water turbidity

During the December to April period when the water turbidity is low, fishing may be done from the shore.

Water turbidity is moderate with a Secchi disc reading of 14 centimetres.

This measure is known as the Secchi depth and is related to water turbidity.

Water supply to most regions was cut due to damage to pipelines and high water turbidity.

Biologists would analyze subsequent impacts to aquatic flora and fauna from increases in water turbidity.

All differences should be recorded (e.g. soil type, water turbidity, crop species, etc.).

Based on previously read material, I hypothesize that both water turbidity and species introduction have the greatest effect on declining populations.

With such high plasticity of environmental stress, it can withstand certain levels of pollution, heavy metal density, and water turbidity.

Algal blooms increase water turbidity, suffocating aquatic plants, and can deplete oxygen, killing fish.

"And water turbidity.

Water pre-filtration is critical so as to lower water turbidity which will lower UVC penetration.

From a satellite, a proxy measurement of the water turbidity can be made by examining the amount of reflectance in the visible region of the electromagnetic spectrum.

Tuna fishing tends to be optimum when water turbidity, measured by the maximum depth a secchi disc can be seen during a sunny day, is 15 to 35 metres.

The feeding behaviour of the carp undermined the reedbeds and increased water turbidity, leading to the death of submerged plants, decreased oxygen levels and the decline of small aquatic wildlife.

The specific habitat occupied by the species is vulnerable to beachfront habitat alteration activities including beach renourishment projects and dredge-and-fill operations, both of which increase sedimentation and water turbidity and cover necessary habitat.

Increased pollution and siltation can result in higher water turbidity, making it difficult for this darter, and many other fish species, to forage for food, breed, and potentially decreasing the ability to avoid predators.

The euphotic zone is somewhat arbitrarily defined as extending from the surface to the depth where the light intensity is approximately 0.1-1% of surface sunlight irradiance, depending on season, latitude and degree of water turbidity.

In contrast to its neighbour Musters (separated by a 12 km wide 695 m high isthmus) Colhué has an average 2 meters depth and high water turbidity due to suspended sediments deposited by constant wind.

Recent studies suggest a combined effort to closely monitor physical aspects of E. camurum habitats, such as water turbidity and flow rate, and water chemistry, such as nitrates and phosphorus concentrations, which occur from agriculture runoff.

In July 1965, heavy rainfall caused the Hida River water level to rise, and water discharged from Asahi Dam caused long-term water turbidity along the Hida River, heavily affecting the fishing industry.

The direct filtration treatment process is marginal when raw water turbidity is high, which results in the need to do frequent filter backwashes dropping the plant efficiency as low as 70%, reducing effective capacity from 15 to 10.5 Million Gallons per Day.

Rapid population growth and a more stringent regulatory environment have resulted in water demands that are already at the current WTP capacity during peak use, which is apparent in the early summer when high water turbidity periods overlap with high consumer demand.

Water turbidity (i.e., the amount of suspended & colloidal solids contained in the water to be treated) must be low, such that the water is clear, for UV purification to work well - thus a pre-filter step might be necessary.

Unfortunately though new tourism industry has caused environmental problems; Barge hulls and propellers may cause "physical damage and uprooting" of plants and turbulence may increase water turbidity to the extent that light may not reach underwater plants, reducing photosynthesis (Murphy et al. 1983).
