Experimental Evaluation and Numerical Modeling for Flow and Solute Transport through Soil Column and Two-Dimensional Fractured Porous Formations

- DST New Delhi, PI – Dr. P. K. Sharma

Transport of reactive chemical in subsurface porous media is affected by various factors such as sorption, degradation in addition to the physical processes of advection and dispersion. Main objectives of this project are to estimate flow and transport parameters i.e. pore water velocity, dispersion coefficient, diffusion coefficient and sorption coefficient in different types of soil by conducting soil column experiment. Next, we will study the effect of layered soil on spatial concentration profiles. For this experiment we will use chemical tracer as chloride, arsenic, nitrate, lead and bacteria, etc. Afterwards, we will also conduct the experiment to investigate transport processes such as advection, dispersion, diffusion and sorption in fractured porous formation. Finally, we will attempt to develop model for one-dimensional soil column experiment and two dimensional fractured porous formations.

Suitability of Baggi Canal Road, Sundernagar for NTPC Works

- Consultancy Project

NTPC Koldam is constructing an Earth and Rock Fill Dam on river Sutlej for Hydro Power Generation. They have identified a Clay borrow area which requires use of about 3.1 km stretch of BBMB Canal Road, Sundernagar for transportation of clay to Dam Site. NTPC has requested BBMB authorities to give permission for use of above Canal road, Sundernagar for Clay Transportation by Heavy Trucks of 36 to 39 loads (including their own weight). The construction of this dam is of national importance. Government has already spent Thousands of Crores on the construction of this Dam which is still not completed and requires more clay. The present source of clay will be completely depleted within 2-3 months. Hence another source of clay is required. That is why exercise of transporting Clay through Baggi Canal Road was being explored. Baggi Canal Road is basically a service road of the canal. It is partly in cutting and partly in filling. In some portion, there are deep valleys also. Presently trucks up to 5 ton load are allowed to ply over this road. BBMB authorities are having apprehension that if heavy trucks are allowed to move, the road may fail leading to frequent accidents on valley side as well as canal side. In view of the above, Addl. Superintending Engineer, Hydel Channel & BG Division, BBMB, Sundernagar (HP) requested IIT Roorkee to examine the feasibility of plying of Loaded Heavy Trucks on Baggi Canal Road by carrying out design analysis to ascertain whether the banks of canal are able to sustain load of such loaded vehicles. The IIT Roorkee team inspected the road, performed the Benkelman Beam Test to assess the strength of road and collected the soil sample of the road side to find the CBR of the road subgrade. Based on the investigations, IIT Team gave the recommendations which were implemented by NTPC.


IIT Roorkee has continued to give major inputs to PMGSY as State Technical Agency (STA) for whole Uttarakhand and a part of Uttar Pradesh.

Pedestrian Behavior under Varied Traffic and Spatial Conditions

Sponsored by CSIR, New Delhi, PI – Dr. Satish Chandra

Traffic accidents related to pedestrians has become as major safety problem now-a-days. This is mainly due to lack of proper control over pedestrians movement in urban environment. This control will be possible only if a good pedestrian facility is provided. For the design of these facilities and understanding pedestrian movement an in-depth study of pedestrian behavior is required. This project aim is to study the behavior of pedestrians while interacting with traffic i.e. while crossing and under other spatial conditions like sidewalks, open places etc. For this data have been collected at 36 locations for sidewalk and crossing in different parts of the country for pedestrian speed, flow, risk and gap accepted. The analysis shows that walking speed on sidewalks is 1.07 m/s, 1.01 m/s and 0.91 m/s for young, adult and old pedestrians respectively, whereas the mean crossing speed for the same age group of pedestrians is 1.29 m/s, 1.12 m/s and 0.91 m/s respectively. The minimum safe gap between vehicles for pedestrian to cross a road (critical gap) was found to vary from 6.68 s to 11.50 s. Pedestrian crossing risk was found to be higher for older pedestrians.

Enhanced Transverse Mixing of Pollutants in Streams with Submerged Vanes

DST, New Delhi, PI – Dr. Z. Ahmad.

Understanding of mechanisms of pollutants mixing in streams, which are used as sink for industrial and municipal waste disposal, is essential for water quality management. A considerable effort has been made for modeling the process of mixing of pollutants in stream both theoretically and through experimentation. The mechanisms for mixing are the interaction of turbulent diffusion and shear dispersion due to mean velocity gradients. The problem of mixing of pollutants from a nalah or tributary carrying the effluent from a city can be modeled by transverse mixing process. To increase the secondary current for the enhancement of transverse mixing, it is desirable to have some structure, which increases the secondary current in that reach. Submerged vanes are suitable structure for this purpose. No study related to effect of artificially-induced secondary current on the transverse mixing has been conducted, so far. The present project is intended to study this aspect of transverse mixing. The outcomes of the proposed project will provide a technique for the enhancement of transverse mixing in the downstream of tributary carrying the effluent from a city, which would be useful for the management of water quality in the streams.

Energy Dissipation on Block Ramps

INCH, Ministry of Water Resources, New Delhi PI – Dr. Z. Ahmad

Block Ramps are grade-stabilizing structures of a stream. They represent steep and short sections of a channel armored with rocks producing high-energy dissipation. Ramps are naturalistic stream restoration structures used to guarantee the morphological continuity of the streambed and the biotic continuity of the watercourse. Studies till date have identified a great potential in ramps to be a viable energy dissipation unit. They offer a congenial alternative to the conventional energy dissipating structures when the protection of the morphology and ecology of the watercourse is of the primary importance, as in the present date of environmental concerns. It may find an efficient solution to avoid the building of big and expensive dissipater pools, cascades, drops etc., and protect the stability of the construction for major to minor hydraulic structures (Spillways, overflow dams and embankments, and other water resources structures). Drop structures and stepped cascades have been in use since the last 3000 years as energy dissipating units. The introduction of “Ramps” in the last few years in Europe, though still new to the country finds an exigent proportion to the country’s water resources & hydraulic technology domain. From a hydraulic perspective, ramps conduct the flow to a lower elevation producing high-energy dissipation. The dissipation is due to the localized variation of stream slope and the high roughness conditions exerted by the bed material. Critical flow condition occurs at the beginning of the ramp while a hydraulic jump forms at the toe. Energy dissipation on the ramps depends on the height of the ramp, size of the base material, size and arrangement of boulders on the ramp. Effect of row and random arrangements of the boulders has been investigated but how the staggered arrangement/pitching affect the energy dissipation of flow is not yet investigated. The present study is proposed to answer this question.




Year 2008-2009

Planning, Design and Implementation of Solid Waste Management System in a Hilly Town, Pauri (Uttarakhand)

Vermitechnology is tried for the recycling of solid waste. It is an eco-friendly method. It has been proved to be good for integrated waste (combined liquid and solid) management. Most commonly adopted worm for Vermicomposting is Eisenia fetida (Exotic species), which is to be imported from other area. If the conditions become unfavorable than this species goes down in the earth and may become dominant and cause some kinds of diseases.Hence, some indigenous earthworm species found in the area of UTTARAKHAND have been studied and found to be good degrader of organic rich solid waste material. Earthworm species were collected from various places/localities from some district of Uttarakhand. Thirteen species have been identified and out of these the three species Perionyx excavatus, Perionyx sensibaricus and Eutyphoeus gammiei have been found suitable for domestic solid waste, integrated with sewage, sugar mill waste, paper mill waste and can be better alternative for the Eisenia fetida. The end product that is vermicompost has better nutrient content than the compost prepared conventionally. The method has been found to be the best for the green manure produced by drum composting also .This has a great significance as now the emphasis is on organic farming. Also the crop yield is found to increase by use of this vermicompost. Once the beds are ready it takes about 15 days to get the manure.

Inter-city Travel Behavior of Residents in Higher Education Institutions

The above research project is aimed at understanding the inter-city travel patterns of different population groups residing in the campus. The three distinct groups are Faulty, students and non-teaching employees. The intercity travel may be made either with official purpose or purely as a personal visit. The data would be collected using different survey methods like paper based survey, email survey and PDA based survey. It will be a personal interview conducted at a household. The study would analyse the mode choices, their related travel attributes like travel time, travel cost, stopovers, persons accompanying, type of service, etc., and would correlate them to the household or personal characteristics. The analysis will highlight the travel needs with respect to the travel distances and travel purposes.

Development of Building Attributes using High Resolution Remote Sensing Data Set

The basic objective of this project is to use of high spatial resolution satellite data to identify building attributes to assessment the risk associated in the event of natural calamities such as earthquake and tornadoes. Quick Bird (0.6m spatial resolution) dataset for two regions in San Fransciso area (Earthquake prone) and Florida (tornado prone) have been selected for study. The satellite data has been processed using different image processing techniques to extract the shape and size of the building, the shape, size and type of roof, the utility of the building. Further, through image classification techniques the building material used for roof and exterior walls have been identified. The classified dataset has been stored in a GIS based database, which will be subsequently for identifying the risk associated earthquake or tornadoes. The accuracy of the procedure developed has yielded an accuracy of 93.23% in terms of defining various building related attributes.

Estimation of PWV using GPS

GPS signals get delayed by the particles present in the atmosphere. This can be estimated from GPS signal. Further, the delay caused due to ionosphere can be evaluated from of dual frequencies of GPS signal and subtracted from total delay to obtain the delay from troposphere. From tropospheric delay, the component of delay due to water vapor known as zenith wet delay (ZWD) can be obtained by eliminating ZHD from tropospheric delay. ZWD can finally be converted to perceptible water vapor (PWV) using Numerical Weather Model (NWM).
