Observation Results

In Indonesia it was identified that there were much of polluted stream flow which cause improper consumed water. One of the rivers which has low of water qualities is Citarum River, West Java. However, along the Citarum river, there were built three reservoir dams (Saguling, Cirata and Jatiluhur) that can control the condition of river water regime. Research was conducted in Citarum watershed to determine the role of those reservoirs on water quality control. Seven stations along the river were selected as observation posts of water samples. Based on the observation results it was indicated that water pollutants within Citarum river was very high. However, those pollutants could be purified or reduced by those reservoirs, hence water discharge from the reservoirs has better quality. In the future, deposition of those pollutants within the dam may has negative environment impact. Therefore, to sustain that function of the dam, comprehensive efforts on reducing pollutants from the catchment area is urgently required.

A Site

Water Quality control for construction sites is a requirement at any site within the United States. Erosion Controls are the first, and many times, last preventative measure for water discharge from a site. If these fail, streams, wetlands, or even off-site upland areas (yards, etc.) are adversely affected. Site quality is affected when valuable soil is lost and restoration requires replacement. Human exposure to contaminants, violation of governmental regulations, contractor reputation, and the overall economics involved in construction are at risk.

Soil And Water

Pesticides used on agricultural lands are among the significant diffuse sources of pollutants. They are poisons and can be particularly dangerous when misused and/or applied without care. Although certain characteristics of pesticides are well known, their final characteristics after they reach a waterbody are extremely difficult to estimate. Regarding the soil and water environment, it is necessary to conduct both a field study and laboratory analysis. Such a study has been performed in the catchment area of Dalyan Lagoon, Turkey, joining the Mediterranean Sea, that was selected as the pilot region. The input of pesticides, transport in soil and transfer to the water environment together with their probable impacts on water quality are determined by conducting detailed field surveys and water residue analyses. Within the scope of the study, the behavior and fate of pesticides both in soil and water are investigated in detail. Water residue experiments are conducted on four sets of water samples representing the seasons of the year 1999-2000 for the pre-selected 6 pesticides. Two sets of water samples (surface and bottom) are taken from the 16 stations along the lagoon channel and two lakes within the catchment area. The results and findings show the significance of the use of pesticides as they exist in the water environment around and/or slightly above the limits stated in the national current regulations except dichlorvos which presents very high values compared to its tolerance limit. Of particular interest, the results are used to enlighten the farmers and the public and increase awareness of pesticides as contaminants in valuable coastal waters.

Abstract The data set of the Warta discharges in Poznań (Poland) is one of the largest in the world as the daily observations of river stages have been conducted without interruptions since January, 1st, 1822. The Poznań measurement profile is situated in the 243.6 km and closes the catchment area of approximately 25 thousand square kilometers. The data used as the input in the paper were daily values of the Warta discharges in Poznań in the years 1822-2012. The climate in Poznań, a city situated in the centre of the Wielkopolska (Greater Poland) region, is relatively stable (Miler et al. 2005). Also the Warta River runoff shows considerable stability, especially in terms of mean annual values. Short-term trends are random in character. It was found that the Jeziorsko reservoir (total storage volume of 203 000 000 m3, officially put to use on September, 9th, 1987) significantly reduced daily variability of the flows and reduced peak discharge of the flood wave in the summer of 1997 on the Warta River at Poznań. The calculated periodogram for mean annual discharges of the Warta River in Poznań shows that there are main periodicities of ca. 10 year lengths. The research of the Provincial Inspectorate for Environmental Protection (WIOŚ) in Poznań shows a gradual improvement of water quality in the Warta River in Poznań.

In rivers with diffuse pollution intensification of self-purification is the main method of water quality control. The Moscow River is subjected to an extreme anthropogenic load. Hydro/chemical and hydro/biological monitoring at the reach from the entering the city to the estuary has revealed the factors that influence self-purification. The paper demonstrates regulation of the self-purification processes through adjustment of the river ecosystem in the zone of biologically treated waters discharge.

Evaluation of the hydrological role of wetlands in the Włodawka River catchment (Polesie Lubelskie) The Włodawka River catchment of an area of 725 km2 covers the central and eastern part of the Łęczna-Włodawa Lake District. Evaluation of the role of hydrogenic areas in runoff creation was based on materials of the Department of Hydrography and the Institute of Meteorology and Water Management data. The analysis was conducted for selected catchments in which additional hydrometric measurements and water quality tests were done. Such parameters as: the share of hydrogenic surfaces in total catchment area, types of wetlands, their hypsometric location and position with reference to drainage streams were taken into consideration for evaluation. The degree of anthropogenic transformation of the marshland was expressed in terms of density and depth of the drainage ditches that dissect it. It was found that the drained gyttja of Krowie Bagno plays a considerable role in increasing the minimum discharge. Wetlands in the Włodawka River catchment influence the conditions of the runoff and water quality, which is noticeable, primarily, in the concentration of organic carbon, and of nitrogen and phosphorus compounds.

Currently existed special features of the water regime, namely the role of flood runoff in its formation in the rivers of European Russia has been considered. Changes of characteristic data and maximal water discharge rates for thaw and rain floods, as well as runoff volumes for each phase of the hydrological year has been demonstrated on the basis of the hydrograph split by the genetic components. It has been shown that the winter period meteorological characteristics changes reflects on the formation of low water a flood water contents during thaws. This, in turn, affected the whole within-year distribution of the runoff, thus causing the noticeable transformation of typical hydrograph of the most of the rivers of European Russia.

THE PROPERTY to be discussed is a mixed sheep and cropping unit, situated ei ht a miles east of Ashburton and midway between the Ra aia and the Ashburton rivers. Average annual rainfall is 27 in., evenly spread, but there is very high summer evaporation and therefore frequent droughts. On average, the soil is below wilting point for 40 to 50 days each summer. Winters are cold with the soil temperature being below 48°F for about four months each year. The soil is a Lismore stony silt loam averaging 9 in. in depth over gravel.

Vasavaleha is one of the best medicine given for respiratory diseases. Corona viruses typically affect the respiratory system, causing symptoms such as coughing, fever and shortness of breath. It also affects host immune system of human body. Spreading rate of this disease is very high. Whole world is seeking for the treatment which can uproots this diseases. There in no vaccine available till date against this pandemic disease. Ayurveda mainly focuses on prevention of diseases alongwith its total cure. Rajyakshma Vyadhi is MadhyamMarga Roga as per Ayurveda. It shows many symptoms such as Kasa, Shwasa etc. By overall view of Covid 19, shows its resemblance with Rajyakshma Vyadhi described in Ayurveda. Vasavaleha is a Kalpa which is described in Rogadhikara of Rajyakshma. It shows Kasahara, Shwashara properties. It consists of Vasa, Pipalli, Madhu and Goghrita. These components shows actions like bronchodilation, antitussive effect and many more other actions. Pipalli shows important Rasayana effect. So in present review, we have tried to focus on role of Vasavaleha in the management of Covid 19. This can be used as preventive as well as adjuvant medication in treating Covid 19. There is need of further clinical research to rule of exact action of Vasavaleha against Covid 19.
