Tristen is pursuing a Master’s in Hydraulic Engineering at Colorado State University. He received his Bachelor of Science degree in Civil Engineering from the University of Minnesota Duluth in 2019. In his free time, Tristen likes to mountain bike, hike, camp, and travel to new places. Tristen’s research is to evaluate geomorphic changes within the Montaño Reach of the Middle Rio Grande, which extends from Montaño Road in Albuquerque, NM to the Isleta Diversion Dam in Bosque Farms, NM. Using topographic data, a 1D HEC-RAS hydraulic model was created to relate hydraulic conditions (velocity and depth) to suitable habitat for the endangered Rio Grande Silvery Minnow. The hydraulic model results paired with aerial imagery are used to generate habitat maps – A map showing the areas of available habitat for each life stage of the Silvery Minnow. Tristen’s research will be used to help with conservation efforts for the Silvery Minnow. |

Sidoardjo mud flow is a disaster that started on
May 29, 2006 at drilling point of Lapindo Brantas Inc.
at Sidoarjo, East Java, Indonesia. This mud
flow acts like a mud
volcano and spouts a volcanic mud from
under the earth surface. Until
March 22, 2007, the
mud flow has drown at least 650 ha and caused many
resident to evacuate based on data from the National
Mudflow Disaster Management Team. The mud flow is
predicted to last for at least 30 more years. In recent years, the average discharge
of mud flow is approximately 50,000 m3/day. To mitigate the damage from Sidoardjo mud
flow, the Team took an
action to discharge
the mud to Madura Strait through Porong River. The purpose of this research is to determine the
optimal sediment concentration at Porong River to
maximize the sediment transport capacity of the Porong
River, considering the characteristics of the mud as
non-Newtonian fluid, yield strength, fall velocity and
discharges in Porong River and also propose the
storage management strategies to mitigate the mud
accumulation problem. |

Ted is using HEC-RAS, a 1-dimensional hydraulic model, to determine the water surface elevation profiles for the Bosque reach of the Middle Rio Grande. His analysis includes simulations for 25 flow discharges varying in increments of 200 cfs up to 5,000 cfs. This analysis is to provide a better understanding of the historical overbanking throughout this reach. To achieve this, Ted is repeating his analysis with four different bed geometry conditions based on HEC-RAS model geometries for 1962, 1972, 1992, and 2002. These HEC-RAS models, in conjunction with aerial photographs analyzed using a GIS, will aid in his analysis. A total of 100 different hydraulic simulations will be completed to be analyzed in his reach report. |

Brianna Corsi is pursuing a master’s degree in Hydraulic Engineering at CSU. She completed a bachelor’s degree in Environmental Engineering at CSU in 2017 before starting her work as a Hydraulic Engineering Consultant at Ayres Associates in Fort Collins, CO, where she became a licensed PE. She returned to CSU as a graduate student in 2021 to pursue her interest in river mechanics, sediment transport, and riverine ecology. Brianna
is teaming with Chelsey Radobenko to evaluate geomorphic
changes within the Bernalillo Reach of the Middle Rio
Grande, which extends from HWY 550 in Bernalillo downstream
to Montaño Road in Albuquerque. The goal of the project is
to relate hydraulic conditions to suitable habitat for the
endangered Rio Grande Silvery Minnow and to evaluate changes
in habitat availability over time. As part of their
research, Brianna and Chelsey are using historical aerial
imagery and topographic data to develop a 1D hydraulic model
using HEC-RAS. Results from the model are then exported into
ArcGIS Pro to spatially evaluate habitat availability for
each of the minnow’s life stages.

Susan
received her B.S. in Food, Agricultural and Biological
Engineering from The Ohio State University in 2005. In 2006
she began working for Mussetter Engineering Inc., now Tetra
Tech, in Fort Collins, Colorado. She has been working
part-time towards completing her M.S. in Hydraulic
Engineering under Dr. Julien at Colorado State University.
She was granted her Professional Engineering (PE) license in
June 2011. In her free time Susan enjoys running, snow
skiing, traveling and spending time with her husband and two
feisty sons. Her
work at Tetra Tech has included various modeling tasks on
the San Joaquin River in support of the San Joaquin River
Restoration Program since 2007. These models include
updating one dimensional step backwater models from HEC-2 to
HEC-RAS for large scale analyses as well as using RAS 2D and
FLOW 3D models for more detailed hydraulic analyses to
support the design of structures to improve fish passage.
Her most interesting work on the river includes sediment
transport modeling using HEC 6T and HEC RAS mobile boundary
models considering the impressive amounts of subsidence the
SJR experiences. Her research for her Plan B tract of the
River Restoration/Hydraulic Engineer M.S. program at CSU is
related to the impacts of subsidence on the sediment
transport in the San Joaquin River system. |

Estimates of extreme floods and probabilities are
needed for hydrologic engineering and dam safety risk
analysis. Physically-based, distributed watershed models are
used
as
an avenue to estimate extreme floods, and as a basis to
extrapolate frequency curves. This research focuses on applied
hydrology and hydraulics of extreme floods on large watersheds. The main elements of this 
research include improving and using a
two-dimensional, physically-based rainfall-runoff model (CASC2D)
to estimate extr
eme
floods and probabilities for dam safety on a large (12,000 km2)
watershed, the Arkansas River above Pueblo, Colorado. New
tools have been
developed, including a channel mesh generator, so the model can be
applied at this scale. The main research goals are to:
demonstrate that CASC2D can be used to simulate extreme floods on
large watersheds; and add new process components, including
extreme storms and initial conditions, so that CASC2D can be used
to develop a flood frequency curve. In addition, we are
conducting sensitivity studies to examine: the spatial
distribution of storm rainfall with area and elevation; storm
duration; initial soil saturation; and channel floodplains; and
their effects on the model flood frequency curve extrapolation,
hydrograph shape, timing, peak and volume.
Caitlin is a Master’s student
studying hydraulic engineering at Colorado State University. She
obtained her Bachelor’s degree in Ecological Engineering from
Oregon State University in 2019. She is most interested in a
career in stream restoration or river engineering. Caitlin’s
research has been focused on determining where critical habitat is
along the Rio Grande for an endangered species of fish known as
the Silvery Minnow. Currently, her work has focused on assisting
with the creation of a process linkage report between Isleta and
San Acacia reaches. This report will draw connections between
geomorphology, morphodynamics, hydrology, and biology that can be
used to define suitable habitat for the Silvery Minnow.

intrusion in the estuary and prevent a
large flood due to high tides. The channel of Nakdong River was
designed to convey a design flood of 18,300 cubic meters per
second. The estuary barrage impacts the Lower Nakdong River in the
following fields: hydraulics, hydrology, sedimentation,
water-quality and stream ecology. Especially, because of the
construction of the barrage, the Lower Nakdong River has
experienced sedimentation problems requiring dredging operation
annually. The primary purpose of the dredging operations is to
maintain the conveyance capacity of the channel in the event of a
large flood combined with high water levels during high tides. The
recent historical record shows dredging volumes of about 400,000
cubic meters of dredged material per year. The material dredged is
primarily non-cohesive very fine sand.

The purpose
of this project was to update this database with the most recent
possible data, using sources such as the U.S. Bureau of
Reclamation office, U. S. Geological Survey, and the USBR reports.
The data, analyses for each reach studied in the Middle Rio
Grande, and the reports themselves were organized into an
interactive database DVD that can be accessed like a webpage.
Through this, it is possible to view analyses from each reach of
the Rio Grande, each report, and the theses and dissertations
written by the students who have worked on this project for the
past several years.

Young-ho Shin will take the analysis effects on downstream river channel using aerial photographs which
taken before and after dam construction. The study focuses on the
aspect of water, sediment and vegetation interaction in the sand bed channel
where the river flow is regulated by upstream dams, in order
words, hydro-geomorphologic changes in a sand bed channel and thus
vegetation expansion on the sandbars in the channel by changes in
the flow regime. The study area is the Nakdong River in Korea.
This river
is the longest river in South Korea with its river length of
506km. The basin area of the river is 23,394km2, the second
largest after the Han River (32,200km2). It locates in the south
east of the Korean Peninsula and generally the river flows from
north to south. The riverbed is composed mostly of sands except in
the far upstream in the mountain area where it is composed of gravel and cobble. In the river basin,
dams have been built since 1970’s starting from the Andong Dam in
1976. Since then, more major dams including the Imha Dam (completed in 1991)
and Hapcheon Dam (completed in 1988) have been built for flood
control, water supply and hydroelectric power generation. Also,
estuary barrage which is located at the end of Nakdong River have
been built to reduce salt-water intrusion and prevent a large
flood due to high tides.

To meet this need, a numerical model to
simulate the transport and fate of chemicals across watersheds is
under development. The model development effort focuses on surface
water hydrology with an emphasis on the transport and fate of
particle-associated chemicals. A computer code that integrates the
most critical hydrologic, sediment transport, and chemical
transport and fate processes into a single framework was developed
(Figure 1). This new code is called the Two-dimensional Runoff,
Erosion, and eXport (TREX) model and is based on Colorado State
University’s CASC2D watershed model with chemical transport and
fate processes from the USEPA WASP and IPX series of stream water
quality models.
I
am a part-time graduate student in hydraulic engineering at
Colorado State University. Both Oregon State University and CSU
felt obliged to offer me a bachelors and masters degree in civil
engineering, respectively. In between school and work I managed to
become a licensed professional engineer in Oregon and a registered
professional hydrologist through the American Institute of
Hydrology. In order to insure that my graduate studies progress at
a glacial pace, I currently work as the forest hydrologist on the
White River National Forest in Glenwood Springs.
