Materials and methods Assessment of effectiveness of wastewater disposal in a treatment plant was carried out using elements of reliability theory. Research covered a period from March 2014 to December 2015. The content of pollution indicators in treated wastewater was compared with limit values included in the Regulation of the Minister of the Environment of November 18, 2014. Reliability analysis was performed for the following pollution indicators: BOD5, CODCr and total suspended solids. Reliability coefficient RF was assumed as a basis for reliability calculations. Next, technological treatment efficiency index (Pso) was calculated. Results and conclusions An analysis of treated wastewater in relation to three tested parameters proved that the treatment plant works properly. Limit values of examined indicators – included in the Regulation (Dz. U. 2014 poz. 1800) – have not been exceeded. Also, all the analysed parameters have shown high percentage of pollutant reduction, ranging between 96% for CODCr and 99% for BOD5. Obtained values of reliability indicators for the analysed treatment plant confirm its good condition.","PeriodicalId":51904,"journal":{"name":"Acta Scientiarum Polonorum-Formatio Circumiectus","volume":"44 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84636133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods To assess the flood routing and surge reduction, a mathematical model of the river catchment was implemented. This was a lumped hydrological model, based on the SCS-CN method. Channel routing was performed, using kinematic wave equation. The sub-catchments have been determined based on the topographic maps and rain sewage systems. In the paper, the hydrological model of the water system of Potok Oruński (Oruński Stream) is presented with particular focus on the new and renovated retention structures. Hydrological modelling system of HEC HMS was used to simulate the catchment’s response to precipitation. Thanks to the recently established monitoring system of the Oruński Stream, it was possible to calibrate and validate the model. Single rain episode from April 2018 was used to perform model calibration, proving its high compatibility. The calibrated model was then used to reproduce the flood surge of July 2001, using historical catchment data. The peak discharge demonstrated a need for additional retention in the studied catchment. Theoretical scenarios were also modelled. The precipitation volume was calculated based on the IFS. As a worst-case scenario, the rain producing the most intense surface runoff was included. In all simulations, historical conditions as well the current state (2018) and projected further urbanisation of the catchment were taken into consideration. Results and conclusions Results of the study have shown reduction of the historical flood surge from July 2001 by nearly 60% when all existing flood protection systems were used.","PeriodicalId":51904,"journal":{"name":"Acta Scientiarum Polonorum-Formatio Circumiectus","volume":"73 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74138124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An analysis of predictability of ice phenomena in relation to stability and seasonality and an understanding mutual interactions between parameters describing ice regime of the lake. Material and methods Data from the Jagodne Małe water gauge station on Jagodne Lake, concerning: the dates of the beginning and the end of ice phenomena, the beginning and the end of ice cover, and the thickness of ice cover from 1975–2015. Average monthly air temperature from the IMGW-PIB synoptic station in Mikołajki. Statistical analysis based on trend analysis using the non-parametric Mann-Kendall test and the Colwell method. Results and conclusions The research has proven that Jagodne Lake shows some tendencies to change in ice regime over the last four decades. These trends should be identified with a successive shortening of ice season and a decrease of the thickness of ice cover. However, these changes in the case of the beginning and the end of ice phenomena (including ice cover) and the thickness of ice cover are not statistically significant. Only shortening of ice phenomena duration was observed and confirmed by the Mann-Kendall statistical test. The analyzed object reacts similarly to most of lakes, for which research on changes in icing was conducted. The observed increase of average temperatures in April had an influence on shortening of ice phenomena.","PeriodicalId":51904,"journal":{"name":"Acta Scientiarum Polonorum-Formatio Circumiectus","volume":"3 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88928316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article presents a method of functioning of a multidimensional cadastre, with data applicable to various fields, e.g. security. The research method includes both an analysis of literature on land and building records as well as a use of GIS tools in network analysis. The research focused on a use of data regarding building interior in regard to public safety. It was realised using available GIS tools. Conclusions and results The method of using graphical data related to premises (interior of buildings) presented in this paper extends beyond the currently performed cadastral functions and can be used, for example, to find an escape route. The task was realised with available GIS tools. In Poland, there is a legal obligation to register dates related to real estate, which gives the opportunity to create a 3D + cadastre. So far, there are no legal regulations pertaining to registration of geometrical data of premises and their presentation in a graphical part of a record. Full geometric and descriptive data on plots, buildings and premises can be used as an effective tool in space management: spatial planning, environmental protection, protection of natural resources, development of urbanization, as well as public safety","PeriodicalId":51904,"journal":{"name":"Acta Scientiarum Polonorum-Formatio Circumiectus","volume":"17 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78453933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shear strength parameters of soils embedded in the dam’s body were also determined, i.e. undrained shear strength basing on field tests and the angle of internal friction and cohesion in a direct shear apparatus. Materials and methods Field tests included the determination of bulk density of soil and sounding with a dynamic probing light together with identifying the undrained shear strength in four sections located on the downstream slope over a section of about 300 m. Grain composition and compaction parameters were measured in laboratory tests in the Proctor apparatus. Shear strength parameters were also determined, i.e. the angle of internal friction and cohesion in a direct shear apparatus on samples without and with saturation during consolidation and shearing. Results and conclusions The analysis of obtained results indicates that the values of degree of compaction and compaction index – estimated on the basis of their correlations – differed significantly depending on the probe vane. It was found that for the most part the soils making the side dam’s body were characterized by low values of compaction index. However, the stability of the entire object was assessed as high due to high values of shear strength parameters from the vane probe test and the direct shear apparatus. Analysis of the results of shear strength tests in field and laboratory conditions showed no clear correlations between the tested parameters.","PeriodicalId":51904,"journal":{"name":"Acta Scientiarum Polonorum-Formatio Circumiectus","volume":"32 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85791537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
