چکیده
Abstnn-The purpose of t h ~ s review paper is to presenl the technical basis for es(abiishing srdiment quality sntaia using equilibrium partitioning (EqPJ. Equilibrium panitioning IS chosen because it addresses th? two principal technical issues that must be resolred: the varying bioavailability of chemicals in sediments and the choice of rhc appropriate b~ological effects conetooation. The data that are used to examine the ~uuestion of varying bioavailabili across sediments are from toxicity and bioaccumulation experiments utilizing the same chemical and test organism but different sediments. It has been found that if the different sediments in each ex~eriment are compared. there is essentiallv no relationshio betweensedimmt chemical concentrations on a dm weight basis and bioio~ical effkcts. However. if the chemical concentrations in the oore water ofihe &d~ ~ . . ~ ~~~~~~~~ ~ ~~~~~~~~~

Sediment Quality Criteria: Numeric Chemical– vs. Biological Effects–Based Approaches
The US EPA and state regulatory agencies are developing sediment quality criteria and standards for the protection of water quality from sediment-associated contaminants. Many of the approaches being pursued rely in whole or substantive part on the bulk concentrations of selected chemical contaminants in the sediment as a basis for determining those sediments sufficiently contaminated to warran...

Being available the accurate data on carried sediment has accounted as an important factor for making decision about constructing of river structures and determining of dam life. To accomplish this object, a number methods have been proposed so that sediment rate curving as a hydrological method has been developed for doing it. Ignoring differences between season's values causes to lower the pr...
متن کاملInvestigating the geological potential of the Birjand area for establishing and extending flood farms (Bandsar)
Khorasan Province is one of the areas in which it is not possible to cultivate farmlands because of low rainfall, and hence, flood farms (bandsar in local dialect) are considered an effective traditional method for flood cultivation in the region. We used a geological map of Birjand at a scale of 1: 250,000 to select the study area. This area includes the city of Birjand and numerous population...
متن کاملApplying Artificial Neural Network Algorithms to Estimate Suspended Sediment Load (Case Study: Kasilian Catchment, Iran)
Estimate of sediment load is required in a wide spectrum of water resources engineering problems. The nonlinear nature of suspended sediment load series necessitates the utilization of nonlinear methods to simulate the suspended sediment load. In this study Artificial Neural Networks (ANNs) are employed to estimate daily suspended sediment load. Two different ANN algorithms, Multi Layer Perce...
