This work report summarizes Amaljit Bharali's contributions in 2016 related to water resources, hydrology, and flood modelling in Northeast India. Major contributions included operational work on a Flood Early Warning System including hydrological modelling. Other work included database development, field surveys, and training. Research activities included urban flood modelling in Shillong and hydraulic modelling of flood prone rivers. Publications and conferences were also listed.
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. We have also showcased how flood forecasting tools can help downstream authorities to make operational planning including maintenance of irrigation blocks and early warning for local communities.

Runoff modelling using hec hms for rural watershedEditorIJAERD
Due to climate change it is very essential to do hydrological modelling. Reliable models are essential for planning,
developmental works, prediction and safety of the population. Hydrological models are used to determine catchment
discharge/flow through an efficient way. HEC-HM (Hydrological engineering centre Hydrological modelling system) is
one of hydrological modelling tool developed by United States army corps of engineer (USACE) for event as well as for
continuous simulations. Models, especially continuous simulations are useful for future predictions of stream flow due to
land-use changes or extreme events phenomenon. In this study continuous hydrologic modellingwas carried out using
HEC HMS modelling tool.
Deficit and Constant Loss methods with Clark transform methods were selected. The calibrated model (period
1986-1988) was validated with data set of the period of 2009-2013. Study concluded that the model recommended and
can be used for stated River as decision support tool in the design and operation.

There is a need for a water quality model for use in the Lake Victoria basin countries in East-Africa. The
region is characterised by data scarcity, a tropical climate and riverine, lacustrine tidal wetlands which form
an important buffer to riverine pollution of the lake. These characteristics of the basin form a challenge for
water quality models. The objective is to state the strengths and weaknesses of a potential water quality
model under these challenging conditions. This objective is executed with the soil water assessment tool
(SWAT) in a catchment of the Lake Victoria Basin as pilot area. The pilot area of the Mara river basin is
hydrologically complex containing tropical and plantation forest, savanna, grasslands, bi-annual agriculture,
shrublands and wetlands. It has varied soil types and bi-annual rain seasons
The study consist of literature research and flow simulation of the transboundary Mara river basin. The
model study aims to characterise the hydrology in the pilot area. The study includes a thorough analysis of
rainfall, stage and flow data. Model preparation steps include the use of weighted-area rainfall estimation
methods, climate model data and empirical derivation of soil input parameters. Discharge calibration
methods include multi-site calibration, by making use of an alternative objective function statistic for the
commonly used Nash-Sutcliffe Efficiency (NSE) called the Kling-Gupta Efficiency (KGE). The literature study
targets previous flow and water quality studies done in tropical or wetland areas, thereby looking to see how
these studies adapted to hydrological modelling with SWAT in tropical or wetland areas, and why theses
adaptions were made. The literature research also includes a comparison of wetland processes in SWAT
with the physical, biological and chemical processes as described in previous studies.
The Mara river basin flow simulation gave a satisfactory model performance for two out of three calibration
sites, thereby being able to give preliminary outputs on water-balance and other flow characteristics. During
research, a number of model, knowledge and data gaps were found to be critical for better understanding
the hydrological and water quality system workings in the Lake Victoria and Mara river basin. From the
model and literature study it is concluded that several issues on data scarcity and hydrological model
processes in the tropics can be overcome. These do not necessarily decrease model performance or
uncertainty in the SWAT model. However, wetland processes are oversimplified in SWAT. Modification and
coupled SWAT models yet have not been able to provide an alternative to the default model that adequately
represents the main flow, sediment and nutrients processes and fluxes that are present in Mara’s wetlands.

Succession “Losers”: What Happens to Executives Passed Over for the CEO Job?
By David F. Larcker, Stephen A. Miles, and Brian Tayan
Stanford Closer Look Series
Overview:
Shareholders pay considerable attention to the choice of executive selected as the new CEO whenever a change in leadership takes place. However, without an inside look at the leading candidates to assume the CEO role, it is difficult for shareholders to tell whether the board has made the correct choice. In this Closer Look, we examine CEO succession events among the largest 100 companies over a ten-year period to determine what happens to the executives who were not selected (i.e., the “succession losers”) and how they perform relative to those who were selected (the “succession winners”).
We ask:
• Are the executives selected for the CEO role really better than those passed over?
• What are the implications for understanding the labor market for executive talent?
• Are differences in performance due to operating conditions or quality of available talent?
• Are boards better at identifying CEO talent than other research generally suggests?
Each month, join us as we highlight and discuss hot topics ranging from the future of higher education to wearable technology, best productivity hacks and secrets to hiring top talent. Upload your SlideShares, and share your expertise with the world!

SyQwest Bathy-2010 Sub Bottom Profiler used in Tarbela Reservoir StudySyQwest Inc.
Hydrographic echo sounders are used to measure the depth to the seafloor by using the properties of acoustic waves. The principle of echo-sounders is basic - by measuring the two-way travel time between the acoustic waves transmitted on sea surface and those reflected at seafloor.
In this study, an integrated approach for hydrographic surveying is introduced and evaluated in terms of its efficiency in comparison with the traditional methods of hydrographic surveying. The approach develops an integrated environment of hydrographic surveying comprising human, hardware and software. The process of surveying starts from in-house planning using specialized geo-spatial softwares. Then, on site a combination of computer hardware, echosounder, differential global positioning system (DGPS), survey vessel and survey crew is made. Post-processing is performed after conducting a survey in order to improve quality of data by filtering errors and producing the end product like reservoir underwater terrain, development of reservoir stage-area and stage-storage relationships, etc. The study was applied to Tarbela Reservoir, Pakistan.

APPLICATION OF 1-D HEC-RAS MODEL IN DESIGN OF CHANNELSAM Publications
Flood occurs at Surat city frequently due to sudden release of water from Ukai dam in river Tapi. At the
time of floods in river Tapi, Surat city and surrounding regions are most affected. The city has faced many floods
since long back. Major flood event occurred in the year 1883, 1884, 1942,1944,1945,1949, 1959, 1968, 1994, 1998,
2002, 2006, 2007 and 2012. The carrying capacity of river is approximately about 4.5 lakhs cusecs (12753 cumecs) at
present. In this, stability of a segment of lower reach approximately 6 km length of Tapi river between Weir cum
causeway and Sardar bridge is evaluated for its carrying capacity and stability in response to discharge and slopes
using HEC-RAS software for past flood data. The study reach consists of 24 cross-sections. The hydraulics model,
HEC-RAS is employed to evaluate flood conveyance performance and also uniform flow computation is carried out.
In the present study existing storm drains are not only marked but based on the HEC-RAS water surface elevation
computation for various flood discharges, need of flood gates on the storm drains are also assessed. The
recommendations are done based on this study either to increase height of bank or construct a retaining wall at
certain sections along the study reach. The present study also recommends installations of flood gates on all the storm
drain outlets which are without flood gates. The width of river in no case be encroached as sections are sensitive high
floods.
Objectives:
Develop a replicable integrated model (methodology) for evaluating the extent and development potential of renewable (non-renewable) groundwater resources in arid lands, with the Eastern Desert of Egypt as a pilot site.
The model will be replicable for similar arid areas; North of Sudan, Tibesty, Yemen, and Saudi Arabia.
Building national capacities.

2. Major Contributions under NER-DRR
Activities in 2014
1. Flood Early Warning System (FLEWS) Operational Work
This operational project envisages a routine computation of the flood runoffs in the
project area catchments, then check with critical parameters that can lead to a flood
event. The primary responsibilities in the project include -
Preparation of HEC-HMS models
Collection of ground data
Running and analyzing HMS model results during FLEWS operational phase
Identification of RCs to issue flood alert
2. Post FLEWS Field survey of major flood prone rivers in Assam
Field survey was started as part of the post flood activities of FLEWS which will further
strengthen the capability of the FLEWS system. The primary aim was getting location of
WRD gauge sites, studying flood prone areas and conducting bathymetric survey
wherever feasible. In the first phase of work we surveyed the major flood prone rivers
of Dhemaji, Tinsukia, Jorhat and collected location of WRD gauge sites. Also, we studied
2013 Jiadhal embankment breach location, extent of the breach and the river course
change after the breach. We did GPS and Echo-sounder survey in Chumoni gauge site in
Noa-dihing, Doomdooma.
3. NER-DRR Centralized Database Generation and Integration for road network,
settlement/villages, census data Centralized Infrastructure database preparation
With the objective to carry out disaster risk reduction in entire North Eastern Region
(NER) under NER-DRR, a centralized database preparation work was taken up in NESAC.
The major tasks assigned to me for the state of Assam were -
Generation/Integration of Road Network
Generation/Integration of Settlement Layer (Village Points, Village boundary,
settlement-polygon-areas)
Census Data Integration with the Villages
Asset Mapping
This work has been completed for the state of Assam.
4. Development & Dissemination of web-based Spatial Decision Support Systems (SDSSs)
for FLOOD under NER-DRR programme
The primary objectives of the programme
i. Collate and compile all existing databases related to flood in a single platform.
3. ii. Create a decision support application for Disaster Management.
iii. Map-based queries and analysis in the geo-portal
iv. Damage and Vulnerability Assessment on the fly in the portal
As part of the work, FLEWS alerts for 2013 and 2014, Synoptic Weather Advisory, AWS
rainfall readings, flooded RCs (source: ASDMA) and probable inundated village layers
(from NRSC SAR data from 2007-2014 and other sources) were collated for web
dissemination. In this regard, Project Definition Paper (PDE) has already been submitted.
Also, the full flood database for 2014 is ready for integration in the SDSS. For the 2015
flood season, this work is still pending.
5. SBIK Level 1 Flood Zonation database generation For North Eastern States
As part of Space Based Information Kiosk (SBIK) project, identification and digitization of
major flood prone areas were done by combining information from various sources like
historical data, media and available flood zones from state WRD centres. Low lying area
identification was done with the help of contours generated from DEM. SAR data was
used to extract out inundated areas for Manipur and Assam, due to availabity of data in
these states.
Activities in 2015-2016
1. Pre-Monsoon Works:
All total 38 HEC-HMS models of Assam were built as an upgrade to the existing FLEWS
system. The primary work in the phase included:
Correction of digital river database: The existing river data available with NESAC
had been digitized keeping in view the major/large river systems. But accurate
flood plain representation and proper delineation of sub-catchments need the
details of minor channels which act as major flood discharge carriers during
monsoon.
Preparation of LULC and Soil data for model preparation: Previously the CN grid
for SCS Runoff module in HEC-HMS was created using four major LULC classes
which generalized the CN for various LULC classes. It was seen that CN
parameter gravely affected the discharge from catchment. Hence for
preparation of CN grid, LULC classes were broken down to 26 different classes
and soil classes viz. A,B,C,D were recomputed using texture, drainage pattern
and type of soil.
Catchment Delineation and model preparation using HEC-GeoHMS: The
catchment delineation procedure additionally included burning of corrected
major/minor river systems. Special care was taken for removing erroneous sub-
4. catchment polygons and outlets, merging and breaking too small/too big
polygons. Also, the river routing method was changed to Muskingum-Cunge
from Muskingum to account for ungauged catchments and also decrease input
data assumptions in the model.
Correction to newly built HEC-HMS models: The new models built after
delineation were further checked for erroneous connections and necessary data
for routing were fed. Model calibration procedure was not possible due to
unavailability of required data, hence utmost care was taken to prevent any
errors in the models.
Model Simulation changed from previously 24 to 48 hours to account for full
routing of bigger rivers and tributaries.
2. Operational FLEWS activities:
The operational phase of the project includes coordinating with team members in the
following works -
