Measuring suspended sediment in fluvial systems is critical to understanding and managing water resources. Sampling has been the primary means of sediment. Specialized samplers, sampling methods, laboratory methods developed by select U.S. Federal Agencies are more representative river stream conditions than commonly used grab total solids (TSS) but not widely because they expensive, time consu...

Suspended solids removal performance of a manufactured stormwater treatment device varies greatly with operating conditions and laboratory or field evaluation techniques. Laboratory testing and field monitoring protocols have been established to evaluate the performance (removal efficiency or effluent concentration) of manufactured stormwater treatment devices and other structural BMPs. However...

Both anthropogenic and natural sources of pollution are regionally significant. Therefore, in order to monitor protect the quality Langat River from deterioration, we use Artificial Intelligence (AI) model river water quality. This study has applied several machine learning models (two support vector machines (SVMs), six regression models, artificial neural network (ANN)) predict total suspende...

This paper presents results of a 3 year pilot study of surface erosion on forest roads in the Jackson Demonstration State Forest in California’s coastal redwood region. Ten road segments representing a range of surface, grade, and ditch conditions were selected for the study. At each segment, settling basins with tipping buckets were installed to measure coarse sediment and total runoff. Labora...

Following increasing interest in the use of UltraFiltration (UF) membrane processes as an alternative advanced disinfection technique, the performance of a UF pilot plant was investigated under two opposite operating conditions (“stressed operating condition” versus “conventional operating condition”). The results indicate that for both conditions, the reclaimed effluent complied with the Itali...

In the wastewater treatment process, floatation unit have been developed to remove particles or flocs that tend be difficult settle, such as fat oil and grease (FOG) total suspended solids (TSS). Flotation is a operation can separate liquid phase solid from phase, this occur due presence of saturated air which mixed so it contains fine bubbles help separated. This research was conducted by trea...

In this study, landfill leachate treatment by coagulation and optimization of process parameters were aimed. Alum (Al2(SO4)3) Poly Aluminum Chloride (PACl) used as coagulants to remove total suspended solids (TSS) from leachate, coagulant dose, reaction time, pH optimized variables. The Box-Behnken, one the response surface methodology designs, was in modeling process. R2 values very high (&amp...

This study investigated the potential effect of climate changes on stormwater pollution runoff characteristics and the treatment efficiency of a stormwater retention pond in a 95 ha catchment in Denmark. An integrated dynamic stormwater runoff quality and treatment model was used to simulate two scenarios: one representing the current climate and another representing a future climate scenario w...

The monitoring of water colour parameters can provide an important diagnostic tool for the assessment of aquatic ecosystem condition. Remote sensing has long been used to effectively monitor chlorophyll concentrations in open ocean systems; however, operational monitoring in coastal and estuarine areas has been limited because of the inherent complexities of coastal systems, and the coarse spec...
