Hydraulic Modeling Sample Clauses
The Hydraulic Modeling clause defines the requirements and standards for creating simulations of water flow and pressure within a given system or infrastructure. Typically, this clause outlines the methodologies, data inputs, and software tools to be used, as well as the level of detail and accuracy expected in the modeling process. For example, it may require the use of specific modeling software to predict how a new pipeline will affect existing water distribution. The core function of this clause is to ensure that hydraulic analyses are performed consistently and reliably, thereby supporting informed decision-making and minimizing the risk of design errors or system failures.
Hydraulic Modeling. Engineer shall develop a hydraulic model of the existing sanitary sewer collection system. This model will be used to evaluate the existing system for deficiencies and limiting service factors. Future growth projections will be included in the model to develop future growth areas and identify restrictions in the existing collection system.
Hydraulic Modeling. A hydraulic model of the South ▇▇▇▇▇▇▇▇▇▇▇ Creek will be developed using the HEC-RAS computer software. Channel cross sections will be spaced at approximately 500 foot intervals and will be based on data collected in Task 4. The hydraulic model will be used to estimate channel capacity and identify where capacity deficiencies exist. The HEC-RAS model will be developed using similar methodology as the 2006 ▇▇▇▇▇▇▇▇▇▇▇ Creek Master Plan.
Hydraulic Modeling. The Consultants subconsultant (Black & ▇▇▇▇▇▇) will complete modeling required for the Shepherd Hills BPS. They will utilize the model they have developed for the City’s Water Master Plan. The modeling runs to be completed are: • The 2025 model will consist of Low-Level Pressure Zone supply from ▇▇▇▇▇▇▇ Springs Water Treatment Plant (WTP) and Mountain View WTP. • The 2045 model will consist of Low-Level Pressure Zone supply from ▇▇▇▇▇▇▇ Springs WTP and the proposed East Side WTP. The 2025 and 2045 Master Plan developed demand scenarios will be used for this analysis, except for Shepherd Hills development area demand. The developer estimated Shepherd Hills 2025 and 2045 demand is different than the Master Plan estimated Shepherd Hills 2025 and 2045 demand. The Owner will provide the Consultant with the desired Shepherd Hills demand to be used for design in 2025 and 2045.
1.15.2.1. A meeting will be held with City, Consultant, and Black & ▇▇▇▇▇▇ to review system demands and determine demand for this study.
1.15.2.2. Sub-Task 1: North Rapid Evaluation and Flow Control Assumptions Modeling will be completed to identify the amount of flow from the North Rapid Service Area to the Shepherd Hills development. The following information will be determined:
1.15.2.2.1. Low demand period flow rates from North Rapid to ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (▇▇▇▇ and 2045 scenarios, 2 model runs)
1.15.2.2.2. Peak Hour flow rates from North Rapid to ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (▇▇▇▇ scenario only) with existing piping conditions (1 model run)
Hydraulic Modeling. The ENGINEER will perform the modeling efforts using Lee County’s current InfoWater models for the potable water and wastewater systems and we will use adICPR for localized stormwater system improvements Prior to final design, the ENGINEER will provide the model results and associated pipe and pump station sizing to Lee County for confirmation and acceptance of proposed pipe and pump station sizing. The following modeling efforts are proposed:
a. Potable Water – Update the existing pressure system hydraulic model for potable water to incorporate infrastructure proposed within the service area. To assist with this effort, the most current model will be obtained from Lee County. The ENGINEER will rely on the County to provide a calibrated model. No calibration efforts are proposed as part of this scope. The ENGINEER will utilize this model to perform final pipe sizing for the distribution piping. This effort will include:
1) Input of infrastructure proposed within the service area.
2) Identification of alternatives for evaluation.
3) Modification and updating of the model for demand projections within the service area.
4) Performing steady state model simulations to confirm required pipe sizes and routing of the potable water distribution piping within the service area.
5) Verifying pipe pressures and velocities meet applicable standards.
6) Identification of locations for connections to existing potable water system infrastructure, proposed developments and locations for stub-outs for future utility extensions.
7) Verifying hydrant locations and fire flow conditions are met.
8) Review and verify transmission piping locations and sizing.
Hydraulic Modeling. For each alternative, we will perform preliminary hydraulic modeling to assess potential water level impacts. We will leverage the existing effective FEMA 1D HEC-RAS model of the Heart River and update the model around the ▇▇▇▇’▇ Dam based on more current data that is available and any survey data that ▇▇. ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ 2/21/2025 is collected. This model will extend upstream to the ▇▇▇▇▇▇▇▇▇ and Queen City Dams and will extend downstream to the State Avenue bridge crossing. The model will use a preliminary representation of the dam geometry under each of the four alternatives. We assume that the discharge conditions for events ranging from the 10% annual chance to the 0.2% annual chance probability (e.g. 10-year, 100-year, and 500-year) floods will be taken from the effective FEMA Flood Insurance Study (FIS) for Stark County (dated August 2024). We will include a low-flow estimate based on available gage records and/or watershed assessment to determine the maximum water surface lowering that would be expected with any of the evaluated options. 1.2.4 and 1.2.5/1.2.6, respectively
Hydraulic Modeling. Consultant shall conduct hydraulic modeling of ▇▇▇▇▇▇ Creek in the vicinity of the subject property. The modeling will update the water surface profile of the 0.2% and 1% annual chance flood events and determine the extents of the regulatory floodway following established FEMA methodology.
Hydraulic Modeling. Consultant to provide defined planning and modeling work for to verify existing and future demands in support of optimized project designs.
Hydraulic Modeling. Engineer shall develop a hydraulic model of the existing water distribution system. This model will be used to evaluate the existing system for deficiencies and limiting service factors. Future growth projections will be included in the model to develop future growth areas and identify restrictions in the system. Included in this item are two (2) work sessions with Town Staff to achieve the following: Work Session No. 1: • Review the existing system model results; • Identify the most critical needed fire flows; • Identify service area additions that are likely to be included in the planning period; • Estimate the water demands on the system at the end of the planning period; Work Session No. 2: • Review the future system model results; • Review proposed capital improvement projects; • Prioritize capital improvement projects.
Hydraulic Modeling. Develop and calibrate a hydraulic model of the WWTP from the plant effluent City of Camas Wastewater Treatment Facility December 2022 Headworks, Primary Clarifier Improvements and Blower Pre-Design Page 4 Task 200 - Final Design
Hydraulic Modeling. No detailed hydraulic modeling is included. The consultant will complete basic transmission line hydraulics using a spreadsheet type of analysis evaluating pressure, velocity, and head loss in transmission mains. If areas of concern are noted, they will be identified. If modeling is later determined to be necessary, an amendment to this agreement will be required.
