation of stream temperatures by riparian shading and groundwater are known to promote growth and survival of salmonid fishes, but effects of riparian shade and groundwater on to be growth of warmwater stream fishes are poorly understood or assumed to be negligible. We used stream temperature models to relate shading from riparian vegetation and groundwater inflow to summer water temperatur...

Position-dependent concentrations of trichloroethylene and methyl-tert-butyl ether are considered for a 2.81-km section of the Aberjona River in Massachusetts, USA. This river flows through Woburn and Winchester (Massachusetts, USA), an area that is highly urbanized, has a long history of industrial activities dating to the early 1800s, and has gained national attention because of contamination...

the paper is concerned with the hydrogeological appraisal of the proposed mining operations in thethar lignite field in sindh, pakistan. the thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. in the thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and m...

Construction of underground research laboratories and geological disposal facilities has a significant transient impact on groundwater flow, leading to a drawdown in the water table and groundwater pressures, and groundwater inflow into shafts, access ways and tunnels accompanied by desaturation of the surrounding rock. Modelling the impact of underground facilities on groundwater flow is impor...

This paper was undertaken to compare eleven utilities where part or all of the utility tested for infiltration and inflow with intention of determining the value data gathered from midnight investigations, comparing potential costs (in 2020 dollars), and understanding whether statistical methods can be used predict potential problems on system. Inflow amounts identified a utility system w...

Riverbank filtration (RBF) consists of green drinking water production in many regions and is used as a pre-treatment phase. This study investigates the performance RBF Nile delta, Egypt, for climate change population growth scenarios 2030, 2040, 2050. presents new method predicting sharing riverbanks considering three cases: i) river stage controlling levels river, ii) increasing pumping, iii)...
