Recently the area of application of the mathematical methods is greatly expanded. It is difficult to find an area where it is not used in solving different problems. As is known, is appeared the necessity to solve the differential, integral and integro-differential equations in solving of scientific problems. Note that one of the basic questions in the modern computational mathematics consists of construction of the numerical methods with the high accuracy. Therefore, here, is proposed the multi-step method with higher accuracy than the known. And is constructed the stable methods with the expanded area of stability for solving the above mentioned equations.","PeriodicalId":178151,"journal":{"name":"British Journal of Applied Science & Technology","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114684370","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}

A thorough geophysical / hydrogeological investigation carried out in the area revealed the existence of 7 layers and in the vicinity of the site an unsaturated semi-permeable zone with clay lenses. Site specific hydraulic conductivity of 9m/d was determined through grain size analysis. The groundwater flow direction of the area is from south-east to north-west and the flow system consists of two aquifers separated by a 6.1m thick confining layer. The simulation was carried out for short and long term assessment which gave rise to two sample problems.
