Abstract

This study aims to analyze the Diyala weir problems and compares it with thesafe limit and proposes the treatment for these problems. One of the most influencingproblems in the site of weir was the formation of the hydraulic jump, it was foundthat the scour occurs due to the position of the hydraulic jump and the sequence depthof the jump is higher than the tail water depth. Some treatment procedures aresuggested, these treatments cover this problem by presenting a suitable stilling basinas well as recommended to use a low weir at end of basin to produce a back watercurve that should be increase the stage of tail water and ensuring the stability of ahydraulic jump .

Abstract

This study provides practical results in the use of the composite from sulfate resistance Portland cement (PC) and Quicklime (LQ) to improve and stabilize of soils in Al - Zaafaraniya site in Baghdad governorate and the Garma Ali site in Al Basra governorate, Iraq. PC and LQ were added in percentages of 2,4,6,8 and 10% and 2 and 4%, by dry weight, respectively. Laboratory tests to determine Atterberg,s limits, standard proctor test, USC test and UUU test (unconsolidation, undrained and unsaturated) were conducted. The results achieved a significant improvement in workability, unconfined compressive strength and shear strength. The results of the unconfinedicompressiveistrength test and UUU test for natural and improved soil reveal that the shear strength increase as lime and cement content increase and with increasing curing (0, 7 and 28)days.

Abstract

Surface interpolation techniques are usually used to createcontinuous data (i.e. raster data) from distributed set of point data over ageographical region. There are deterministic and stochastic (geostatistical)interpolation techniques can be used to create spatial raster surface. In thispaper, the comparison between the Inverse Distance Weight (IDW)interpolation method as deterministic method and the Kriging interpolationmethod as stochastic method is done to determine the best performance formeasuring levels of ground water in Baghdad Governorate. Spatial rastersurface surfaces as ground water prediction maps are generated from eachmethod by using average ground water level measured at 206 wells in thestudy area. These maps are shown spatial variation in the ground waterlevels and they have complete different. The IDW method results a refinedmap and lesser error than the Kriging method. Thus, the analysis shows thatthe IDW gives better real performance of measuring levels of ground waterin Baghdad Governorate.
