The research investigates the transport and fate of heavy metal entrenchment into the River Nent from abandoned spoil waste at the former mine site. The River Nent is found to maintain a circum-neutral pH and contains high concentrations of dissolved zinc (Zn) and lead (Pb) of 0.70mg/l and 0.08mg/l respectively at flow rate of 34.5l/s. Relative concentration of sulphate and carbonate ions is observed to influence the river pH. This condition has a marked effect on the concentrations of Zn and an insignificant effect on Pb, copper (Cu), cadmium (Cd) and nickel (Ni). A leaching experiment shows

Based on research findings, Bangladesh’s river water, crucial for domestic, agricultural, and industrial use, has long been in a terrible situation. There have been numerous instances of significant contamination in the waterways surrounding Dhaka city, including the Buriganga River, and in Chattogram city, including the Karnaphuli River, over the past 40 years. The existing data demonstrate that other urban rivers, particularly Karatoa, Teesta, Rupsa, Pasur, and Padma, are also in severe condition due to the disposition of huge pollutants.

The River Chief System is an administrative model of water environment governance currently adopted in China.

Flood frequency analysis is crucial for understanding flood risks in specific regions. This study applied the Gumbel Distribution Method to analyze flood frequency using river discharge data from the Kadamaian and Wariu Rivers in Kota Belud, Sabah, Malaysia. The analysis involved data collection, parameter estimation, goodness-of-fit testing, and determination of annual recurrence intervals (ARIs). The study found that the ARIs for the Kadamaian and Wariu Rivers are 50 years and 30 years, respectively, highlighting the need for targeted flood mitigation strategies in these areas. These finding

Physical disturbance in the form of storm events has been implicated as a major determinant of community structure in streams. But there has been limited study of this effect on individual taxa within the communities. Such work is needed because of untested assumptions regarding the behavior of bioindicator species in these systems. Development of intricate indices of insect tolerances to organic pollution have become commonplace in environmental monitoring. However, research on the effects of natural disturbance on biological water quality assessment is lacking. Hydropsychid caddisflies are r

Prairie rivers of the Great Plains, USA, provide important habitat for the federally threatened piping plover (“plover”, Charadrius melodus). Plovers nest on open to sparsely vegetated river sandbars, and their demographic rates are closely linked to habitat availability and quality, as well as river flow. The Niobrara River in northern Nebraska has supported 22–41% of the state’s plovers since species listing in 1986, but the population and habitat are relatively understudied, and both have declined since 2010.

This thesis is concerned with developing an archaeological theory of movement. Movement forms one of the most important phenomena of human life. It is an essential component of being, action and identity indeed without it we cease to live. Notwithstanding, human pedestrian movement remains little theorised within prehistoric contexts and when it is considered is usually restricted to seasonal mobilities or patterns of movement around and within the architectures of Neolithic monuments. This thesis goes beyond this narrow focus by examining movement as an integral facet of quotidian life. Notab

This fish species is among the most abundant of fishes in many river systems of the region and is considered an important predator in these habitats, feeding on invertebrates and small fish (Whitfield, 1998; Strydom & Neira, 2006; Wasserman, 2012; Wasserman et al., 2014).

Clearing of old growth forests resulted in a substantial loss of nesting habitat for cavity-nesting waterfowl during the late 19th and early 20th centuries. Since then, many hardwood forests have matured into size classes capable of producing cavities suitable for nesting ducks. To quantify changes in cavity availability in U. S. Fish and Wildlife Service Region 3, which contains most of the midwestern U.S., I examined current cavity availability at 4 sites where cavity availability had been estimated in the past; Mingo National Wildlife Refuge (NWR) in Missouri, Shiawassee NWR in Michigan,

Recently published laboratory S-N testing of Grade 29 titanium Gas Tungsten Arc-welded riser pipe specimens in air vs

Abstract Storage of aluminun-clad spent nuclear fuel at the Savannah River Site (SRS) and other locations in the U. S. and around the world has been a concern over the past decade because of the long time interim storage requirements in water. Pitting corrosion of production aluminum-clad fuel in the early 1990’s at SRS was attributed to less than optimum quality water and corrective action taken has resulted in no new pitting since 1994. The knowledge gained from the corrosion surveillance testing and other investigations at SRS over the past 8 years has provided an insight into factors affec

Abstract Corrosive conditions can develop where pipeline sediments accumulate in crude transmission pipelines. The accumulation of sediment at pipeline over bends occurs when inertial forces in the pipe flow cause a thickening in the boundary layer at the pipe floor, which decreases the shear stresses responsible of mobilizing solids. The Shields method has been proposed to predict the accumulation of solid particles taking into account the critical role that shear stress plays in transportation of solids. The Shields method was originally developed as a river model, a simple dimensionless dia

In 1995, Japan suffered devastating damage from the Great Hanshin-Awaji Earthquake and has since been devoted to disaster management. Since there has been no report anywhere in the world on a sea-based relief system, our research will lead to a review of ocean spaces in terms of their value in waterfront metropolitan cities.

The Clackamas River in Oregon is a drinking water source for upwards of 300,000 people living in the Portland metro region. This river experiences seasonal low flow during the annual dry season throughout summer and early fall when endangered salmon species return to the river to spawn. This dry season also coincides with the highest period of urban water use. Since precipitation is minimal at this time, water users choose to water their lawns to make up for the lack of rain which contributes to water use tripling during the driest part of the year. To promote local water conservation, the Cla

The NERI banding station has banded over 4,500 individuals over 10,700 net hours in the twenty-three years it has been in operation and has captured 80 different species. Total captures, capture rate, and total species have been declining annually over the study period. Species associated with early-successional/shrubland habitat also declined over the study period, which is consistent with regional trends dur

The research was conducted in a circulating fluidized bed having diameter and height of riser of 5 and 200 cm., respectively, at ambient temperature and pressure. The objective was to study hydrodynamics of mixed-feed between sand and various biomasses including rice husk, sawdust, and bagasse at 50% by volume. The air flow rate was in the range of 4.2-5.7 m/s. The velocity of sand in the riser was obtained by using a high speed camera and an image processing software. The results showed that at the lowest gas velocity the velocities of sand in the mixture were higher than those in the single

This research was conducted to create an automated, efficient process to classify patterns and orientations of swales within the Lower Mississippi Valley (LMV) to support levee risk assessments. Two machine learning algorithms are used to train the classification models: a convolutional neural network and a U-net. The resulting workflow can identify linear topographic features but is unable to reliably differentiate swales from o
