Improved Drawdown Facilities at Three Flood Storage Reservoirs
Author(s) Andrew Pepper, BSc(Hons), CEng, MICE, FCIWEM, C.WEM Abstract The Hertfordshire and North London Area of the Environment Agency has 18 flood storage reservoirs (FSRs) which come within the remit of the Reservoirs Act 1975. Many have fixed flow control...
Flow Dependent Constriction-size Distribution in Gap-graded Soils: a Statistical Inference
Author(s) S. M. Dassanayake*† A. Mousa Abstract The clogging–unclogging process in gap-graded soils is a result of the migration of seepage-driven fines, which subsequently induces measurable changes in the local hydraulic gradients. This process can be...
Water Quality Analysis and Corrosion Potential of the Distribution Network of Patna, Bihar, India
Authors Saurabh Kumar, MTech Reena Singh, PhD Nityanand Singh Maurya, PhD Abstract Drinking water distribution system water quality can be affected by chemical and microbial processes. A change in the chemical concentration of water is a result of pipe scaling...
Compression Waves in Semi-circular Channel
Authors Emelia Dara Soechiarto, BEng Davide Wűthrich, PhD Hubert Chanson, PhD, DEng Abstract Partially filled pipe flows are commonly observed in urban hydraulics, sewers and road crossings.The occurrence of a compression wave in the confined space may result...
Water Surface Profile Prediction in Compound Channels with Vegetated Floodplains
Authors Marzieh Mohseni, PhD Amineh Naseri, MSc Abstract Floods have become one of the most dangerous and frequent natural disasters. Most rivers are characterised by compound cross-sections that are usually contain vegetation. The ability to simulate water...
