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.

This paper presents the determination of net flows into Almatti reservoir from CWC data and reservoir data. From the study it can be concluded that the average flow in to Almatti will be 574.86 TMC, the maximum inflow will be 1196.8 TMC and the minimum flow will be 166.99 TMC. The flows in annual in deficit years may reduce by about 50 TMC but there is no variation in the good years in the good years as the storage effects will take care of this aspect during good years. It can be concluded that there will be reduction of flows in the June and July flows in the ultimate scenario except in very good years.

Hydrologic data generally consist of a sequence of observations of some phase of the hydrologic cycle made at a particular site. The data may be a record of the discharge of a stream at a particular place, or it may be a record of the amount of rainfall caught in a particular rain gage.
Although for most hydrologic purposes a long record is preferred to a short one, the user should recognize that the longer the record the greater the chance that there has been a change in the physical conditions of the basin or in the methods of data collection. If these are appreciable, the composite record would represent only a nonexistent condition and not one that existed either before or after the change. Such a record is inconsistent.
ICLR Friday Forum: Modelling of Future Flood Risk Across Canada (May 31, 2019)glennmcgillivray
On May 31, 2019, ICLR conducted a Friday Forum webinar lead by Dr. Slobodan Simonovic of Western University titled 'Modelling of Future Flood Risk Across Canada Under Climate Change.'
Climate change has induced changes in key climate variables and the hydrological cycle across Canada. With continuous emission of greenhouse gases, this trend is expected to continue over the 21st century and beyond. In this study, a macro-scaled hydrodynamic model is used to simulate 25 km resolution daily streamflow across Canada for historical (1961-2005) and future (2061-2100) timelines.
Future projections from 21 GCMs following four Representative Concentration Pathways (RCPs) were used for the analysis. Changes in the frequency and magnitude of historical 100-year and 250-year return period flood events and month of occurrence of peak flow are analyzed. Results obtained from uncertainty analysis for both return period flood events found that flood frequency will increase in most of the northern Canada, southern Ontario, southern British Columbia, northern Alberta, Manitoba and Saskatchewan. However, northern British Columbia, northern Ontario, Manitoba and northeastern Quebec will be facing decrease in flood frequency. Results indicate that 40%-60% of Canada’s 100 most populated cities including many prominent cities such as Toronto and Montreal are high at risk of increased riverine flooding under climate change.
Slobodan P. Simonovic is Professor of Civil and Environmental Engineering at the University of Western Ontario and Director of Engineering Studies at ICLR. Prof. Simonovic is globally recognized for his unique interdisciplinary research in Systems Analysis and has over 500 professional publications and three major textbooks. Prof. Simonovic was inducted to the Canadian Academy of Engineering in June of 2013.

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.
2. Modeling in the Choptank Watershed
Ryan M. Jones
NHD HUC 8 Watershed
Code: 02060005
3. Project Objectives
Explore ways to leverage the MARFC’s hydrologic
modeling and forecasting expertise to support
Choptank Habitat Focus Area Objectives.
Specifically evaluate modeling techniques to
support:
- Gridded runoff simulations and forecasts
- Fertilizer application decision support
- Sediment simulations and forecasts
4. Previous Work: Choptank Literature Review
• Time Series Analysis
• Models
– General Water Loading Function (GWLF)
– Hydrologic Simulation Program – Fortran (HSPF)
5. HSPF – Hydrologic Simulation Program -- Fortran
• Simulates hydrology, nutrients, and sediment
• Used to model the entire Chesapeake Bay
Watershed
• Used for regulatory purposes, evaluating the
impacts of land use change and the impacts of
best management practices (BMPs)
6. GWLF – Generalized Water Loading Function
• Comparable to HSPF
• Typically use coarser temporal data
• Developed by Dr. Douglas Haith at Cornell
University in collaboration with the USEPA
• Used for assessing Total Maximum Daily Loads
(TMDL)
7. What is new to our approach?
• High Resolution Multi-sensor Precipitation
Estimates from gages and radar: 4 km2, 1 hour
resolution
• Gridded, spatially-distributed hydrologic
model
• Hydraulic Routing
• Ability to forecast – deterministic or
probabilistic
9. Hydrologic Models Run Using the Office of
Hydrologic Development (OHD) Research
Distributed Hydrologic Modeling (RDHM)
Software
• Gridded NWS Snow – 17
• Gridded Sacramento model with Soil Moisture
Accounting (SAC – SMA)
• Hill-slope and Channel Kinematic Wave Routing
10. Why we expect success
• RDHM models performed well in OHD’s Distributed
Model Intercomparison Projects
• RDHM land-use and soil-based parameterization
techniques have proven viable
• RDHM runoff estimates correlate well with USDA
runoff estimates in the Mahantango Creek
experimental watershed in PA
• Fertilizer Forecaster Capability – Collaborating with
Penn State and the USDA
• Wisconsin Department of Agriculture, Trade,
and Consumer Protection already has a
similar runoff advisory tool that uses NWS
forecasts

11. A lumped Model, such as the Sacramento Model, simulates the
hydrology of a region of interest with homogeneous or “lumped”
parameters.
Watersheds boundaries were created
from HUC 14 watersheds to match
gage locations
12. Distributed hydrologic models discretize the area of interest
into uniform cells. Each cell is like a small lumped model. We
are currently using a 2km by 2km grid.

CSSAS DEM
There were some issues with this DEM that we
tried to overcome with the NHD DEM. There is
some great bathymetry data here, but it does
not extend upstream as far as we need.
20. What is HEC-RAS?
• USACE Hydrologic Engineering Center – River Analysis System
(HEC-RAS)
– A multi-purpose 1D river modeling system for steady flow,
unsteady flow, sediment transport, and water quality
modeling.
• Steady flow
– engineering design
– static inundation maps
• Unsteady flow
– real time forecasting
– characterizes dynamic effects, e.g.
• Rapid flow changes
• backwater due to river confluences
• tides
• gate opening/closing, levee overtopping, etc.
21. Why we expect success
• HEC – RAS is an industry standard river
hydraulic model
• NWS has collaborated with USACE to integrate
HEC-RAS components into the MARFC’s
operational forecasting software – The
Community Hydrologic Prediction System
(CHPS)

25. Lateral Inflows
Using the downstream boundary condition
as an outlet point, RDHM was used to
determine the hydrologic flows to the river
network modeled. These outputs were
processed and then used as HEC-RAS model
inputs for each reach averaged over the full
length of each respective reach.
30. Risks with our HEC-RAS model
• Limited Data to calibrate HEC-RAS model
• May need more accurate bathymetry data
• More complex models may be desired for
some users
• Don’t yet know the required accuracy for the
model applications
32. Who Cares?
• Farmers – save money on fertilizer and
potentially avoid fines for nutrient loading
• Oyster Restoration Planners – reduction of risk
in oyster restoration projects
• Fisherman – better catch, increased
biodiversity
• Recreationists – improved water quality will
allow them to enjoy the estuary
