Schlumberger Water Services has used its experience in flood hazard management to assist governments and public organizations by providing reliable analysis of flood potential. This information is used to help clients evaluate the probable impacts and jurisdictional bounds needed to protect residences and businesses from negative effects. Schlumberger Water Services experience includes the following capabilities:
- Flood and drought frequency analysis
- Precipitation frequency analysis
- Snowmelt modeling
- Hydrologic modeling for Probable Maximum Floods
- Reservoir operation simulation modeling
- Water balance modeling and flood routing
- Hydrodynamic models coupled with GIS applications for flood hazard mapping and preparing floodplain management plans
Schlumberger Water Services projects demonstrating expertise in flood control and drainage include the following:
| Title: |
Flood forecasting model for Red River
|
| Location: |
Manitoba, Canada and North Dakota, USA |
| Client: |
International Joint Commission |
| Description: |
Schlumberger Water Services engineers developed a major flood forecasting model for the Red River on behalf of the International Joint Commission. The hydrodynamic model extends from Grand Forks, North Dakota to Selkirk, Manitoba, a distance of 280 km. The model was transferred to Manitoba Natural Resources who are using it in a real-time flood forecasting mode, with assistance from Schlumberger Water Services. Schlumberger Water Services was retained by the International Joint Commission to prepare flood inundation maps of the Red River for evaluation of agricultural damages. This required extending the MIKE 11 1997 and 1826 simulation runs and using MIKE 11 GIS to prepare ArcView shape files of flooded area every 12 hours over a three-month period. |

| Title: |
Floodplain management plan for the Pembina River
|
| Location: |
North Dakota, USA |
| Client: |
International Joint Commission |
| Description: |
The Pembina River is an international river that periodically overflows the border between the United States and Canada. To assist resolution of the flooding issues, Schlumberger Water Services was retained to develop a comprehensive hydrodynamic model of the river and analyze various flood control scenarios. The work included field investigations, flood frequency analysis, development and calibration of a hydrodynamic model using MIKE 11 and simulation of various flood control scenarios including setback dykes and construction of a floodway. The modeling approach was presented at a public meeting in the Pembina River Basin. |

| Title: |
Integration of Topographic Engineering Center Digital Elevation Model
|
| Location: |
North Dakota, USA |
| Client: |
US Army Corps of Engineers |
| Description: |
The Topographic Engineering Center of the US Army Corps of Engineers has developed a Digital Elevation Model (DEM) of the Lower Pembina River. Schlumberger Water Services was retained by the Corps to integrate the DEM with Schlumberger Water Services’s Pembina River MIKE 11 model. The work included handling very large data sets (over 1 Gb), which required writing specialized computer programs to extract data segments. The DEM was used to confirm cross-section elevations in the floodplain and to generate flooded area maps using MIKE 11 GIS. |

| Title: |
Red River Dykes cumulative impact assessment
|
| Location: |
Manitoba, Canada |
| Client: |
Manitoba Natural Resources |
| Description: |
Schlumberger Water Services completed a cumulative dyke impact assessment for Manitoba Natural Resources. The work included evaluation of 14 community ring dykes in the Red River floodplain and 2600 individual flood-proofing projects. The purpose of the evaluation was to determine whether the proposed projects would collectively have an unacceptable impact on water levels. The impact of the St Mary’s Road Dyke was investigated with and without the other projects, as it is located immediately opposite the Red River Floodway Inlet. A MIKE 11 model of the Assiniboine and Red Rivers was used to model the floodplain flow processes, with and without the proposed dykes. |

| Title: |
Nooksack River overflow hydrodynamic modeling
|
| Location: |
Washington, USA |
| Client: |
Cross Developments |
| Description: |
The Nooksack River flows from Mt Baker in Washington State to Bellingham, north of Seattle. Schlumberger Water Services carried out a hydrodynamic modeling study of Nooksack River overflows into Sumas Prairie to assess the impact on water levels of a proposed development. A MIKE 11 model was calibrated for the 1990 flood event and estimates were made of 100-year and 200-year overflows. The design floods were modeled with and without the proposed development and the impact on water levels assessed. |

| Title: |
Evaluation of Winnipeg area DEMs for Assiniboine and Red River floods
|
| Location: |
Manitoba, Canada |
| Client: |
International Joint Commission |
| Description: |
In recognition of Schlumberger Water Services’s capabilities in handling very large Digital Elevation Models (DEM), the International Joint Commission retained Schlumberger Water Services to evaluate a DEM developed for the Winnipeg area by a topographic engineering company. The scope of work included determining whether the DEM provided accurate detail for MIKE 11 modeling and preparing flooded area maps of the Assiniboine and Red River floods of 1997 and 1826 using MIKE 11 GIS and the new DEM. |
