Watershed is not simply the hydrological unit but also socio-political-ecological entity which plays crucial role in determining food, social, and economical security and provides life support services to rural people. The criteria for selecting watershed size also depend on the objectives of the development and terrain slope. A large watershed can be managed in plain valley areas or where forest or pasture development is the main objective. In hilly areas or where intensive agriculture development is planned, the size of watershed relatively preferred is small. This paper describes the concept, principles and challenges in watershed management.
Groundwater quality has a major significance, being the major alternate source of domestic, industrial and drinking water supply and therefore it needs greater attention of all concerned The present study demonstrates the spatial distribution of various chemical parameters, such as pH, F, Cl, iron, nitrate, alkalinity, TDS, total hardness etc. using GIS techniques for Hilauli block of Unnao district, Uttar Pradesh. A Water Quality Index (WQI) was calculated to find the suitability of water for drinking purpose. The overall analysis of the water quality index in the study area revealed that most of the area with > 50 value exhibited poor, very poor and unsuitable water quality.
It is expected that in the near future, the civil engineering community will have to produce structures in harmony with the concept of sustainable development through the use of high-performance materials with low environmental impact that are produced at a reasonable cost. Geopolymer concrete provides one route toward this objective synthesized from the materials of geological origin or by product materials such as fly ash, which are rich in silicon and aluminum. But major disadvantage of geopolymer concrete (GPC) is curing of this concrete is to be carried at elevated temperatures and this concrete is recommended for precast members because of temperature curing. This paper finds solution to overcome these problems in GPC by replacing fly ash with cement and the tests show encouraging results by which this new cement added GPC can be made as Eco-friendly construction material.
Now-a-days ferrocement elements are used as building material as well as structural materials, since ferrocement can put the building into diet. Ferrocement elements are thin, flexible and the steel reinforcement is distributed widely throughout the cement mortar. Instead of cement mortar, self compacting mortar is used in order to eliminate the external vibration and to overcome the difficulties and problems in the construction process and it can flow through congested formwork and corners where the conventional cement mortar cannot facilitate perfect filling and compaction. The objective of this study was to develop the properties of self compacting mortar using SCC principles. 3 mixes of SCM were prepared by maintaining constant percentage of Super Plasticizer and Viscosity Modifying Agent of 0.85% and 0.23% respectively and varying w/c in the range of 0.40, 0.45 and 0.50 with mortar ratio of 1:2. For each mixes 9 cubes (7cm X 7cm X 7cm) were cast. The workability of the fresh mortar determined using slump flow and V-funnel tests. The hardened properties were determined at 3, 7, 28 days of age. The SCM test results were compared with the control specimen to see the inference of self-compatibility. This mortar developed is applied in the construction of the ferrocement slabs and their behaviour was studied.
The application of ground penetrating radar (GPR) for pavement evaluation is relatively new concept in India, especially for transportation infrastructure study to evaluate its defects and condition rapidly, continuously and non-destructively. The images of the studied pavement section containing underground utility (here metallic water pipes & electric cables are taken) items show hyperbolic signatures and by using velocity calibration by hyperbolic matching approach it is possible to determine the depth and leakage status. But, generally the main problem that is encountered in the analysis of the GPR image is the occurrence of false hyperbolic signatures which may appear due to the reflection from nearby big trees, houses and overhead bridges/ under ways. It is therefore, important to resolve the issue of detection of false target in air by GPR. Thus, in the present work practical data have been acquired using 250 MHz ground coupled GPR from the areas having big objects that can interfere with the GPR images. The GPR signatures of the trees, fly over and overhead pathway have been collected, and based on the GPR acquired velocity (from GPR image) of the electromagnetic (EM) wave propagating through the ground has been analyzed to differentiate between the air objects and the ground objects. After analysis it has been found that if the GPR extracted velocity is within the range of (0.050 m/ns to 0.150 m/ns), it represents all sorts of ground materials (generally used for construction) under various moisture conditions (presence of huge water to dry condition), and the object is under the earth surface. Whereas, if the velocity is above 0.19 m/ns or 0.200 m/ns and above represents false air events i.e. object is in air. This work can provide technical assistance to the beginners involved in the GPR based manpower development programmes.
Bandra is one of the major suburban stations in Mumbai. More than thousand suburban trains operation take place every day about 5 lacks commuters traveling through this station. Out of this 39% commuters approach the station by walk while 32% by bus 16% by Auto and 13% by other modes. The percentage to the station is nearly equal on the East and West. With the development of Bandra-Kurla Complex into last few years the commuters from BKC have substantial increased. Further, the Western Railway is developing the Bandra Terminal about 1 km north of the suburban station and operations from this terminal are also increasing every year above. The considering the Bandra Station Area Traffic Improvement Scheme has been included in the priority works under MUIP master plan. After considering several alternatives it is decided to develop Skywalks from Bandra (E) to Kalanagar and Bandra (W) to Hill road and Mohd. Raffi Chowk on priority. Skywalk form Bandra (E) to Kalanagar has been completed as pilot project.
