Cold-regions Hydrological Indicators of Change (CHIC) for ecological flow needs assessment

Abstract

Ecological flow needs (EFN) frameworks incorporate a range of ecologically-relevant hydrological variables based on prior knowledge of river regime characteristics. However, when applied in cold regions, these approaches have largely ignored the influence of winter ice cover and the spring freshet on hydrological regimes: key components of river systems in cold regions with important direct effects on water quality, aquatic habitat and ecology. Here, we combine a review of the published literature on cold-regions hydrology and hydro-ecology with available hydrometric information for sites across Canada, a major cold-region country, to explore phenomena unique to these systems. We identify several ecologically-relevant hydrological measures (i.e. annual ice on/off dates, ice-cover duration, spring freshet initiation, peak water level during river ice break-up), pairing these with established metrics for incorporation into an enhanced suite of indicators specifically designed for cold regions. This paper presents the Cold-regions Hydrological Indicators of Change (CHIC), which can provide the basis for the assessment of EFN and climate change assessments in cold-region river ecosystems.

Environmental Change and Human Health in the Brazilian Amazon

The Amazon is a vast region of about 7 million km², encompassing nine countries in the northern part of South America. Around 70% of the Amazon, or approximately 5 million km², are within the Brazilian National boundary (Figure 1). It is, in many aspects, a unique region characterised by the largest stock of biological diversity in the world, an extensive network of rivers, the persistence of traditional Indian population — some still isolated from contacts with modern society — and significant mineral reserves.Around 65% of the Brazilian Amazon region is covered by the different sub-types of the tropical rainforest, with some 100.00 km² of it periodically flooded every year. Another 1.3 million km² are covered with other types of vegetation, especially tropical savannahs. The Brazilian Amazon is home to about 20 million inhabitants of which only 0.8% are Indian; the urbanisation rate in the region is about 60%.Although industrial exploitation of the natural resources of the region has been under way since the last quarter of the 19^th century, it was only in the last 30 years that human intervention in the Amazonian ecosystems has been followed by major negative impacts. This has happened for economic, social and geopolitical reasons and included the opening of new roads, the fiscal incentives for industrialisation in urban areas, building of dams for the generation of hydroelectricity, intensive mining schemes, settlements for agricultural development and cattle raching. This has brought profound social, cultural as well as environmental changes, often resulting in benefits for only a small part of the population. Among the adverse environmental impacts, deforestation stands as the most important one due to its large extension, rapid progress and global and multi-factorial consequences. All these processes — social as well as environmental — have been changing the disease profile in the region (Figure 2). With the intense and widespread exploitation of the Amazon, new diseases are emerging, others are being introduced and the old ones are becoming out of control.

Change detection using CUSUM and modified CUSUM method in air pollutant concentrations at traffic site in Delhi

Understanding the changes in the air pollution of an area due to implementation of control strategies is important as it helps in making further action plans. Time series analysis provides ways to interpret the effect of any policy changes. In this study, the applicability of the CUSUM method for change detection in air pollutant concentrations in Delhi is investigated. The method detects any shift from mean of the process. Delhi has undergone major policy changes during the past few years. Change of fuel in vehicles to compressed natural gas (CNG) is one amongst them. The data observed at a traffic site in Delhi for nitrogen dioxide (NO₂), carbon monoxide (CO) and particulate matter (with size less than 10 micron-PM10) concentrations is used to carry out the analysis. Increase in NO₂ concentration and decrease in CO concentration levels is observed using CUSUM method. The choice of base period does not affect much for these two pollutants but for PM10 concentration, however its role is crucial. In order to counter any variability shifts, the CUSUM method is further modified to account for the change in the variance of the time series. Modified CUSUM method indicated similar nature of variability in NO₂ and PM10, whereas CO variability has decreased significantly after CNG implementation.     

Effects of the imf sector structure in the midlatitude troposphere and stratosphere

Summary The data on geopotential heights and temperatures at 7 pressure levels between 1000-10 hPa above Berlin(52.5 °N, 13.4 °E) are analysed for the winters of 1963–1973. No demonstrable effect of the interplanetary magnetic field sector boundary crossing (IMF SBC) is found in the lower and middle stratosphere, but there is a demonstrable effect in the middle troposphere at the 500 hPa level. This effect is less important than the IMF SBC effect in the tropospheric vorticity area index and seems to be of a different type.

Spherical harmonic expansion of the continents and oceans distribution function

Summary An algorithm is derived to compute the coefficients of a spherical harmonic series for the functionE(, ) representing the distribution of continents and oceans with the least-squares method. Some properties of the system of normal equations, when measuring points are distributed in a regular grid, are discussed. The fully normalized complex coefficients to the ninth degree are given in the table.

Seismic zoning map of Czechoslovakia — version 1987

Summary A new version of the seismic zoning map of Czechoslovakia is presented mainly for use with the revised Building Code SN 730 036 (Seismic Loads on Buildings). In principle, the map contains the expected maximum intensities according to the macroseismic scale MSK-64. The map is based on all historical macroseismic observations in Czechoslovakia, as well as on models of macroseismic fields. The assessment of expected intensities has also been completed by a seismotectonic analysis. It is not feasible to relate the map to a particular time interval, i.e. to estimate the probability of expected maximum intensities, because of the unknown recurrence of extreme events on the territory of Czechoslovakia.

在博斯腾湖水文和水化学实测资料的基础上,研究了博斯腾湖水盐的年际和年内变化。近40年来,水质年际变化经历了好→中→差→中的过程;年内变化与区内最大补给源开都河不同季节河流来水量变化以及湖周农田排盐水等因素直接相关,而湖水的矿化度与水位变化呈负相关。对湖水主要离子含量变化特点和湖区矿化度变化规律的研究表明,湖水补给源及湖水循环状况是影响湖水水质变化的主要因素。     

Health Risk Assessment for Arsenic in Water Sources of Cankiri Province of Turkey

To investigate the levels of arsenic (As) in the water sources of Cankiri Province, the samples were collected from the stations of central Cankiri (n = 27) and Kursunlu town (n = 12) during 2009 and 2010. The concentrations of As were analyzed with an atomic absorption spectrophotometer, and then compared with permissible limit, 10 µg/L in drinking water, by Turkish legislation and World Health Organization (WHO). The As levels were higher than this limit (mean value 10–30 µg/L in 26 stations), whereas, they were found to be >30 µg/L in 12 sampling points. The water sources were categorized for health risk assessment such as reservoir, tap, well, and spring, and then chronic daily intake for oral and dermal exposure to As via drinking water, hazard quotient (HQ), and hazard index were calculated by using indices. The HQ values were found to be >1 in all samples of Cankiri Province. The effects of As on human health were then evaluated using carcinogenic risk (CR). CR values for As were also estimated to be >10^?5 in drinking water samples of Cankiri Province and might exert potential CR for people. These assessments would point out required drinking water treatment strategy to ensure safety of consumers.     

Consequences of transducer inductance for seismograph calibration

Summary The magnification achieved with the standard sine-wave method using seismometers with the calibration and signal coils tightly wound on the same coil former can be erroneous at high frequencies due to the mutual inductance between both coils. An attempt was made to eliminate this influence from the calibration data. The application of theoretical equations was tested with a short-period digital seismograph.
