In the present study, flood hazard of Bangshi River, located in Savar Industrial Area Dhaka District, has been evaluated. The historical extent analysed from Landsat satellite images suggests that most parts study area were flooded during major events Bangladesh. flow data fitted with different analytical frequency distribution functions, and it is found Pearson III function best fits observed ...

Krueng Jambo Balee River, which is a tributary in Aye river basin, flows through the Pertagas pipeline installation (RoW, right of way), at segment Sta. 8+500 to 8+600. Flooding that occurred RoW was caused by draining capacity existing culverts were unsufficient flow discharge from upstream river, thus inundating surrounding area, and overtopping on RoW. This condition serious problem for secu...

Freshwater mussels in California's rivers are potentially very useful as indicators of watershed health and recorders of watershed changes. We report the occurrence and habitat of mussel populations within a continuous 8-km section of the South Fork Eel River in the Northern Coast Range of California. The primary goals of our study were 1) to compile information on species composition and popul...

A dam break is a low-probability, high risk catastrophe event that extremely destructive and has substantial negative socio-economic impact on downstream nearby areas. Simulating breach analyzing flood propagation from those events vital for identifying minimizing the risks associated of location. This study intended to anlayse effect overtopping failure two scenario (a) base-case (scenario wit...

evaluation of surface water quality is a complex process undertakingmultiple parameters. converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.the main aim of this study is to plan effective water resources management system forkarun river by combination of ccmewqi and geographic information system ...

This paper describes the Simulation Program for River Networks (SPRINT) that is proposed as a tool for studying Continental River Dynamics (CRD), the solution of physics-based equations for large-scale river networks. Existing coupled hydrologic/hydraulic models have been unable to solve the full Saint-Venant equations for river networks larger than O(10) elements, but continental scales requir...

Oncogenic ras alleles are among the most common mutations found in patients with acute myeloid leukemia (AML). Previously, the role of oncogenic ras in cancer was assessed in model systems overexpressing oncogenic ras from heterologous promoters. However, there is increasing evidence that subtle differences in gene dosage and regulation of gene expression from endogenous promoters play critical...

A novel whole cell biosensor was constructed for the detection of anionic surfactants in aquatic environments. The analysis was rapid, convenient and did not require organic reagents. In this report, the application of this sensor to river water samples was investigated when applied to environmental samples; other organic substances present in river water may affect the measurement of linear al...

The mixed land covers encompassing bridges (MLB) are integral indicator of the socio-economic hydrological system, and their progressions vital for flood risk assessment. However, most previous studies have neglected a thorough evaluation MLBs (e.g., types, areas, depths) on impacting vulnerability. This paper addresses this research gap by methodically assessing spatial characteristics in floo...

This paper firstly described the dam break in the aspects of theories and models. Break parameters prediction, the understanding of dam break mechanics, peak outflow prediction were shown as the essential for the dam break analysis, and eventually determined the loss of the damages. Secondly, as an application example, Foster Joseph Sayers Dam break was further modeled and analyzed using USACE ...
