1 District-Wide Approach to Water Resource Modeling Water Resources Conference October 16, 2012 Phil Belfiori, RCWD Chris Otterness, HEI Mike Lawrence, HEI
2 Overview Rice Creek Watershed District Approximately 186 square miles Portions in 28 cities and townships 25 drainage systems, totaling 123 miles Approximately 50 lakes Variety of landscapes from very urban to very rural
3 The Need Updated flood inundation maps and base flood elevations for Regulatory Program Tools to help identify and complete projects in the District Better understanding of how water moves through the District Consistent documentation on survey and modeling to preserve investment far into the future
4 DWMP Overview District Wide Modeling Program (DWMP) Initiated in 2008 after the completion of a document titled District Wide Model Development This document outlined the goals and technical objectives for the DWMP Major goal: to update floodplain mapping and elevations for use in the Regulatory Program To achieve this goal the plan was to create detailed modeling of the entire District and make both the results and inputs readily available
5 Information Management
6 Products Created Modeling Specifications LiDAR and Survey data Hydrologic and Hydraulic Models of entire District Floodplain Mapping HydroViewer
7 Modeling Specifications Specifications were created for different modeling: hydraulic, hydrologic and water quality Standards were created for naming conventions, subwatershed development, requirements on documentation, and provide guidance on model input parameters Standards were developed for collecting survey data
8 Benefits: Specifications Specifications ensure consistency when models are developed by different practitioners Ensures that all data is well documented and can easily be shared with others Maintains investment in the work that was done, by avoiding unnecessary work in the future
9 Survey Geodatabase All survey data stored in consistent format Clearly see who, when, and in what datum the survey points were collected
10 Geo-referenced photos Slowly building a database of photos throughout the District Valuable in many areas of District activity Survey Geodatabase
11 High Resolution Topographic Data LiDAR data collected in 2008 Integrated into web viewers for easy access
12 Hydrologically Conditioned DEM Delineated 1,413 subwatersheds, average size 84 acres
13 Benefits: Survey and Topography Survey Geodatabase Quickly find elevations, culvert sizes, etc. Data are reusable Data are accessible Photos where available All data stored (projects, as-constructed, DWMP) Topography (LiDAR) Always checking elevations (e.g., permitting) Better mapped floodplains Conditioned DEM
14 Hydraulic and Hydrologic Modeling 12 SWMM models for public drainage systems into Rice Creek 2 SWMM models for the direct drainage into Rice Creek HEC-RAS model of Rice Creek
15 SWMM Modeling Used multiple proprietary SWMM models SWMM engine is public domain Very fine scale in some areas, subwatersheds as small as 2 acres Continuous simulation performed
16 Products: Hydraulic Model HEC-RAS model of Rice Creek, using combination of storage areas and crosssections Why HEC-RAS? Ease of modeling open channel flow Ease of flow inputs Viewing of profiles and velocities Ability to model sediment transport in future HEC-DSS used for inputting SWMM results HEC-RAS Model Layout
17 Structure Hydraulics For all structures on the public drainage system in the District. BENEFITS: Information about culverts on public drainage systems is quickly available to District staff. Information about replacing a culvert is available to cities and other entities.
18 Detailed floodplain mapping for public drainage system and Rice Creek Floodplain Mapping Better floodplains because of LiDAR acquisition and new modeling: Example on right is Upper Rice Creek and Crossways Lake Aids in Permitting and Identifies Problem Areas within the District Previous Mapping (Zone A) New Mapping
19 Mapped Floodplains
20 Benefits to Stakeholders: Hydraulics & Floodplains Better information for Permitting FEMA adopted Anoka County Floodplains Base Flood Elevations improve City planning Insurance questions easier to address Ability to very quickly evaluate new issues (e.g., culvert changes) Assessment of conveyance capacity
21 Understanding RCWD Hydrology
22 Understanding RCWD Hydrology
23 Lake Frequency Analysis Updated data 1% chance elevations used to map floodplains Used to verify hydraulics model Daily elevation frequency analysis. Use it to answer is my lake higher on average than normal?
24 Benefits: Hydrology Sources of the models are known Consistent model development and documentation Data for users (RCWD, Cities, others) Improved operational efficiency of District Engineer Use in drainage system repair reports Use in project designs (repairs / Capital Improvement Projects) Better lake level information Maximize project locations Intercommunity flows established
25 Runoff Volumes
26 Phosphorus Yields
27 Benefits: Volumes and Loads Planning level analysis Identify areas with higher runoff volume and yields Use to prioritize locations for implementation projects (e.g., TMDLs) Possible use in volume control analysis
28 HydroViewer very similar to existing Permit Mapper Allows easy access to model inputs and outputs All data shown can be queried Products: HydroViewer
29 Products: HydroViewer, cont. Each Model Node is displayed Each subwatershed can also be shown
30 Maintenance Challenges Need to keep track of changes in the District, otherwise models will be outdated and less useful Maintenance plan developed Product Description Maintenance GIS Library Model Library Survey Geodatabase HydroViewer A data dictionary describing the specific GIS layers, a link to the original data source and the applicable file names, and the actual GIS data. Input data, parameters derived from the input data, modeling reports, the hydrology, hydraulic and water quality models and the model results. Survey information collected through the DWMP, project completion, and public drainage system inspection and repair Modeling input and output data, including estimated peak runoff rates, growing season runoff volumes. Updated continuously as part of the project workflow and permitting processes. Updated continuously as part of the project workflow process and a review of permits with substantive changes in subwatershed boundaries and structures. Updated continuously as part of the project workflow process on a project specific basis. Data will be updated annually.
31 Challenges Spatial scale of analysis: Even though the model is detailed, there are limits to how the results can be used Floodplain mapping not in all areas

60 Project Discovery Quoting the Corrective Plan A Corrective Plan was formulated under the Interstate Compact It limits the elevation and placement of any agricultural levee within the reach below Grand Forks to State Route 317 Bridge. Finding 6 states, in order to protect the integrity of the plan, no roads can be raised within a defined effective flow area. Effective Flow area at Oslo: Intersection of Mn Hyw 1 and Highway 220 (Marshall County, Mn) to first T intersection just west of the Grand Marais River on ND Hwy 54. Defined by 43,000 cfs flood profile USACE Solution Interstate agreement to amend the Corrective Plan (NDSWC, MNDNR, Grand Forks, Walsh County, Middle-Snake- Tarmarac Rivers Water Resource Districts)
