This document summarizes a study that used GIS tools to redesign the Kotmara Dam on the Kas River in India. The study first delineated the dam's watershed area using topographic maps and QGIS software. Runoff was then estimated to determine the actual water storage available. The dam's design was analyzed and its hydraulic dimensions reassessed based on the updated watershed and runoff data. Three trial designs were modeled by increasing the dam height. All trials showed safety factors above minimum requirements, indicating the dam could safely hold more water if its height was increased. The study concluded QGIS provided a more accurate watershed delineation than manual methods. Redesigning the dam could improve its ability to meet water

Rainfall-Runoff Modelling using Modified NRCS-CN,RS and GIS -A Case StudyIJERA Editor
Study of rainfall and runoff for any area and modeling it, is one of the important aspects for planning and
development of water resources. The development of water resources and its effective management plays a vital
role in development of any country more particularly in India, which is an agricultural based economy. Hence it
is intended to develop a model of Rainfall and runoff to a river basin and also apply the methodology to Sarada
River Basin which has drainage area of 1252.99 Sq.km. The basin is situated in Vishakhapatnam district of
Andhra Pradesh, India. The rainfall and runoff data has been collected from the gauging stations of the basin
apart from rainfall data from nearby stations. MNRCS-CN method has been adopted to calculate runoff. Various
hydrological parameters like soil information, rainfall, land use and land cover (LU/LC) were considered to use
in MNRCS-CN method. The depth of runoff has been computed for different land use patterns using, IRS-P4-
LISS IV data for the study area. Based on the analysis, land use/land cover pattern of Sarada River Basin has
been prepared. The land use/land cover patterns were also visually interpreted and digitized using ERDAS
IMAGINE software. The raster data was processed in ERDAS and geo-referenced and various maps viz. LU/LC
maps, drainage map, contour map, DEM (Digital elevation model) have been generated apart from rainfall
potential map using GIS tool. The estimated runoff using MNRCS-CN model has been simulated and compared
with that of actual runoff. The performance of the model is found to be good for the data considered. The
coefficient of determination R2
value for the observed runoff and that of the computed runoff is found to be
more than 0.72 for the selected watershed basin.
Presentation highlights the potential of satellite data products, modeling tools and Smart-ICT platform to assist flood-based farming to enable rural people to overcome poverty and improve food productivity while reducing water consumption.
The project demonstrates for the last two flood seasons how satellite data can detect the extent and duration of flooding in various irrigation block and the authorities can make use of such information to know when and where the flood waters are reaching the farm fields and how many days it got inundated.

Quantitative evaluation and analysis of morphometric parameters derived from ...AM Publications
GIS has become a key source to understand the hydrological conditions of watersheds for the last few decades. Arc Hydro tool of ArcGIS has been proven its role in the automated extraction of drainage network and morphometric analysis from DEMs. The delineation of drainage network can be done either manually from topographic sheets or derived from Digital Elevation Model (DEM) data by means of computational methods. In the present work, ASTER DEM has been incurred to extract drainage network with the aid of Arc hydro tool. The Vaishali River basin of Madhya Pradesh has been taken as the study area. This study has been done primarily based on a geo-spatial software ARC GIS in which ARC HYDRO a tool has been used extensively. The quantitative evaluation and analysis of about twenty morphometric parameters has been done based on the linear, areal and relief aspects. The analysis has revealed that the Vaishali River basin is a fifth order basin showing dendritic drainage pattern with drainage density of 0.40 per km and stream frequency of 0.08 per km2. Low drainage density indicates the basin has not been much affected by structural disturbances while drainage frequency and very coarse drainage texture specifies low relief and porous, permeable rocks beneath the ground surface. The form factor, circularity ratio and elongated ratio suggest the basin shape as elongated. The area has low to moderate relief and slopes displays moderate relief ratios. It is concluded that this technique is not only reduces time but also provides valuable results which are very helpful for watershed management studies.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
